TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible but enhances combustion of other substances. Gives off irritating or toxic fumes (or gases) in a fire.    Use powder, carbon dioxide. NO water. NO hydrous agents. 
EXPLOSION     In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water. 
 
EXPOSURE   AVOID ALL CONTACT!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Burning sensation. Cough. Laboured breathing. Nausea. Shortness of breath. Sore throat.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Refer immediately for medical attention. See Notes. 
Skin Redness. Serious skin burns. Pain.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer immediately for medical attention. Apply calcium gluconate to the burn areas. 
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). Refer immediately for medical attention. 
Ingestion Burns in mouth and throat. Sore throat. Burning sensation. Abdominal pain. Diarrhoea. Vomiting. 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
OILY COLOURLESS HYGROSCOPIC LIQUID WITH PUNGENT ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes on heating and on burning. This produces toxic and corrosive fumes including antimony and fluorine. Reacts violently with water. This produces toxic and corrosive hydrogen fluoride (see ICSC 0283). Attacks many metals. This produces a combustible/explosive gas (hydrogen - see ICSC 0001). 

Occupational exposure limits
TLV (as Sb): 0.5mg/m³ as TWA; (ACGIH 2010).
MAK: Carcinogen category: 2; Germ cell mutagen group: 3B; (DFG 2010). 

Routes of exposure
Serious local effects and systemic effects 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
Corrosive. Inhalation may cause severe swelling of the throat. This may result in asphyxia. Inhalation may cause lung oedema, but only after initial corrosive effects on eyes and/or airways have become manifest. Exposure at high levels could cause severe lung damage. See Notes. Medical observation is indicated. 

Effects of long-term or repeated exposure
The substance may have effects on the cardiovascular system and respiratory tract. This may result in impaired functions. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 141°C
Melting point: 8.3°C
Relative density (water = 1): 3.00
Solubility in water: reaction
Vapour pressure, kPa at 25°C: 1.33  
The substance is toxic to aquatic organisms. 

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.
Also consult ICSC 0283 (Hydrogen fluoride).
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
