i •1 <br /> The field team should remove their personal protective clothing <br /> in the following sequence : <br /> Step 1 : Move out of the exclusion zone <br /> nead nto the <br /> Protective <br /> decontamination zone, Do not remove personal <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 us6d 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 hydrocarbons of oa <br /> concentrations will be measured primarily by <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 /> both excavation and breathing zone concentration of 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 />
