Removal of friable asbestos-containing ceiling tile may be done using the following procedures.
- (1) All required Department of Labor notices and State Department of Environmental Quality NESHAPS notices must be filed with those agencies.
- (2) Prior to the start of the ceiling tile removal project, the Department of Labor must make an on-site inspection of the area to determine the applicability of these procedures. The inspector will determine at that time if electrical power above the ceiling grid must be de-activated.
- (3) All air handler units (heaters, air-conditioners, blowers) must be turned off.
- (4) The ceiling tile removal may only be done when the work area is not occupied.
- (5) All movable items must be removed from the room.
(6) Decontamination facilities must be established, but need not be contiguous with the tile removal area provided:
- (A) Workers can travel to the facilities without endangering the general public or the environment.
- (B) Workers are thoroughly HEPA vacuumed and wear a clean protective suit over the existing suit.
- (7) Critical barriers must be erected.
- (8) Workers must wear protective full body coveralls and full-face respirators.
- (9) Negative air machines in the tile removal area must be installed, vented internally, and provide a minimum of one air change each 30 minutes. A 6-mil poly drop cloth must be used under the work teams, in case a tile falls.
- (10) Workers shall work in teams, with one worker removing and bagging tiles, and one worker holding a HEPA vacuum near the grid.
- (11) Tiles must be placed in 6-mil asbestos-marked bags, sealed with duct tape. This bag must be placed in a second bag for transport.
- (12) The tiles must be disposed of in an approved asbestos landfill, and copies of waste shipment records provided to the Department of Labor.
- (13) The grid shall be HEPA vacuumed and wet wiped.
- (14) Air monitoring tests must be run in accordance with Subchapter 11 of these rules.
