Inspection in Overhead Spaces Containing Asbestos A simple method saves time and effort. Lyndon B. Johnson Space Center, Houston, Texas A procedure for inspection in spaces above dropped ceilings that contain asbes tos saves time and effort without sacrific ing safety. The conventional inspection method requires elaborate and time-con suming preparation and cleanup: People have to leave the immediate area, and the floor and furniture have to be covered with sheets of plastic. Wearing a respirator, the inspector examines the space above the ceiling. Finally, the room isvacuumdeaned, the plastic sheets are discarded, and the inspector's tods, equipment, and respira tor are cleaned. With the new method, the only items of safety equipment needed are a glove bag, a storage bag, and a roll of adhesive tape. The inspector first tapes the glove bag tightly to the support grid around the ceiling tile to be removed. With hands in the gloves, the inspector lifts the tile gently and places it aside (see figure). Extending head and shoulders into the bag, the inspector examines the space above the ceiling with the help of a flashlight. (A lightweight, col lapsible frame could be used to hold up and spread out the bag so that the inspector could maneuver more easily in the con fined space.) After the examination, the inspector re places the tile, lowers the glove bag, ties it up close to the ceiling, and tapes the storage bag (labeled "For Asbestos") to the ceiling around the glove bag. Finally, the inspector pulls the glove bag loose, drops it into the storage bag, ties the stor age bag closed, and discards the storage bag appropriately. This work was done by Jacque Bell, George Hartwick, andJerry Hutcherson of Pan Am World Services, Inc., for Johnson Space Center. No further documentation is available. MSC-21362 A Transparent Glove Bag gives an inspec tor a clear view of the space above a drop ped ceiling and prevents asbestos from contaminating the area below. D P M C -0230
