  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible.    NO open flames. NO contact with hot surfaces.    Use water in large amounts, powder, alcohol-resistant foam, carbon dioxide.  In case of fire: keep drums, etc., cool by spraying with water. 

 STRICT HYGIENE!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation Burning sensation. Cough. Laboured breathing. Shortness of breath. Sore throat. Symptoms may be delayed. See Notes.  Use ventilation (not if powder), local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. 
Skin MAY BE ABSORBED! Redness. Skin burns. Pain. Blisters.  Protective gloves. Protective clothing.  Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Pain. Severe deep burns.  Wear safety spectacles, 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 Abdominal cramps. Abdominal pain. Burning sensation. Shock or collapse.  Do not eat, drink, or smoke during work.  Rest. Refer for medical attention . See Notes.

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
HYGROSCOPIC PELLETS OR FLAKES WITH CHARACTERISTIC ODOUR. 

Physical dangers
 

Chemical dangers
On combustion, forms toxic and corrosive gases. Upon heating, toxic fumes are formed. This produces toxic fumes. The solution in water is a strong base. It reacts violently with acid and is corrosive. Reacts with oxidants. Attacks many metals in the presence of water.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol, 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 may cause lung oedema. See Notes. The effects may be delayed. 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
Repeated or prolonged contact with skin may cause dermatitis. 


OCCUPATIONAL EXPOSURE LIMITS
TLV: 0.5 ppm as TWA 

ENVIRONMENT
The substance is toxic to aquatic organisms. 

NOTES
The substance may exist as solid or liquid depending on ambient temperature.
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.
The recommendations on this Card also apply to Hexamethylenediamine solution, 70-80 %, UN No. 1783.
