Section 380:50-17-5 - Asbestos removal procedures

Asbestos removal procedures are as follows:

(1) Isolate and clean the work area.

(2) Wet all asbestos-containing material with an amended water solution using equipment capable of providing a fine spray mist. Saturate the material to the substrate. However, do not allow excessive water to accumulate in the work area. Keep all removed material wet enough to prevent fiber release until it can be placed in containers for disposal.

(3) Wetted asbestos-containing material shall be removed in manageable sections. If removal procedure uses a mechanical vacuum system, the container the material deposits in shall be in a secured area with hard walls at least eight (8) feet in height and shall be monitored to ensure no exposure to the operator or ambient air. Removed material shall be placed in containers before moving to a new location for continuance of work. Surrounding areas shall be periodically sprayed and maintained in a wet condition until visible material is cleaned up.

(4) Material removed from building structures or components shall not be dropped or thrown to the floor.

(5) Containers (6-mil polyethylene bags or drums) shall be sealed when full. Bags shall not be overfilled. They shall be securely sealed to prevent accidental opening and leakage by tying tops of bags in an overhand knot or by taping in a goose-neck fashion. Do not seal bags with wire or cord. Bagged material may be stored in containment if space allows, or in the first air-lock of the loadout facility. Bags may be placed in drums for staging and transportation to the landfill. Bags shall be decontaminated on exterior surfaces by wet cleaning and HEPA vacuuming before being placed in clean drums.

(6) For transport to the landfill and when not exposed to the elements, components removed intact shall be wrapped in a minimum two layers of 6-mil poly secured with tape.

(7) Asbestos-containing waste with sharp-edged components (e.g. nails, screws, metal lath, tin sheeting) may tear the polyethylene bags or sheeting and shall be placed into drums, or boxes wrapped in a minimum of two layers of 6-mil poly , secured with tape.

(8) After completion of all stripping work, surfaces from which asbestos-containing materials have been removed shall be wet brushed and sponged or cleaned by some equivalent method to remove all visible residue.

(9) Cleanup shall proceed in accordance with Section 380:50-17-8.
