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 water spray, foam, powder, carbon dioxide. 
EXPLOSION Above 63°C explosive vapour/air mixtures may be formed.  Above 63°C use a closed system and ventilation.   
 
EXPOSURE      
Inhalation Cough. Sore throat.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin Redness.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear safety spectacles or face shield.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Sore throat.  Do not eat, drink, or smoke during work.  Rinse mouth. Rest.

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

Physical dangers
 

Chemical dangers
The substance can form explosive peroxides under special conditions. Reacts violently with aluminium, bases, iron, oxidants and phenol. This generates fire and explosion hazard. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK (2b (not established but data is available)): (DFG 2005). 

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

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C. 

Effects of short-term exposure
The substance is irritating to the eyes. 

Effects of long-term or repeated exposure
