California HAZWOPER Training FAQs

California’s hazardous waste operations and emergency response (HAZWOPER) rules for general industry workplaces mirror federal rules, with additional requirements for safety and health plans and personal protective equipment that are stricter than the federal rules (8 CCR 5192).

The CA Department of Industrial Relations/Division of Occupational Safety and Health (Cal/OSHA) administers and enforces workplace safety and health rules for private and public sector workplaces in the state.

Is HAZWOPER mandatory in California?

The California Division of Occupational Safety and Health (DOSH), also known as Cal/OSHA, works to protect workers and improve the health of those working in California. Cal/OSHA also aids in the safety of passengers riding on elevators, tramways, and amusement rides. The regulations protect through the following events: 

  • Establishing and enforcing standards
  • Offering outreach, assistance, and education
  • Issuing permits, approvals, licenses, certifications, and registrations

Employees and employers in California who are covered by the OSHA HAZWOPER standard must take the initial HAZWOPER training. This initial training consists of a 24-hour course or a 40-hour course. The course you take depends on your job. 

After the initial training requirement is met every year, workers must complete an 8-hour HAZWOPER refresher course. The refresher course fulfills the annual training requirement for all hazardous waste operations and emergency response (HAZWOPER) workers.

Who does the HAZWOPER standard apply to?

According to the Occupational Safety and Health Administration (OSHA), five groups of employees and employers are covered by the HAZWOPER standard. This standard specifically includes any employees exposed to hazardous or potentially hazardous substances. 

The HAZWOPER standard also covers those who engage in several operations, including clean-up, storage, treatment, and hazardous waste disposal. 

The HAZWOPER standard also applies to those involved in emergency response operations that deal with hazardous waste. This includes workers who must perform duties at a waste site where hazardous contamination is possible.

What is a hazardous substance or situation?

OSHA provides guidance as to what defines a hazardous substance or situation. OSHA lists the following substances and situations:

  • Areas with large concentrations of toxic materials
  • A situation that is potentially life or injury threatening
  • Impending Danger to Life and Health (IDLH) environments
  • Situations that present an oxygen-deficient atmosphere
  • Conditions that pose a potential fire or explosion hazard
  • Situations that require an evacuation 
  • Situations that require immediate attention due to the danger posed to employees

What are California's state HAZWOPER requirements?

All California workers who handle hazardous or potentially hazardous materials must take a 24-hour or 40-Hour HAZWOPER training course followed by an 8-hour annual refresher training.
