NISP-RP-08, USE AND CONTROL OF HEPA FILTRATION AND VACUUM EQUIPMENT reads, "When not in the use, then the openings of the HEPA ventilation unit and hoses will be covered to prevent access to any potentially contaminated surface or component."
My questions are; How do you interpret this statement? does your site cover both the intake and discharge ends of a HEPA unit when not in use or when being placed in storage? if you cover the discharge end, why? (since the air came through a HEPA filter). My experience is to cover both ends but, I wanted to see how the rest of the industry handles this or interprets the NISP. Thank you, Dave David J.
