	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Combustible. Finely dispersed particles form explosive mixtures in air.	NO open flames. Prevent deposition of dust. Closed system, dust explosion-proof electrical equipment and lighting.	Use water, powder, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

PREVENT DISPERSION OF DUST!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation		Avoid inhalation of dust. Use local exhaust and breathing protection.	Fresh air, rest.
Skin		Protective gloves.	Rinse and then wash skin with water and soap.
Eyes	Redness.	Wear safety goggles or eye protection in combination with breathing protection if powder.	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. Remove airborne particles with fine water spray.	According to UN GHS Criteria No hazard classification according to GHS criteria Transportation UN Classification
STORAGE
Separated from strong oxidants and strong acids.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS-TO-WHITE ODOURLESS CRYSTALLINE 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 heating. This produces irritating fumes. Reacts violently with strong oxidants and strong acids. This generates explosion hazard.	Formula: C₅H₁₂O₁₄ / C(CH₂OH)₄ Molecular mass: 136.2 Boiling point at 4kPa: 276°C Melting point: 260°C Relative density (water = 1): 1.4 Solubility in water, g/100ml at 25°C: 2.5 Vapour pressure, Pa at 20°C: 0.013 Relative vapour density (air = 1): 4.7 Flash point: 240°C o.c. Auto-ignition temperature: 390-490°C Octanol/water partition coefficient as log Pow: -1.69
