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: use appropriate extinguishing media.
EXPLOSION

In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.
EXPOSURE


 •INHALATION Suffocation. See Notes.
Ventilation.
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. 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


SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Ventilation. NEVER direct water jet on liquid. Do NOT let this chemical enter the environment. Personal protection: chemical protection suit including self-contained breathing apparatus.
Fireproof if in building. Cool.

UN Hazard Class: 2.2

PHYSICAL STATE; APPEARANCE:
COLOURLESS 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: 1000 ppm as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2005).
MAK: 1000 ppm 7100 mg/m³;
Peak limitation category: II(8); Pregnancy risk group: D;
(DFG 2006).
OSHA PEL: TWA 1000 ppm (7000 mg/m3)
NIOSH REL: TWA 1000 ppm (7000 mg/m3)
NIOSH IDLH: 15,000 ppm See: 76142


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. The substance may cause effects on the cardiovascular system , resulting in cardiac disorders .

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
PHYSICAL
PROPERTIES
Boiling point: 4.1°C
Melting point: -94°C
Relative density (water = 1): 1.5
Solubility in water, g/100 ml at 25°C: none
Vapour pressure, kPa at 25°C: 268
Relative vapour density (air = 1): 5.89
Octanol/water partition coefficient as log Pow: 2.8
ENVIRONMENTAL
DATA
Environmental Hazard placard This substance may be hazardous in the environment; special attention should be given to its impact on the ozone layer.
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. Arcton 114, Freon 114, Frigen 114, Genetron 114, Ledon 114, Propellant 114, Refrigerant 114, Ucon 114 are trade names. Card has been partly updated in October 2005.
