TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRE FIGHTING
FIRE	Combustible. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames.	Powder, alcohol-resistant foam, carbon dioxide.
EXPLOSION

EXPOSURE
Inhalation		Ventilation.	Fresh air, rest.
Skin	Redness.	Protective gloves.	Rinse skin with plenty of water or shower.
Eyes	Redness. Pain.	Safety goggles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion		Do not eat, drink, or smoke during work.	Rinse mouth.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. (Extra personal protection: filter type B.)

EMERGENCY RESPONSE	STORAGE
NFPA Code: H1; F1; R2	Separated from acids, bases, oxidants. Cool. Dry. Keep in a well-ventilated room.

IMPORTANT DATA
Physical State; Appearance COLOURLESS TO YELLOW LIQUID Chemical dangers The substance may polymerize under the influence of organic base(s). The substance decomposes on heating or on contact with acids acid fumes, or water producing highly toxic fumes including hydrogen cyanide. Reacts violently with strong oxidants. Occupational exposure limits TLV not established.	Routes of exposure The substance can be absorbed into the body by inhalation of its vapour and by ingestion. Inhalation risk No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C. Effects of short-term exposure The substance is irritating to the eyes and the skin.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point (decomposes): 228°C Melting point: -46°C Relative density (water = 1): 1.04 Solubility in water: miscible Vapour pressure, Pa at 25°C: 10.7 Relative vapour density (air = 1): 2.45 Flash point: 129°C o.c. Auto-ignition temperature: 494°C Explosive limits, vol% in air: 2.3 - 12.1 Octanol/water partition coefficient as log Pow: -0.94

NOTES

This substance is less hazardous than some other nitriles which easily form hydrogen cyanide in the body.
