Understanding 49 CFR 172.704: Getting Hazardous Materials Training Right

By Michael Burdick

Introduction

Hazardous materials training is one of the most important elements of a safe and compliant transport system. Yet it is also one of the most frequently misunderstood areas of the United States Hazardous Materials Regulations.

This article continues our training series by examining the core requirements of 49 CFR 172.704. Understanding these provisions helps employers ensure that training is matched to an employee’s responsibilities while meeting the regulatory requirements for competence, documentation and ongoing compliance.

General Awareness Training

Section 172.704(a)(1) establishes the requirement for general awareness training for each hazardous materials employee identified by the employer.

Depending on an employee’s role, this training may simply require them to identify and recognise hazardous materials as they relate to their specific duties. Not every employee is required to perform every hazardous materials function, and the training should reflect this.

Function Specific Training

Section 172.704(a)(2)(i) requires each employee to receive training appropriate to the functions they actually perform.

For example, an employee whose sole responsibility is preparing hazardous materials documentation only needs training relevant to that activity. They are not required to receive training in unrelated pre-transportation functions such as packaging, filling or labelling if those tasks are outside their role. Matching training to actual job functions is a fundamental principle of the regulation.

Section 172.704(a)(2)(ii) is an area that often creates confusion within industry. The author notes that this provision will be examined in greater detail in a future article.

Emergency Response Responsibilities

Section 172.704(a)(3) directs employers to the emergency response requirements contained in 49 CFR 172.600.

These requirements must be followed, and employers are expected to have documented policies and procedures that demonstrate how they meet their emergency response obligations. The author notes that this topic will also be explored in greater detail in a future edition, as many organisations do not fully understand the scope of their responsibilities.

Security Awareness Versus Security Plans

One of the most common areas of misunderstanding involves the distinction between security awareness training and a security plan.

Sections 172.704(a)(4) and (5) require every hazardous materials employee to receive security awareness training. Employers should also remember the 90 day training requirement for new employees.

However, organisations offering any of the hazardous materials identified in 49 CFR 172.800 must go further by developing and implementing a formal security plan that includes all elements required by 172.802. That plan must also be available for inspection by authorised government officials.

Recognition of Other Training

Section 172.704(b) recognises that employees may receive training through other government agencies.

While this may satisfy some elements of the hazardous materials training requirements, employers should exercise caution. Other regulatory training programs may only address part of the requirements contained within 49 CFR, meaning additional hazardous materials training may still be necessary to achieve full compliance.

Training Frequency

Section 172.704(c)(1) specifies when training must be completed for new employees and establishes the requirements for recurrent training.

Importantly, new employees may not perform hazardous materials functions unless they are under the direct supervision of a properly trained hazardous materials employee. Direct supervision means active oversight by a qualified individual.

Sections 172.704(c)(2) through (4) also highlight one of the key differences between United States and international regulations. Under 49 CFR, recurrent training is required every three years, whereas IATA and ICAO require recurrent training every two years. Regardless of the interval, responsibility for ensuring training remains current rests with the employer.

Training Records

Section 172.704(d) outlines the information that must be included in an employee’s training record.

While many organisations successfully capture the basic information required under items (d)(1) and (d)(2), the remaining requirements are often overlooked.

Key requirements include:

1. Employers must retain either copies of the training materials used or a detailed description of those materials. Regulators frequently review this information to verify that all required subject areas have been addressed.
2. Training records must include the name and physical address of the person who provided the training. Website addresses and email addresses alone do not satisfy this requirement.
3. Employees must be both trained and tested. Although the regulations do not require employers to retain copies of examination papers, regulators may request to review them. Employees should also be formally certified as having successfully completed both the training and testing process, ideally by the individual who conducted the training.

Limited Exceptions

Section 172.704(e) provides limited exceptions to certain training requirements for applicable employees.

Organisations should carefully review these provisions to determine whether any exceptions apply to their particular operations before assuming training obligations have been reduced.

Final Reflection

Effective hazardous materials training is about far more than satisfying a regulatory requirement. It ensures employees understand the responsibilities associated with their role, supports consistent compliance and contributes directly to safer hazardous materials transport.

Understanding the intent behind 49 CFR 172.704, and applying its requirements correctly, helps organisations build training programs that are both compliant and operationally effective.
