solution for a minimum of 15 minutes. Ingestion warrants immediate <br /> medical attention. <br /> 4.1.1.4 Heavy Waste Oils <br /> Heavy waste oils, including lubricants, grease, and used motor and <br /> hydraulic fluids, have been shown to cause skin cancer during prolonged <br /> dermal exposure in laboratory animals. Therefore, dermal protection <br /> must be provided when contact with used oil is suspected. Contaminated <br /> skin should be washed as soon as possible. <br /> 4.1.1.5 Benzene <br /> Benzene is a known human carcinogen that can cause leukemia via <br /> chronic exposure. It is a severe eye and moderate skin irritant. Human <br /> effects by inhalation and ingestion include: euphoria, changes in sleep <br /> and motor activity, nausea and vomiting, other blood effects, dermatitis <br /> and fever. In industry, inhalation is the primary route of chronic benzene <br /> poisoning. Poisoning by skin contact has also been reported. Although <br /> the current Cal/OSHA PEL for benzene is 1 ppm, recent research (1987) <br /> indicates that effects are seen at less than 1 ppm over extended periods. <br /> The STEL for benzene is 5 ppm. <br /> 4.1.1.6 Toluene <br /> Human systemic effects of exposure to toluene include: central nervous <br /> system changes, hallucinations or distorted perceptions, motor activity <br /> changes, psychophysiological changes and bone marrow changes. It is a <br /> severe eye irritant and an experimental teratogen. The current Cal/OSHA <br /> PEL for toluene is listed as 50 ppm and the STEL is 150 ppm. <br /> 4.1.1.7 Ethylbenzene <br /> Ethylbenzene is mildly toxic by inhalation and skin contact. Inhalation <br /> can cause eye, sleep and pulmonary changes. It is an eye and skin irritant <br /> at levels as low as 0.1% (1,000 ppm) of the vapor in air. At higher <br /> concentrations, it is extremely irritating at first, and can then cause <br /> dizziness, irritation of the nose and throat, and a sense of constriction in <br /> the chest. The current Cal/OSHA PEL is listed as 100 ppm and the STEL <br /> is 125 ppm. <br /> 4.1.1.5 Xylene <br /> Xylene exhibits the general chlorinated hydrocarbon central nervous <br /> system effects and olfactory (smell) changes, eye irritation, and pulmonary <br /> changes. It is a severe skin irritant, starting at levels of 200 ppm. The <br /> 5164.00-3/4/03 <br /> ERM <br /> HASP CANON 8 <br />
