ISan Joaquin Motor Pool Facility Health and Safety Plan • I Various hydrocarbons are usual contaminants at fuel dispensing facilities. In general, hydrocarbons and halogenated hydrocarbon exposures will typically result in signs of central nervous system disturbances While the degree of disturbance vanes with each I compound, common symptoms of exposure are disorientation, euphoria, giddiness, and confusion Most hydrocarbons are also very lipid soluble, which enables them to penetrate the skin easily, and can result in potential dermatitis conditions Benzene is a colorless liquid with an aromatic odor and is considered a human carcinogen Exposure to benzene can result in the irritation of the eyes, nose, and I respiratory system Prolonged exposure can result in giddiness, headache and lassitude Dermal exposure can result in a dermatitis condition Benzene is used in this HSP as a chemical of concern because of its known toxicity Protecting a worker against benzene exposure should be considered conservative 4.2 Physical Hazards I Hazards associated with site investigation activities most commonly are generated with the operation of heavy machinery, which produces elevated levels of noise, and may . induce dust into the surrounding air To reduce the risk of noise during excavation operations, field personnel will wear acoustic earmuffs or earplugs Should dust pose a hazard, toxic dust masks are to be worn Additionally, the following procedures will be followed during sampling. Each boring locale is to be inspected for hazards before the ' drilling begins, personnel, other than the operator and his helpers, are to stay clear of the excavation and excavating equipment, all equipment will be in good and operable condition--malfunctioning equipment will not be used, or the operation will be stopped for repair of equipment Other physical hazards that could be encountered with these works are falls, splashes of fluids, utility lines and heat and cold exposure Personnel must be aware of on-site sources for falls produced by equipment and terrain, and perform their tasks with care for these conditions Personnel can protect themselves from splashes and spills of fluids by rwearing chemically resistant gloves, coveralls, and goggles Both above and below ground utility lines pose safety hazards to personnel and equipment All equipment utilizing masts or booms must maintain at least 10 feet of clearance from overhead lines The presence of any buried utility lines at locales, both I on- and off-site, must be identified prior to commencing work Off-site buried lines can be found via Underground Service Alert at (800) 422-4133 The client must provide all information, and assume the responsibility, for clearing on-site work locales of buried lines r5
