TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Extremely flammable.  NO open flames, NO sparks and NO smoking.  Use water spray, powder, foam, carbon dioxide. 
EXPLOSION      
 
EXPOSURE   STRICT HYGIENE!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Drowsiness. Unconciousness.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin   Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Pain. 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   Do not eat, drink, or smoke during work.  Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Remove all ignition sources. Ventilation. Collect leaking and spilled liquid in sealable metal containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Personal protection: chemical protection suit including self-contained breathing apparatus.  Unbreakable packaging.
Put breakable packaging into closed unbreakable container.

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

Physical dangers
The vapour is heavier than air and may travel along the ground; distant ignition possible. 

Chemical dangers
Decomposes on burning. This produces toxic and corrosive gases. Reacts violently with oxidants, strong bases, aluminium, zinc and magnesium. Attacks plastics and rubber. 

Occupational exposure limits
TLV: 5ppm as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans);.
MAK: Carcinogen category: 2; (DFG 2004). 

Routes of exposure
The substance can be absorbed into the body by inhalation 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. The substance may cause effects on the central nervous system. Exposure could cause unconsciousness. 

Effects of long-term or repeated exposure
