  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Flammable. Gives off irritating or toxic fumes (or gases) in a fire.  Above 35°C explosive vapour/air mixtures may be formed.  NO open flames, NO sparks and NO smoking.  Above 35°C use a closed system, ventilation and explosion-proof electrical equipment.  Use water spray, powder, carbon dioxide, alcohol-resistant foam.  In case of fire: keep drums, etc., cool by spraying with water. 

 AVOID ALL CONTACT!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Sore throat. Cough. Burning sensation. Shortness of breath. Laboured breathing. Symptoms may be delayed.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Refer for medical attention. 
Skin Pain. Redness. Serious skin burns.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Pain. Blurred vision. 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 Burning sensation. Abdominal pain. Shock or collapse.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Wash away remainder with plenty of water. Personal protection: chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical enter the environment.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS LIQUID. 

Physical dangers
 

Chemical dangers
Decomposes on heating and on burning. This produces toxic fumes including nitrogen oxides. The solution in water is a medium strong base. Reacts with strong oxidants, acids, acid chlorides and acid anhydrides. Reacts with 1;2-dichloroethane. This generates explosion hazard. The substance ignites on contact with cellulose nitrate of high surface area.

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 eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation of the vapour may cause lung oedema. See Notes. Medical observation is indicated. 

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C. 

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


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
The substance is harmful to aquatic organisms. 

NOTES
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort.
Rest and medical observation is therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
