• Description:
  The air handling machine room and the ventilation system in use at the Defense Logistics Agency (SIC-9711) Health Clinic and Inspector General's Office in Philadelphia, Pennsylvania were evaluated to determine potential exposure to asbestos (1332214). A walk through survey and bulk residue sampling were conducted on April 3 and 25, 1980 at the request of the Agency. Improper removal of asbestos insulation from an old ventilator was identified as a potential source of asbestos contamination
  
  fibers may have entered the new ventilation system and could expose over 5,500 personnel to asbestos within 1 year. Analysis by polarized light and electron microscopy revealed that 10 to 30 percent of the bulk samples were chrysotile- asbestos (12001295), in the form of free fibers and large chunks of material. The current OSHA asbestos exposure standard for an 8 hour time weighted average is 2.0 fibers per cubic centimeter for greater than 5 microns in length, but the authors note that there is no truly safe exposure limit for asbestos. They conclude that a hazard would exist if the new air system at the clinic is put in operation. They recommend a thorough cleaning of the room and the ventilation system, followed by an appropriate air monitoring program. [Description provided by NIOSH]
