6 Tips for Choosing a Chemical Risk Management Consultancy | Hazmat Line

Allan Gotsis — Fri, 13 Nov 2026 16:46:38 GMT

In today’s industrial and business environment, chemical risk management has become a priority for companies of all sizes and sectors. Organizations that deal directly or indirectly with chemicals, whether in manufacturing, storage, transportation, or use, must comply with strict regulations and ensure the health and safety of their employees, the community, and the environment.

However, implementing effective chemical risk management practices is not always simple. It requires technical knowledge, constant updating on legislation, and the ability to anticipate and control potential hazards. For this reason, many companies choose to hire specialized consultancies that can provide tailored guidance and structured solutions.

The challenge, however, lies in choosing the right consultancy. Not all providers offer the same level of expertise, and the decision should go beyond cost considerations. The consultancy you select will play a strategic role in the sustainability of your operations and in protecting your company’s reputation. To help with this process, here are six essential tips for choosing a chemical risk management consultancy.

1. Check the Consultancy’s Experience and Technical Expertise

The first factor to analyze is the consultancy’s background and professional qualifications. Chemical risk management requires a deep understanding of industrial processes, toxicology, occupational safety, and applicable legislation.

Look for companies that:

Have professionals with specific training in chemical safety, occupational hygiene, and environmental management.
Can demonstrate proven experience in projects similar to your company’s activities.
Keep up with updates to standards and environmental regulations.
A consultancy with consolidated experience will not only identify risks but also propose practical and innovative solutions, adapted to your reality.

2. Analyze Knowledge of Standards and Legislation

Chemical risk management is highly regulated. The consultancy you choose should have up-to-date and in-depth knowledge of all relevant local, national, and international regulations. This includes standards from agencies such as the Occupational Safety and Health Administration (OSHA) in the US, the European Chemicals Agency (ECHA) in the EU, and other country-specific agencies. In Brazil, for example, companies must comply with occupational health and safety standards (NRs), ABNT technical standards, and the requirements of ANVISA and IBAMA.

Therefore, when choosing a consultancy, ensure that the team:

Has up-to-date knowledge of Brazilian and international legislation;
Offers support for the preparation of Safety Data Sheets (SDS) and labeling in accordance with the Globally Harmonized System (GHS).
They can help align occupational safety programs with regulatory requirements.

A good consultant will not only help you comply with these regulations but will also proactively identify potential future regulatory changes that may impact your operations.

3. Evaluate the Consultancy’s Methodology and Tools

Each consultancy has its own way of diagnosing and controlling risks. Before hiring, ask how the company conducts its analyses and what methodologies it uses.

Some important aspects to consider:

Does the consultancy conduct Preliminary Risk Analysis (PRA), HAZOP studies, or Occupational Risk Analysis (ORA)?
Are modern tools, such as specialized software for chemical risk management, used?
Does the consultancy adopt digital platforms to monitor risks and generate real-time reports?

Innovative methodologies and technological tools can increase the accuracy of risk identification and optimize decision-making.

4. Seek References and Case Studies

A reliable way to assess the quality of a consultancy is to learn from other companies that have used its services. Request references, case studies, or success stories.

By analyzing previous work, you can understand how the consultancy operates in practice:

Did it achieve measurable results, such as reducing accidents or improving compliance?
Was the service adapted to the client’s reality or based only on generic models?
Was there follow-up after project implementation?

References not only validate the consultancy’s competence but also provide insights into its ability to maintain long-term partnerships.

5. Assess Communication and Training Capacity

Chemical risk management involves people at all levels of the organization. It is useless to have technical reports if employees do not understand or apply preventive measures.

Therefore, the consultancy must also be able to communicate clearly and promote training. Good indicators include:

Offering courses, workshops, and practical training on chemical safety.
Producing accessible materials for operators, technicians, and managers.
Acting as a partner that clarifies doubts and guides decision-making.

A consultancy that invests in communication and knowledge transfer helps foster a safety culture within the company.

6. Compare Cost-Benefit and Service Customization

Finally, it is essential to analyze the consultancy’s cost-benefit ratio. The lowest price is not always the best option—especially when dealing with chemical risks, where failures can result in serious accidents, legal liabilities, and financial losses.

When comparing proposals, consider:

Does the consultancy offer a package of customized services or just standardized solutions?
Is there flexibility to adapt to the company’s size and sector?
Are there options for continuous monitoring, not just punctual services?

The ideal consultancy is the one that balances technical quality, financial viability, and commitment to your company’s goals.

Choosing a chemical risk management consultancy is a strategic decision that goes beyond mere regulatory compliance. It is about ensuring the safety of people, protecting the environment, preserving company assets, and maintaining competitiveness in the market.

By following the six tips presented—checking experience, analyzing knowledge of standards, evaluating methodologies, seeking references, valuing communication, and considering cost-benefit—you will be better prepared to select a consultancy that acts as a true partner in your company’s growth and sustainability.

Chemical risks are complex, but with specialized support, they can be controlled effectively. Investing in the right consultancy is not an expense, but a guarantee of safety, compliance, and trust in the future.

If PHMSA Inspected Your Company Today: Would You Pass? | Hazmat Line

Cora Chebat — Fri, 13 Nov 2026 16:46:37 GMT

On November 20, 2025, the Pipeline and Hazardous Materials Safety Administration (PHMSA) released a memo that shifts how it prioritizes inspections and enforcement actions. For companies that manufacture, ship, package, or transport hazardous materials in the United States, this memo provides valuable insight into PHMSA’s current inspection and enforcement focus, making it an important resource for inspection readiness.

What Changed in PHMSA's Enforcement Approach?

The memo from the Office of Hazardous Materials Safety (OHMS) emphasizes targeting inspections and enforcement where they provide the greatest positive impact on hazardous materials safety, while avoiding overly broad or novel interpretations of regulations.

In practice, this means PHMSA inspections will be increasingly risk-based rather than purely random. The memo identifies specific inspection priorities, outreach initiatives, and enforcement standards that regulated entities should understand and prepare for immediately.

PHMSA's Strategic Priorities: What Companies Should Know

PHMSA is focusing on three key areas: outreach, inspections, and enforcement standards.

Outreach Priorities

PHMSA emphasizes proactive engagement to improve compliance before enforcement becomes necessary. This includes strengthening communication with hazmat shippers, clarifying packaging selection requirements, and promoting accurate classification of materials prior to shipment. Because packaging and classification remain among the most common sources of violations, staying informed is critical.

Companies that actively participate in PHMSA webinars, seek regulatory guidance, and implement good-faith compliance practices are generally less likely to have errors or non-compliance issues. By staying informed and applying best practices, these companies reduce the risk of violations before an inspection ever occurs.

Inspection Priorities

PHMSA’s inspections now focus on operations that present the highest safety risk or recurring compliance concerns. Priority targets include:

General hazardous materials shippers and offerors
Cylinder requalification and manufacturing facilities
Drum manufacturing and recertification operations
Lithium battery shippers
E-commerce platform shippers with potential undeclared hazardous materials

PHMSA also emphasizes follow-up inspections for companies with prior violations to verify that corrective actions were implemented. Inspections are increasingly data-driven and risk-based, rather than routine or evenly distributed.

Enforcement Standards

PHMSA’s enforcement approach is now timely, consistent, and risk-focused. Violations posing the greatest risk to public safety, the environment, or transportation security receive enforcement priority. By leveraging trend analysis and case management data, PHMSA identifies recurring violations and emerging risks, meaning companies with compliance gaps or a history of violations should expect increased scrutiny.

