Section 6. Health Hazard Data,continuedMedkal Conditions Aggravated by Long-Term Rxposum: Nervous. liver. kidney. or skin disorders. Target Organs: Liver. kidney, eyes.upper respiratory tract. skin, and central nervous system. primary Entry Routes: Inhalation snd skin and eye contsct. Acute Effects: Exposure tohigh levels can cause liver damage which may take several weeks to develop. Vapor exposum can cause slight smarting of the eyes and thmat (inm~ high concentrations). In human studies, exposum to 2000 ppm/5 min caused mild CNS depression: 600 ppm/lO min caused numbness around thelouth, dizziness, and incoordination; 180 ppfl hr caused mild eye. nose, and throat irritation. flushing of the face and neck, headache, somnoma,and slurred speech. Skin contact may produce dermatitis because of perchlomethylene’s defatting action (more common after repeatedexposure). Direct eye contact causes tearing and burning but no permanent damage. Ingestion is mm but can cause irritation of the lips, mouth adgastrointestinal tract irregular heartbeat nausea I% vomiting diarrhea (possibly blood stained), drowsiness. unconsciousness, and rifk of puhonaryedema (fluid in lungs). Chronic Effects: Prolonged exposure can cause impaired memory, extremity (hands, feet) weakness, peripheralneumpathies, impaired vision, muscle cramps, liver damage (fatty degeneration, necrosis, yellow jaundice, and dark urine) and kidney damage(oliguric uremia, amjesfion and granular swelling).FIRST AID Rescuers must not enter areas with potentiaUy high peddoroethykne kvek without a se&contained breathing apparatus.Eyes: Do not allow victim to tub or keep eyes tightly shut. Gently lift eyelids and flush immediately and continuously with flooding amounts ofwater until transported to an emergency medical facility. Consult a physician immediately. Skin: Quicwy remove contaminated clothing. Rinsewith flooding amounts of water for at least 15 min. Wash exposed area with soap and water. For reddened or blistered skin, consult a physician.Inhaiation: Remove exposed petson to Besh air and suppott breathing as needed Never adminirtcr u&nalinr Ingestion: Never give anything bymouth to an unconscious or convulsing person. Contact a poison control center and unless otherwise advised, have that cons&ru uad ufen persondrink 1 to 2 glasses of water. then induce vomiting. Be sure victims head is positioned to avoid aspiration of vomitus into the lungs. Note toPhysicians: Monitor level of consciousness, EEG (abnormalaties may indicate chronic toxicity), blood enyme levels (for 2 to 3 wk after exposure),EKG, adequacy of respirations & oxygenation. and liver and kidney function. BEZs: C$& io expired air (10 ppm). sample prior to last shiftof work week; C+& in blood (1 mg/L). sample prior to last shift of work week; trichlomacetic acid in urine (7 mg/L). sample at end of workweek.Section 7. Spill, Leak, and Disposal Procedures :Spill/Leak: Notify safety personnel, isolate and ventilate area. deny enlay. and stay upwind. Shut off ignition sources (although noncombustible, itforms toxic vapors from thermal decomposition). For small spills. take up with earth, sand, vermiculite, or other absorbent, noncombustiblematerial and place in suitable containers for later disposal. For large spills, dike far ahead of spill and await reclamation or disposal. Report anyrelease in excess of 1 lb. Follow applicable OSHA regulations (29 CFR 1910.120). Environmental Transport: If released to soil, perchloroethyleneevaporates and some leaches to groundwater. It may absorb slightly to soils with heavy organic matter. Biodegradation may be important inanaerobic soils. In water, it is subjecto rapid volatilization with an estimated half-life from
