NES has produced this online refresher course to provide a learning experience that lets you pick the time and place to complete the coursework required to renew your HAZWOPER certification. Hazardous waste site employees and supervisors must receive an annual refresher to maintain their certification; our web-based course is the most convenient way to go! When taking the course, the software remembers what sections you’ve taken and picks up where you left off. Once you have signed up you will have 30 days to complete your course. Once completed, you will be able to come back any time to access your certificate.
Please note that workers not completing an annual refresher after one year cannot work at a qualified site. Cal OSHA requires completion of a refresher within 24 months of the last refresher (or initial 24- or 40-hour HAZWOPER training) to avoid having to re-take 24- or 40-hour HAZWOPER training; federal OSHA has set no explicit time frame.
