Anheuser-Busch/Arch Road <br /> Site Safety Plan <br /> February 11, 1992 <br /> Toluene <br /> Inhalation exposure to toluene vapor can produce effects such as <br /> central nervous system depression. Depending on exposure factors <br /> signs and symptoms can include headache, dizziness, fatigue, <br /> muscular weakness, incoordination, drowsiness, collapse and possible <br /> coma. Toluene can be a skin and mucous membrane irritant and <br /> studies have shown that high levels of toluene exposure can cause <br /> liver and kidney damage. <br /> Ethyl benzene <br /> Exposure to ethyl benzene at high vapor concentrations may produce <br /> irritation to the skin, eyes and upper respiratory tract. <br /> Overexposure to ethyl benzene vapors can produce central nervous <br /> system depression with symptoms of headache, nausea, dizziness, <br /> shortness of breath and unsteadiness. Prolonged skin exposure to <br /> ethyl benzene may result in drying and cracking of the skin <br /> (dermatitis) . Solvent resistant gloves should be worn during <br /> sampling to prevent exposure to the skin. <br /> Xylenes <br /> Depending on exposure factors, inhalation exposure to xylene vapor <br /> may produce central nervous system excitation followed by <br /> depression. Exposure to xylene vapor can produce dizziness, <br /> staggering, drowsiness and unconsciousness. At very high <br /> concentrations, xylene vapor may produce lung irritation, nausea, <br /> vomiting and abdominal pain. Xylene is not known to possess the <br /> chronic bone marrow toxicity of benzene, but liver enlargement and <br /> nerve-cell damage have been noted from chronic overexposure. <br /> 8.0 GAS/VAPOR MONITORINGS PROCEDURES <br /> The greatest potential hazards to safety and health at this site are: <br /> 1. Exposure to chemical vapors - through inhalation <br /> 2. Exposure to chemical contamination - through skin contact and <br /> ingestion. <br /> Ongoing air monitoring during project tasks will provide data to ensure <br /> that vapor concentrations are within acceptable ranges and will provide <br /> adequate selection criteria for respiratory and dermal protection. <br /> 8.0.1 A half face NIOSH approved air-purifying respirator with <br /> organic vapor cartridges must be worn by all site workers <br /> within any area where monitoring results exceed 50 ppm, and a <br /> full face respirator equipped with organic vapor cartridges <br /> must be worn by all site workers within any area where <br /> monitoring results exceed 100 ppm. <br /> 16 <br />
