TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Gives off irritating or toxic fumes (or gases) in a fire. Not combustible.    NO water. In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION     In case of fire: keep cylinder cool by spraying with water. NO direct contact with water. 
 
EXPOSURE   AVOID ALL CONTACT!   
Inhalation Burning sensation. Cough. Sore throat. Headache. Nausea. Vomiting. Shortness of breath. Laboured breathing. Symptoms may be delayed. See Notes.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. 
Skin Pain. Redness. Skin burns. ON CONTACT WITH LIQUID: FROSTBITE.  Cold-insulating gloves. Protective clothing.  ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Pain. Blurred vision. Severe deep burns. ON CONTACT WITH LIQUID: FROSTBITE.  Wear safety goggles, face shield 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   Do not eat, drink, or smoke during work.

IMPORTANT DATA
Physical State; Appearance
COLOURLESS GAS WITH CHARACTERISTIC ODOUR. 

Physical dangers
The gas is heavier than air. 

Chemical dangers
Reacts violently with water and acids. This produces toxic and corrosive fumes. Attacks glass and metal. 

Occupational exposure limits
TLV: 0.1ppm (ceiling value); (ACGIH 2003). 

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 corrosive to the eyes, skin and respiratory tract. The liquid may cause frostbite. Inhalation of of this gas may cause lung oedema. See Notes. 

Effects of long-term or repeated exposure
The substance may have effects on the bones and teeth. This may result in fluorosis. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: -40°C
Melting point: -124°C
Solubility in water: reaction
Relative vapour density (air = 1): 3.78  
 

NOTES
The occupational exposure limit value should not be exceeded during any part of the working exposure.
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort.
Rest and medical observation is therefore essential.
