OSHA DOT Training: What It Is and How to Stay Compliant
If you’re searching for OSHA DOT training, you likely have employees who handle chemicals, ship hazardous materials, or work around regulated substances—and you want to know what training is required, by whom, and how to document it. The key is understanding that OSHA and DOT regulate different parts of hazardous materials safety. Many workplaces need both to meet legal obligations and reduce risk.
This guide from SwiftSDS explains what OSHA DOT training typically covers, which regulations apply, and how to build a practical workplace hazardous materials training program that holds up during audits and inspections.
OSHA vs. DOT: Why “OSHA DOT Training” Is Usually a Two-Part Program
“OSHA DOT training” isn’t a single standardized course in federal law. It’s a common shorthand for the combined training employers need when:
- Employees work with hazardous chemicals (OSHA jurisdiction), and/or
- Employees prepare, offer, or transport hazardous materials in commerce (DOT jurisdiction)
OSHA training foundation: HazCom and workplace chemical safety
Under OSHA’s Hazard Communication Standard (29 CFR 1910.1200), employers must train employees on hazardous chemicals in the workplace, including labeling, Safety Data Sheets (SDS), and protective measures. This is the backbone of workplace hazardous materials training for most industries.
You can place this topic within your broader HR program by aligning it with your overall human resources compliance training framework.
DOT training foundation: Hazmat employee training
Under the U.S. Department of Transportation’s Hazardous Materials Regulations (HMR) (49 CFR Parts 171–180), any “hazmat employee” must receive required training if they:
- Classify hazardous materials
- Package, mark, label, or placard shipments
- Prepare shipping papers
- Load/unload hazmat
- Operate vehicles transporting hazmat
- Perform hazmat-related security duties
Even office staff can be “hazmat employees” if they prepare shipping documents.
Who Needs OSHA DOT Training? Common Job Roles and Scenarios
A good compliance test: if a person can affect chemical safety in the facility (OSHA) or hazmat safety in transportation (DOT), they need training.
Roles that often trigger OSHA HazCom training
- Production, maintenance, and warehouse teams handling chemicals
- Janitorial staff using industrial cleaners
- Lab and quality control personnel
- Supervisors responsible for chemical controls
Roles that often trigger DOT hazmat training
- Shipping/receiving and logistics staff preparing hazmat shipments
- Warehouse staff packaging or labeling hazmat
- Fleet/transportation teams moving regulated materials
- Managers overseeing hazmat shipping compliance
If you’re building a structured training roadmap, start with your baseline basic health and safety course and then add role-specific HazCom and DOT modules.
What OSHA Requires for Workplace Hazardous Materials Training (Actionable Checklist)
OSHA’s HazCom standard requires effective training at the time of initial assignment and whenever new hazards are introduced. At a minimum, ensure your training covers:
1) Chemical hazard information employees can use immediately
- The hazards of chemicals in the work area (health + physical hazards)
- How to detect the presence or release of chemicals (e.g., monitoring, odor, visual cues)
- The details of your written HazCom program
2) Labels and SDS access (non-negotiable in inspections)
- How to read container labels (including pictograms, signal words, hazard statements)
- How to access and use Safety Data Sheets
- Where SDS are located during every shift (including after-hours)
3) Protective measures and emergency procedures
- Required PPE and safe handling practices
- Spill response expectations and reporting
- First aid measures and exposure response basics (as applicable)
Many employers reinforce this training as part of annual safety training to keep knowledge current and reduce incident rates.
What DOT Requires for Hazmat Employees (49 CFR 172.704)
DOT training requirements are more prescriptive than many employers expect. Under 49 CFR 172.704, hazmat employees must receive:
1) General awareness / familiarization training
Overview of hazmat regulations and how to recognize hazardous materials.
2) Function-specific training
Training tailored to the employee’s actual job duties—e.g., packaging selection, marking/labeling, shipping papers, or segregation requirements.
3) Safety training
Emergency response information, protective measures, and accident avoidance.
