SECTION 380:50-23-3. Asbestos-containing ceiling tile abatement procedures  


Latest version.
  •   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.
