Fire and Explosion Data Flash Point: None reportedj Autoignition Temperature: None reported , LEL: None reported______UEL: None reported Extinguishing Media: Carbon tetrachloride is nonflammable and will not support combustion. Use extinguishing media appropriate to the surrounding fire. This material was previously used as an extinguishing medium in portable fire extinguishers, but its toxicity and fire decomposi tion products lead to its replacement with "safer" extinguishing media. Unusual Fire or Explosion Hazards: Carbon tetrachloride can react violently with hot or burning metals such as aluminum and magnesium. Special Fire-fighting Procedures: Since fire may produce toxic fumes, wear a self-contained breathing apparatus (SCBA) with a full facepiece operated in the pressure-demand or positive-pressure mode and frilly encapsulating suit Use water spray to cool fire-exposed containers. Be aware of runoff from fire control methods. Do not release to sewers or waterways. Section 5. Reactivity Data Stability/Polymerization: Carbon tetrachloride is stable at room temperature in closed containers under normal storage and handling conditions. Hazardous polymerization cannot occur. Chemical Incompatibilities: Carbon tetrachloride reacts violently with fluorine gas, alkali metals, and aluminum (see reference 126 for specific incompatibilities). Conditions to Avoid: This material has caused explosions when used as a fire exunguisher on wax fires and uranium fires. It may also form toxic phosgene when used to put out electrical fires. Hazardous Products of Decomposition: Thermal oxidauve decomposition of carbon tetrachloride can produce toxic phosgene and hydrogen chloride.

Health Hazard Data Carcinogenicity: The NTP, 1ARC, and ACCIH list carbon tetrachloride as an anticipated human carcinogen, a possible human carcinogen, and a suspected human carcinogen, respecuvely. Summary of Risks: Carbon tetrachloride is highly toxic and irritating by inhalation, ingestion /mean lethal dose is 5 to 10 ml), and skin absorp tion. Alcohol's svnergisuc effects markedly increase CC1,'s toxicity. Excessive exposure may result in central nervous system depression, cardiac arrhythmias, and gastrointesunai symptoms. In humans the majority of fatalities have been the result of renal injury with secondary cardiac failure. Kidney and liver damage can occur from severe acute or chronic exposure. Human liver damage occurs more often after ingestion of the liquid than after the inhalation of the vapor. However, after a 30 min to 1 hr exposure to concentrations of 1000 to 2000 ppm, humans have died from acute renal damage. Medical Conditions Aggravated by Long-Term Exposure: Prolonged recovery and permanent disability of the liver, kidney, and lungs ate oosstble. Target Organs: Central nervous system, eyes, skin, liver, kidneys, lungs. Primary Entry Routes: Inhalation, percutaneous (through the skin). Acute Effects: Acute exposure symptoms include eye, nose, skin, and throat irritation; cough, dyspnea, cyanosis, cardiac arrhythmias, headaches, dizziness, mental confusion, nausea, vomiting, abdominal pain, and diarrhea. Jaundice and abnormal liver enlargement accompanied by oliguna (reduced excretion of urine), proteinuria (protein m mine), and hematuria (blood in unne) may occur even after several days delay. Chronic Effects: Chronic exposure symptoms include defatting dermatitis, headaches, dizziness, mental confusion, apathy, anorexia, nausea, vomiting, abdominal pain, weight loss, narrowing of visual field, opuc nerve damage with possible blindness, hearing loss, and renal and hepatic decompensation (loss of these organs' ability to correct dvsfuncuon). Chrome exposure may result m the development of aplastic anemia. FIRST AID Eves: Flush immediately, including under the eyelids, gently but thoroughly with flooding amounts of running water for at least 13 min. Skin: Quickly remove contaminated clothing. After rinsing affected skin with flooding amounts of water, wash it with soap and water. Inhalation: Remove exposed person to fresh air and support breathing as needed. Ingestion: Never give anything by mouth to an unconscious or convulsing person. Give one to two glasses of water to dilute and induce vomiting, unless the person shows evidence of decreasing mental functioning and awareness. After first aid, get appropriate in-plant, paramedic, or community medical support. Physician's Note: To minimize hepatorenal damage, consider intravenous acetylcvsteioe. Hvperbaric oxygen is also utilized for significant expo sures. Dialysis has also been suggested in severe cases. Give cardiorespiratory support as indicated and carefully monitor fluid and electrolytes. Closely monitor hepatic and renal functions. Avoid epinepnnne because of myocardial sensitization and potential for inducing ventricular ' imvthymias.. ______ ___ * Section 7. Spill, Leak, and Disposal Procedures________ ____________________________ Spill/Leak: Notify safety personnel, evacuate area, and provide maximum exhaust ventilation. Cleanup personnel should protect against inhala tion and skin and eye contact. Small spills can ne absorned on paper or some noncombustible, inert ingredient and allowed to evaporate in a hood. For large spills, dike far ahead io contain spill for disposal. Prevent release of CC1, to surface water or sewers. Follow applicable OSHA regula tions (29 CFR 1910.120). Disposal: Contact your supplier or a licensed contractor for detailed recommendauons. Follow applicable Federal, state, and local regulations.

Special Protection Data__________________ Goggles: Wear protective eyeglasses or chemical safetv goggles, per OSHA eye- and face-protection regulations (29 CFR 1910.133). Respirator: Follow OSHA respirator regulations (29 CFR 1910.134) and. if necessary, wear a NIOSH-approved respirator. For emergency or nonrouune operations (cleaning spills, reactor vessels, or storage tanks), wear an SCBA. Warning: Air-punfying respirators do not protect workers in oxygen-deficient atmospheres. Other: Wear impervious gloves, boots, aprons, and gauntlets to prevent skin contact. Polyvmvl alcohol protective gear is recommended. Ventilation: Provide general and local explosion-proof venulanon systems to maintain airborne concentrations below the OSHA PEL, ACGIH TLV, and NIOSH REL (Sec. 2). Local exhaust ventilation is preferred since it prevents contaminant dispersion into the work area by controlling it at its source.(l(n, Safety Stations: Make available in the work area emergency eyewash stations, safety/quick-drench showers, and washing facilities. Contaminated Equipment: Never wear contact lenses in the work area: soft lenses may absorb, and all lenses concentrate, irritants. Remove this material from tout shoes and equipment. Launder contaminated clothing before wearing. Comments: Never eat, drink, or smoke in work areas. Practice good personal hygiene after using this material, especially before eating, drinking, smoking, using the toilet, or applying cosmetics.________________________________ Section 9. Special Precautions and Comments______________ , Storage Requirements: Store in tightly closed container in a cool, dry, well-ventilated, low fire-risk area away from incompatible materials (Sec. 5), direct sunlight, and heat. Prevent exposure of vapors to high temperature to prevent decomposition to toxic and corrosive gases and vapors. Engineering Controls: Avoid vapor inhalation and skin or eye contact. Use only with adequate ventilation and appropriate personal protective gear. Monitor vapor levels and institute a respiratory protection program which includes training, maintenance, inspection, and evaluation. Practice good personal hygiene procedures. When possible, substitute a leu hazardous solvent for CC14. Provide preplacement and biannual medical exams, including studies of liver and kidney function. Prevent exposing individuals with liver, kidney, or central nervous system diseases, or alcoholism. Alcohol's synergistic effects markedly increase CCl/s toxicity.
