CAS #: 557-05-1

EC Number: 209-151-9

	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. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust. Prevent build-up of electrostatic charges (e.g., by grounding).	Use water spray, powder, foam, carbon dioxide.

PREVENT DISPERSION OF DUST!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough.	Avoid inhalation of dust and mist.	Fresh air, rest. Refer for medical attention.
Skin			Rinse skin with plenty of water or shower.
Eyes		Wear safety goggles.	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.

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 Transportation UN Classification
STORAGE

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance WHITE FINE SOFT POWDER. Physical dangers Dust explosion possible if in powder or granular form, mixed with air. If dry, it can be charged electrostatically by swirling, pneumatic transport, pouring, etc. Chemical dangers Decomposes on burning. This produces irritating and toxic fumes including zinc oxide.	Formula: C₃₆H₇₀O₄Zn / Zn(C₁₈H₃₅O₂)₂ Molecular mass: 632.3 Melting point: 130°C Density: 1.1 g/cm³ Solubility in water: none Flash point: 277°C o.c. Auto-ignition temperature: 420°C Explosive limits, vol% in air: 20-? Octanol/water partition coefficient as log Pow: 1.2