What PHMSA Will Likely Request During an Inspection

While the memo doesn’t list specific records, PHMSA inspections routinely review documentation that demonstrates compliance. Based on standard practices, inspectors may request:

For Hazmat Shippers and Offerors:

Hazmat Employee Training (49 CFR 172.704)

Initial and recurrent training (every 3 years) covering: general awareness, function-specific tasks, safety, and security awareness
Training records must be maintained while employees perform hazmat functions and for 90 days afterward
Documentation of training completion and testing/certification

Shipping Papers and Documentation (49 CFR 172.200–205)

Proper shipping name, hazard class, identification number (UN/NA)
Packing group and total quantity
Emergency response information (49 CFR 172.602), including a 24-hour emergency contact number
Retention: 1 year minimum (3 years for hazardous waste shipments)

Packaging Selection and Certification (49 CFR 173)

Evidence that packaging was selected according to the Hazardous Materials Table (49 CFR 172.101)
Packaging specifications and certification documents
Requalification records for reusable containers (cylinders, IBCs, etc.)
Proof that packaging meets performance standards for materials shipped

Security Plans (49 CFR 172.800–804, if required)

Written security plan for companies shipping high-consequence materials
Security awareness training documentation
Personnel security background checks (if applicable)

Incident Reports (49 CFR 171.15–16)

Immediate notice of certain hazmat incidents
Written incident reports filed with PHMSA (Form F 5800.1)
Internal incident investigations and corrective actions

Attention: Failure to provide requested documentation promptly—typically within minutes—can itself indicate inadequate safety management controls. Missing multiple documentation categories may be seen as a systemic deficiency.

Conducting Your Compliance Self-Assessment

Don’t wait for PHMSA to discover gaps. Here’s how to evaluate readiness:

Immediate Assessment (This Week)

Emergency Response Information: Test your 24-hour emergency contact and make sure your provider has your most up-to-date information, including the correct contact person, current Safety Data Sheets (SDS), and relevant shipping details.
Training Status: Identify hazmat employees whose training expires within 90 days, verify records are accessible and complete, and confirm that training covers all four required areas.
Recent Shipments Audit: Review the last 10 shipments to ensure shipping papers are complete, packaging selection matches Hazardous Materials Table requirements, and emergency contacts are correct.

Comprehensive Assessment (This Month)

Create a master list of all hazmat employees with training dates and expiration tracking
Review your training program to ensure it meets 49 CFR 172.704 requirements
Implement a compliance calendar for recurrent training, container requalification, and other recurring obligations
Document procedures and responsibilities for packaging selection, classification, and shipping paper preparation

Ongoing Compliance Activities

Subscribe to PHMSA regulatory updates, safety notices, and Federal Register publications
Conduct quarterly internal audits of shipments, training records, and emergency contacts
Participate in industry associations, webinars, and networking for best practice sharing
Engage professional consultants for complex compliance areas as needed

The Strategic Value of Compliance

Being compliant with hazardous materials regulations is about more than avoiding fines or enforcement actions. At its core, compliance exists to protect people, property, and the environment from the serious risks inherent in the transportation of hazardous materials.

Companies that maintain strong safety management systems, deliver thorough employee training, and keep accurate, accessible documentation are actively contributing to this mission, reducing the likelihood of accidents, spills, or other harmful incidents. Conversely, gaps in compliance or reactive approaches don’t just increase regulatory scrutiny—they increase the risk of events that can cause injury, environmental damage, and significant operational disruption.

Updates on Mexico’s Circular Economy Law | Hazmat Line

Melissa Owen, AMBIENTELEGAL — Fri, 13 Nov 2026 16:46:34 GMT

Companies operating across borders in Latin America - including those manufacturing, importing, distributing, or transporting chemical products - need to pay careful attention to Mexico’s new Circular Economy Law.The title of the Law is deceptive because it goes well beyond waste and recycling. It signals a policy shift toward addressing substances of environmental concern, what it refers to as “toxic and contaminating substances.”

Regulatory affairs professionals, product stewardship teams, SDS authors, transport compliance specialists, and emergency response coordinators should monitor how this framework evolves, as it may influence not only environmental policy but also broader chemical management practices, hazard communication, and long-term compliance strategies in Mexico.

The law approaches this issue in several ways

First, the future National Circular Economy Program—which will identify covered products and sectors—should promote productive processes that reduce the use of toxic substances.
Second, the Program is expected to foster Circular Design by minimizing the use of toxic and contaminating substances at the production stage.
Finally, the government is tasked with establishing targets for substituting toxic substances with non-toxic alternatives.

The law itself does not immediately ban or list substances, but it clearly mandates future policies, EPR implementation agreements, and targets that aim to:

Reduce the use of substances of concern
Promote substitution with safer alternatives
Embed these expectations into product design and lifecycle managemen

Any concrete restrictions will therefore come later—through the National Circular Economy Program, EPR Implementation Agreements, and future NOMs (mandatory technical standards).

The Disconnect: “Toxics” vs. Hazardous Substances

The law’s use of the term “toxic and contaminating substances” reflects a broader and longstanding challenge in Mexico’s environmental framework: the absence of a modern, comprehensive approach to hazardous chemical substances. These terms are imprecise and limiting, and their use perpetuates gaps already present in existing environmental legislation. By contrast, several Latin American countries—including Chile, Colombia, Brazil, and Peru—have moved toward modern chemical management regimes (often referred to as “LatAm REACH") all of which recognize the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) as a foundational element. The Circular Economy Law could have adopted a more contemporary approach by referencing hazardous substances and aligning explicitly with the GHS. While the United States still uses the term “toxic” in its chemical framework, that statute -the Toxic Substances Control Act (TSCA) - dates back to 1976, long before the development of the UN GHS.

The terminology choice points to a lack of regulatory coordination. Companies need to understand that the Circular Economy Law addresses substances at a policy level using terminology that is disconnected from modern chemical management framework. This outdated terminology is in stark contrast to the reality of operational compliance in Mexico which is already based on the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). Mexico’s workplace safety regulations, transport requirements for hazardous materials, and certain emerging product standards are GHS-based and consistent with UN recommendations. The fact that technical compliance mechanisms are increasingly aligned with international standards leads us to assume some lack of coordination between the legislature that developed the new law and the regulators involved in day-to-day chemical regulations in the country. In this context, the Circular Economy Law feels like a throwback to earlier environmental laws such as the LGEEPA (General Law on Ecological Equilibrium and Environmental Protection).

Next Steps

Future instruments adopted under the Circular Economy Law - including the Regulation, National Program, EPR agreements, and NOMs - will ultimately determine how substances of concern are addressed in practice.

E-Commerce Hazmat: Do You Need a 24/7 Emergency Number? | Hazmat Line

Cora Chebat — Fri, 13 Nov 2026 16:46:33 GMT

A bottle of perfume does not stop being flammable because it is sold for household use. Aerosol sunscreen and some cleaning products also present transportation hazards. For an online seller, those hazards affect how the order can leave the warehouse and whether someone must be available to provide emergency information along the way.

The starting answer under U.S. transportation rules is straightforward: a hazardous material properly offered under applicable limited quantity provisions does not require the emergency response telephone number in 49 CFR §172.604. Otherwise, the number is generally required unless another exception applies. Establishing which provisions fit your shipment takes a closer look at the product, packaging, and route.

Start with the product

Ask the manufacturer or supplier for transportation information covering the exact formulation. A current Safety Data Sheet (SDS) can help: Section 14 may identify the UN number, proper shipping name, hazard class, and packing group. The UN number identifies the transportation entry; the class describes the hazard. Where assigned, Packing Groups I, II, and III indicate high, medium, and low danger.

Ordinary paper notebooks shipped by themselves are an example of unregulated merchandise. A cleaning product needs its own assessment; its household label cannot establish whether it is flammable, corrosive, or unregulated.

If no SDS is available, request reliable classification information from the manufacturer or supplier. PHMSA explains that the Hazardous Materials Regulations do not require a shipper to obtain or retain an SDS, but classification remains the shipper's responsibility. Marketplace approval or a generated shipping label cannot replace that determination. When a fulfillment company prepares shipments, establish who performs each regulated function; multiple parties can have responsibilities.

What limited quantity means for your box

Limited quantity, or LQ, provides specified relief when an eligible hazardous material is prepared within prescribed quantity and packaging conditions. Eligibility begins with the applicable transportation entry and exception. Being a small seller or shipping a household product does not establish eligibility.

