I <br /> The field team should remove their personal protective clothing <br /> in the following sequence : <br /> Step 1 : Move out of the exclusion zone and into the <br /> decontamination zone . Do not remove personal protective <br /> equipment. <br /> Step 2 : Obtain decontamination solutions and decontaminate the <br /> spades , shovels and other equipment by brushing them under a <br /> water rinse . A high-pressure steam cleaner may also be uso& for <br /> decontamination, All wastes and spent decontamination liquids <br /> will be properly contained. <br /> Step 3 : Remove outer gloves and coveralls and place them inside <br /> a 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 <br /> monitored to assure that personnel exposures do not exceed <br /> acceptable limits and that appropriate selection of protective <br /> equipment items is made . Airborne hydrocarbon vapor <br /> concentrations will be measured primarily by the use of a <br /> hydrocarbon vapor meter . If concentrations approach criteria <br /> levels , all personnel will be notified of possible site safety <br /> changers . Audits will be conducted by the Safety officer to <br /> insure compliance with the Safety Plan and to provide <br /> additional 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 <br /> zone concentration of <br /> both excavation and breathing . hydrocarbon <br /> vapors , the instrument will be calibrated on a regular <br /> schedule using known calibrated gases , <br /> Readings will be taken in the area where the field team members <br /> are working and surrounding down-wind areas . Measurements will <br /> be taken every 30 minutes where hydrocarbon vapors indicate <br /> levels above 30 ppmv. All readings will be recorded in a field <br /> notebook. <br /> Emergency Procedures listed in this plan are designed to give <br /> the field team instruction on how to handle medical emergencies <br /> and fires and explosions . The emergency procedures will be <br /> carefully reviewed with the field team during the health and <br /> safety training session , <br />
