What is a hazmat employee?

The definition that decides who has to be trained — read the way a regulator reads it.

The short answer

A hazmat employee is a person employed by a hazmat employer — full-time, part-time or temporary — or a self-employed person, who directly affects hazardous materials transportation safety in the course of employment. The regulation then lists the functions that count. The label is created by the function, not by the contract, the job title, or how often the work happens.

What the definition actually says

49 CFR 171.8 defines the term this way:

Hazmat employee means a person who is employed on a full-time, part time, or temporary basis by a hazmat employer and who in the course of such full time, part time or temporary employment directly affects hazardous materials transportation safety.

49 CFR 171.8 — the section then lists the covered functions and includes a self-employed person performing them. Quoted from the eCFR; read the current text at the link above.

It is built out of four pieces. All four are worth reading separately, because employers usually get caught on the one they skimmed.

PieceWhat it means in practice
Employed by a hazmat employerYour business has to be a hazmat employer first. That means it uses employees in connection with transporting hazardous materials in commerce, causing them to be transported, or representing that a container is qualified for that use.
Full-time, part-time or temporaryAll three, expressly. There is no minimum number of hours and no exemption for seasonal staff.
Or self-employedA self-employed person performing the functions is included, so an owner-operator cannot fall through the gap.
Directly affects transportation safetyThe operative filter. It is what separates the people who need training from the people who merely work nearby.

The covered functions

The definition then enumerates what "directly affects" looks like. A person is a hazmat employee if they:

  • load, unload or handle hazardous materials;
  • design, manufacture, fabricate, inspect, mark, maintain, recondition, repair or test a package, container or packaging component represented as qualified for transporting hazardous materials;
  • prepare hazardous materials for transportation;
  • are responsible for the safety of transporting hazardous materials; or
  • operate a vehicle used to transport hazardous materials.

Note the fourth one. "Responsible for the safety of transporting" catches supervisors, managers and compliance staff who never physically touch a package but whose decisions govern how it moves. It is the clause that most often surprises people.

This page is about what the definition says. For the same test applied to real warehouse, shipping, 3PL and courier jobs — which titles usually fall inside it and which usually do not — see who needs DOT hazmat training.

What a hazmat employee is not

It is not a certification, a licence or a status you hold.

Nobody "is certified as a hazmat employee". It is a description of a person's role under the rule while they perform certain functions for a certain employer. If they change jobs, the new employer owes them the training — training does not travel with the person as a licence would. Certificate versus licence, explained.

It is not decided by your org chart.

Two people with identical titles at the same site can differ: one handles the hazmat SKUs, the other does not. The rule follows the work.

Hazmat employee vs hazmat employer

The two terms are defined separately and carry different duties. 49 CFR 172.702(b) places the duty squarely on the employer: it must train and test each hazmat employee, and certify that it has done so. No training vendor can absorb that duty, and any vendor telling you otherwise is selling you a false sense of security. What a vendor can do — what we do — is deliver the course, test the employee, and hand you a record built to slot into your file. Where our course stops and your duty begins, and the employer's obligation set out item by item.

What follows once someone is a hazmat employee

  1. They must receive the training categories in 172.704(a) that apply to their function.
  2. They must be tested on it — 172.704(c)(1) and (d)(5).
  3. The training must be complete within 90 days of employment or a change in function; until then they may perform the function only under the direct supervision of a trained hazmat employee.
  4. It must be repeated at least every three years.
  5. The employer must create and keep the record in 172.704(d).

Common questions

Is a hazmat employee the same as a hazmat employer?
No, and the difference matters. The hazmat employer is the business that uses employees in connection with transporting hazardous materials; the hazmat employee is the person performing the covered function. 49 CFR 172.702(b) puts the training, testing and certification duty on the employer, not on the employee or on the training vendor.
Can someone be a hazmat employee for only part of the year?
Yes. The definition covers temporary employment. Someone brought in for a peak season who handles hazardous materials is a hazmat employee for that period and needs training before performing the function unsupervised.
If we only ship hazardous materials occasionally, is anyone a hazmat employee?
Frequency is not part of the definition. If a person performs a covered function at all, they are a hazmat employee. An operation that ships hazmat twice a year still has hazmat employees on those days — and they must have been trained beforehand.
Does a job title decide it?
No. 49 CFR 171.8 turns on the function performed, not on the title on the org chart. Two people with the same title at the same site can differ: the one who handles the hazmat SKUs is a hazmat employee, the one who does not is not. The definition applied to real jobs and tasks.
Who decides, and who has to act on it?
The employer. 49 CFR 172.702(b) puts the duty to identify, train, test and certify hazmat employees on the hazmat employer — not on the employee and not on a training vendor. What that obligation looks like item by item.

Need to train hazmat employees?

Once someone meets this definition, the employer owes them general awareness, safety and security awareness training, a test and a 172.704(d) record. That is what our course and team plans produce, in English or Spanish.
