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 74°C explosive vapour/air mixtures may be formed.  Above 74°C use a closed system and ventilation.  In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   PREVENT GENERATION OF MISTS!   
Inhalation Cough. Dizziness. Drowsiness.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin MAY BE ABSORBED! Dry skin. See Inhalation.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
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 See Inhalation.  Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Collect leaking and spilled liquid in sealable plastic containers as far as possible. Wash away remainder with plenty of water.

EMERGENCY RESPONSE SAFE STORAGE
NFPA Code: H0; F2; R0.  Separated from strong oxidants. Ventilation along the floor. 

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

Physical dangers
 

Chemical dangers
The substance can presumably form explosive peroxides in contact with air. Reacts violently with strong oxidants. Attacks many metals. This produces flammable/explosive gas (hydrogen - see ICSC 0001). 

Occupational exposure limits
MAK: 50 ppm, 310 mg/m³; Peak limitation category: I(1); Pregnancy risk group: D; (DFG 2008). 

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

Inhalation risk
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C. 

Effects of short-term exposure
The vapour is irritating to the eyes and respiratory tract. The substance may cause effects on the central nervous system. This may result in narcosis. 

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