  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible but enhances combustion of other substances. Many reactions may cause fire or explosion.  Risk of fire and explosion on contact with many substances. See Chemical Dangers.  NO contact with water, combustible substances or reducing agents.    NO water. In case of fire in the surroundings, use appropriate extinguishing media. See Notes.  In case of fire: keep cylinder cool by spraying with water. NO direct contact with water. Combat fire from a sheltered position. See Notes. 

 AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS PREVENTION FIRST AID
Inhalation Burning sensation. Cough. Sore throat. 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 Redness. Pain. Skin burns. ON CONTACT WITH LIQUID: FROSTBITE.  Cold-insulating gloves. Protective clothing.  First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention . 
Eyes Redness. Pain. Severe deep burns.  Wear 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.

FLUORINE ICSC: 0046
PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
YELLOW COMPRESSED GAS WITH PUNGENT ODOUR. 

Physical dangers
The gas is heavier than air. 

Chemical dangers
The substance is a strong oxidant. It reacts with combustible and reducing materials. Reacts violently with water. This produces toxic and corrosive vapours of ozone (see ICSC 0068) and hydrogen fluoride (see ICSC 0283). Reacts violently with ammonia, metals, oxidants and many other materials. This generates fire and explosion hazard. 

Formula: F2
Molecular mass: 38.0
Boiling point: -188°C
Melting point: -219°C
Solubility in water: reaction
Relative vapour density (air = 1): 1.3  


EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is very corrosive to the eyes, skin and respiratory tract. Inhalation of this gas may cause lung oedema. See Notes. The liquid may cause frostbite. The effects may be delayed. Medical observation is indicated. 

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: 1 ppm as TWA; 2 ppm as STEL.
EU-OEL: 1.58 mg/m3, 1 ppm as TWA; 3.16 mg/m3, 2 ppm as STEL 

ENVIRONMENT
 

NOTES
Reacts violently with fire extinguishing agents such as water.
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 are therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
Do NOT spray water on leaking cylinder (to prevent corrosion of cylinder).
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
