TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames, NO sparks, and NO smoking. NO contact with hot surfaces.
Powder, AFFF, foam, carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
STRICT HYGIENE!
IN ALL CASES CONSULT A DOCTOR!
Inhalation Confusion. Dizziness. Dullness. Headache. Nausea. Vomiting.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention. See Notes.
Skin MAY BE ABSORBED! Dry skin. Pain.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes Severe deep burns.
Safety spectacles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion Unconsciousness. (Further see Inhalation).
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.

IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
The vapour mixes well with air, explosive mixtures are easily formed.

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic fumes including nitrogen oxides and hydrogen cyanide. Reacts violently with strong oxidants causing fire and explosion hazard. Reacts with acids, steam, warm water giving off toxic and flammable hydrogen cyanide.

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 contamination of the air can be reached very quickly on evaporation of this substance at 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the iron metabolism, resulting in asphyxia. Exposure may result in unconsciousness, cardiac dysrhythmia and death. The effects may be delayed. Medical observation is indicated.

PHYSICAL PROPERTIES
Boiling point: 97C
Melting point: -92C
Relative density (water = 1): 0.78
Solubility in water, g/100 ml at 20C: 10
Vapour pressure, kPa at 20C: 5.2
Relative vapour density (air = 1): 1.9
Relative density of the vapour/air-mixture at 20C (air = 1): 1.05
Flash point: 6C c.c.
Explosive limits, vol% in air: 3.1-?
Octanol/water partition coefficient as log Pow: 0.16
ENVIRONMENTAL DATA
This substance may be hazardous to the environment; special attention should be given to aquatic organisms.
NOTES
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Do NOT take working clothes home. Card has been partly updated in October 2005. See section Emergency Response.
