Asbestos abatement enclosure procedures are as follows:
- (1) Isolate and clean the work area in accordance with Section 380:50-17-4.
- (2) Spray areas that will be disturbed during the installation of hangers or other support/framing materials for the enclosure with water containing the specified surfactant. Keep these areas damp to reduce airborne fiber concentrations.
- (3) Remove loose or hanging asbestos-containing materials in accordance with the requirements of Section 380:50-17-5.
- (4) After installation of hangers and other fixing devices and before installation of enclosure, repair damaged areas of fire-proofing/thermal insulation materials as required using a non-asbestos-containing replacement material. Prepare surfaces and apply replacement material in accordance with manufacturer's recommendations.
- (5) Use hand tools equipped with HEPA filtered local exhaust ventilation to drill, cut into, or otherwise disturb asbestos-containing materials during the installation of support systems for the enclosures. (Alternatively, these areas of material could be removed prior to installation of supports.)
- (6) Use materials that are impact resistant and that will provide an airtight barrier once construction is complete.
- (7) Move utilities as necessary and reinstall in a manner which permits proper utilization and does not disturb the integrity of the enclosures.
- (8) Enclosed asbestos-containing materials shall be designated in accordance with Section 380:50-17-6(8) in order to warn building maintenance personnel in the event they are required to disturb the enclosure.
