	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Finely dispersed particles form explosive mixtures in air.	NO open flames. Prevent deposition of dust.	Use water spray, powder, foam, carbon dioxide.

PREVENT DISPERSION OF DUST! STRICT HYGIENE!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation		Use local exhaust.	Fresh air, rest.
Skin		Protective gloves. Protective clothing.	Wear protective gloves when administering first aid. Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes		Wear face shield.	Rinse with plenty of water (remove contact lenses if easily possible).
Ingestion		Do not eat, drink, or smoke during work.	Rinse mouth.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.	According to UN GHS Criteria WARNING May cause an allergic skin reaction Transportation UN Classification
STORAGE
Separated from strong oxidants. Keep in a well-ventilated room.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS CRYSTALS OR GREY POWDER. Physical dangers Dust explosion possible if in powder or granular form, mixed with air. Chemical dangers Decomposes on heating. This produces toxic fumes including carbon monoxide and nitrogen oxides. Reacts with oxidants. This generates fire and explosion hazard.	Formula: C₆H₅NHC₆H₄NHC₆H₅ / C₁₈H₁₆N₂ Molecular mass: 260.3 Melting point: 150-151°C Relative density (water = 1): 1.2 Solubility in water: none Relative vapour density (air = 1): 9.0 Flash point: 232°C c.c.
