TYPES OF HAZARD
/ EXPOSURE
ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE-FIGHTING
FIRE Flammable. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames, NO sparks and NO smoking.  Use water spray, powder, foam, carbon dioxide. 
EXPLOSION Above 25°C explosive vapour/air mixtures may be formed.  Above 25°C use a closed system, ventilation and explosion-proof electrical equipment.  In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   AVOID ALL CONTACT! PREVENT GENERATION OF MISTS!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Cough. Sore throat. Headache. Dizziness. Nausea. Vomiting.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness.  Protective gloves. Protective clothing.  Wear protective gloves when administering first aid. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Redness.  Wear safety goggles 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 Abdominal pain.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. Do NOT induce vomiting. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Ventilation. Remove all ignition sources. Personal protection: chemical protection suit including self-contained breathing apparatus. Collect leaking and spilled liquid in sealable plastic containers as far as possible. Do NOT let this chemical enter the environment.

EMERGENCY RESPONSE SAFE STORAGE
NFPA Code: H2; F3; R0.  Fireproof. Separated from metals and oxidants. Well closed. Provision to contain effluent from fire extinguishing. Store in an area without drain or sewer access. 

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

Physical dangers
The vapour is heavier than air and may travel along the ground; distant ignition possible. As a result of flow, agitation, etc., electrostatic charges can be generated. 

Chemical dangers
Decomposes on burning. This produces toxic and corrosive fumes including hydrogen chloride. Reacts with oxidants and metals. 

Occupational exposure limits
TLV: 1ppm as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2012).
MAK: Carcinogen category: 2; Skin absorption (H); Sensitization of skin (SH); (DFG 2012). 

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 very quickly on evaporation of this substance at 20°C. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the central nervous system. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. This substance is possibly carcinogenic to humans.
