  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  Above 85°C explosive vapour/air mixtures may be formed.  NO open flames.  Above 85°C use a closed system and ventilation.  Use water spray, powder, alcohol-resistant foam, carbon dioxide.   

 STRICT HYGIENE! PREVENT GENERATION OF MISTS!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Sore throat. Headache. Shortness of breath. Drowsiness.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer immediately for medical attention. 
Skin MAY BE ABSORBED! Redness. Pain. Skin burns.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer immediately for medical attention . 
Eyes Redness. Pain. Severe burns.  Wear face shield or eye protection in combination with breathing protection.  Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention. 
Ingestion Burning sensation. Abdominal pain. Shortness of breath. Shock or collapse.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: filter respirator for ammonia and organic ammonia derivatives adapted to the airborne concentration of the substance. Collect leaking liquid in sealable plastic containers. Absorb remaining liquid in inert absorbent. Then wash away with plenty of water. Do NOT let this chemical enter the environment.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
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. Reacts violently with strong acids and strong oxidants. This generates fire and explosion hazard. The substance is a medium strong base. Attacks copper, aluminium, their alloys and rubber.

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The substance is corrosive to the 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. This may result in lowering of consciousness. 

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 long-term or repeated exposure
 


OCCUPATIONAL EXPOSURE LIMITS
TLV: 3 ppm as TWA; 6 ppm as STEL.
MAK: 0.51 mg/m3, 0.2 ppm; peak limitation category: I(1); sensitization of skin (SH); pregnancy risk group: C.
EU-OEL: 2.5 mg/m3, 1 ppm as TWA; 7.6 mg/m3, 3 ppm as STEL; (skin) 

ENVIRONMENT
The substance is harmful to aquatic organisms. The substance may cause long-term effects in the aquatic environment. Avoid release to the environment in circumstances different to normal use. 

NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
The odour warning when the exposure limit value is exceeded is insufficient.
Do NOT take working clothes home.
