• Description:
  Environmental and personal air samples and ceiling, wall, and floor dust bulk samples were analyzed for the presence of asbestos (133221A) at the National Zoological Park Reptile House (SIC-8421), Washington, D.C. on November 9, 1978. The evaluation was requested by the Office of Police and Safety at the zoo on behalf of an unspecified number of workers and the general public. The visitor and service areas had no detectable airborne asbestos fibers. The ceiling sample contained 70 percent chrysotile-asbestos (12001295), but no asbestos was detected in wall and floor samples. The investigators note that the OSHA standard for asbestos is an 8 hour time weighted average airborne concentration not to exceed 2,000,000 asbestos fibers longer than 5 microns per cubic meter (Cu m) of air, with ceiling concentrations never to exceed 10,000,000 fibers longer than 5 microns/Cu m. They conclude that airborne asbestos fibers are not a potential health hazard to workers or to the public in the Reptile House. They recommend that roof leaks and damaged hot water pipes covered with asbestos be repaired, the asbestos ceiling be removed completely when the building is renovated, and bulk samples of floor sweepings be analyzed every 6 months until renovation is completed.