4) Security awareness training
Basic security risks and how to respond to threats.
5) In-depth security training (only if you have a DOT security plan)
If your company is required to maintain a hazmat security plan (49 CFR 172 Subpart I), employees must receive in-depth security training relevant to their responsibilities.
Timing and retraining: DOT requires recurrent training at least once every three years, and initial training must occur within 90 days of employment/role change, with supervision restrictions during that window.

Documentation and Recordkeeping: What to Keep (and How Long)
Training doesn’t “count” if you can’t prove it. Build a simple audit-ready recordkeeping process.
OSHA (HazCom) documentation best practices
OSHA doesn’t prescribe a single HazCom training record format, but you should retain:
- Training dates, attendance, and topics covered
- Trainer qualifications or training source
- Materials used (slides, handouts, quiz results)
- The current written HazCom program and chemical inventory
DOT (Hazmat) training records are explicitly required
DOT requires records including:
- Employee name
- Most recent training completion date
- Description/copy of training materials
- Name/address of trainer
- Certification that the employee was trained and tested (as applicable)
Retention: Keep DOT training records for as long as the employee is employed and for 90 days thereafter.
Multi-State and Local Considerations: Training + Posting Requirements
While OSHA and DOT are federal, state plans and local enforcement realities affect compliance priorities (and audits). Also, “compliance” in HR often includes required workplace postings alongside training.
- For employers with Ohio locations, review Ohio (OH) Labor Law Posting Requirements to confirm you’re meeting posting obligations that may be checked during visits or complaints.
- If you operate in Alabama, location-based requirements can vary—see Dothan, Houston County, AL Posting Requirements or Ashford, Houston County, AL Posting Requirements depending on your site.
- For Arkansas workplaces, confirm posting compliance through Hazen, Prairie County, AR Posting Requirements.
If you have Massachusetts operations, postings and worker-right-to-know notices frequently come up during compliance reviews. Consider including these in your compliance binder and onboarding workflow:
- Massachusetts Workplace Safety and Health Protection for Public Employees
- Your Rights under the Massachusetts Temporary Workers Right to Know Law
(Training and posting compliance are different requirements, but they’re often reviewed together in real-world HR audits.)
How to Build an OSHA DOT Training Program That Works (Practical Steps)
Step 1: Identify regulated chemicals and hazmat shipping activities
- Maintain a current chemical inventory (OSHA HazCom)
- Map shipping workflows to identify hazmat employee functions (DOT)
Step 2: Assign training by job function—not by job title
Create a matrix: role → tasks → required OSHA topics → required DOT modules.
Step 3: Standardize onboarding + recurrent training schedules
- OSHA HazCom: at assignment and when new hazards are introduced (many employers also refresh annually)
- DOT Hazmat: initial within 90 days; recurrent every 3 years
Step 4: Validate learning and keep records centralized
Use quizzes, demonstrations, or supervisor sign-offs. Store records in one place so HR can produce them quickly.
Step 5: Develop internal capability over time
If you’re building deeper EHS expertise, explore environmental health and safety certification programs for safety leaders and program owners.
FAQ: OSHA DOT Training
Is “OSHA DOT training” required by law as one course?
No. OSHA and DOT have separate training requirements. Many employers bundle them into a coordinated program because the same employees may handle chemicals at work (OSHA) and prepare shipments for transport (DOT).
How often do employees need DOT hazmat training?
Under 49 CFR 172.704, recurrent DOT hazmat training is required at least every three years, plus training when job functions change.
Do employees who only handle chemicals in the facility need DOT training?
Usually not. If they do not perform hazmat functions related to transportation (packaging, labeling, shipping papers, offering into commerce), DOT training may not apply—but OSHA HazCom training under 29 CFR 1910.1200 likely still does.
SwiftSDS helps HR teams connect training requirements to the real compliance landscape—policies, documentation, and posting obligations—so your workplace hazardous materials training program is both effective and defensible.
