	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Not combustible.		In case of fire in the surroundings, use appropriate extinguishing media.


	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough.	Use local exhaust.	Fresh air.
Skin
Eyes	Redness.	Wear safety spectacles.	Rinse with plenty of water (remove contact lenses if easily possible).
Ingestion	No acute symptoms expected.		Give one or two glasses of water to drink.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water.	According to UN GHS Criteria No hazard classification according to GHS criteria Transportation UN Classification
STORAGE
Separated from incompatible materials. See Chemical Dangers.

SODIUM BICARBONATE

ICSC: 1044

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance FINE WHITE CRYSTALLINE POWDER. Physical dangers Chemical dangers The solution in water is a weak base. Reacts with acids, sodium-potassium alloy, some metals and ammonium compounds. This produces heat and carbon dioxide (see ICSC 0021). Decomposes on heating above 50°C . This produces sodium oxides, carbon dioxide (see ICSC 0021), water and irritating fumes. See ICSC 1135.	Formula: NaHCO₃ Molecular mass: 84.0 Decomposes: see Notes. Density: 2.1 g/cm³ Solubility in water, g/100ml at 20°C: 9.3
