The short answer
Yes. 49 CFR 172.704 prescribes what a hazmat employee must be trained on and requires that they be tested. It does not prescribe a delivery method, and PHMSA has long accepted computer-based training. What decides whether an online course actually holds up is not the format: it is whether the applicable content is genuinely covered, whether the employee is genuinely tested, and whether the employer ends up holding the record 172.704(d) requires.
Why the rule allows it
Read 172.704 looking for a delivery requirement and you will not find one. Paragraph (a) lists content categories. Paragraph (c) sets deadlines and the recurrent cycle. Paragraph (d) sets out the record. Nowhere does it require a classroom, an instructor in the room, a minimum number of hours, or a proctor.
That is not an oversight. The rule is written around outcomes — the employee knows the material and has been tested on it — rather than around a format that would have aged badly. It is the same reason an employer can deliver some of the training itself: what matters is that it happened, that it was tested, and that it is documented.
The three conditions that actually matter
| Condition | Where it comes from | What to check in any course |
|---|---|---|
| The applicable content is covered | 172.704(a)(1)–(a)(5) | Does the course state which paragraphs it covers, and which it does not? A course that will not tell you its limits has not thought about them. |
| The employee is tested | 172.704(c)(1), (d)(5) | Is there a real assessment with a passing score, and does the documentation show it was passed? |
| The employer ends up with the record | 172.704(d) | Do you receive a document carrying all five required items — or only a decorative certificate? |
Our course states its coverage on every page and prints it on both documents; the assessment has an 80% passing score printed on the certificate; and the 172.704(d) record carries the five items with a certification block for the employer. Open the sample record and check it against the list above before you buy anything from anyone.
The part online training cannot do
It requires training on the measures and procedures in place at the employee's own facility to protect them from the hazards they may be exposed to. No vendor knows your site. If an online course claims to satisfy the whole of 172.704, that claim is wrong, and it is wrong for every vendor equally — including us. What we cover and what we do not.
The same goes for function-specific training beyond what a general course can reach. A baseline for warehouse handling and shipping papers is deliverable online; training on filling a cargo tank at your terminal is not. General awareness vs function-specific.
Where online genuinely wins
- The 90-day window closes in week one instead of waiting for a scheduled class. The 90-day rule.
- Language per employee. A mixed crew can train in English and Spanish at the same time, with each record stating the language of instruction.
- The record is generated, not typed. Hand-written records are where the five items go missing.
- Retraining does not need a room. A three-year cycle across a rotating crew becomes a scheduling problem you no longer have.
Common questions
Does the regulation say online training is acceptable?
Is there a minimum number of hours?
Does the employee have to be watched while taking it?
Is a printed certificate enough for an inspection?