For bottled liquids, the inner packaging is the bottle directly holding the liquid, including its closure. The outer packaging is the shipping box holding those bottles. The completed package includes the contents, bottles, retail cartons, cushioning, shipping box, and tape. A retail "unit" is a sales description; it might contain one bottle or several. Check the actual containers rather than the number of units on the invoice.

These are selected examples for ordinary U.S. ground combination packages, not a complete list of LQ-eligible materials. Other classes have their own provisions. Use the listed section only when authorized for the material's Hazardous Materials Table entry.

Selected limited quantity limits for ordinary U.S. ground combination packages (49 CFR). Air and vessel shipments use different limits.

One liter is approximately 33.8 U.S. fluid ounces; 30 kg is approximately 66 pounds. These limits require suitable strong outer packaging and the remaining applicable conditions. Class 8 Packing Group I corrosives cannot use the LQ exception in §173.154(b).

For the listed aerosols, check container capacity, design, pressure, and testing information. The ounces printed on a dry-shampoo can may describe product weight rather than container capacity. Aerosols have no packing group, so bottled-liquid packing group limits do not apply to them.

Consider a hypothetical Class 3, Packing Group II perfume in ten 100 mL bottles. Each bottle is below the ground one-liter inner limit. Suppose each filled bottle weighs 0.25 kg: ten weigh 2.50 kg. Add 0.30 kg of retail cartons, 0.40 kg of cushioning, and 0.50 kg for the shipping box and tape. The completed package weighs 3.70 kg. These illustrative weights show the calculation; weigh your actual finished package.

The bottles and box meet the illustrated size and weight limits, but closures, cushioning, compatibility, markings, and other applicable conditions still need checking. A small bottle in an unsuitable box does not qualify merely because it is light.

The 30 kg limit in these examples applies to each completed package, not the truck's combined load. Five separately compliant boxes weighing 20 kg each can remain LQ even though their combined weight is 100 kg. Palletizing them raises separate overpack and marking considerations. Specialized exceptions in §173.156 can change certain packaging or weight conditions; do not assume they apply to an ordinary customer order.

LQ also retains applicable employee training requirements. PHMSA registration is a separate threshold-based obligation under §107.601, not an automatic requirement for every LQ seller. Review the business's actual shipping activities rather than treating training and registration as interchangeable.

Ground, air, and vessel require different checks

For ground shipments, use the applicable domestic exception, packaging conditions, and LQ marking. Qualifying common liquid and aerosol shipments receive substantial relief, although hazardous substances, hazardous waste, and marine pollutants can change documentation requirements.

Air has additional restrictions. Under the domestic air LQ table in §173.27(f), an eligible Class 3, Packing Group II liquid without subsidiary risk is limited to 0.5 L per inner packaging and 1 L net per outer package. Our ten 100 mL bottles total 1 L; twelve would total 1.2 L and exceed that particular outer limit even if the box weighed far below 30 kg. Additional pressure, closure, package-performance, labeling, documentation, and Y-mark requirements apply. Check the exact entry and, where used, ICAO/IATA provisions and airline variations before booking.

For vessel shipments, use the applicable IMDG Code entry and Chapter 3.4 conditions. Do not use the ground table above as an ocean packing instruction. Confirm eligibility, inner limits, completed-package weight, marks, transport documentation, and cargo transport unit requirements with the person preparing the shipment.

An importer bringing 946 mL cans of solvent cement from China to the United States should obtain the confirmed classification and package configuration, then have the ocean preparation and onward U.S. movement reviewed together. A can's volume alone cannot establish compliance. Under §§171.22 and 171.25, authorized IMDG preparation can continue into associated U.S. highway or rail transportation, subject to applicable U.S. conditions.

The emergency-number distinction remains: §172.604(d)(1) provides relief for properly offered LQ shipments without limiting that relief to ground. Air or vessel shipping papers may still be required. For fully regulated imports, applicable U.S. emergency information requirements must be addressed; §171.25(d)(2) contains narrow vessel-transfer exceptions, not a general exemption for goods arriving from overseas. Foreign requirements and carrier policies also need checking.

When the number is required

If LQ does not fit, check other material-specific exceptions before preparing the shipment under the ordinary requirements. Lithium batteries, for example, have separate provisions in §173.185. They should not be treated as ordinary LQ merchandise.

Where no exception provides relief, prepare the material using its applicable packaging, marking, labeling, documentation, and emergency information requirements. Arrange the required telephone coverage before offering it for transportation. A phone service does not approve the shipment's classification or packaging.

The required number must be monitored throughout transportation, including incidental storage, and connect callers to knowledgeable assistance with comprehensive emergency information or immediate access to it. An arrangement requiring a callback is insufficient (§172.604).

A cellphone can qualify, as PHMSA explains in Interpretation 15-0108, but someone must actually maintain the required availability and knowledge. An owner's voicemail or a customer-service desk that closes overnight cannot provide that coverage.

Coverage can be provided internally or through an emergency information provider. A contracted provider must accept responsibility and receive current material information before shipment. Identify the registered customer on the shipping paper as required, using its name or assigned identifier.

Check an SDS contact before adopting it for transport. OSHA does not universally require 24-hour staffing when the SDS specifies contact-hour restrictions. A DOT-required number must meet the transportation standard regardless of those SDS hours.

Optional coverage can also help with LQ incidents by giving callers access to product information. Confirm whether the arrangement covers transportation, customer-use questions, or coordination with additional resources. It supplements emergency services; an active fire or immediate threat to life requires emergency services.

Quick recap

Establish the exact product classification, then check the exception for the intended mode. Measure each inner container and the completed package, and satisfy the remaining preparation requirements. If LQ applies, the DOT emergency-number exception applies; if it does not, check other exceptions and arrange the number wherever required.

Confirm acceptance with the selected UPS, FedEx, USPS, airline, or ocean service before tendering the shipment. Keep the classification and packaging basis traceable, and repeat the review when the product, container, route, or service changes.

Hazmat Compliance & Safety Update: 2025 Year in Review | Hazmat Line

Hazmat Line — Fri, 13 Nov 2026 16:46:32 GMT

The following highlights summarize the most important U.S. and international changes that every hazmat professional should know heading into 2026.

USA Regulatory Updates

PHMSA’s New Data-Driven Enforcement Strategy

On November 20, 2024, PHMSA issued a landmark memorandum outlining its inspection and enforcement priorities for the coming year. Moving away from random inspections, the agency is shifting toward a "data-driven" approach, utilizing advanced analytics to identify high-risk shippers and undeclared shipments before they cause incidents. The memo explicitly highlights a focus on repeat offenders ("recidivism") and packaging integrity, signaling that companies with gaps in their data or prior violations can expect heightened scrutiny in 2025. Read the full memo here: PHMSA Hazardous Materials Enforcement Priorities Memo (Official PDF).

PHMSA — Package of 17 NPRMs (HMR Modernization)

PHMSA published a large set of proposed rulemakings intended to modernize and reduce burdens in the Hazardous Materials Regulations; shippers should scan these NPRMs for positive impacts on special permits, packaging, and paperwork reduction. This "deregulatory" package is a rare opportunity for industry to support rules that lower costs without compromising safety. View the proposals on the PHMSA Rulemakings & Notices (Federal Register) page.

PHMSA — Emergency Response Guidebook (ERG) 2024 Availability

The 2024 ERG and mobile app were released for first responders — make sure your incident plans and driver route packets reference the current ERG guidance. Access the resources on the PHMSA Emergency Response Guidebook (ERG) 2024 page.

PHMSA - Registration Fee Update

Budgeting for compliance may get easier—at least for now. PHMSA has withdrawn its proposed rulemaking that would have increased the annual Hazardous Materials Registration fees for persons who transport, or offer for transportation, certain categories and quantities of hazardous materials. While this temporarily preserves current flat-rate fees for both small businesses and large registrants, it’s still a good time to review your registrations and stay prepared for any future updates. Review the official Hazmat Registration Process overview here.

