EC Number: 231-987-8

	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.		In case of fire in the surroundings, use appropriate extinguishing media.


	SYMPTOMS	PREVENTION	FIRST AID
Inhalation		Use local exhaust.	Fresh air, rest.
Skin		Protective gloves.	Rinse skin with plenty of water or shower.
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. Refer for medical attention .

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. Wash away remainder with plenty of water.	According to UN GHS Criteria Transportation UN Classification
STORAGE
Separated from strong oxidants, strong bases and strong acids. Keep in a well-ventilated room.

AMMONIUM PHOSPHATE DIBASIC

ICSC: 0217

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance ODOURLESS WHITE CRYSTALS OR POWDER. Physical dangers Chemical dangers Decomposes above 100°C . Decomposes on contact with strong bases. This produces toxic and corrosive fumes including ammonia, nitrogen oxides and phosphorus oxides. The solution in water is a weak base. Reacts vigorously with strong acids and strong oxidants. Gradually gives off ammonia on exposure to air.	Formula: (NH₄)₂HPO₄ Molecular mass: 132.1 Decomposes at 100°C Relative density (water = 1): 1.6 Solubility in water, g/100ml at 10°C: 57.5

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of its aerosol. 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 when dispersed, especially if powdered. Effects of long-term or repeated exposure
