How to Get HAZWOPER Certified Online
This step-by-step guide shows you how to complete HAZWOPER certification online in line with OSHA 29 CFR 1910.120. You’ll learn the difference between 24 Hour vs 40 Hour HAZWOPER, how supervised field experience works, and how to stay current with the 8 Hour HAZWOPER Refresher.
Step 1 — Confirm your training level
The right course depends on job duties and exposure. Use our 24 vs 40 Hour HAZWOPER comparison and our guide on OSHA Requirements for HAZWOPER Certification to confirm your level:
| Training | Who typically needs it | Hours |
|---|---|---|
| 24 Hour HAZWOPER | Limited or occasional exposure; support roles | 24 hrs + 1 day field experience |
| 40 Hour HAZWOPER | Frequent exposure; cleanup/remediation at uncontrolled sites | 40 hrs + 3 days field experience |
| 8 Hour Supervisor | Supervisors overseeing HAZWOPER operations | 8 hrs (in addition to 24/40) |
Step 2 — Choose an OSHA-accepted provider
Pick a reputable provider that aligns with OSHA’s HAZWOPER standard and issues a certificate of completion. Look for clear instructions on arranging supervised field experience, responsive support, and self-paced online lessons.
Step 3 — Register online
Enroll in the correct course below and start learning right away:
Step 4 — Complete the online lessons
Work at your own pace. Typical topics include hazard recognition, toxicology, site control, PPE, decontamination, monitors and detection devices, emergency response, and the site safety plan.
Step 5 — Finish supervised field experience
OSHA expects hands-on training after the classroom portion. Most workers complete 1 day of supervised field experience for the 24 Hour course or 3 days for the 40 Hour course. Coordinate with your employer or training provider and document completion for your records.
Step 6 — Get your certificate
After you finish the online lessons and any required field experience, download your certificate of completion. Keep a copy for audits and provide one to your employer.
Step 7 — Renew with the annual refresher
Stay current with the 8 Hour HAZWOPER Refresher every year. If too much time has elapsed, your employer may require additional training to restore proficiency.