EPA TSCA: The Sleeping Giant of Compliance

While DOT rules grab headlines, the EPA’s Toxic Substances Control Act (TSCA) is generating significant risk for chemical distributors in 2025. With aggressive new bans on solvents like Trichloroethylene (TCE) and stricter "Significant New Use Rules" (SNURs), hazmat shippers must ensure their products are not just safe to transport, but legal to sell and use at the destination. Find more details in the EPA’s Risk Management & TSCA Implementation update.

OSHA Hazard Communication: Still the #1 Violation

Despite being a mature regulation, OSHA’s Hazard Communication Standard remains a top source of fines. In 2025, inspectors are zeroing in on the accuracy of Safety Data Sheets (SDS) and the "downstream" training of employees. It is no longer enough to just have an SDS; the data must match the label, and the employees must understand the specific hazards, or companies face maximum penalties per violation. Consult the OSHA Enforcement: Hazard Communication Trends report.

International & Standards

IATA / ICAO — Updated Lithium Battery Guidance

IATA published updated guidance tied to the 66th Edition and ICAO Technical Instructions that clarifies handling of newer battery chemistries, cargo tracking devices, and common air-transport questions. If you ship batteries by air, this is mandatory reading to navigate the complexities of the new year. Review the IATA Lithium Battery Guidance Document – 2025.

GHS Revision 11: Recognizing "Global Warming Potential"

The Globally Harmonized System (GHS) continues to evolve, with Revision 11 introducing a new hazard class for chemicals that contribute to global warming. While US adoption often lags behind the UN release, global shippers need to prepare for these changes now. This revision also emphasizes non-animal testing methods for skin sensitization, reflecting a modernization of hazard classification that will eventually impact Safety Data Sheets (SDS) worldwide.

A Step-by-Step Guide to Shipping Hazardous Materials | Hazmat Line

Allan Gotsis — Fri, 13 Nov 2026 16:46:29 GMT

Hazardous materials incidents can have serious consequences—not only for the environment, health, properties and surrounding communities but also for your organization’s reputation and legal liability.

In the U.S., shippers are responsible for properly classifying and packaging hazardous materials, as well as preparing essential documentation before shipment. Below is a step-by-step guide to help you navigate the hazmat shipping process efficiently and in compliance with regulations.

Step 1: Invest in Training and Certification

Anyone involved in handling, packaging, or transporting hazardous materials— including transport and warehouse personnel—must complete HAZMAT training within 90 days of employment or a job function change. Additionally, they must undergo refresher training every three years to remain compliant with DOT regulations.

The Department of Transportation (DOT) offers training programs through its Office of Hazardous Materials Safety (OHMS):

DOT Hazardous Materials Training Programs

Step 2: Classify the Hazardous Material

Proper classification is crucial for compliance and safety. To classify a hazardous material, follow these steps:

1. Check for an Updated Safety Data Sheet (SDS) SDS Overview

2. Identify Key Classification Information, such as

• Four-digit ID number

• Proper shipping name

• Hazard class

• Packing group

3. Verify Classification in the Hazardous Materials Table Hazardous Materials Table

Since proper classification determines packaging, marking, labeling, and shipping paper requirements, accuracy is critical. Additionally, your SDS must include emergency contact information in compliance with regulations. HAZMAT Line can assist by providing 24-hour emergency response phone services and SDS review.

Step 3: Prepare the Packaging

Hazmat packaging must meet strict regulatory requirements based on the material being shipped. Common types include:

• Single packaging (e.g., pails, drums, kegs)

• Combination packaging (inner packages secured within an outer package)

• Composite packaging (integrated layers that cannot be separated)

Since shippers are responsible for proper packaging, ensure compliance with DOT’s performance packaging codes:

DOT Packaging Guide

Step 4: Label Your Package

Hazmat packages must display specific labels and markings, such as:

• Orientation arrows

• Shipper’s information

• Identification number and proper shipping name

• Hazard class labels

For a full breakdown of labeling and hazard communication requirements, refer to:

Hazard Communication Requirements

Step 5: Prepare the Shipping Paper

The shipping paper must contain key information, including:

• Hazmat description

• UN identification number

• Proper shipping name

• Hazard class

• Packing group

• Quantity and type of packages

• Emergency response contact information

• Shipper’s certification

Additional documentation may be required depending on the specific material being transported.

Step 6: Select a Carrier and Provide Emergency Response Information

Before handing off your shipment, coordinate with your carrier to confirm any additional requirements. The shipper must provide a 24-hour emergency response phone service compliant with DOT regulations. DOT regulation 49 CFR 172.604

By following these steps, your organization can improve compliance, mitigate risks, and streamline the hazmat shipping process. Need a 24-hour emergency response phone support? HAZMAT Line is here to help you!

Step 7: Use Preliminary Screening Tools and Product-Specific Resources

The six steps above are the compliance backbone of any hazmat shipment. But especially for e-commerce and small-parcel sellers — who often ship regulated products like perfume, aerosols, cleaning chemicals, or lithium batteries without a dedicated compliance team — a smart first move is to screen the shipment before committing to a classification or a carrier.

CanWeShip is one free, educational resource worth knowing. It's a browser-based, rule-driven pre-checker for U.S. domestic shipments: you answer a few product-specific questions — for batteries, the configuration, chemistry, watt-hours, and condition; for regulated liquids, the SDS and flash-point details — and it evaluates those facts separately against the current USPS, UPS, and FedEx rule sets, then shows each carrier's preliminary status, applicable requirements, warnings, and clearest next step. Its battery route finder is particularly useful for lithium-battery sellers, and it flags damaged, defective, swollen, or recalled batteries that need special handling. CanWeShip also publishes plain-language guides covering flammable liquids and cosmetics, aerosols and pressurized products, and household chemicals and coatings.

One important caveat — one CanWeShip states clearly itself: these tools are preliminary, educational screens, not carrier approval and not a substitute for formal hazmat classification or professional compliance advice. Use them to orient yourself early and avoid obvious dead ends, then confirm the details against the Hazardous Materials Table, each carrier's published requirements, and, where needed, a qualified hazmat professional.

Making Good Choices in HAZMAT Response: When Industrial Hygienists Are Essential | Hazmat Line

Bernard L. Fontaine, Jr. — Fri, 13 Nov 2026 16:46:26 GMT

Introduction

Hazardous materials (HAZMAT) incidents—including chemical fires, industrial explosions, pipeline releases, and transportation accidents—require rapid, high-consequence decision-making under conditions of uncertainty. Incident commanders, emergency managers, firefighters, and HAZMAT technicians are trained to control hazards, stabilize scenes, and protect life and property. However, protecting responder and public health requires more than tactical control; it requires informed evaluation of exposure risk.

Industrial hygienists (IHs) bring expertise in exposure science, toxicology, and occupational health that directly supports these decisions. Their role is not to replace command authority or operational control, but to inform them. Good choices in HAZMAT response are not defined solely by stopping a release or extinguishing a fire—they are defined by whether unnecessary exposures are prevented, health risks are recognized early, and long-term consequences are minimized. This is where industrial hygiene becomes essential.

Keywords: Hazardous materials, emergency response, industrial hygiene, exposure assessment, air monitoring, PPE, ICS

Where Industrial Hygienists Fit in the Response Lifecycle

IHs are most effective when integrated across the full hazard lifecycle—before, during, and after an incident. Extensive industrial facilities, utilities, refineries, laboratories, and research institutions often employ IHs in-house or through either corporate or consulting safety and health functions. In these organizations, IHs are routinely involved in pre-incident activities such as hazard identification, exposure risk assessments, SDS development and interpretation, emergency response planning, training, and pre-incident air monitoring strategies.

During an incident, IHs support Incident Command or Unified Command by evaluating potential and actual exposures, recommending air monitoring strategies, interpreting data, advising on PPE selection, and anticipating secondary or evolving hazards. After the emergency phase, IHs play a critical role in re-entry decisions, contamination assessment, cleanup oversight, exposure documentation, medical surveillance support, and after-action reviews. This continuity helps bridge preparedness, response, and recovery - an often-missing link in emergency management.

