Acute Health Hazards

THRESHOLD LIMIT VALUE 50 PPM TWA-8 hour (ACGIH) EFFECTS OF OVEREXPOSURE Acute Excessive inhalation may produce symptoms of central nervous system depression ranging from light-headedness to unconsciousness and death. Ingestion may produce gastrointestinal irritation with nausea, vomiting, stomach cramps and diarrhea. Exposure of eyes and skin may produce irritation. Chronic Can cause headache, mental confusion, depression, fatigue, loss of appetite, nausea, vomiting, cough,loss of sense of balance and vision disturbances. Chronic overexposure to Trichloroethylene has caused toxic effects in the liver, lymphatic, kidney and cardiovascular system of laboratory animals. Humans exposed to Trichloroethylene can become intolerant to Ethyl Alcohol, with small quantities causing inebriation and skin blotches.

Principle Routes of Exposure

Inhalation Skin Major route of potential exposure. Depresses the central nervous system. Symptoms of overexposure include headache, nausea, vomiting, dizziness, vertigo, fatigue, lightheadedness and coughing. Absorption of liquid through intact skin is a possible but unlikely route of significant exposure. Prolonged or repeated contact may cause irritation, defatting of skin, and dermatitis. Eyes Liquid may cause pain, and slight temporary injury to eyes. Vapors can irritate eyes. Ingestion Single dose toxicity low to moderate. If vomiting occurs, Trichloroethylene can be aspirated into lungs, which can cause chemical pneumonia and systemic effects.

Medical Conditions Generally Aggravated by Exposure

Acute and chronic liver and kidney disease, rhythm disorders of the heart, neuritis and other nervous system disorders. Carcinogenicity The International Agency for Research on Cancer (IARC) has concluded that there is sufficient evidence for the carcinogenicity of Trichloroethylene to experimental animals, and limited evidence for the carcinogenicity of Trichloroethylene to humans, resulting in a classification in Group 2A as a substance probably carcinogenic to humans. The ACGIH has classified Trichloroethylene in category A5 as an agent not suspected as a human
