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

PREVENT DISPERSION OF DUST!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Sore throat. Dizziness. Headache. Nausea. Convulsions.	Use local exhaust or breathing protection.	Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. See Notes.
Skin	Redness. Pain.	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	Abdominal pain. Diarrhoea. Headache. Nausea. Vomiting. Convulsions.	Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Give a slurry of activated charcoal in water to drink. Do NOT induce vomiting. Refer for medical attention . See Notes.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Ventilation. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Personal protection: particulate filter respirator adapted to the airborne concentration of the substance.	According to UN GHS Criteria Transportation UN Classification UN Hazard Class: 6.1; UN Pack Group: III
STORAGE
Separated from strong oxidants, strong bases, strong acids, strong reducing agents and food and feedstuffs. Well closed.
PACKAGING
Do not transport with food and feedstuffs.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS WAXY CRYSTALS. Physical dangers Chemical dangers Decomposes on burning. Decomposes on contact with acids. This produces toxic and corrosive fumes including nitrogen oxides and cyanides. Reacts with strong bases. This produces ammonia. Reacts with strong oxidants and strong reducing agents.	Formula: C₄H₄N₂ / CNCH₂CH₂CN Molecular mass: 80.1 Boiling point: 265°C Melting point: 54°C Density: 1.02 g/cm³ Solubility in water, g/100ml at 20°C: 13 Relative vapour density (air = 1): 2.1 Flash point: 132°C Octanol/water partition coefficient as log Pow: -0.99

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by ingestion and by inhalation. Effects of short-term exposure The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the cellular respiration (inhibition). This may result in convulsions and respiratory failure. The effects may be delayed. Exposure at high levels could cause death.	Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. Effects of long-term or repeated exposure
