Frequently Asked Questions

What is HAZWOPER training?

HAZWOPER is the OSHA standard that applies to certain hazardous waste site operations, treatment and disposal facilities, and emergency response activities involving hazardous substances. Many workers need HAZWOPER training before beginning these duties. If you are unsure which course applies to your role, compare our training options or review our educational resources explaining the difference between 24 Hour and 40 Hour HAZWOPER requirements.

Do I need 24-Hour or 40-Hour HAZWOPER training?

The required training level depends on your job duties and potential exposure to hazardous substances. Workers with greater exposure potential typically require 40-Hour HAZWOPER, while workers with limited exposure may qualify for 24-Hour HAZWOPER. Employers are responsible for determining the appropriate training level.

Is online HAZWOPER training OSHA compliant?

Yes. OSHA allows online HAZWOPER training when it meets the training requirements of 29 CFR 1910.120. Employers must also provide required site-specific instruction, supervised field experience, and hands-on training where applicable.

Does HAZWOPER training require hands-on instruction?

Yes. OSHA requires site-specific hands-on training and supervised field experience for applicable workers. This training is typically provided by the employer because it must address actual workplace hazards and equipment.

Who provides the required HAZWOPER hands-on training?

Employers typically provide site-specific hands-on training because OSHA expects workers to train with the actual PPE, monitoring equipment, work practices, and hazards they will encounter on the job.

How long is a HAZWOPER certificate valid?

Workers who have completed 24-Hour HAZWOPER, 40-Hour HAZWOPER, or Supervisor training generally need an 8-Hour Annual Refresher course every 12 months to maintain compliance and competency.

“The true measure of our training is not the certificate we issue—it is the confidence, competence, and regulatory understanding every student carries into the workplace. We are committed to delivering the highest-quality EHS training while aligning with OSHA, EPA, DOT, and other applicable regulatory requirements. Every course, every lesson, and every resource we create is guided by one purpose: helping workers return home safely.”
