V. HAZARD ANALYSIS Jobsite Safety Analysis Forms will be filled out daily to identify potential hazards. "Hot Work" or"Permit to Work" Forms will be used to identify medium to high risk activities to include: 1. Hot work to include cutting, grinding, welding. 2. Rigging and hoisting 3. Excavation r 4. Confined space entry 5. Lockout/Tagout 6. Barricading and work area Isolation. 7. Working over 6' high Note: Any work over 6' high requires fall protection or power lift. Scissor lift requires Hot Work Permit. The use of a boom lift does not require a hot work permit. The use of an A frame ladder above 6' and properly tied off is permitted only for vent capping without a hot work permit. The JSA identifies potential hazards that pertain to specific on site activities. These activities include: The potential hazards to personnel working at the subject site have been identified as chemical contamination,physical hazards of working around heavy equipment, and heat stress (potential for cold stress due to seasonal changes). Each potential hazard relative to potential for exposure is described below. VI. CHEMICAL CONTAMINATION The chemical contaminants of concern for this project are gasoline constituents [benzene, ethyl benzene, toluene, and xylene (BETX)], The hazards associated with these chemicals are potential for fire and explosion, and potential worker exposure due to direct contact and/or inhalation of vapors of gasoline constituents. These potential hazards will be controlled through monitoring and the use of protective equipment as described later in this SSHP. Gasoline vapors (50 to 100 octane) are moderately to highly toxic via inhalation, which can cause central nervous system depression, pneumonitis, fatal pulmonary edema, and some addiction if exposures too the vapors are greater than 300 parts per million (ppm). Gasoline also poses fire and
