AUG 29 '90 09',52 N.H.LWC). � P. 16/21 <br /> Page 11 <br /> 7-1 _roU:tUAjDants <br /> contaminant Fluids historically used and stored on the site are <br /> waste oil, solvent and paint/laquer thinner. <br /> Tetra Et <br /> Tetra Ethyl Tread (TEL) is a 'co,lorless, oily liquid with a <br /> characteristic musty odor. TEL is often dyed red, orange or <br /> blue. TEL has historically been added to gasoline as an <br /> anti-knock additive (leaded gasoline) . TEL is highly poisonous <br /> and will absorb into the body through the skin. Other routes of <br /> exposure include inhalation, ingestion, and injection into <br /> wounds. The OSHA Permissible Exposure Limit (PEL) for TEL is <br /> 0. 075 milligrams per cubic meter of air (mq/w3) as an eight hour <br /> time weighted average (TWA) . The American Congress of <br /> Governmental. Industrial Hygienists (ACGIH) Threshold Limit Value <br /> is 0. 1 mg/m3 as an eight hour time weighted average (TLV-TWA) . <br /> The Immediately Dangerous to Life and Health level (IDLH) for TEL <br /> is 40 mg/m3. TEL has a vapor pressure of 0. 2 millimeters Mercury <br /> (4.2 mm Hg) and a melting point range of -216 F to -202 F. The <br /> bailing point of TEL is 212 F. The flash point for TEL is 200 <br /> F. No upper and lower explosive levels (UEL and LEL) are listed <br /> in the NIOSH Pocket Guide to chemical Hazards. TEL is <br /> incompatible with strong oxidizers, sulfuryl chloride: and <br /> potassium permanganate. <br /> TEL is a suspected carcinogen. Symptoms of over-exposure include <br /> insomnia, lassitude, anxiety, muscular tremor, hyperreflexia, <br /> bradycardia, hypotension, hypothermia, skin pallor, nausea, <br /> hallucination, convulsion, coma and eye irritation. <br /> Ethylbenze.te <br /> Ethylbenzene is a colorless liquid with an aromatic odor. It has <br /> a melting point of --139 F and a boiling point of 100F. <br /> Ethylbenzene's UEL, is 6.7% ; the LET, is 1. 0%. Ethylbenzene has a <br /> flash point of 59 F. It is incompatible with strong oxidizers. <br /> Ethylbenzene has a ACGIH TLV of 100 ppm or 435 mg/m3 . <br /> Ethylbenzene has an IDLH level of 2000 ppm. Symptoms of <br /> over-exposure include irritated eyes, irritation of the mucous <br /> membrane, headache, dermatitis, narcolepsy and coma. <br />