HAZMAT Incidents Are Exposure Incidents

Every HAZMAT incident is fundamentally an exposure scenario. Fires, explosions, and releases rarely involve a single, well-defined substance. Responders and nearby communities may be exposed to complex mixtures of gases, vapors, particulates, and combustion byproducts. Heat and fire frequently transform materials into new hazards, including carbon monoxide, hydrogen cyanide, metal fumes, respirable crystalline silica, and polycyclic aromatic hydrocarbons.

Placards, shipping papers, and odor recognition are insufficient for managing these risks. IHs are trained to anticipate what is likely present—even when it cannot be immediately identified or measured—and to guide protective decisions using toxicological principles rather than assumptions. OSHA’s HAZWOPER standard explicitly recognizes this uncertainty, emphasizing that emergency response must address both known and potential hazards, including those generated by fire and decomposition (29 CFR 1910.120).

The Value of Industrial Hygienists in Early Decision-Making

The earliest decisions at a HAZMAT scene often have the most significant impact on health. Isolation distances, evacuation or shelter-in-place orders, PPE selection, and approach strategies all influence exposure outcomes. IHs provide essential input when materials are burning or reacting, multiple or unknown substances are involved, responders face inhalation or dermal risks, or conditions are rapidly changing due to weather or fire behavior.

Common pitfalls—such as underestimating the effects of combustion products, prematurely downgrading respiratory protection, or declaring areas safe based on limited data—are often the result of incomplete exposure evaluation rather than poor intent. Industrial hygiene expertise helps Incident Command make defensible, health-protective decisions under uncertainty.

An on-call IH from the company’s corporate OEHS team was brought into the incident command structure within the first hour. The IH reviewed process chemistry and recent maintenance change, identified the most credible release candidates based on temperature, pressure, and odor threshold, and distinguished between acute irritants and systemic toxicants. Using a photoionization detector (PID), the IH prevented overinterpretation of high total VOC values and avoided escalation based solely on screening data.

The IH’s training and experience applied exposure banding principles to select appropriate respiratory protection while avoiding the use of Level A suits, which would have increased heat stress and slowed the response time. Additionally, the IH defined safe re-entry criteria using conservative occupational exposure limits, established air-monitoring checkpoints and decision thresholds, and enabled controlled, limited entry rather than a blind shutdown.

Accessing Industrial Hygiene Expertise in Smaller Organizations

Many small and mid-sized organizations, including municipal fire departments and smaller industrial operations, do not employ full-time Industrial Hygienists. In these cases, IH expertise is typically accessed through regional consultants, emergency response contractors, environmental firms, insurers, corporate mutual-aid agreements, or public-sector resources.

The challenge is rarely availability—it is timing. Organizations that pre-identify IH resources and integrate them into emergency response plans are far more likely to receive timely, actionable support during an incident. Without planning, IH involvement often occurs after critical decisions have already been made or exposures have occurred. For emergency managers and safety professionals, planning for access to IH expertise is a practical component of preparedness, not an optional enhancement.

Small companies face the same HAZMAT risks as large organizations but usually without dedicated OEHS staff, emergency response teams, or on-site industrial hygienists. The goal is not to become experts overnight, but to know what resources to use, when to use them, and how to make defensible decisions under pressure. Small companies do not need a full-time IH, but they should pre-identify access to one. Here are a few suggestions to obtain the proper support by hiring a part-time or retainer-based consultant. An insurance workers’ compensation carrier can provide loss-control or IH services as part of the policy or a request for additional support. Good decisions in emergencies depend on relationships built in advance.

Air Monitoring Requires Interpretation, Not Just Instruments

Air monitoring is central to modern HAZMAT response, but instruments alone do not define risk. Real-time monitors have limitations, including cross-sensitivities, detection thresholds, and blind spots for specific compounds. “Non-detect” does not necessarily mean “no hazard.”

IHs help select appropriate environmental air monitoring strategies, interpret ambiguous or conflicting readings, recognize instrument limitations, and translate data into operational guidance. OSHA and NFPA emphasize that air monitoring results are interpreted appropriately to support protective decisions. Without this specialized expertise, data can provide false reassurance—or drive unnecessary risk-taking.

Industrial Hygienists in Real-Time Emergency Operations

During active incidents, IHs operate under the same constraints as other responders: incomplete data, time pressure, and rapidly changing conditions. Their value lies in informed judgment and professional experience rather than perfect measurement. IHs assist Incident Command by applying toxicology, exposure modeling, and conservative assumptions when uncertainty is high.

In real-time, IHs advise on sampling locations, likely undetected hazards, PPE selection and downgrade timing, and how fire and explosive behavior, suppression activities, or weather may alter exposure pathways. Equally important, they help communicate uncertainty—clarifying when decisions are precautionary rather than definitive—so that responders understand both the risk and the rationale.

Emergency response phone services are often the first point of contact for experts during a hazardous materials incident. Callers are under stress, information is incomplete, and decisions must be made quickly. This is where IHs add critical value either by telephone or onsite. Rather than replacing emergency response specialists, IHs strengthen and support the decision-making process by translating exposure science into clear, actionable guidance.

For example, a plant supervisor calls an emergency response phone service to report a strong chemical odor, eye and throat irritation among workers, or a spill involving an unfamiliar intermediate chemical. The IH on the phone gathers initial facts, such as the route of exposure, symptoms, and what is known about volatility, odor threshold, and acute toxicity.

The IH can inform the emergency responder about what the instrumentation can and cannot tell us about VOC readings, and how odor perception can occur well below harmful concentrations.

The IH helps the emergency responder communicate measured caution, not panic. IHs can apply exposure banding logic, compare reported conditions to occupational exposure limits, and balance chemical risk against heat stress and physical hazards. They can establish safe re-entry criteria, define monitoring checkpoints, identify when ventilation or isolation is sufficient, and determine when operations can safely resume. This allows the IH to guide the caller through controlled, defensible decisions rather than all-or-nothing actions. Together, they provide credible, calm, and scientifically grounded guidance at the exact moment it is needed most.
When emergency response phone services integrate IH expertise, worker and responder exposures are reduced, unnecessary evacuations are avoided, downtime is minimized, regulatory compliance decisions are more defensible, and trust with authorities and the community is preserved. In many cases, the cost of the call is trivial compared to the losses avoided.

Fire, Re-Entry, and Long-Term Health Protection

When fires are controlled and visible hazards are gone, health risks often remain. Combustion byproducts, settled particulates, contaminated debris, and off-gassing materials can pose ongoing exposure risks during overhaul, cleanup, and re-entry. IHs are essential for evaluating these conditions, establishing clearance criteria, documenting exposures, and supporting long-term health surveillance.

Delayed occupational and public health effects—including respiratory disease, cancer, and cardiovascular impacts—underscore the importance of documenting exposure and conducting follow-up. IHs help ensure that response decisions protect not only today’s responders, but also their long-term health.

Conclusion

Effective HAZMAT response depends on informed decision-making grounded in exposure science. IHs are essential team members whenever health risks must be evaluated—not just when immediate hazards are controlled.
• Firefighters suppress hazards.
• HAZMAT teams contain releases.
• IHs protect health—during incidents and long after they end.

Integrating IH expertise into emergency management and incident response leads to better and more informed decisions, safer work tasks for responders, healthier communities, and stronger recovery outcomes. In HAZMAT response, that contribution is essential—not optional.

What Travels with the Battery | Hazmat Line & EV Fire

Hazmat Line and EV Fire Company — Fri, 13 Nov 2026 16:46:22 GMT

By the time the fire is out and the road is reopening, everyone wants the incident to be over. With a compromised electric vehicle (EV) or e-mobility battery, that is often the point where the risk starts moving to someone else.

But the battery is still going somewhere — and so is everything responders learned about it.

The vehicle may be loaded onto a flatbed. The battery may end up at a tow yard, insurer, municipal storage site, recycler, or disposal stream. What matters is not only where it goes. It is what information goes with it.

As battery-response knowledge evolves, so must the information surrounding an incident: what responders carry in written guidance, what is asked during the emergency call, and what is passed forward into towing, storage, monitoring, and the next stage of custody.

If the condition history does not travel with the battery, the next person in the chain may be managing a hazard they were never properly told about.

