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. Gives off irritating or toxic fumes (or gases) in a fire.

In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION

In case of fire: keep cylinder cool by spraying with water.
EXPOSURE
AVOID EXPOSURE OF (PREGNANT) WOMEN!

 •INHALATION Unconsciousness. Suffocation. (See Notes).
Ventilation.
Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
 •SKIN ON CONTACT WITH LIQUID: FROSTBITE.
Cold-insulating gloves.
ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention.
 •EYES See Skin.
Safety goggles, 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
Do not eat, drink, or smoke during work.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Ventilation. NEVER direct water jet on liquid. Do NOT let this chemical enter the environment. (Extra personal protection: chemical protection suit including self-contained breathing apparatus).
Fireproof if in building. Cool.

UN Hazard Class: 2.2
ICSC: 1299 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

PHYSICAL STATE; APPEARANCE:
COMPRESSED LIQUEFIED GAS.

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

CHEMICAL DANGERS:
On contact with hot surfaces or flames this substance decomposes forming toxic and corrosive gases including hydrogen chloride and hydrogen fluoride.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation.

INHALATION RISK:
A harmful concentration of this gas in the air will be reached very quickly on loss of containment.

EFFECTS OF SHORT-TERM EXPOSURE:
Rapid evaporation of the liquid may cause frostbite. Exposure at high level may result in unconsciousness.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Animal tests show that this substance possibly causes toxic effects upon human reproduction.

PHYSICAL
PROPERTIES

Boiling point: 6.9°C
Melting point: -105.5°C
Relative density (water = 1): 1.4
Solubility in water, g/100 ml at 25°C: 0.89
Vapour pressure, kPa at 20°C: 180
Relative vapour density (air = 1): 4.1

ENVIRONMENTAL
DATA

This substance may be hazardous to the environment; special attention should be given to its impact on the ozone layer. Avoid release to the environment in circumstances different to normal use.

N O T E S

High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Check oxygen content before entering area. Do NOT use in the vicinity of a fire or a hot surface, or during welding. Turn leaking cylinder with the leak up to prevent escape of gas in liquid state. Freon 133a, Genetron 133a are trade names.
Transport Emergency Card: TEC (R)-20G39.
