HAZWOPER 40-hour is required for workers that perform activities that expose or potentially expose them to hazardous substances. In order to comply with OSHA’s Hazardous Waste Operations and Emergency Response (HAZWOPER) Regulations, employees may need to be provided with “site-specific” information, as well as “hands-on” training, in addition to the course. This course is designed to be completed in approximately 40 hours and can complete within 10 weeks.
