  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible but enhances combustion of other substances. 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. 

 STRICT HYGIENE!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Sore throat. Laboured breathing. Shortness of breath.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Refer for medical attention. 
Skin ON CONTACT WITH LIQUID: FROSTBITE.  Cold-insulating gloves. Protective clothing.  ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention . 
Eyes   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   Do not eat, drink, or smoke during work.   

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Ventilation. NEVER direct water jet on liquid. 

According to UN GHS Criteria

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS GAS OR COMPRESSED LIQUEFIED GAS WITH CHARACTERISTIC ODOUR. 

Physical dangers
No data. 

Chemical dangers
The substance is a strong oxidant. It reacts violently with combustible and reducing materials. This generates fire and explosion hazard. Reacts violently with nitrogenous bases and finely divided organic materials. This generates fire and explosion hazard. Attacks some forms of plastic, rubber and coatings. 

Formula: ClFO3
Molecular mass: 102.45
Boiling point: -46.7°C
Melting point: -147.7°C
Relative density (water = 1): 1.4 (liquid)
Solubility in water, g/100ml at 20°C: 0.06  


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 respiratory tract. Inhalation of this gas may cause lung oedema. See Notes. Inhalation of high concentrations may cause formation of methaemoglobin. The liquid may cause frostbite. Medical observation is indicated. The effects may be delayed. 

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
The substance may have effects on the blood. This may result in the formation of methaemoglobin. May cause fluorosis. See Notes. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: 3 ppm as TWA; 6 ppm as STEL 

ENVIRONMENT
 

NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
Turn leaking cylinder with the leak up to prevent escape of gas in liquid state.
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.
