It is important that personal protective equipment and safety requirements be appropriate to protect against the potential hazards at the site. Protective equipment will be selected based on the contaminant type(s), concentration(s), and routes of entry. In situations where the type of materials and possibilities of contact are unknown or the hazards are not clearly identifiable, a more subjective determination must be made of the personal protective equipment. Field personnel and visitors are required to wear the following clothing and equipment, as a minimum, while on the Pacific Gas & Electric Company—Las Vinas Dehydrator Station Sandblast Residue Removal Project. a. Hard Hat b. Safety Glasses C. Hearing Protection li 2. Required Protection All personnel will wear safety glasses,hard hats, steel toe rubber boots,tyvek suits, and impermeable gloves when operating in the work zone. All personnel will also wear air-purifying respirators with organic vapor cartridges and dust pre- ` ' filters. All excavation will cease, the equipment will be shut down, and personnel will withdraw from the area if either(1) The airborne concentrations exceed The American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Values (TLV's) TLV-TWA of 0.05 mg/m3 or(2) the airborne concentrations exceed the California Occupational Safety and Health Administration (CAL/OSHA) Permissible Exposure Limits (PEL's) PEL-TWA of 0.05 mg/m3. The Site Safety and Health Officer will determine when personnel may return to the work area. If work proceeds in an environment where lead contaminated aerosol concentrations exceed the above TLV's and PEL's, a self- contained breathing apparatus or the personnel will utilize an airline respirator. Work will be terminated in an environment where oxygen concentrations fall below 19.5 percent, where cartridge respirators are in use. B: Exposure Monitoring Plan 1. General An air quality-monitoring program may be implemented to provide baseline and on-going air quality data for site operations. The program will include: a. Air monitoring will be done during any impacted material excavation whenever the presence of lead contaminated aerosols is expected.
