OSHA 29CFR 1910.120, the Hazardous Waste Operations and Emergency Response (HAZWOPER) standard states that 24-hours of HAZWOPER training is the minimum requirement for those employees whose job does not require them to handle waste or hazardous materials as part of their job. However, if they are required to respond to such incidents as uncontrolled releases or the potential of uncontrolled releases, they must respond as first responders to control and possibly perform cleanup operations. This 24-hour class is not designed to be as in-depth as the 40-hour HAZWOPER course.
Employees who have duties requiring them to respond to uncontrolled releases as First Responders at the Operations level, Hazardous Materials Technicians, Hazardous Materials Specialists, and On-Scene Incident Commanders and employees who are expected to handle or clean up hazardous materials or waste should take the 40-hour HAZWOPER course. This course requires participants to don and doff chemically resistant clothing and participate in response activities. Individuals with medical restrictions should not take this course.
