We have quite a number of these hoods in place and I see no problem with managing them in place. We have instructed maintenance and laboratory staff of the asbestos content and that they are not permitted to cut into, drill into, or otherwise disturb the hood interior. Any such activity must be referred to us in EH&S and we arrange for whatever work is needed through an asbestos contractor. (For example, flow monitors were installed into the units many years ago, with the contractor drilling all the holes needed for the installation.) Mark Mark R.

Typically, the transite is coated with a chemically resistant paint, perhaps an epoxy formulation. Does anyone see a problem? To me this seems like "managing in place". Regards, Ernest L. Lippert
