In response to a request from the President of the American Federation of Government Employees Local 3448, an evaluation was made of potential asbestos (1332214) exposure in the Federal Office Building (SIC-9199) located in Evansville, Indiana. Several surface samples revealed chrysotile (12001295) and amosite (12172735) fibers which indicated a history of past airborne asbestos at the site. Of the various air samples taken, only one showed airborne asbestos fibers to be present. This sample contained 0.005 fibers per cubic centimeter (NIOSH guideline, 0.01 fibers per cubic centimeter). Asbestos containing fireproofing (1 to 7 percent chrysotile) was present in the building and was friable, had some water damage, was exposed in the return air plenum, and could be reached through ceiling tiles. The author concludes that a potential health hazard exists. It is recommended that the material be safely removed by a reliable contractor skilled in asbestos abatement. Interim precautionary measures are suggested to allow for building use until the asbestos is completely removed. These include isolating the fireproofing from the supply air source, using only wet janitorial techniques to prevent redispersion of settled dusts, establishing a monitoring system for the facility, designing maintenance procedures which minimize the potential for asbestos exposure, and educating employees as to the nature of the hazard.
