	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Combustible. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames.	Use powder, alcohol-resistant foam, carbon dioxide.


	SYMPTOMS	PREVENTION	FIRST AID
Inhalation		Use ventilation.	Fresh air, rest.
Skin	Redness.	Protective gloves.	Rinse skin with plenty of water or shower.
Eyes	Redness. Pain.	Wear safety goggles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion		Do not eat, drink, or smoke during work.	Rinse mouth.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. 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.	According to UN GHS Criteria Transportation UN Classification
STORAGE
Separated from acids, bases and oxidants. Cool. Dry. Keep in a well-ventilated room.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS-TO-YELLOW LIQUID. Physical dangers Chemical dangers The substance may polymerize under the influence of organic bases. Decomposes on heating and on contact with acids, acid fumes and water. This produces highly toxic fumes including hydrogen cyanide. Reacts violently with strong oxidants.	Formula: C₃H₅NO / HOCH₂CH₂CN Molecular mass: 71.08 Decomposes at 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
