Health and Safety Plari <br /> Underground Tank Program <br /> Tank Removal or <br /> Over-Excavation Resample <br /> INTRODUCTION <br /> PURPOSE HNU SCOFF <br /> The Health and Safety Plan, for underground tarda, removal/over- <br /> excavation, provides for the protection of on-site personnel and the <br /> surrounding community during site characterization activities. The <br /> requirements, specifications and procedures presented with this plan <br /> will apply to all personnel on-site, including employees, sub-- <br /> contractors, site visitors and regulatory agency personnel . <br /> KEY_PERSQNNEL, <br /> HAZARD ANALYSIS'_ <br /> The most significant risk associated with petroleum contaminated <br /> soil is exposure to aromatic: compounds. Skin contact will be <br /> eliminated by use of clothing, eye wear, and gloves and the <br /> inhalation hazard will be minimized using appropriate respiratory <br /> protective devices as determined by on-site air monitoring. The <br /> Safety Coordinator/Project Manager will establish an exclusion zone <br /> encompassing a 50 foot radius from the work. area. Access within <br /> this zone will be limited to required personnel . Total organic <br /> vapors will be monitored within the exclusion zone using a <br /> photoionization detector (PID) calibrated for benzene the most toxic <br /> of the aromatic hydrocarbons. Current enforceable and recommended <br /> exposure limitations for potential site contaminants are presented <br /> in Table 1. <br /> PERSONAL_PROTECTIVE._EQUIPNEN.'. <br /> A minimum Of US EPA level D protection will be required within the <br /> exclusion zone for any workers engaged in sample collection or other <br /> activities on this site. Level D protection will include: <br /> o Disposable Tyvek coverall (When in contact with <br /> contaminated material ) <br /> n Boots with steel toe <br /> o Splash goggles or safety glasses <br /> Chemical resistant disposal gloves (When in contact <br /> with contaminated material ) <br /> Level C protection will be required if PID readings exceeding 10 ppm <br /> over background concentration are recorded in the workers breathing <br /> zone. Level C protection will consist of: <br /> o Disposable Tyvek. coverall <br /> 0 Boots with steel toe <br /> o Chemical resistant boot covers <br /> o Chomical rc7rii ": Int Oi9;i0541 MY" ( inner) <br /> o Chemical resistant outer gloves <br /> n MSHA/NIOSH approved half-mask air-purifying <br /> respirator with dual organic vapor cartridges <br /> PID reading exceeding 250 ppm in the workers breathing zone will <br /> require work stoppage and site evacuation. An explosion proof <br /> fan may be used to vent the work. area. <br /> -1-- <br />