1. What Responders Are Learning

Electric vehicle and lithium-ion battery fire guidance is improving, but the practical gap is often what happens after the visible fire is controlled. Fire crews are getting better information on suppression, cooling, high-voltage hazards, and manufacturer emergency response guides. That matters, but it does not answer every operational question once the vehicle is ready to leave the scene.

Recent full-scale work from the UL Fire Safety Research Institute (UL FSRI) has been useful because it tests some of the assumptions that show up on the fireground. A visible flame can be knocked down while the battery pack still has to be treated with caution. Water remains the best cooling agent, but that does not mean every water application is equally useful. If water cannot reach the cells that are actually involved, crews may be using large volumes without changing what is happening inside the pack. At the same time, that water can create a runoff problem that now has to be managed.

Fire blankets are another example. They can have a role, especially for exposure protection, loading or transport risk reduction, or situations where water access or runoff control is a major constraint. But they are not a magic fix. A blanket does not stop thermal runaway inside the pack, and it can create its own hazards if flammable gases continue to accumulate underneath it and are later exposed to air during lifting, disturbance, or removal. That concern is even greater indoors or in confined spaces, but it is not limited to those settings. If an organization is going to use blankets, the written standard operating procedure matters more than the equipment. Crews need to know when to deploy one, when not to, how to monitor for gas accumulation or renewed battery activity, and how to manage the blanket without creating a bigger problem during disturbance or removal.

The current Emergency Response Guidebook (ERG) lithium battery and EV fire language is a starting point, not a complete operating model. We understand the ERG is built for the initial phase of a dangerous goods transportation incident and cannot become a full tactical manual. But EV Fire Company has raised concerns with CANUTEC / Transport Canada that the existing EV/lithium battery section should be refined as current research and field experience continue to develop. Responders need clearer practical cues around battery condition, uncertainty, water application, fire blanket limitations, runoff, movement, isolation, monitoring, and handoff.

The field reality is that apparent knockdown is not the same as battery stability. A battery may be fire-involved, heat-exposed, mechanically damaged, submerged, venting, leaking, or simply uncertain. Those distinctions matter because the next person in the chain may be a tow operator, storage yard, insurer, environmental contractor, recycler, or municipal authority. "Unknown" should not quietly become "safe" just because the scene is being released. If the uncertainty is captured and passed forward, the next custodian can manage it. If it is not captured, the system is guessing.

As guidance evolves, the question is not only how the active fire is handled. It is what condition the battery is in when responsibility changes hands, and what the next party needs to know.

2. What Risk Travels with the Battery

EV Fire Company uses three simple questions before a compromised EV or e-mobility battery is released from the original response scene:

How was the battery classified?
Was it involved in fire, exposed to heat, damaged in a collision, submerged, leaking, venting, or unable to be assessed with confidence?

What risk travels with it?
What is the thermal history, visible or audible battery behavior, runoff concern, smoke or vapor exposure, personal protective equipment and decontamination concerns, and remaining uncertainty?

Who owns the next control phase?
Is the tow operator prepared? Can the receiving site isolate and monitor it? Who accepts custody, and what controls are expected after transfer?

Those are not paperwork questions. They are risk-control questions. The handoff is the point where an incident can either stay controlled or become someone else's surprise.

A vehicle that has been involved in an EV battery incident may look quiet during loading. That does not mean the history no longer matters. A tow yard or storage site may never see the original smoke, heat, runoff, odor, popping, hissing, pack intrusion, or uncertainty. If those details are not captured while people still remember them, they are often gone for good.

The goal is not to overcomplicate every vehicle fire. The goal is to preserve the facts that could change the next decision. If the battery was never involved, say that. If involvement is uncertain, say that too. Uncertainty is not a weakness in the record. It is one of the things the next custodian needs to know.

These questions highlight something important. A battery incident is not only a fireground problem. It can become a custody problem. Every transfer creates another opportunity for important information to disappear.

3. Where the Emergency Call Fits

Hazardous-material emergency response is rarely a one-way exchange. During an incident call, the emergency-response information provider is gathering information from the scene while also providing information back to the people managing it. With lithium-ion batteries, that exchange becomes especially important because the product may be identifiable while the condition of a specific battery or package is changing.

The call begins with familiar fundamentals: Who is calling? Where is the incident? What happened? Is anyone injured or exposed? Is there fire, smoke, vapor, heat, or another immediate concern? What product or battery is involved, and what shipping papers, Safety Data Sheet (SDS), manufacturer information, or other resources are available? From there, the questions can become more battery-specific. The goal is not to diagnose the battery remotely, but to build the best available picture of the incident and provide relevant emergency-response information back to the scene.

A simplified call might sound something like this:

Caller:"We have a damaged package containing a lithium-ion battery for a robotic inspection unit. The carton was crushed during handling. Part of the battery housing is visible and appears deformed, the package feels hot, and employees reported hissing and white vapor coming from the box."

Emergency-response specialist:"Is anyone injured or exposed? Is the package still producing heat, vapor, smoke, odor, hissing, popping, or other signs of battery activity?"

Caller:"One employee was standing nearby when it started venting, but there was no direct contact. The area has been cleared, the fire department is on scene, and the package has been isolated from the other freight."

Emergency-response specialist:"Do you have the shipping information, battery identification, SDS, or manufacturer information available? Has the package been moved or opened, and have responders reported temperature readings or changes in condition?"

Caller:"The package has not been opened. We have the shipping paperwork and can get the product information from our shipping department. Responders are monitoring it and are asking for more information about the battery and the hazards associated with the shipment."

Emergency-response specialist:"Can you confirm the UN number and proper shipping name from the shipping paperwork?"

Caller:"The shipping paper shows UN 3480, lithium ion batteries."

Emergency-response specialist:"Thank you. And do you have the manufacturer name or product name for the battery itself?"

Caller:"Yes, it's listed on the paperwork — I can read that to you now."

With the UN number, proper shipping name, and product identification confirmed, the emergency-response specialist locates the Safety Data Sheet for the battery and begins pulling relevant hazard and response information to share with the caller and responding personnel.

Emergency-response specialist: "Based on the SDS and the information you've provided, here is what the responding personnel should be aware of regarding the hazards associated with this battery and this incident…"

After passing the relevant information to the caller:

Emergency-response specialist:"I will document everything reported — the damaged packaging, the deformation, the heat, the hissing, and the white vapor, the employee in the vicinity, and the current status as responders are monitoring on scene. I will also notify the shipper and responsible party so they are aware this incident has occurred. As this situation evolves, it is important to keep monitoring the condition of the battery — understanding its hazard profile doesn't stop when the visible activity slows down. A damaged lithium-ion battery remains a risk through recovery, transport, and disposal, and everyone who handles it from this point forward needs to be aware of that."

Once the initial facts are established, the specialist reviews the available SDS, shipping information, manufacturer guidance, and other applicable emergency-response resources. Relevant information is communicated based on conditions at the scene, while new observations are documented as the incident develops.

This is the two-way role of the emergency-response telephone service. The facility and responders provide real-time observations that a reference document cannot supply, while the shipper may provide battery specifications or product information that was not initially available. Hazmat Line connects those pieces with the technical information on hand and maintains a record of what was reported and when.

The next person handling that battery may never have spoken with the original caller or witnessed the heat, vapor, physical damage, response actions, exposure concerns, or uncertainty at the scene. For everyone who touches it afterward, the record of what happened — and what wasn't yet known — may be the most important safety tool they have.

Hazmat Line has developed a battery program that adapts its incident reporting process to capture the details of that exchange. A battery-specific section of the incident report documents the nature of the event, observed battery and package condition, heat or fire involvement, smoke or vapor, physical damage, leakage, exposure concerns, control measures, and other relevant observations. It can also preserve what remains unknown, rather than allowing uncertainty to become an assumption.

After the immediate emergency, Hazmat Line will follow up with the shipper to gather any information that was not available during the call — additional battery or shipment details, updated incident information, photographs or documentation when appropriate, and clarification about how the package, battery, or equipment was ultimately handled. All of that is documented and compiled into a report that is sent back to the shipper. As the damaged battery moves from hand to hand, that report travels with it — giving everyone who touches it afterward a clear picture of what happened, what was observed, and what was done.

