Who Should Take This Course?

This online OSHA 16 Hour HAZWOPER Upgrade (to the 40 Hour) course is designed for workers who have completed their 24 Hour HAZWOPER training and want to upgrade to the 40 Hour HAZWOPER training level. Workers who should take the 100% online class:

  • will not be using any of the equipment on the job, OR
  • will use equipment on the job, but will have employer-provided hands-on training on the specific equipment they will use

This training meets the Federal OSHA HAZWOPER training requirements of 29 CFR 1910.120(e)(3)(iv) and 29 CFR 1929.65(e)(3)(iv).

Students who took the 24 Hour HAZWOPER course from another training provider, and enroll in our OSHA 16 Hour HAZWOPER Upgrade Online course, must provide acceptable documentation of 24 Hour course completion before the 40 Hour certificate can be provided.

In place of hands-on training, students in this course will view 50 short video clips which demonstrate the HAZWOPER equipment and donning/doffing procedures in great detail. Students may review the videos as often as needed during the course. The online HAZWOPER training course does not give students the ability to handle the tools and equipment.

We also offer our OSHA 16 Hour HAZWOPER Upgrade Combo (Online/Classroom) course as an option, which provides hands-on training. The equipment we train with may vary slightly from the specific equipment that you will use as part of your job. Any worker required to use specialized equipment must be trained on the proper use of that equipment prior to use.
