Thanks Barbara for your response! From: [email protected] [mailto:[email protected]] On Behalf Of BJ Thompson Sent: Monday, October 01, 2012 2:37 PM To: [email protected] Subject: Powernet: RE: 3M HEPA Vacuums
Jerry, We no longer use the 3M "tool box" HEPA vacuums. When we did use them, we had minor issues with inadvertent spillage if the HEPA filter or hose/plugs came loose. We normally taped the hose and storage plugs to prevent inadvertent spillage. We labeled the HEPA filter "internal contamination" and used the vendors velcro flap to secure the filter. We did not use any locking device or tamper seals on this type of vacuum. The major disadvantages include: contamination control and clogging on large clean-up jobs. The advantages include: portability and quick set-up. Hope this helps! Barbara J.

If so, do you secure these in any way to prevent inadvertent spillage from the HEPA filter/unit? We use these vacuums, but unlike our other large vacuums that we secure with a lock, etc., to prevent them from opening and spillage of radioactive materials, we have never put similar controls in place for these because the HEPA filter are enclosed in plastic cartridges that slide in an out as a unit with no spillage.
