6 Asbestos is the generic term for a group of naturallyoccurring, fibrous minerals with high tensile strength,flexibility, and resistance to heat, chemicals, and the Construction Industry , Asbestos is found in installedproducts such as sprayed-on fireproofing, pipe insulation,floor tiles, cement pipe and sheet, roofing felts and shingles,ceiling tiles, fire-resistant drywall, drywall joint compounds,and acoustical products. Because very few Asbestos -containing products are being installed today, most workerexposures occur during the removal of Asbestos and therenovation and maintenance of buildings and structurescontaining are the dangers ofasbestos exposure? Asbestos fibers enter the body when a person inhalesor ingests airborne particles that become embedded in thetissues of the respiratory or digestive systems.

7 Exposureto Asbestos can cause disabling or fatal diseases such asasbestosis, an emphysema-like condition; lung cancer;mesothelioma, a cancerous tumor that spreads rapidly inthe cells of membranes covering the lungs and body organs;and gastrointestinal cancer. The symptoms of these diseasesgenerally do not appear for 20 or more years after Construction activitiesdoes this booklet cover?The Asbestos Standard for the Construction Industry (29 CFR Part , see ) regulatesasbestos exposure for the following activities: Demolishing or salvaging structures where Asbestos Removing or encapsulating Asbestos -containing material(ACM). Constructing, altering, repairing, maintaining, orrenovating Asbestos -containing structures or substrates.

8 Installing Asbestos -containing products. Cleaning up Asbestos spills/emergencies. Transporting, disposing, storing, containing, andhousekeeping involving Asbestos or Asbestos -containingproducts on a Construction : The Standard does not apply to Asbestos -containingasphalt roof coatings, cements, and ofthe OSHA StandardOSHA has established strict exposure limits andrequirements for exposure assessment, medical surveillance,recordkeeping, competent persons, regulated areas, andhazard is work classification?The OSHA Standard establishes a classification systemfor Asbestos Construction work that spells out mandatory,simple, technological work practices that employers mustfollow to reduce worker exposures. Under this system, thefollowing four classes of Construction work are matchedwith increasingly stringent control requirements: Class I Asbestos work is the most potentially hazardousclass of Asbestos jobs.

9 This work involves the removalof Asbestos -containing thermal system insulation andsprayed-on or troweled-on surfacing materials. Employersmust presume that thermal system insulation and surfacingmaterial found in pre-1981 Construction is ACM. Thatpresumption, however, is rebuttable. If you believe thatthe surfacing material or thermal system insulation is notACM, the OSHA Standard specifies the means that youmust use to rebut that presumption. Thermal systeminsulation includes ACM applied to pipes, boilers, tanks,ducts, or other structural components to prevent heat lossor gain. Surfacing materials include decorative plaster onceilings and walls; acoustical materials on decking, walls,and ceilings; and fireproofing on structural members.

10 Class II work includes the removal of other types of ACMthat are not thermal system insulation such as resilientflooring and roofing materials. Examples of Class II workinclude removal of Asbestos -containing floor or ceiling tiles,siding, roofing, or transite panels. Class III Asbestos work includes repair and maintenanceoperations where ACM or presumed ACM (PACM) Class IV work includes custodial activities where employeesclean up Asbestos -containing waste and debris produced byconstruction, maintenance, or repair activities. This workinvolves cleaning dust-contaminated surfaces, vacuumingcontaminated carpets, mopping floors, and cleaning upACM or PACM from thermal system insulation orsurfacing is the permissibleexposure limit for Asbestos ?
