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.  NO contact with bases, oxidizing agents or reducing agents.  In case of fire in the surroundings, use appropriate extinguishing media. 
EXPLOSION     In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   AVOID ALL CONTACT!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Cough. Sore throat. Burning sensation. Laboured breathing.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Refer immediately for medical attention. 
Skin Redness. Pain. Serious skin burns.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer immediately for medical attention. 
Eyes Redness. Pain. Severe deep burns.  Wear face shield or eye protection in combination with breathing protection.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Blue haze and halo. 
Ingestion Burning sensation in the throat and chest. Abdominal pain. Shock or collapse.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention.

IMPORTANT DATA
Physical State; Appearance
FUMING COLOURLESS LIQUID WITH PUNGENT ODOUR. 

Physical dangers
The vapour is heavier than air. 

Chemical dangers
Decomposes on contact with hot surfaces or flames. This produces toxic fumes. The substance is a medium strong acid. Reacts violently with strong bases, reducing agents and oxidants. This produces toxic and corrosive fumes including hydrogen fluoride. Attacks many metals. This produces flammable/explosive gas (hydrogen - see ICSC 0001). Attacks some forms of rubber. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
Serious by all routes of exposure. 

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 fume may cause lung oedema. See Notes. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 72°C
Melting point: -15°C
Relative density (water = 1): 1.5
Solubility in water, g/100ml at 20°C: 100 (very good)
Vapour pressure, kPa at 20°C: 11
Relative vapour density (air = 1): 3.9
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.3
Octanol/water partition coefficient as log Pow: -2.1  
The substance is harmful to aquatic organisms. 

NOTES
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.
