Worker exposures to asbestos (1332214) were surveyed on July 20, 1983 at the George H. Fallon Building in Baltimore, Maryland. The evaluation was requested by Senator Paul Sarbanes on beh lf of about 2200 building residents, to determine the extent to which asbestos had been used, any potential hazards, and necessary abatement measures. Air, settled dust, and bulk fireproofing material samples were collected and analyzed for the presence of asbestos fibers. Air fiber concentrations were below the 0.01 fiber per cubic centimeter limit of detection, and no asbestos fibers were found by transmission electron microscopy. Polarized light microscopic examination of settled dust samples also failed to reveal any asbestos fibers. The bulk samples of the fireproofing material contained 5 to 20 percent crysotile asbestos. The author concludes that no asbestos exposure hazard existed at the time of this survey. He recommends covering an encapsulation of any areas of exposed asbestos, use of accepted control measures during any renovation or maintenance activities, implementation of a respiratory program, periodic inspection and monitoring of the building for the presence of free asbestos fibers, and removal of the fireproofing materials if future monitoring reveals the presence of asbestos fibers in normal work areas.
