At the request of the General Services Administration, two Federal Office Buildings (SIC-9211) in Washington, D.C., and one in Baltimore, Maryland were surveyed to determine if an airborne asbestos (1332214) problem existed in any of the buildings which have asbestos containing material used for fireproofing. The sampling strategy involved the collection of eight air and one bulk sample to establish the extent of asbestos exposures. The analysis of the bulk sample revealed that 90-95 percent of the material was fibrous glass, with the remaining being amosite (12172735) asbestos. All measured fiber concentrations of the air samples were below samples indicated that less than 5 percent of the fibers collected were asbestos. The airborne levels were very low in comparison to OSHA occupational health standards. It is recommended that worker protection and appropriate handling procedures for any future demolition concerning the fireproofing material should be utilized.
