The 8-Hour HAZWOPER refresher course meets all of the requirements outlined in OSHA 29 CFR 1910.120 for eight hours of HAZWOPER annual refresher training for workers who remove waste and could potentially be exposed to hazardous substances.


Employers seeking compliance with OSHA’s Hazardous Waste Operations and Emergency Response Standard should provide this refresher course for their employees who may be exposed to potentially dangerous substances. 


This course is self-paced with nine modules and a quiz at the end of each module. Access to the course is granted for one full year. After completing the course, a certificate of completion is available for download.


Some topics that are covered are:

  • Decontamination
  • Toxicology
  • Levels of Protection
  • Detecting Hazardous Materials
  • Respirators
  • Site Safety Planning
  • Hazardous Communication
  • Hazardous Waste
  • The Occupational Safety and Health Administration (OSHA) has guidelines for those working with hazardous materials. It is recommended by OSHA, that companies with employees and contractors who work with and around hazardous materials, should take safety training courses and the applicable certifications. It has been found that those who take these training courses, have less workplace injuries. 


Who Needs the 8-Hour HAZWOPER Refresher?


The 8-hour refresher is designed for workers at uncontrolled hazardous waste operations who previously completed the 24-hour HAZWOPER Training Course  or the 40-hour HAZWOPER  Training Course. The certification lasts for up to 12 months. Employees must complete the refresher training within that year to avoid repeating their initial 24-hour or 40-hour training. 


The amount of daily exposure to hazardous materials, will determine which initial course needs to be taken.


  • There is a 24-hour HAZWOPER course, for those who work near or with hazardous materials under permissible exposure limits.
  • Those who work with or near hazardous waste that is above permissible exposure limits must take the 40-hour HAZWOPER course. This course covers topics dealing with Hazardous Waste Operations and Emergency Response. This includes hazardous chemicals, radiation hazards, personal protective equipment and decontamination methods. 




Employees must follow specific work guidelines, policies, procedures and practices in order to protect workers on the job who could be exposed to hazardous materials. All workers must be trained in each of their fields, so they can perform their duties safely.


The goal is to complete a job without danger to the employee or others. As mentioned, there are different levels of OSHA HAZWOPER guidelines, depending on the type of work done. There are 22 State OSHA approved plans for local government, state workers and the private sector. These state plans are constantly monitored by OSHA and must prevent workplace death, injuries and illnesses.
