B. SITE/WASTE CHARACTERISTICS <br /> Waste Type(s): Solid: XXX Sludge: Liquid: Gas: <br /> Characteristics: HYDROCARBON RESIDUALS,TOXIC <br /> Site Parameter: <br /> A MINIMUM BOUNDARY OF THREE FEET SURROUNDING THE BORINGS IS <br /> TO BE MAINTAINED IN AS MUCH AS IS POSSIBLE. <br /> C. HAZARD EVALUATION <br /> CHEMICAL HAZARDS <br /> Potential chemical hazards include skin and eye contact or inhalation <br /> exposure to potentially toxic concentrations of hydrocarbon vapors. The <br /> potential toxic compounds that may exist at the site are listed below, <br /> with descriptions of specific health effects of each. The list includes the <br /> primary potential toxic constituents of gasoline and diesel known to be <br /> on site. Exposure levels and symptoms are taken from the NIOSH Pocket <br /> Guide to Chemical Hazards. <br /> 1. BENZENE <br /> a. Colorless, clear, highly flammable liquid with characteristic odor. <br /> b. High exposure levels may cause acute restlessness, convulsions, <br /> depression, respiratory failure. BENZENE IS A KNOWN CARCINOGEN. <br /> c. Permissible exposure level (PEL) for a time weighted average (TWA) <br /> over an eight hour period is 1.0 ppm. <br /> 2. TOLUENE <br /> a. Colorless liquid with a benzene-like odor. <br /> b. High exposure levels may cause fatigue, euphoria, confusion, <br /> dizziness. TOLUENE IS LESS TOXIC THEN BENZENE. <br /> c. PEL for a ten hour TWA is 100 ppm. <br /> 3. XYLENE <br /> a. Colorless, flammable liquid with aromatic odors. <br /> b. high exposure levels may case dizziness, drowsiness, narcosis. <br /> c. PEL for a ten hour TWA is 100 ppm. <br /> Tracy Health & Safety Plan - June 1998 <br /> -2- <br />
