	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Combustible. Finely dispersed particles form explosive mixtures in air.	NO open flames. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust.	Use water spray.

PREVENT DISPERSION OF DUST! STRICT HYGIENE!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation		Use local exhaust.	Fresh air, rest.
Skin		Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes	Redness. Pain.	Wear safety spectacles.	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. Give one or two glasses of water to drink. Refer for medical attention .

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
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. Do NOT let this chemical enter the environment. Personal protection: particulate filter respirator adapted to the airborne concentration of the substance.	According to UN GHS Criteria Transportation UN Classification
STORAGE
Well closed.

BENZOTRIAZOLE

ICSC: 1091

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance WHITE-TO-BROWN CRYSTALLINE 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 aniline and nitrobenzene. The solution in water is a weak acid. May explode on vacuum distillation.	Formula: C₆H₅N₃ Molecular mass: 119.1 Boiling point at 2 kPa: 204°C Sublimation point: 200°C Decomposes at 260°C Melting point: 98.5°C Density: 1.36 g/cm³ Solubility in water, g/100ml: 2 (moderate) Vapour pressure, Pa at 20°C: 5 Flash point: 190-195°C o.c. Auto-ignition temperature: 210°C

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. Effects of short-term exposure The substance is irritating to the eyes.	Inhalation risk Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly. Effects of long-term or repeated exposure Repeated or prolonged contact may cause skin sensitization.
