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, alcohol-resistant foam, carbon dioxide. 
EXPLOSION Above 85°C explosive vapour/air mixtures may be formed.  Above 85°C use a closed system and ventilation.   
 
EXPOSURE   STRICT HYGIENE! PREVENT GENERATION OF MISTS!   
Inhalation Cough. Headache. Shortness of breath. Sore throat.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness. Pain. Skin burns.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Pain. Severe deep burns.  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 Abdominal pain. Burning sensation. Shock or collapse.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. 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. Collect leaking and spilled liquid in sealable containers as far as possible. Cautiously neutralize spilled liquid. Then wash away with plenty of water.  Do not transport with food and feedstuffs.

IMPORTANT DATA

COLOURLESS VISCOUS HYGROSCOPIC LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes on heating and on burning. This produces toxic and corrosive gases including nitrogen oxides. The substance is a medium strong base. Reacts with cellulose nitrate. This generates fire and explosion hazard. Reacts violently with strong acids and strong oxidants. Attacks copper, aluminium, their alloys and rubber. 

Occupational exposure limits
TLV: 3 ppm as TWA; 6 ppm as STEL; (ACGIH 2004).
MAK: 2 ppm, 5.1 mg/m³; Peak limitation category: I(2); Pregnancy risk group: C; Sensitization of skin (SH); (DFG 2004).
EU OEL: 1 ppm, 2.5 mg/m³ as TWA; 3 ppm, 7.6 mg/m³ as STEL (skin); (EU 2006). 

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

Inhalation risk
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster. 

Effects of short-term exposure
The substance is corrosive to the respiratory tract, skin and eyes. Corrosive on ingestion. The vapour is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the central nervous system. Exposure could cause lowering of consciousness. 

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