Description:
This report describes the implementation and testing of control measures to reduce airborne asbestos generated by the drilling of asbestos-containing flooring materials, an OSHA Class III asbestos maintenance activity. Bosch 11224 and 11222 rotary drills were fitted with shrouds which acted as local exhaust hoods when attached to a HEPA vacuum. Personal exposure levels and area samples were taken to monitor asbestos concentrations in the work area. Exposure levels were reduced to levels which were below the OSHA permissible exposure level for all combinations of drill, shroud and floor material/condition tested.
