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. 
 
EXPOSURE      
Inhalation Dizziness. Headache. Unconciousness.  Use 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 Redness. See Skin.  Wear 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 refer for medical attention. 
Ingestion      

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Ventilation. NEVER direct water jet on liquid. Personal protection: chemical protection suit including self-contained breathing apparatus.

EMERGENCY RESPONSE SAFE STORAGE
Transport Emergency Card: TEC (R)-644.  Fireproof if in building. Cool. 

IMPORTANT DATA
Physical State; Appearance
COLOURLESS COMPRESSED LIQUEFIED GAS. 

Physical dangers
The vapour is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen. 

Chemical dangers
Decomposes on contact with hot surfaces or flames. This produces toxic fumes including hydrogen bromide and hydrogen fluoride. Attacks plastics, rubber and coatings. 

Occupational exposure limits
TLV: 1000ppm, 6090mg/m³ as TWA; (ACGIH 1997).
MAK: 1000 ppm, 6200 mg/m³; Peak limitation category: II(8); Pregnancy risk group: C; (DFG 2007). 

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
The substance is irritating to the eyes. Rapid evaporation of the liquid may cause frostbite. The substance may cause effects on the central nervous system. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: -58°C
Melting point: -168°C
Relative density (water = 1): 1.5
Solubility in water: none
Vapour pressure, kPa at 20°C: 1434
Relative vapour density (air = 1): 5.1

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.
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
Flugex 13B1, Freon 13B1, Halon 1301, Khladon 13B1, and Refrigerant 13B1 are trade names.
Card has been partially updated in March 2008: see Occupational Exposure Limits.
