Site Safety and Health Plan l�erracon <br /> ±19.41 Acres Vacant Land ■ Manteca, California <br /> June 12, 2017 ■ Terracon Project No. NB177049 <br /> Gasoline is irritating to the skin, eyes and mucous membranes. Dermatitis may result from <br /> prolonged contact with the liquid. Gasoline acts as a central nervous system depressant. <br /> Exposure may cause staggering gait, slurred speech and mental confusion. Gasoline exposure <br /> may affect the liver, kidneys and spleen. Absorption of alkyl lead antiknock compounds contained <br /> in many gasolines poses an additional health concern, especially where there is prolonged skin <br /> contact. <br /> DIESEL FUEL (No. 2-D) <br /> Permissible Exposure Limit <br /> 100 mg/m3 ppm ACG IH TLV (As mist/vapor) <br /> Diesel fuel is a skin and mucous membrane irritant and a central nervous system depressant. <br /> Poisoning may affect the liver and kidneys. Skin contact may result in drying and cracking of the <br /> skin. <br /> FUEL OIL (No. 6) <br /> Permissible Exposure Limit <br /> 400 ppm OSHA PEL (as petroleum distillates/naphtha) <br /> 0.2 mg/m3 OSHA PEL (Coal Tar Pitch Volatiles, "PNA's") <br /> Fuel oil No. 6, or "Bunker Fuel", is of low volatility. It can be irritating to the eyes and skin. This <br /> substance is likely to contain polynuclear aromatic hydrocarbons (PNA's), some of which are <br /> considered carcinogenic. PNA's present a skin contact hazard. Avoid skin contact with potentially <br /> contaminated site materials. <br /> BENZENE <br /> Permissible Exposure Limit <br /> 1 ppm OSHA PEL <br /> 5 ppm OSHA 15 min STEL <br /> 0.5 ppm OSHA Action Level <br /> Benzene is a central nervous system depressant and an eye and skin irritant. Poisoning may <br /> cause hemorrhages and immunosuppression. A relationship has been discovered between <br /> benzene exposure and leukemia. Benzene is regulated as an occupational carcinogen. Acute <br /> exposure may cause dizziness, excitation, weakness, headache, giddiness, breathlessness and <br /> chest constriction. <br /> TOLUENE <br /> Permissible Exposure Limit <br /> 20 ppm ACGIH TLV <br /> (Skin Absorbable) <br /> 7 <br />
