24-Hour HAZWOPER Training Online
This online 24-Hour HAZWOPER training course is designed for occasional site workers and support personnel with low exposure potential under OSHA 29 CFR 1910.120(e)(3)(ii). Learn at your own pace, then complete employer-provided supervised field experience to apply what you have learned on the job.
Who the 24-Hour HAZWOPER Training Course Is For
The 24-Hour HAZWOPER level fits occasional site workers and support personnel who perform tasks at hazardous waste operations or emergency response sites but have a low potential for exposure. These employees typically enter controlled areas under supervision rather than working full time in high-hazard zones. The course aligns with OSHA 29 CFR 1910.120(e)(3)(ii) and 1926.65(e)(3). Employers provide at least one day of supervised field experience to complete on-the-job competency.
- Low exposure potential and non-routine work assignments
- Support roles under supervision (contractors, visitors, helpers, maintenance staff)
- Personnel who may enter controlled work zones but do not routinely work where significant exposure is expected
If your role involves regular entry into high-hazard areas or leading crews, the 40-Hour HAZWOPER or HAZWOPER Supervisor may be more appropriate.

Why 24-Hour HAZWOPER Training Matters
The 24-Hour HAZWOPER course helps employers show that occasional site workers and support personnel receive appropriate training before entering hazardous waste operations or emergency response sites. This level is a strong fit when employees assist with scoped tasks in controlled areas under supervision, rather than working full time in high-hazard zones where higher levels such as the 40-hour course are expected.
People often search for phrases like 24 hour hazwoper online, 24 hr hazwoper training, 24 hour hazwoper certification online, and hazwoper training online $150 when they need OSHA-aligned training that matches a low exposure role. HazMat Student provides a structured, self-paced online course with instant certificates along with guidance on how employers can document supervised field experience and maintain HAZWOPER training records over time.
Because the 24-hour level focuses on occasional and support duties, the training emphasizes hazard recognition, communication, and safe participation in site operations under the direction of supervisors and health and safety professionals. The course supports employers who want to align with OSHA expectations while scaling training programs across locations and contractors.
People Also Ask About 24-Hour HAZWOPER
Is 24-Hour HAZWOPER enough for my job?
If you are an occasional site worker or support person with low exposure potential and you work under supervision, the 24-hour level is often appropriate. If you routinely work in high-hazard zones or direct other workers, your employer may require the 40-hour or supervisor level instead.

Many students complete the online training in a few days, while others spread it out over one to two weeks. Because the course is self-paced, you can log in and out as needed until you pass the final exam and download your certificate.
Do I still need hands-on training after 24-Hour HAZWOPER?
Yes. OSHA expects employers to provide at least one day of supervised field experience for 24-hour students and to add any site-specific or hands-on elements that match actual duties, PPE, and equipment.
Can I move from 24-Hour to 40-Hour HAZWOPER later?
Yes. Workers may upgrade to the 40-hour level by completing additional HAZWOPER training hours and supervised field experience as determined by their employer and job duties.
