1,1,1-Trichloroethane (1,1,1-TCA). 1,1,1-TCA is moderately toxic by inhalation and skin contact. It is a skin irritant and can cause central nervous system effects such as hallucinations or distorted perceptions, motor activity changes, irritability, and aggression. Gastrointestinal changes such as diarrhea, nausea, or vomiting have also been reported from 1,1,1-TCA exposure at high concentrations. The current Cal/OSHA PEL is listed as 350 ppm. Trichloroethylene (TCE). TCE is a mildly toxic VOC that is also an experimental carcinogen, tumorigen, and teratogen. It can cause eye effects, hallucinations and distorted perceptions when inhaled. TCE is an eye and severe skin irritant. Inhalation can cause narcosis, headaches and drowsiness. Chronic exposure can cause liver and other organ damage. The current Cal/OSHA PEL for TCE is listed as 50 ppm. Tetrachloroethylene (PCE). PCE is a clear, non-flammable, VOC with an etheral odor. Its major uses include commercial dry cleaning and metal degreasing. Exposure to PCE can result in effects on the central nervous system, mucous membranes, eyes, lungs, liver, kidney, heart, and skin. The most frequent effects include unconsciousness, dizziness, headache, and light-headedness. Skin contact may create a dry, scaly, itchy dermatitis. Recent studies suggest that PCE can cause liver cancer in rats and mice. The current Cal/OSHA PEL is listed as 25 ppm. It is a non- flammable liquid with a MW of 166, MP of-22°C, and a BP of 121°C. Vinyl Chloride. Vinyl chloride is a known human carcinogen which causes liver and blood tumors. It is a poison by inhalation. It is also a severe skin and eye irritant and can cause skin burns by rapid evaporation and consequent freezing. Chronic exposure has also shown liver injury. The current Cal/OSHA PEL is listed as 1 ppm due to its known carcinogenicity. Aromatic Volatile Organic Compounds Benzene. Benzene is a known human carcinogen that can cause leukemia via chronic exposure. It is a severe eye and moderate skin irritant. Human effects by inhalation and ingestion include: euphoria, changes in sleep and motor activity, nausea and vomiting, other blood effects, dermatitis and fever. In industry, inhalation is the primary route of chronic benzene poisoning. Poisoning by skin contact has also been reported. Although the current Cal/OSHA PEL for benzene is 1 ppm, recent research (1987) indicates that effects are seen at less than 1 ppm over extended periods. 4-2
