TYPES OF HAZARD
/ EXPOSURE
ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE-FIGHTING
FIRE Combustible under specific conditions. Heating will cause rise in pressure with risk of bursting. See Notes.  NO open flames. NO contact with hot surfaces.  Use powder, water spray, foam, carbon dioxide. 
EXPLOSION     In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   PREVENT GENERATION OF MISTS!   
Inhalation Cough. Dizziness. Drowsiness. Headache. Nausea.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin MAY BE ABSORBED! Dry skin. Redness.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Redness.  Wear safety spectacles or face shield.  Rinse with plenty of water (remove contact lenses if easily possible). Refer for medical attention. 
Ingestion Aspiration hazard! See Inhalation.  Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention . Do NOT induce vomiting.

IMPORTANT DATA
Physical State; Appearance
COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
The vapour is heavier than air. 

Chemical dangers
Decomposes on contact with hot surfaces or flames. This produces toxic and corrosive gases including hydrogen chloride (see ICSC 0163) and phosgene (see ICSC 0007). Reacts with strong bases, strong oxidants and metals. This generates fire and explosion hazard. 

Occupational exposure limits
TLV: 10ppm as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2009).
MAK: 10 ppm, 55 mg/m³; Carcinogen category: 3B; Peak limitation category: II(2); Skin absorption (H); (DFG 2008). 

Routes of exposure
The substance can be absorbed into the body by inhalation of its vapour, 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 eyes and respiratory tract. The substance is mildly irritating to the skin. The substance may cause effects on the central nervous system. This may result in lowering of consciousness. The substance may cause effects on the kidneys and liver. This may result in impaired functions. If swallowed the substance may cause vomiting and could result in aspiration pneumonitis. 

Effects of long-term or repeated exposure
The substance defats the skin, which may cause dryness or cracking. Repeated or prolonged contact with skin may cause dryness and cracking.
