I posted this awhile ago & haven't heard - thought I'd try again.
Does anyone have a good method for documenting the ductless hood ANSI Z9.5 requirement for a "hazard evaluation & analysis conducted as directed in ANSI/AIHA Z9.7 and SEction 2.1.1.4"?
Does anyone have a written guide to evaluate lab work & decide when a fume hood is required?
