I have already taken a 40 hr HAZWOPER course some years ago. Do I need to take the 40 hr course again or can I do the 8 hour refresher course?

Tiffany: Hi, Kevin !My name is Tiffany. Welcome to ComplyChat!How are you today? 
Kevin : Hello
Tiffany: Per OSHA regulations the 40-Hour HAZWOPER does require an annual 8-Hour HAZWOPER to stay certified.  If you did not do the 8-Hour annual refreshers we would advise completeing the 40-Hour HAZWOPER again. 
Kevin : How long does the 40 hour HAZWOPER stay valid for? 
Tiffany: One year unless you do the 8-Hour HAZWOPER annual refreshers, annually after you have the 40-Hour HAZWOPER certification to keep it current.  
Kevin : Ok. Thank you!
