**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Toxic by inhalation, in contact with skin and if swallowed. Limited
evidence of a carcinogenic effect. Dangerous for the ozone layer.
Toxic : danger of serious damage to health by prolonged exposure
through inhalation. Harmful to aquatic organisms, may cause long-term
adverse effects in the aquatic environment.Cancer suspect agent.
Potential Health Effects
Eye:
Causes eye irritation. Vapors cause eye irritation.
Skin:
Causes skin irritation. May be absorbed through the skin in harmful
amounts. Contact with the skin defats the skin.
Ingestion:
May cause liver and kidney damage. May cause central nervous system
depression, characterized by excitement, followed by headache,
dizziness, drowsiness, and nausea. Advanced stages may cause
collapse, unconsciousness, coma and possible death due to respiratory
failure. Substance is a hepatotoxin and is capable of producing a
toxic effect on the liver.
Inhalation:
May cause liver and kidney damage. Exposure produces central nervous
system depression. May be harmful if inhaled.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. Chronic
ingestion may cause effects similar to those of acute ingestion. May
cause liver and kidney damage. May cause cancer according to animal
studies. Chronic exposure may cause visual disturbances. Carbon
tetrachloride is a CNS depressant.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid.
Skin:
In case of contact, immediately flush skin with plenty of water for
at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
Ingestion:
Potential for aspiration if swallowed. Get medical aid immediately.
Do not induce vomiting unless directed to do so by medical
personnel. Never give anything by mouth to an unconscious person.
Inhalation:
POISON material. If inhaled, get medical aid immediately. Remove
victim to fresh air. If not breathing, give artificial respiration.
If breathing is difficult, give oxygen.
Notes to Physician:
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Material will not burn. Use water spray to keep
fire-exposed containers cool. Containers may explode in the heat of a
fire. Non-combustible, substance itself does not burn but may
decompose upon heating to produce corrosive and/or toxic fumes.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Avoid runoff into storm sewers and
ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Isolate
area and deny entry. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Avoid contact with eyes, skin, and clothing. Keep
container tightly closed. Do not breathe vapor. Use only with
adequate ventilation.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits. Use only under a chemical fume hood.

Carbon tetrachloride is harmful to the liver and a CNS depressant
following short-term inhalation, skin contact or ingestion. The liver
effects have been observed at concentrations lower than those
required to produce CNS effects. Two reviews indicate that ingestion
of 14-20 ml or 50-150 ml could be fatal. Although, 1.5 ml (34 mg/kg)
has caused death in a few cases.
