TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  Use water spray, powder, foam, carbon dioxide. 
EXPLOSION Above 63°C explosive vapour/air mixtures may be formed.  Above 63°C use a closed system, ventilation and explosion-proof electrical equipment.   
 
EXPOSURE   AVOID ALL CONTACT!   
Inhalation Cough. Sore throat. Lethargy. Nausea.  Use closed system.  Fresh air, rest. Refer for medical attention. 
Skin Redness. Pain.  Protective gloves. Protective clothing.  Rinse skin with plenty of water or shower. 
Eyes Redness. Pain.  Wear face shield or eye protection in combination with breathing protection.  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. Wash hands before eating.  Give one or two glasses of water to drink. Refer for medical attention .

Physical dangers
 

Chemical dangers
Reacts with reducing agents and strong oxidants. Decomposes on heating and on burning. This produces toxic and corrosive fumes. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK: Carcinogen category: 2; Skin absorption (H); (DFG 2003). 

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

Inhalation risk
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. 

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

Effects of long-term or repeated exposure
The substance may have effects on the respiratory tract. This may result in tissue lesions.
