Under US rules, a hazmat employee must receive DOT hazmat training at least once every three years, and the employer must test them on it and keep a record. A free course does not replace that. It helps your team understand, remember and apply it between the formal sessions.
This is a list of 8 ready-made courses for shipping leads, warehouse managers and compliance officers who handle dangerous goods. It starts with awareness and labels, moves to chemicals, and ends with site rules and emergencies. Each group ends with an Our pick.
What DOT hazmat training has to include
The rule lists general awareness, function-specific, safety and security training, and in-depth security training where a security plan applies, all in 49 CFR 172.704. The employer must make sure each hazmat employee is tested on those subjects, and creates and keeps a training record for each one. A hazmat employee is someone employed by, or self-employed as, a hazmat employer who, in the course of that work, loads, unloads or handles hazardous materials, prepares them for transport or operates a vehicle that carries them (the full list is in 49 CFR 171.8).
Function-specific training is about the tasks your people do, so a generic course cannot cover it. The courses below support awareness, labels and emergency response. Your formal programme, run by you or a qualified trainer, stays in place.

Dangerous goods rules
Two courses on the rules for moving and labelling dangerous goods.
DOT hazmat general awareness
This 45-minute course has seven lessons: who a hazmat employee is, the nine hazard classes, shipping papers, markings, labels and placards, emergency response with the Emergency Response Guidebook, and security awareness. It is based on the general awareness, safety and security parts of 49 CFR 172.704. It is awareness only: it does not issue an official card or certificate, and its sixth lesson tells learners which function-specific training they still need. It ends in a 15-question check with an 80 percent pass mark. Ask learners what a diamond-shaped placard on a trailer tells a first responder.
Canada: WHMIS 2015 (classroom portion)
If you ship to or receive from Canada, your colleagues there work to WHMIS, not the US system. This 40-minute course has seven lessons: who is responsible for what, hazard classes and pictograms, supplier and workplace labels, the 16 sections of a safety data sheet, safe procedures, and what to do after a spill, exposure or fire. It is the classroom portion, so add your own site-specific training. Check your own province's rules before you rely on it.
Our pick: DOT hazmat general awareness. It is the only course here written for US hazmat employees, and it shows learners what they still owe beyond it.
Labels and chemical handling
Two courses on reading what is written on the container.
Hazard communication & GHS
OSHA's rule says employers must give employees effective information and training on hazardous chemicals in their work area at the time of their initial assignment, so check whether it applies at your dock. This 40-minute course has eight lessons: how to read a GHS label with its six elements and pictograms, how to find key facts in a 16-section safety data sheet, how to detect a release and what changed in the 2024 update. It ends in a 12-question check. Hand out a real label from your dock and ask what its pictograms mean.
Chemical and hazardous substance safety: labels, data sheets, storage and spills
This global 40-minute course has six lessons: reading labels and pictograms, using the safety data sheet, storage and segregation of incompatibles, first response to spills and leaks, exposure monitoring and decontamination, and the limits of your own role. It includes match-it and order-the-steps activities. Use it as the practical follow-up to the label courses, and add your own storage rules.
Our pick: Chemical and hazardous substance safety. Its keep-apart and spill-response activities are the ones shippers use on the dock every day.
Site rules and emergencies
Four courses for the dock, the yard and the people who visit them.
Safety induction and annual refresher
Drivers, contractors and visitors arrive at your dock and every site has its own rules. This 40-minute course has six lessons: your rights and duties, site rules (access, speed limits, permits and restricted areas), the hazards you will meet, emergency arrangements, reporting hazards and near misses, and rules for contractors and visitors. It opens with a first morning at a depot. Use it as the yearly refresher.
Emergency action & fire prevention plans
OSHA's rule says an employer must review the emergency action plan with each employee covered by the plan when the plan is developed or the employee is first assigned to a job. This 30-minute course has seven lessons on raising the alarm, getting out, your assembly point, staying or sheltering, and preventing fires. Dangerous goods change the fire risk of a dock, so a practised response matters. The rule applies only where an OSHA standard requires a plan, so check with your safety lead.
Fire safety, fire wardens and emergency evacuation
This 40-minute course covers the fire triangle and causes, prevention rules for housekeeping, hot work and storage, choosing and using an extinguisher, evacuation routes and the warden's role in sweeps and head counts. A leak can need a fast, orderly evacuation, and this gives dock staff warden basics. Its extinguisher lesson works well as a match-it quiz.
Safety law, committees, management systems and audits
This 40-minute course explains why the law requires a safety system, employer, manager and worker duties, how a joint safety committee runs, a management system in five steps, and inspections and audits. It shows how safety audits and management systems sit beside your DOT paperwork. It is global, so add your own law.
Our pick: Emergency action & fire prevention plans. A dangerous-goods dock needs a practised way out, and this one ends in a scored check.
How to roll the plan out
Start with the formal duty: confirm who counts as a hazmat employee, schedule the DOT training and testing, and make sure each record is kept. Then use DOT hazmat general awareness and the label courses to prepare new starters before that training. Put the site induction into onboarding. Schedule the chemical, emergency and fire courses as annual refreshers, and add any state or country rule for your location.
Anchor each refresher to the same fact: the formal training comes round at least once every three years, so the courses here keep the knowledge fresh in between. If your team also drives, our driver safety training list covers the road, and our workplace safety topics cover talks for the dock.
Ways to run these courses on AhaSlides
You can offer all 8 in three formats:
- Self-paced courses. Use the AhaSlides course creator to send each new starter a course before their first shift on the dock.
- A live Q&A deck. Collect questions ahead of the session, then answer them in the warehouse or online. For running it well, see our 9 tips for a successful Q&A session.
- Surveys. Use the post-course survey and 30-day check-in that come with each template, and see how to track employee training completion.
Four slide types do most of the work:
- Pick Answer. Ask: "Which hazard class does this placard show?" Show the split before you reveal the answer.
- Word Cloud. Ask: "What is the first thing you check on a package?" The biggest words show where the team needs practice.
- Rating Scale. Ask, before and after: "How confident are you reading a safety data sheet?" Rate from 1 to 5 and compare the averages.
- Open Ended. Ask: "What would you tell a new starter about our storage rules?" Answers can be anonymous, so people say what they think.
FAQ
What training is required for hazmat shippers?
General awareness, function-specific, safety and security training under US DOT rules. The rule in 49 CFR 172.704 also covers in-depth security training where your company needs a security plan.
How often is DOT hazmat training required?
At least once every three years. A hazmat employee must receive the training at least once every three years, and a new employee or one who changes job functions must finish it within 90 days, working under the direct supervision of a trained hazmat employee until then.
Can I complete DOT hazmat training online?
Yes, the rule lets training come from the employer or other public or private sources. The employer must still test each employee and keep the record, so a free awareness course is a supplement, not the record.
What is general awareness hazmat training?
It is an introduction to the hazmat rules that helps an employee recognise and identify hazardous materials. The general awareness course covers it in 45 minutes and does not issue an official card.
