SECTION 380:50-23-4. Asbestos-containing ceiling texturing procedures
Latest version.
- Many ceilings of schools, office buildings, and homes have been constructed of gypsum board covered with a thin layer of texturing compound, and then painted. Much of this texturing compound contains small asbestos particles to provide the textured surface. This type ceiling, when in place and undamaged does not constitute a significant health risk. The Labor Department does not consider the painting of such a ceiling to be an asbestos encapsulation, and therefore does not require such painting to be done by an asbestos contractor, and no special precautions related to asbestos need be taken. If the texturing material is seriously damaged or de-laminates, an individual determination of the potential risk must be made. Removal of this material constitutes an asbestos abatement project and 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) All air handler units (heaters, air-conditioners, blowers) must be turned off.(3) The ceiling texturing removal may only be done when the work area is not occupied.(4) All movable items must be removed from the room.(5) Decontamination facilities must be established, but need not be contiguous with the ceiling texturing removal area if workers can travel to the facilities without endangering the general public or the environment.(6) Critical barriers must be erected.(7) A single layer of wall and floor poly must be erected in compliance with the requirements of Section 380:50-17-4 of these Rules.(8) Workers must wear protective full body coveralls and full-face respirators.(9) Negative air machines must be installed in the removal area, vented internally, and provide a minimum of one air change each 30 minutes.(10) Air monitoring tests must be run in accordance with Subchapter 11 of these rules.
