	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Flammable. 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.

PREVENT DISPERSION OF DUST!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Sore throat.	Use local exhaust or breathing protection.	Fresh air, rest.
Skin	Redness.	Protective gloves.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes	Redness. Stinging sensation. Pain. Burns.	Wear safety goggles or eye protection in combination with breathing protection.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion	Sore throat. Tingling sensation.	Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Refer for medical attention .

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 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 DANGER Flammable solid Harmful if swallowed or in contact with skin Causes skin irritation Causes serious eye damage May cause respiratory irritation Very toxic to aquatic life with long lasting effects Transportation UN Classification UN Hazard Class: 4.1; UN Pack Group: III
STORAGE
Fireproof. Separated from food and feedstuffs and incompatible materials. See Chemical Dangers. Dry. Well closed. Keep in a well-ventilated room. Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing.
PACKAGING
Do not transport with food and feedstuffs. Marine pollutant.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance ODOURLESS WHITE CRYSTALS. Physical dangers Dust explosion possible if in powder or granular form, mixed with air. Chemical dangers Decomposes on heating and on burning. This produces toxic and corrosive fumes including hydrogen bromide and nitrogen oxides. Reacts with some metals, amines and alkaline compounds.	Formula: HOCH₂CBr(NO₂)CH₂OH / C₃H₆O₄BrN Molecular mass: 200 Melting point: 120-122°C Relative density (water = 1): 1.9 Solubility in water, g/100ml at 23°C: 28 (freely soluble) Vapour pressure, Pa at 20°C: <0.01 Flash point: 167°C Octanol/water partition coefficient as log Pow: 0.18

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion. Effects of short-term exposure The substance is corrosive 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 when dispersed. Effects of long-term or repeated exposure Repeated or prolonged contact may cause skin sensitization.
