  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.        In case of fire in the surroundings, use appropriate extinguishing media.  In case of fire: keep drums, etc., cool by spraying with water. 

 AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS PREVENTION FIRST AID
Inhalation Headache. Nausea. Vomiting. Dizziness. Drowsiness.  Use ventilation, local exhaust or breathing protection.  Remove immediately from exposure. Fresh air, rest. Artificial respiration may be needed. Refer immediately for medical attention. 
Skin MAY BE ABSORBED! Redness. Further see Inhalation.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer immediately for medical attention. 
Eyes Redness. Pain.  Wear face shield or eye protection in combination with breathing protection.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Burning sensation in the stomach. Abdominal pain. Diarrhoea. Further see Inhalation.  Do not eat, drink, or smoke during work.  Rinse mouth. Refer immediately for medical attention. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Collect leaking and spilled liquid in covered containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.

CARBON TETRACHLORIDE ICSC: 0024
PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
The vapour is heavier than air. 

Chemical dangers
Decomposes on contact with hot surfaces or flames. This produces toxic and corrosive fumes of hydrogen chloride (see ICSC 0163), chlorine (see ICSC 0126) and phosgene (see ICSC 0007). Reacts with some metals such as aluminium, magnesium and zinc. This generates fire and explosion hazard.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation, through the skin and by ingestion. 

Effects of short-term exposure
The substance is irritating to the eyes. The substance may cause effects on the liver, kidneys and central nervous system. This may result in unconsciousness. Medical observation is indicated. 

Inhalation risk
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the liver and kidneys. This may result in impaired functions of organs and cirrhosis. This substance is possibly carcinogenic to humans. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: 5 ppm as TWA; 10 ppm as STEL; (skin); A2 (suspected human carcinogen).
MAK: 3.2 mg/m3, 0.5 ppm; peak limitation category: II(2); skin absorption (H); carcinogen category: 4; pregnancy risk group: C.
EU-OEL: 6.4 mg/m3, 1 ppm as TWA; 32 mg/m3, 5 ppm as STEL; (skin) 

ENVIRONMENT
It is strongly advised not to let the chemical enter into the environment. The substance is harmful to aquatic organisms. The substance may cause long-term effects in the aquatic environment. Avoid release to the environment because of its impact on the ozone layer. 

NOTES
Use of alcoholic beverages enhances the harmful effect.
Depending on the degree of exposure, periodic medical examination is suggested.
The odour warning when the exposure limit value is exceeded is insufficient.
Do NOT use in the vicinity of a fire or a hot surface, or during welding.
