TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Flammable. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames, NO sparks and NO smoking.  Use water spray, foam, alcohol-resistant foam, dry powder, carbon dioxide. 
EXPLOSION Above 52°C explosive vapour/air mixtures may be formed.  Above 52°C use a closed system, ventilation and explosion-proof electrical equipment.  In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   STRICT HYGIENE!   
Inhalation Cough. Laboured breathing. Sore throat.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. 
Skin Redness. Pain. Skin burns.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes 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. Give one or two glasses of water to drink. Do NOT induce vomiting. Refer for medical attention .

Physical dangers
 

Chemical dangers
Decomposes on burning. This produces toxic fumes of nitrogen oxides. The solution in water is a medium strong base. Reacts with oxidants. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly on spraying. 

Effects of short-term exposure
The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 142-150°C
Relative density (water = 1): 0.85
Solubility in water: very good
Vapour pressure, kPa at 20°C: 0.6
Relative vapour density (air = 1): 3
Relative density of the vapour/air-mixture at 20°C (air = 1): 1
Flash point: 52°C o.c. 
 

NOTES
Explosive limits are unknown in literature, although the substance is combustible and has a flash point < 61°C.
Health effects of exposure to the substance have not been investigated adequately.
Insufficient data are available on the effect of this substance on environment, therefore utmost care must be taken.
