Health and Safety Plan Underground Tank Program Tank Removal or Over -Excavation Resample INTRODUCTION PURPOSE ANDS CCPR The Health and Safety Plan, for underground tank removal/over-excavation provides for the protection of on-site personnel and the surrounding community during site characterization activities. The including menta, specifications and procedures presented with -the plan will apply to all personnel on-site, including emploueesT-subcontractors, site visitors and regulatory agency personnel. HAZARD ANALYSIS The most significant risk associated with petroleum contaminated soil is elposure to aromatic compounds. Skin contact will be eliminated by use of clothi hng, eye wear, and gloves and the hazard will will he.mcnimized using appropriate respiratory protective devices as determined by on-site air monitoring. The Safety Coordinator/Project Manager will establish an exclusion zone encom assin Cot radius from the work area. Access Within this zone will be limited to required personnel. To or�tnic vapors will be monitored within the exclusion zone using a photoionization d p g a Do tal calibrated for benzene, the most roxic of the aromatic hvdrocarbons. Current enforceableand (PID) recommended exposure limitations for potential site contaminants are presented in Table 1. PERSONAL PROTECTIVE EQUIPMENT A minimum of U.S. EPA level D protection will be required within the exclusion zone for any workers engaged in sample collection or other activities on this site. Level D protection will include: • Disposable Tvvek coverall (when in contact with contaminated material) • Boots with steel toe • Splash goggles or safety glasses • Chemical resistant disposal gloves (when in contact with contaminated material) Level C protection will be required if PID readings exceeding 10 pprn over background concentration are recorded in the workers' breathing zone. Level C protection will consi w • Disposable Tek coverall st of: • Boots with steel toe • Chemical resistant boot covers • C=hemical resistant disposal gloves (inner) • Chemical resistant outer gloves • MSI-L-�/;\;ICSH approved half -mask air -puri lying respirator with dual organic vapor cartridges PID readings exceeding 250 g 5 ppm in the workers' breathing zone wi=ll require work stoppage and site evacuation. An explosion -proof fan may be used to vent the work area. DECONTAMINATION During all field operations, care will be taken to minimize contact with soils ;u1d ground water. spoils and developmental water will be stored on-site for proper treatment or disposal. This will mi Drilling cunrtct and dispersion of potentially contaminated materials. ncmlze II
