  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Flammable. Gives off irritating or toxic fumes (or gases) in a fire.  Above 47°C explosive vapour/air mixtures may be formed. Risk of fire and explosion on contact with strong acids or strong oxidizing agents.  NO open flames, NO sparks and NO smoking. NO contact with strong oxidizing agents.  Above 47°C use a closed system, ventilation and explosion-proof electrical equipment.  Use alcohol-resistant foam, water, powder, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

 PREVENT GENERATION OF MISTS! AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS PREVENTION FIRST AID
Inhalation Cough. Sore throat. Burning sensation. Shortness of breath. Laboured breathing.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer immediately for medical attention. 
Skin Redness. Pain. Serious skin burns.  Protective gloves. Protective clothing.  Wear protective gloves when administering first aid. Remove contaminated clothes. See Notes. Rinse skin with plenty of water or shower for at least 15 minutes. Refer immediately for medical attention . 
Eyes Redness. Pain. Blurred vision. 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 Burns in mouth and throat. Burning sensation behind the breastbone. Abdominal pain. Vomiting. Shock or collapse.  Do not eat, drink, or smoke during work.  Rinse mouth. Give nothing to drink. Do NOT induce vomiting. Refer immediately for medical attention. 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Remove all ignition sources. Personal protection: complete protective clothing including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Cover the spilled material with inert absorbent or sand. Then store and dispose of according to local regulations. Wash away remainder with plenty of water.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes on burning. This produces toxic fumes including nitrogen oxides. The substance is a strong base. Reacts violently with strong oxidants. This generates fire and explosion hazard. Attacks some metals and some plastics. Solutions in water slowly etch glass.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
Serious local effects by all routes of exposure. 

Effects of short-term exposure
The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Contact of the vapour with the eyes may cause visual disturbances. Exposure could cause asphyxiation due to swelling in the throat. Inhalation of high concentrations may cause lung oedema, but only after initial corrosive effects on the eyes and the upper respiratory tract have become manifest. See Notes. 

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 with skin may cause dermatitis. 


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
The substance is toxic 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 are therefore essential.
Isolate contaminated clothing by sealing in a bag or other container.
