ABOUT THIS EXAM · OSHA
HAZWOPER (Hazardous Waste Operations and Emergency Response)
OSHA-required training (not a credential — no central registry). The wallet card from your trainer is your proof. Stanley's tip: keep both your initial 40-Hour card AND every annual 8-hour refresher card; missing one breaks the chain and you're back to 40 hours.
