TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible.  NO open flames.  Use foam, alcohol-resistant foam, dry powder, water spray. 
EXPLOSION      
 
EXPOSURE      
Inhalation Cough. Nausea. Sore throat.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin Redness. Pain.  Protective gloves.  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 Nausea. Diarrhoea. Vomiting.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. 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. Do NOT let this chemical enter the environment. Collect leaking and spilled liquid in covered containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.   
EC Classification
Symbol: Xi; R: 36; S: (2)-24 
UN Classification
 
GHS Classification
 

EMERGENCY RESPONSE SAFE STORAGE
NFPA Code: H1; F1; R0.  Store in an area without drain or sewer access. Separated from strong acids. 

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

Physical dangers
The vapour is heavier than air. 

Chemical dangers
Decomposes on heating. This produces toxic fumes. The solution in water is a medium strong base. Reacts violently with acids and oxidants. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
The substance can be absorbed into the body by ingestion. 

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

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

Effects of long-term or repeated exposure
