REGEIVEL • Y Health and. Safety Ilan MAR 0 2 2016 Underground Tank E�VI�(�� NTAL Program .T n�4a�Tas� Tank Removal or Over-Excavation Resample INTRODUCTION PURPOSE AND SCOPE The Health and Safety Plan, for underground tank removal/over-excavation provides for the protection or on-site personnel and the surrounding community during site characterization activities. The requirements, specifications -and procedures presented with the plan will apply to all personnel on-site Including emplo.ueesrsubcontractors, site visitors and regulatory agency personnel. HAZARD ANALYSIS The most significant risk associated with petroleum contaminated soil is exposure to aromatic compounds. Skin contact will be eliminated by use OF clothing, eye wear, and gloves and the inhalation hazard will be minimized using appropriate respiratory protective devices as determined by on-site ;tor monitoring. Tl�e Safety Coordinator/Project Manager will establish an exclusion zone encompassin a ��)_ Coot radius from the work area. Access Within this zone will be limited to required personnel. Total orguncc vapors will be monitored within the exclusion zone usinga photolonlzar,on detector (PID) calibrated for benzene, the most toxic of the aromatic hydrocarbons. Current enforceable and recommended exposure limitations for potential site contaminants are presented in Table 1. PERSONAL PROTECTIVE' E IPMENT _'i 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 Tyvek 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 protecrion will be required if PID readings exceeding 10 concentration are recorded in the workers' breathing zone. Level C PPm over background protection will consist of. • Disposable Twek coverall ZZ, • Boots with steel toe • Chemical resistant hoot covers • Chemical resistant disposal gloves (inner) • Chemical resistanr outer gloves • NISI-L-VNIOSH approved half-mask air-purifying respirator with dual organic vapor cartridges PID readings p ,s exceeding 250 ppm in the workers' breathing zone will require work stoppage and sire evacuation. An explosion-proof fan may be used to vent the work area. D E CO NTAM I NATI O N Dunn);til held operations, care will be taken to minimize contact with soils and around water. Drilling spoils and developmental water will be stored on-sire for proper treatment or disposal. This will m .� conracr ;tnd dispersion of potentially contaminated materials. ii ' Inlmcze
