  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION 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.  In case of fire: keep cylinder cool by spraying with water. 

   
  SYMPTOMS PREVENTION FIRST AID
Inhalation Dizziness. Headache. Unconsciousness.  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 CLASSIFICATION & LABELLING
Ventilation. NEVER direct water jet on liquid. Personal protection: chemical protection suit including self-contained breathing apparatus. 

According to UN GHS Criteria

 

Transportation
UN Classification

BROMOTRIFLUOROMETHANE ICSC: 0837
PHYSICAL & CHEMICAL INFORMATION

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. 

Formula: CBrF3
Molecular mass: 148.9
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
Octanol/water partition coefficient as log Pow: 1.86  


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation. 

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. 

Inhalation risk
A harmful concentration of this gas in the air will be reached very quickly on loss of containment. 

Effects of long-term or repeated exposure
 


OCCUPATIONAL EXPOSURE LIMITS
TLV: 1000 ppm as TWA.
MAK: 6200 mg/m3, 1000 ppm; peak limitation category: II(8); pregnancy risk group: C 

ENVIRONMENT
Avoid release to the environment because of 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.
