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, ventilation and explosion-proof electrical equipment.  In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE      
Inhalation Sore throat. Cough.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin Dry skin. Redness.  Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear safety goggles.  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. Give one or two glasses of water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Ventilation. Collect leaking liquid in covered containers. Wash away remainder with plenty of water.

Physical dangers
 

Chemical dangers
Reacts with strong oxidants and strong acids. 

Occupational exposure limits
TLV: 25ppm, 121mg/m³ (ceiling value); (ACGIH 2003).
MAK: 10 ppm, 49 mg/m³; Peak limitation category: I(2); Pregnancy risk group: D; (DFG 2006). 

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol. 

Inhalation risk
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis.
