TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible.  NO open flames.  Use water spray, powder, alcohol-resistant foam, carbon dioxide. 
EXPLOSION Above 93°C explosive vapour/air mixtures may be formed.  Above 93°C use a closed system and ventilation.   
 
EXPOSURE   PREVENT GENERATION OF MISTS! AVOID EXPOSURE OF (PREGNANT) WOMEN!   
Inhalation   Use ventilation.  Fresh air, rest. 
Skin Dry skin.  Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes   Wear safety spectacles.  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.  Rinse mouth. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Collect leaking liquid in sealable containers. Wash away remainder with plenty of water.

IMPORTANT DATA
Physical State; Appearance
COLOURLESS LIQUID. 

Physical dangers
 

Chemical dangers
The substance can presumably form explosive peroxides. Reacts with strong oxidants. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
EU OEL ( selected): 10ppm, 50.1mg/m³ as TWA;. 

Routes of exposure
The substance can be absorbed into the body by inhalation, 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
 

Effects of long-term or repeated exposure
The liquid defats the skin. Animal tests show that this substance possibly causes toxicity to human reproduction or development.
