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 in large amounts, alcohol-resistant foam, dry powder, carbon dioxide. 
EXPLOSION      
 
EXPOSURE   PREVENT GENERATION OF MISTS!   
Inhalation Cough. Sore throat.  Use local exhaust. Use ventilation.  Fresh air, rest. 
Skin Redness.  Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes Redness.  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.  Give one or two glasses of water to drink. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Collect leaking and spilled liquid in covered containers as far as possible. Then wash away with plenty of water.   
EC Classification

EMERGENCY RESPONSE SAFE STORAGE
NFPA Code: H2; F1; R1.  Separated from oxidants. Well closed. Dry. 

IMPORTANT DATA
Physical State; Appearance
COLOURLESS VISCOUS HYGROSCOPIC LIQUID OR CRYSTALS WITH CHARACTERISTIC ODOUR. 

Physical dangers
 

Chemical dangers
The substance is a weak base. Reacts with oxidants. Decomposes on burning. This produces toxic and corrosive fumes including nitrogen oxides. 

Occupational exposure limits
TLV: 5mg/m³ as TWA; (ACGIH 2003).
MAK: Sensitization of skin (SH); (DFG 2002). 

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

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. 

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 may cause skin sensitization.
