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 96°C explosive vapour/air mixtures may be formed.  Above 96°C use a closed system and ventilation.   
 
EXPOSURE      
Inhalation   Use ventilation.  Fresh air, rest. 
Skin Dry skin.  Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness.  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.   
EC Classification

IMPORTANT DATA
Physical State; Appearance
COLOURLESS HYGROSCOPIC LIQUID. 

Physical dangers
No data. 

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

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK (inhalable fraction): 50 mg/m³; Peak limitation category: I(2); Pregnancy risk group: C; (DFG 2006). 

Routes of exposure
 

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 mildly irritating to the eyes. 

Effects of long-term or repeated exposure
The liquid defats the skin.
