TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  Use water spray, powder, alcohol-resistant foam, carbon dioxide. 
EXPLOSION Above 97°C explosive vapour/air mixtures may be formed.  Above 97°C use a closed system, ventilation and explosion-proof electrical equipment.  In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   PREVENT GENERATION OF MISTS! STRICT HYGIENE!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Sore throat. Cough. Burning sensation. Laboured breathing. Symptoms may be delayed. See Notes.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. 
Skin Pain. Serious skin burns.  Protective gloves. Protective clothing.  First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention . 
Eyes Pain. Severe deep 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. Abdominal pain. Shock or collapse.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Rest. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Personal protection: complete protective clothing including self-contained breathing apparatus.  Unbreakable packaging.
Put breakable packaging into closed unbreakable container.
Do not transport with food and feedstuffs.

Separated from strong oxidants, acids, organic nitro compounds and food and feedstuffs. Keep in a well-ventilated room. 

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

Physical dangers
The vapour is heavier than air. 

Chemical dangers
Decomposes on burning. This produces toxic and corrosive gases including nitrogen oxides. The solution in water is a strong base. It reacts violently with acid and is corrosive. Reacts violently with oxidants, nitric acid and organic nitro compounds. Attacks many metals in the presence of water. 

Occupational exposure limits
TLV: 1ppm as TWA; (skin); (ACGIH 2004).
MAK: Sensitization of skin (SH); (DFG 2004). 

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 contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C. 

Effects of short-term exposure
The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation of the vapour may cause lung oedema. See Notes. The effects may be delayed. Medical observation is indicated. 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause asthma. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 207°C
Melting point: -39°C
Relative density (water = 1): 0.96
Solubility in water: miscible
Vapour pressure, Pa at 20°C: 37
Relative vapour density (air = 1): 3.56
Flash point: 97°C c.c., 102°C o.c.
Auto-ignition temperature: 358°C
Explosive limits, vol% in air: 1-10
Octanol/water partition coefficient as log Pow: -1.3  
 

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.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
The odour warning when the exposure limit value is exceeded is insufficient.
Card has been partly updated in October 2005.
