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 dry powder, foam, carbon dioxide. 
EXPLOSION      
 
EXPOSURE   PREVENT GENERATION OF MISTS!   
Inhalation Cough. Sore throat. Shortness of breath.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer immediately for medical attention. 
Skin Redness. Pain.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Redness. Pain. Burns.  Wear safety goggles, face shield or eye protection in combination with breathing protection.  Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention. 
Ingestion Cough. Sore throat.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Seek medical attention if you feel unwell. 

SPILLAGE DISPOSAL

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

Physical dangers
No data. 

Chemical dangers
Decomposes on heating and on contact with acids and water. This produces toxic and corrosive fumes including hydrogen chloride. Reacts violently with strong oxidants, amines and light metals. This generates fire and explosion hazard. Contact with air generates hydrogen chloride (see ICSC 0163). Attacks plastic. 

Occupational exposure limits
TLV: 0.1ppm as STEL; (skin); A2 (suspected human carcinogen); (ACGIH 2008).
MAK: Carcinogen category: 2; Skin absorption (H); (DFG 2008). 

Routes of exposure
The substance can be absorbed into the body by inhalation, through the skin and by ingestion. 

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

Effects of short-term exposure
The substance is irritating to the skin and respiratory tract. The substance is severely irritating to the eyes. If swallowed the substance may cause vomiting and could result in aspiration pneumonitis. 

Effects of long-term or repeated exposure
The substance may have effects on the lungs, liver, kidneys and thyroid. This substance is probably carcinogenic to humans.

NOTES
Combustible vapour/air mixtures difficult to ignite, may be developed under certain conditions.
The occupational exposure limit value should not be exceeded during any part of the working exposure.
Depending on the degree of exposure, periodic medical examination is suggested.
Refer for medical attention if breathing difficulties and/or fever develop.
