The EPA guidance document on sprayed asbestos (1332214) containing materials in buildings is presented. The nature of asbestos is described and spray application of asbestos is discussed. The spraying of asbestos fibers onto structural surfaces has been the most important source of asbestos exposure to construction workers during application and to the general population thereafter. Asbestos contamination of the environment is examined. Asbestos fiber size and fiber aerodynamics are considered. Asbestos related diseases are described. Existing standards for asbestos exposure are considered. Analytical methods for determining exposure are described. The control of exposure to sprayed asbestos is reviewed. Temporary and long term control measures are considered. Asbestos emission control and personal protection are noted. The basic steps consist of fiber containment and fiber control. Barriers prevent the movement of fibers to other building spaces and environmental areas. Wetting the asbestos containing material will reduce friability, change the aerodynamics of released fibers, and generally increase control effectiveness. Dry and wet removal of asbestos containing materials are discussed. Regulations and compliance by contractors during asbestos removal are considered.
