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 78°C explosive vapour/air mixtures may be formed.  Above 78°C use a closed system and ventilation.   
 
EXPOSURE      
Inhalation   Use ventilation. Use local exhaust.  Fresh air, rest. 
Skin Dry skin.  Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  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
No data. 

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

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK: 100 mg/m³; Peak limitation category: I(1); Pregnancy risk group: C; (DFG 2003). 

Routes of exposure
 

Inhalation risk
A harmful contamination of the air will be reached slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster. 

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

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