Asbestos is a naturally occurring fibrous mineral. Inhalation of asbestos may contribute to development of lung cancer, asbestosis or mesothelioma. Regulation of public exposure to asbestos is controlled by the Environmental Protection Agency or EPA. The Occupational Safety and Health Administration, also known as OSHA, regulates occupational exposure. EPA and OSHA regulations cover the removal of asbestos-containing materials.
EPA Regulations
Under the National Emission Standards for Hazardous Air Pollutants or NESHAP, owners and contractors are required to notify the EPA and any applicable local or state agency of all planned demolition. Demolition includes renovation, if the renovation is to load-supporting materials. A person trained in NESHAP asbestos removal must be present during renovation. Vehicles used for removal of asbestos-contaminated material must indicate that they contain asbestos.
OSHA Regulations
OSHA limits occupational exposure to asbestos to 0.1 fibers per cubic centimeter. Persons employed to remove asbestos present in greater amounts must be provided with full body covering clothing, respirator, gloves and ventilated goggles. Employer-sponsored training is required before employees can begin asbestos removal. Areas containing the contaminant must be labeled. Eating, drinking, chewing gum, smoking, and application of cosmetics is prohibited in the area. A separate decontamination facility must be provided.
Technique
Wet down asbestos-contaminated materials to prevent dissemination of asbestos particles into the air. Use polyethylene plastic sheeting and duct tape to curtain off the contaminated area. "Asbestos Removal Procedures for Home Owners" recommends use of 6 mil polyethylene sheeting. Dispose of contaminated materials in asbestos waste bags. Seal the waste bags with duct tape. Use a wet rag to wipe residue from surfaces. Dispose of rag into waste bags.
