1. Does your facility use the Dioctyl Phthalate (DOP) chemical to perform filter integrity tests on HEPA's and vacuums that contain a HEPA filter on a scheduled rotation?
2. If you do not use DOP, what testing do you use and why? 3. Does your facility issue vacuums with HEPA filters by a written check out system and maintain them locked when not in use? 4. Does your facility use locking devices or seals that would give evidence that the vacuum containing a HEPA filter had been opened or the filter tampered with? Any associated documentation pertaining to these questions may be forward to [email protected]<mailto:[email protected]> or [email protected]<mailto:[email protected]> Respectfully, Corey A.
