TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible but enhances combustion of other substances. Many reactions may cause fire or explosion. Gives off irritating or toxic fumes (or gases) in a fire.  NO contact with flammables. NO contact with water, combustible substances or organic materials.  In case of fire in the surroundings, use appropriate extinguishing media. NO hydrous agents. 
EXPLOSION Risk of fire and explosion on contact with water, steam, fuels or organic materials.    In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water. Combat fire from a sheltered position. 
 
EXPOSURE   AVOID ALL CONTACT!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Burning sensation. Cough. Shortness of breath. Sore throat. Laboured breathing. Symptoms may be delayed. See Notes.  Use closed system or ventilation.  Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. 
Skin Redness. Pain. Skin burns. Blisters.  Protective gloves. Protective clothing.  Wear protective gloves when administering first aid. Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Pain. Blurred vision. Severe deep burns.  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 Abdominal pain. Burning sensation. Shock or collapse.  Do not eat, drink, or smoke during work. Wash hands before eating.  Do NOT induce vomiting. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in vermiculite, earth, dry sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer. Do NOT absorb in saw-dust or other combustible absorbents. NEVER direct water jet on liquid.  Airtight.
Unbreakable packaging.
Put breakable packaging into closed unbreakable container.
Do not transport with food and feedstuffs.

EMERGENCY RESPONSE SAFE STORAGE
Transport Emergency Card: TEC (R)-51GOTC-I.
NFPA Code: H4; F0; R3; W; OX. 
Separated from food and feedstuffs and all other substances. See Chemical Dangers. Dry. Well closed. Keep in a well-ventilated room. 

IMPORTANT DATA
Physical State; Appearance
PALE YELLOW-TO-COLOURLESS FUMING LIQUID WITH PUNGENT ODOUR. 

Physical dangers
The vapour is heavier than air. 

Chemical dangers
Decomposes above 460°C . Decomposes on contact with acids or acid fumes. This produces very toxic fumes of hydrogen fluoride(see ICSC 0283) and hydrogen bromide(see ICSC 0282). Reacts with fuels and organic compounds. This generates fire and explosion hazard. Reacts with water and steam. This produces toxic and corrosive fumes of hydrogen fluoride and hydrogen bromide. Reacts with all known elements, except nitrogen, oxygen and rare gases. 

Occupational exposure limits
TLV: 0.1ppm as TWA; (ACGIH 2004). 

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

Inhalation risk
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. 

Effects of short-term exposure
The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation of the vapour may cause lung oedema. See Notes. Exposure could cause death. 

Effects of long-term or repeated exposure
May cause fluorosis due to formation of hydrogen fluoride. Further see ICSC 0283. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 41°C
Melting point: -61°C
Relative density (water = 1): 2.5
Solubility in water: reaction
Vapour pressure, kPa at 20°C: 44
Relative vapour density (air = 1): 6.1  
 

NOTES
Reacts violently with fire extinguishing agents such as water.
Depending on the degree of exposure, periodic medical examination is suggested.
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.
Do NOT take working clothes home.
Card has been partly updated in October 2005.
