Health and Safety Plan Underground Tank Program Tank Removal or RECEIVED Over-Excavation Resample MAR 10 2016 INTRODUCTION ENVIRONMENTAL EMPO E ID SCOPE HC.6!Tu n006OTA917AIT 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 on requirements, specifications and procedures presented with the plan grill apply to all personnel on-sire, including employees-subcontractors, site visitors and regulatory agency personnel. HAZARD ANALYSIS The most significant risk associated with petroleum contaminated soil is exposure to aromatic compounds. Skin contract 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 air monitoring. The Safety Coordinator/Project Manager will establish an exclusc toot radius from the work area. Access Within thiion zone enompassin a 50_ s zone will be limited to required personnel. Total organic vapors will be monitored within the exclusion zone usin4a photoionization 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. PER ONAL PROTFrr" Oi1rP _4, 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 protection will be required if PID readings exceeding 10 ppm over background concentration are recorded in the workers' breathing zone. Level C protection will consist of: • Disposable Tyvek coverall • Boots with steel toe • Chemical resistant boot covers • Chemical resistant disposal gloves (inner) • Chemical resistanr outer gloves • NISK1/NIOSH approved half-mask air-purifying respirator with dual organic vapor cartridges PID readings exceeding 250 g 5 ppm in the workers' breathing zone will require work stoppage and . site evacuation. An explosion-proof fan may be used to vent the work area. D E CO NTAMINATI O N During;ill held operations, care will be taken to minimize convict with soils and ground water.
