  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Flammable. Gives off irritating or toxic fumes (or gases) in a fire.  Above 33°C explosive vapour/air mixtures may be formed.  NO open flames, NO sparks and NO smoking. NO contact with oxidizing agents.  Above 33°C use a closed system, ventilation and explosion-proof electrical equipment.  Use water in large amounts, powder, alcohol-resistant foam, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

 AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS PREVENTION FIRST AID
Inhalation Sore throat. Cough. Burning sensation. Shortness of breath. Laboured breathing. See Notes.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer immediately for medical attention. 
Skin Pain. Redness. Skin burns.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer immediately for medical attention. 
Eyes Pain. Redness. Burns. Loss of vision.  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. Sore throat. Abdominal pain. Nausea. Vomiting. 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 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. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
HYGROSCOPIC COLOURLESS LIQUID WITH PUNGENT ODOUR. 

Physical dangers
No data. 

Chemical dangers
Decomposes on burning. This produces toxic fumes including nitrogen oxides. The substance is a strong base. It reacts violently with acid and is corrosive. Reacts with acid anhydrides, acid chlorides and strong oxidants.

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. Inhalation may cause lung oedema. See Notes. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. Medical observation is indicated. 

Inhalation risk
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C. 

Effects of long-term or repeated exposure
 


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
The substance is harmful to aquatic organisms. 

NOTES
Immediate administration of an appropriate inhalation therapy by a doctor, or by an authorized person, should be considered.
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.
Other melting points: -37 °C (technical product).
