CONTROL AND PREVENTION OF ASBESTOS EXPOSURE FROM CONSTRUCTION IN NATURALLY OCCURRING ASBESTOS

Construction projects in Fairfax County, Virginia, routinely disturb amphibole mineral deposits causing actinolite asbestos and tremolite asbestos fibers to become airborne. These same mineral formations exist extensively on the east and west coasts of the United States. Asbestos is regulated by federal, state, and local authorities as a proven human carcinogen. The air-monitoring data presented in this paper show that construction projects in naturally occurring asbestos can produce asbestos exposures to workers and the public. These construction projects can be monitored using standard airborne fiber sampling and analysis techniques, National Institute of Occupational Safety and Health (NIOSH) 7400, and the Occupational Safety and Health Administration (OSHA) reference methods. Exposure to asbestos can create a significant, long-term, liability problem unless prudent actions are taken by responsible parties to prevent asbestos fibers from becoming airborne. The regulations created by the Fairfax County Air Pollution Control Division (APCD) and OSHA 29 CFR 1926.58 are reviewed. The Fairfax County APCD Control Requirement Directives 1 and 2 are designed to control fugitive dust, establish air monitoring, and require safe disposal and covering of soil. The effective work practices used to control fugitive asbestos emissions from the construction projects are discussed. Construction projects can safely be completed if these regulations and work practices are followed.
