TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  Use powder, carbon dioxide. NO hydrous agents. NO water. 
EXPLOSION     In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water. 
 
EXPOSURE   AVOID ALL CONTACT!   
Inhalation Sore throat. Cough. Burning sensation. 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 Pain. Redness. Blisters. Skin burns.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Pain. Redness. Severe deep burns. Loss of vision.  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. 
Ingestion Burning sensation. Abdominal pain. Shock or collapse.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Refer for medical attention .

IMPORTANT DATA
Physical State; Appearance
LIGHT-AMBER-TO-YELLOWISH-RED OILY FUMING LIQUID WITH PUNGENT ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes on heating and on burning. This produces toxic and corrosive fumes including hydrogen chloride, hydrogen sulfide and sulfur oxides. Reacts with peroxides, phosphorus oxides and some organic compounds. This generates fire and explosion hazard. Reacts violently with water. This produces sulfur, hydrogen chloride, sulfur dioxide, hydrogen sulfide, sulfite and thiosulfate. Attacks many metals in the presence of water. 

Occupational exposure limits
TLV: 1ppm, 5.5mg/m³ (ceiling value); (ACGIH 1996). 

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

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
Lachrymation. The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation of the vapour may cause lung oedema. See Notes. The effects may be delayed. Medical observation is indicated. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 138°C
Melting point: -77°C
Relative density (water = 1): 1.7
Solubility in water: reaction
Vapour pressure, kPa at 20°C: 0.90
Relative vapour density (air = 1): 4.7
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.03
Flash point: 118.5°C c.c.
Auto-ignition temperature: 234°C  
 

NOTES
Reacts violently with fire extinguishing agents such as water.
The occupational exposure limit value should not be exceeded during any part of the working exposure.
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 spray, by a doctor or a person authorized by him/her, should be considered.
Card has been partially updated in November 2008: see Occupational Exposure Limits, EU Classification, Packaging & labelling.
