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, powder, alcohol-resistant foam, carbon dioxide. 
EXPLOSION Above 51°C explosive vapour/air mixtures may be formed.  Above 51°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!   
Inhalation Burning sensation. Cough. Headache. Nausea. Shortness of breath. Sore throat. 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 Redness. Serious skin burns.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Blurred vision. Severe deep burns.  Wear face shield.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Shock or collapse. Further see Inhalation.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Rest. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: chemical protection suit including self-contained breathing apparatus. Remove all ignition sources. 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.  Do not transport with food and feedstuffs.

IMPORTANT DATA
Physical State; Appearance
COLOURLESS-TO-LIGHT-YELLOW LIQUID WITH PUNGENT ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes on burning. This produces toxic and corrosive gases including nitrogen oxides. Reacts violently with oxidants, acids, acid chlorides, acid anhydrides and mercury. Attacks plastics, copper, copper alloys, aluminium, zinc, zinc alloys and galvanized surfaces. Solutions in water may attack glass. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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

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 short-term exposure
The substance is corrosive to the skin and eyes. The substance is severely irritating to the respiratory tract. Inhalation of the vapour or mist may cause lung oedema. See Notes. The substance may cause effects on the central nervous system. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 202-203°C
Melting point: -44°C
Relative density (water = 1): 0.8
Solubility in water: none
Vapour pressure, Pa at 20°C: 40
Relative vapour density (air = 1): 5.4
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.00
Flash point: 51°C c.c. 
 

NOTES
Other melting points: -8°C; -32°C.
Explosive limits are unknown in literature, although the substance is combustible and has a flash point < 55°C.
Environmental effects from the substance have not been investigated adequately.
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.
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
