Do not remove personal protective equipment. <br />Step 2: Obtain decontamination solutions and decontaminate the <br />spades, shovels and other equipment by brushing them under a water <br />rinse. A high-pressure steam cleaner may also be used for <br />decontamination. All wastes and spent decontamination liquids will <br />be properly contained. <br />Step 3: Remove outer gloves and coveralls and place them inside a <br />garbage bag. Keep the air purifying respirator on. <br />Step 4: Move to the support zone and remove the respirator. <br />Monitoring Program <br />Personal exposure to ambient airborne hazards will be monitored to <br />assure that personnel exposures do not exceed acceptable limits and <br />that appropriate selection of protective equipment items is made. <br />Airborne hydrocarbon vapor concentrations will be measured primarily <br />by the use of a hydrocarbon vapor meter. If concentrations approach <br />criteria levels, all personnel will be notified of possible site <br />safety changers. Audits will be conducted by the Safety Officer to <br />insure compliance with the Safety Plan and to provide additional <br />support as required. <br />Ambient Vapor Reading <br />A hydrocarbon vapor detector will be used during drilling and <br />excavation activities. This instrument will be used to measure both <br />excavation and breathing zone concentration of hydrocarbon vapors. <br />The instrument will be calibrated on a regular schedule using known <br />calibrated gases. <br />Readings will be taken in the area where the field team members are <br />working and surrounding down -wind areas. Measurements will be taken <br />every 30 minutes where hydrocarbon vapors indicate levels above 30 <br />ppmv. All readings will be recorded in a field notebook. <br />Emergency Procedures listed in this plan are designed to give the <br />field team instruction on how to handle medical emergencies and fires <br />and explosions. The emergency procedures will be carefully reviewed <br />with the field team during the health and safety training session. <br />SSN-9 <br />
