TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Not combustible. 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 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, face shield. 
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 PACKAGING & LABELLING

SULPHUR HEXAFLUORIDE ICSC: 0571
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE: 
ODOURLESS, 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: 
The substance decomposes on heating above 500℃ producing toxic and corrosive fumes including sulfur oxides, fluorine compounds.

OCCUPATIONAL EXPOSURE LIMITS: 
TLV: 1000 ppm as TWA; (ACGIH 2004).
MAK: 1000 ppm, 6100 mg/m3; Peak limitation category: II(8); Pregnancy risk group: D; (DFG 2006).
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.

PHYSICAL PROPERTIES
Sublimation point: -64℃
Melting point: -51℃
Relative density (water = 1): 1.9
Solubility in water: none
Relative vapour density (air = 1): 5
Octanol/water partition coefficient as log Pow: 1.68
ENVIRONMENTAL DATA

NOTES
The technical product may contain impurities which alter the health effects. High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death. Check oxygen content before entering area. There is no odour warning even when toxic concentrations are present. Turn leaking cylinder with the leak up to prevent escape of gas in liquid state. Elegas and Esaflon are trade names.
Card has been partly updated in October 2005. See sections Occupational Exposure Limits, Emergency Response. Card has been partially updated in August 2007: see Occupational Exposure Limits.
