NYS Asbestos Project Monitor Refresher Reviews

I had a thorough refresher. Tricky question about "recommended" respirator cartridge replacement gets me every time. I know that I'd replace the cartridge when it became more difficult to breathe thru but I would always replace once the cartridge got drenched in the shower. Good to see you again, Angelo. Glad you're "out there" for us. Regards, Henry Alilionis
