I conducted air monitoring for asbestos on May 16-17/ 1988 at
the PDC change-house facility. Gillian HFS-113A high flow pumps
were used in conjunction with 25 mm ncef filters to measure airborne
concentration of asbestos. Contract personnel were monitored on two
separate days while removing asbestos insulation from pipirig and a
boiler in the change-house. Results of the air monitoring `are
included in the attachment/ Table 1. The exposures do not exceed
the OSHA PEL of O'.2 fibers/cc. It should -be noted that personnel
wore respiratory protection and protective clothing while performing
the operations.
