  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire. See Chemical dangers  Risk of fire and explosion on contact with oxidants. See Chemical Dangers.  NO open flames. NO contact with oxidizing agents.    Use powder, alcohol-resistant foam, water spray, carbon dioxide.  In case of fire: keep cylinder cool by spraying with water. 

 PREVENT GENERATION OF MISTS! AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Sore throat. Cough. Burning sensation. Laboured breathing. Shortness of breath.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Refer immediately for medical attention. 
Skin Redness. Pain. Skin burns. Blisters.  Protective gloves. Protective clothing.  First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer immediately for medical attention. 
Eyes Redness. Pain. Loss of vision. Severe deep burns.  Wear face shield or eye protection in combination with breathing protection.  Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention. 
Ingestion Burns in mouth and throat. Burning sensation in the throat and chest. Abdominal pain. Shock or collapse.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS-TO-YELLOW HYGROSCOPIC VISCOUS LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic fumes including nitrogen oxides. The substance is a strong base. It reacts violently with acid and is corrosive to aluminium, copper and zinc. Reacts violently with strong oxidants. This generates fire and explosion hazard. This produces toxic fumes. Attacks some coatings, some forms of plastic 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. 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, but only after initial corrosive effects on eyes and/or airways have become manifest. 

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. Repeated or prolonged inhalation may cause asthma. See Notes. 


Occupational exposure limits
MAK sensitization of skin (SH) 

ENVIRONMENT
The substance is toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. It is strongly advised not to let the chemical enter into the environment. 

NOTES
The symptoms of asthma 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.
Immediate administration of an appropriate inhalation therapy by a doctor, or by an authorized person, should be considered.
Anyone who has shown symptoms of asthma due to this substance should avoid all further contact.
