i Y Health and Safety Plan Underground Tank Program 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 of on-site personnel and the surrounding community during site characterization activities. The requirements, specifications and procedures presented with -the plan will apply to al] personnel on-site, including emplo.vee-srsubcontractors, 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 aur monitoring. The Safety Coordinator/Project Manager will establish an exclusion zone encompassing a 50- toot radius from the work area. Access Within this zone will be limited to required'personnel. Total organic vapors will be monitored within the exclusion zone using a photo ionization detector (PID) alibrated Cor benzene, the most toxic of the aromatic hydrocarbons. Current enforceable and recommended exposure limitations for potential site contaminants are presented in Table 1. PERSONAL PROTECTDM E QT JTPMENT minimum oC 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 Twek coverall (when in contactwith contaminated material) • Boots with steel toe • Splash goggles or safety glasses • Chemical resistvit disposal gloves (when in contact with contaminated material) i 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 Tvvek coverall l • Boots with steel toe {, • Chemical resistant boot covers • Chemical resistant disposal gloves (inner) • Chemical resistant outer gloves ViSK1/NIC)SH approved ha1F-mask air-purifying respirator with dual organic vapor cartridges PID readings exceeding250 site evacuation.