The incident doesn't end when the call does. In that way, the emergency-response telephone service can do more than answer the initial call: it can gather critical information from the ground, pass relevant guidance back to those managing the incident, and preserve the resulting history so it can move forward when needed.

4. What Should Actually Travel with the Battery?

Not every responder, tow operator, storage facility, insurer, investigator, recycler, or environmental professional needs the same level of technical detail. But the next custodian does need enough information to understand what they are accepting.

EV Fire Company would not expect a fire crew or call center to produce a battery-engineering report at the side of the road. That is not realistic. What is realistic is a short condition-history package that can travel with the vehicle or battery.

At minimum, that handoff should capture:

Incident type: fire, collision, submersion, charging incident, e-mobility device incident, thermal event, or unknown.
Battery condition: no visible involvement, exposed to heat, suspected involvement, confirmed involvement, active venting or off-gassing, leaking, physically damaged, or unable to assess.
Thermal history:last temperature check, trend if known, tool used, time since last abnormal heat, and whether heat was localized or increasing.
Visible or audible cues: white or grey vapor, smoke, odor, popping, hissing, jetting, flame from the pack area, electrolyte leakage, or deformation.
Suppression and control actions: water applied, where it was applied, whether a blanket or other control was used, and whether runoff or storm drains were involved.
Exposure and contamination concerns:smoke or vapor exposure, contaminated personal protective equipment or tools, runoff contact, public exposure, and whether decontamination or medical advice was considered.
Movement controls: flatbed or other method, loading concerns, route or escort considerations, no indoor storage expectations, and whether the receiving site was briefed before movement.
Storage and monitoring expectation:isolation distance or separation method, access control, thermal monitoring expectation, recheck interval if set, and release criteria if known.
Custody:who accepted the vehicle or battery, when they accepted it, and what condition information they received.

This does not make the incident perfect. It makes the risk visible. That is the difference between an informed handoff and a blind transfer.

For the emergency-response information provider, the challenge is to capture those facts reliably and preserve them in a form that remains useful after the call ends — not to create a second technical report, but to keep condition history from disappearing during the handoff.

5. The Feedback Loop

Better incident information has value beyond one call. Over time, it can reveal where details are repeatedly missing, where handoffs break down, and which battery conditions are difficult to characterize. That feedback loop matters: research improves guidance, field experience improves the questions being asked, and better records show where guidance and practice still need work.

That raises a broader question for emergency-response telephone services: as lithium battery incidents become better understood, how can the service better support every stakeholder who may encounter the incident?

The shipper may need help organizing battery information before transportation. Carriers and responders need accurate information when something goes wrong. Tow operators, storage facilities, insurers, environmental contractors, recyclers, and other downstream parties may need to understand what occurred before they became involved.

An emergency-response telephone service sits between many of those parties. Its value can extend beyond answering the initial call if the information gathered is structured, preserved, and capable of supporting the next stage of the incident.

As the industry continues to learn, emergency-call intake should evolve with it. Better questions create better records, better records create better handoffs, and better handoffs give the next stakeholder a better opportunity to understand the risk they are inheriting.

When the battery moves, the information needed to manage the risk needs to move with it.

The 9 Classes of Hazardous Materials Guide | Hazmat Line

Allan Gotsis — Fri, 13 Nov 2026 16:46:19 GMT

In Brazil, every hazardous product must be classified into one of nine internationally standardized classes before transport. These classes follow the "Orange Book," UN Model Regulations, which was created with the purpose of standardizing hazardous materials transport rules worldwide. Brazil's ANTT Resolution 5.998/22 adopts this international system and establishes how products must be packaged, labeled, documented, and handled during road transport.

Critical Distinction: The hazardous materials classification for transport (also referred to as TDG - Transportation of Dangerous Goods from the UN), is NOT the same as the GHS classification (Global Harmonized System, also from the UN). The systems are different because they have different objectives - TDG uses 9 classes focused on the risk each product presents when transported, such as flammable, corrosive, while GHS is broader, covering health, physical and environmental hazards, with a total of 29 classes and subclasses. GHS is used in Section 2 of Safety Data Sheets (SDS, formerly MSDS). This confusion between the two systems is not just a simple mistake, it is a serious error that can constitute a violation of Brazilian law.

GASES

Divided into three subclasses:
2.1 Flammable 2.2 Non-Flammable 2.3 Toxic

FLAMMABLE LIQUIDS

Includes paints, varnishes, thinners, and similar products. Categorized by packing groups (I, II, or III) based on danger level.

FLAMMABLE SOLIDS

Divided into three divisions:
4.1 Flammable solids 4.2 Spontaneously combustible 4.3 Dangerous when wet

OXIDIZING SUBSTANCES & ORGANIC PEROXIDES

Divided into two divisions:
5.1 Oxidizing Substances 5.2 Organic Peroxides

Materials that damage tissue or metals. Special labeling rule: text and numbers appear in WHITE (not black) on labels.

MISCELLANEOUS DANGEROUS GOODS

Products presenting transport hazards not covered by Classes 1-8, including lithium batteries (see our guide to shipping lithium-ion batteries). Must display Class 9 label and proper shipping name.

KEY CLASSIFICATION CONCEPTS

●

Primary Risk The main hazard class of the product

●

Subsidiary Risk(s) Additional hazards requiring extra labels

●

UN Number Four-digit identification code for each product

●

Proper Shipping Name Official transport designation for documentation

PACKING GROUPS (Classes 3, 4, 5, 6, 8)

High Danger

Medium Danger

III

Low Danger

Understanding Subsidiary Risks

Many dangerous products have more than one type of hazard. These hazards are identified through the Risk Number (top section of the orange panel) and appear on package labels:

Primary Risk: The main hazard class (first digit of the risk number)
Subsidiary Risk(s): Additional hazards (second and third digits, when present)

How to Read the Orange Risk Panel

Example 1: Product with Subsidiary Risk

X886

1831

1st digit (X): "Dangerous when wet" - product reacts with water

2nd & 3rd digits (88): Highly corrosive (repeated number = greater intensity)

4th digit (6): Toxic/poisonous (subsidiary risk)

UN 1831 = Sulfuric Acid
Primary Class: 8 (Corrosive)
Subsidiary Risk: 6 (Toxic)

Example 2: Highly Flammable Product

3475

1st digit (3): Flammable liquid

2nd digit (3): Flammable liquid (repeated = highly flammable)

UN 3475 = Gasoline and Ethanol Mixture
Primary Class: 3 (Flammable Liquid)
Subsidiary Risk: None - repeated number indicates high intensity

Example 3: Product WITHOUT Subsidiary Risk

1350

1st digit (4): Flammable solid

2nd digit (0): Zero indicates absence of secondary risk

UN 1350 = Sulfur
Primary Class: 4 (Flammable Solid)
Subsidiary Risk: None

Important Rules About Risk Numbers:

When a number is repeated (e.g., 33, 88), it indicates GREATER intensity of the hazard

When the number is 0 (e.g., 40), it indicates ABSENCE of secondary risk

The letter X at the beginning means the product reacts dangerously with water - DO NOT use water in emergencies!

Class labels must be placed close to each other on the packaging when there are subsidiary risks

GHS, SDS Classification vs. TDG, Transport Classification

What's the Difference?

GHS (Globally Harmonized System) has a broader focus on the chemical product. It evaluates not only hazards during transport, but also other risks related to the use, storage, and safe handling of chemical substances in warehouses, factories, and laboratories. It is the system that guides the preparation of Section 2 of the Safety Data Sheet (SDS, formerly MSDS). Think of it as "what happens inside the factory."

The transport classification, also called TDG (Transportation of Dangerous Goods) is detailed in the Orange Book (UN Model Regulations for the Transport of Dangerous Goods). Its objective is to identify product hazards during movement on highways, railways, airways or waterways. This classification guides emergency responders, carriers, and authorities about the risks that exist during transport. Think of it as "what happens on the road."

