EC Number: 201-993-5

	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, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

PREVENT DISPERSION OF DUST!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Sore throat.	Avoid inhalation of dust and mist. Use ventilation (not if powder), local exhaust or breathing protection.	Fresh air, rest. Seek medical attention if you feel unwell.
Skin	Redness.	Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap. Seek medical attention if you feel unwell.
Eyes	Redness. Pain.	Wear safety goggles or face shield.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion	No acute symptoms expected.	Do not eat, drink, or smoke during work.	Rinse mouth. Give one or two glasses of water to drink. Seek medical attention if you feel unwell.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into sealable 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 be harmful if swallowed Causes skin irritation Causes serious eye irritation May cause respiratory irritation Very toxic to aquatic life Transportation UN Classification UN Hazard Class: 9; UN Pack Group: III
STORAGE
Separated from strong oxidants, strong bases and food and feedstuffs. Store only in original container. Provision to contain effluent from fire extinguishing. Store in an area without drain or sewer access.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance WHITE CRYSTALS. Physical dangers Dust explosion possible if in powder or granular form, mixed with air. Chemical dangers Reacts with strong bases and strong oxidants. Decomposes on heating. This produces carbon dioxide, carbon monoxide and irritating fumes.

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. Effects of short-term exposure The substance is severely irritating to the eyes. The substance is irritating to the skin and respiratory tract.	Inhalation risk Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered. Effects of long-term or repeated exposure Tumours have been detected in experimental animals but may not be relevant to humans.
