TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Not combustible. Heating will cause rise in pressure with risk of bursting.
NO contact with hot surfaces.

EXPLOSION

In case of fire: keep cylinder cool by spraying with water.
EXPOSURE


Inhalation Confusion. Dizziness. Headache.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin ON CONTACT WITH LIQUID: FROSTBITE.
Cold-insulating gloves.
ON FROSTBITE: rinse with plenty of water, do NOT remove clothes.
Eyes (See Skin).
Safety goggles 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 take to a doctor.
Ingestion


SPILLAGE DISPOSAL PACKAGING & LABELLING
Ventilation. NEVER direct water jet on liquid. In case of large spillage, personal protection: complete protective clothing including self-contained breathing apparatus.

CHLOROTRIFLUOROMETHANE ICSC: 0420
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUEFIED GAS, WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
The gas is heavier than air and may accumulate in low ceiling spaces causing deficiency of oxygen.

CHEMICAL DANGERS:
The substance decomposes on burning or on contact with hot surfaces producing toxic and corrosive fumes including hydrogen chloride, hydrogen fluoride and phosgene. Incompatible with certain metal powders (aluminium, zinc, beryllium).

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: 1000 ppm, 4300 mg/m; Peak limitation category: II(8); Pregnancy risk group: IIc; (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation.

INHALATION RISK:
On loss of containment this gas can cause suffocation by lowering the oxygen content of the air in confined areas.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the cardiovascular system, resulting in impaired functions. Exposure could cause lowering of consciousness. See Notes.

PHYSICAL PROPERTIES
Boiling point: -81.4C
Melting point: -181C
Relative density (water = 1): 1.3
Solubility in water: none
Relative vapour density (air = 1): 3.6
ENVIRONMENTAL DATA
This substance may be hazardous to the environment; special attention should be given to its impact on the ozone layer.
NOTES
High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Check oxygen content before entering area. Physician should give special attention to the drugs used in treatment because of the effects of the substance on cardiac rhythm. Do NOT use in the vicinity of a fire or a hot surface, or during welding. Arcton 13, FCC 13, Freon 13, Frigen 13, Genetron 13 and Isceon 13 are trade names. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, Emergency Response.