Aspect	GHS (ABNT NBR 14725)	Transport (ANTT 5.998/22)
Purpose	Workplace safety - storage & handling	Transport safety - movement on roads/rails/air/sea
Focus	Worker protection during daily use	Public safety & emergency response during transport
Classification basis	Health, physical, and environmental hazards	Risks during transport (fire, explosion, leakage)
Found in	FISPQ/SDS Section 2 (Hazard Identification)	FISPQ/SDS Section 14 (Transport Information), transport documents, labels, placards
Number of classes	Multiple hazard categories	9 main classes
Used for	Day-to-day operations inside facilities	Shipping, emergencies, and regulatory compliance

Practical Example: Acetone

Acetone is a common industrial solvent. Here's how it's classified in BOTH systems:

GHS Classification (Workplace/Storage):

Flammable Liquid - Category 2

Eye Irritation - Category 2A

STOT Single Exposure - Category 3 (narcotic effects)

What this means for workers: Wear safety glasses, use in ventilated areas, avoid prolonged exposure, keep away from heat sources.

Transport Classification (Road Transport):

UN 1090

Proper Shipping Name: ACETONE

Class: 3 (Flammable Liquids)

Packing Group: II (Medium danger)

What this means for transport: Must use approved packaging, display Class 3 labels, carry emergency response information, follow specific routing restrictions.

Why the Same Product Has Different Classifications

The systems evaluate different risks:

GHS looks at what happens when workers handle the product daily - chronic exposure, skin contact, inhalation over time
Transport looks at what happens in an accident - immediate fire risk, explosion potential, environmental damage from a spill

Example: A product might be highly toxic if inhaled daily (important for GHS) but stable during transport (less critical for transport classification). Conversely, a product might be safe for daily use but extremely flammable during transport.

Critical Rule: NEVER use only the GHS classification from your FISPQ/SDS for transport purposes. You must perform a separate transport classification according to ANTT regulations. Both are legally required, and both serve different purposes.

Where to Find Each Classification

GHS Classification: Section 2 of the FISPQ/SDS (Hazard Identification)
Transport Classification: Section 14 of the FISPQ/SDS (Transport Information) - but always verify independently
Emergency Phone Number: Section 1 of the FISPQ/SDS (Identification) - see our guide to SDS emergency phone number requirements

For more information specifically about GHS, access: https://pubchem.ncbi.nlm.nih.gov/ghs/

Classification Steps for Brazil

Evaluate the product's physical, chemical, and toxicological properties

Determine if it's dangerous for transport under Brazilian regulations

If dangerous, identify the primary hazard class (1-9)

Check for subsidiary risks

Consult the official Brazilian List of Dangerous Products

Determine packing group (if applicable)

Document everything for transport documents and labels

Special Cases in Brazil

Empty and Uncleaned Packaging

Except for Class 7 (radioactive), empty packaging that contained dangerous products must be classified and labeled according to what they last contained.

Format: UN 3509 EMPTY PACKAGINGS, UNCLEANED, 9

Limited Quantities

When transporting small quantities that meet limited quantity limits, certain requirements may be exempted. The document must include the notation "QUANT. LTDA".

Waste Products

Add "WASTE" before the shipping name:

Example: UN 1824 WASTE SODIUM HYDROXIDE SOLUTION 8 II

Why Accurate Classification Matters

●

For Emergency Response First responders need correct hazard information immediately (see which hazmat hotline to call)

●

For Compatibility Prevents dangerous reactions between incompatible materials

●

For Legal Compliance Protects against criminal prosecution under Brazil's Environmental Crimes Law

●

For Safety Ensures proper precautions throughout the transport chain

Consequences of Incorrect Classification:

Personal injuries or environmental damage

Criminal liability under Article 56 of Environmental Crimes Law

Immediate fines and cargo detention

Business license suspension

Reputational damage

Required Documentation in Brazil

Classification information must appear in:

✓

The Benefits of Function-Specific Hazardous Materials Training | Hazmat Line

Stars Hazmat Consulting — Fri, 13 Nov 2026 16:46:18 GMT

Handling hazardous materials is an essential part of many industries, including transportation, manufacturing, healthcare, energy, and waste management. Because these materials can pose significant risks to people, property, and the environment, proper training is not just recommended—it is required. One of the most effective approaches to ensuring safety and regulatory compliance is function-specific hazardous materials (hazmat) training.

Function-specific training focuses on the exact tasks an employee performs when handling, preparing, transporting, or managing hazardous materials. Rather than providing only general awareness, it equips workers with the precise knowledge and skills needed to perform their responsibilities safely and legally.

Below are several key benefits of implementing function-specific hazmat training.

Improved Safety for Employees and the Public

Hazardous materials can include flammable liquids, toxic chemicals, corrosive substances, radioactive materials, and more. When handled incorrectly, these materials can cause fires, explosions, chemical exposure, or environmental contamination.

Function-specific training teaches employees:

The specific hazards associated with the materials they handle each and every day
Safe handling and storage procedures
Proper packaging and labeling methods
Emergency response steps in the event of a spill or release

By focusing on the employee’s actual job responsibilities, the training ensures workers understand exactly how to prevent accidents in their daily tasks.

Regulatory Compliance

In the United States, hazmat training requirements are defined by the U.S. Department of Transportation (DOT) under the Hazardous Materials Regulations (49 CFR Parts 171–180).

These regulations require hazmat employees to receive training in several categories, including:

General awareness training
Function-specific training
Safety training
Security awareness training
In-depth security training (when applicable)

Function-specific training is particularly important because it directly addresses the regulatory requirements tied to an employee’s job duties. Organizations that fail to provide proper training may face significant penalties, including fines and operational disruptions.

Providing structured function-specific training helps companies demonstrate compliance during audits, inspections, or incident investigations.

Reduced Risk of Costly Incidents

Hazmat incidents can be extremely expensive. The operational business costs associated with incidents relate to production downtime, cleanup (and remediation, as applicable), and potential equipment damage and personal injury. Additionally, regulatory fines and penalties can be assessed and liability claims for injuries (up to, and including, death) can hamper business operations or even shut down organizations completely.

Many of these incidents occur because of simple procedural errors—such as incorrect packaging, missing labels, or improper documentation.

Function-specific training reduces these risks by ensuring employees understand:

Correct shipping paper preparation
Proper hazard communication
Packaging requirements
Loading and segregation rules

Preventing even one incident can save organizations thousands—or even millions—of dollars.

Increased Employee Confidence and Competence

Employees who are unsure about regulations or procedures are more likely to make mistakes. Function-specific training provides clear, job-focused instruction that helps employees feel confident in their responsibilities.

Workers learn what regulations apply to their role, how to perform the necessary tasks safely and correctly and how to rectify situations when something goes wrong.

This clarity improves job performance, reduces stress, and promotes a culture of safety within the organization.

More Efficient Operations

When employees understand the correct procedures for handling hazardous materials, operations become more efficient.

Function-specific training helps reduce:

Shipping delays caused by incorrect documentation
Rejected shipments due to packaging errors
Time spent correcting regulatory mistakes

Well-trained employees can prepare shipments correctly the first time, improving workflow and customer satisfaction.

Stronger Safety Culture

Organizations that invest in proper training send a clear message: that Safety and Compliance Matter!

Function-specific hazmat training reinforces accountability by ensuring each employee understands their role in maintaining safe operations. Over time, this contributes to a stronger safety culture where employees recognize potential hazards, follow procedures consistently and maybe , most importantly, speak up about safety concerns within the operation.

A strong safety culture not only protects employees but also enhances the company’s reputation with regulators, partners, and customers.

Conclusions

Function-specific hazmat training is a critical component of any hazardous materials safety program. By focusing on the tasks employees actually perform, it provides practical knowledge that improves safety, ensures regulatory compliance, and reduces operational risks.

Organizations that prioritize this targeted training approach benefit from safer workplaces, more confident employees, and more efficient operations. In industries where hazardous materials are part of everyday work, function-specific training is not just a regulatory requirement—it is a vital investment in safety and success.
