A DOT hazmat employee can be someone who packages, marks, labels, prepares shipping papers for, loads, or otherwise performs regulated hazardous materials transportation functions. The right training depends on the duties the person actually performs, not simply their job title.
At a glance
DOT hazmat employee training includes general awareness and function-specific instruction, plus applicable safety and security components. The employer must match the training to the employee’s duties. Recurrent training is generally required at least every three years.
The required training components
Federal hazardous materials training rules include general awareness and familiarization, function-specific training, safety training, and security awareness. In-depth security training applies when the employer is required to have a security plan. Drivers performing relevant motor-vehicle functions also have driver-related requirements.
General awareness is not the same as function-specific instruction
General awareness introduces the hazard-communication and regulatory system. Function-specific training covers the rules and procedures that apply to an employee’s actual work. A general-awareness course alone should not be assumed to cover shipping papers, packaging, marking, labeling, or other assigned functions.
How often does recurrent training apply?
PHMSA states that hazmat employees must receive appropriate recurrent training at least once every three years. New employees and employees changing hazmat functions generally have 90 days to complete the required instruction, and may perform covered work during that period only under direct supervision of a properly trained and knowledgeable employee.
What the employer needs to keep
A compliant training record generally identifies the employee, completion date, training materials, training provider, and evidence the employee was trained and tested. The employer remains responsible for the adequacy of the training even when an outside company delivers the course.
Five questions before choosing a course
Which transport modes are used? Does the employee package, classify, load, prepare paperwork, or drive? Which training components does the course actually cover? Will the provider issue the documentation your company needs? Have the employee’s functions or governing rules changed since their last training?
Are free resources available?
Yes. PHMSA publishes free hazmat training modules and explanatory material. Paid courses may offer a structured curriculum, testing, or records, but you should compare the scope and documentation before buying. Start with PHMSA’s free training modules.
Related training
DOT hazmat transportation training is different from HAZWOPER hazardous waste site training and from ELDT for a first-time CDL hazardous materials endorsement. One does not automatically replace another.
