TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.		In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION

EXPOSURE
Inhalation	Cough. Sore throat.	Ventilation (not if powder), local exhaust, or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	Redness.	Protective gloves.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes	Redness. Pain.	Safety spectacles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion	Nausea. Sore throat. Vomiting.	Do not eat, drink, or smoke during work.	Rinse mouth. Give plenty of water to drink. Rest. Refer for medical attention.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Sweep spilled substance into containers. Wash away remainder with plenty of water. (Extra personal protection: P2 filter respirator for harmful particles).	Xn Symbol R: 22-36 S: (2-)22

EMERGENCY RESPONSE	STORAGE
NFPA Code: H 1; F 0; R 0; Transport Emergency Card: TEC (R)-90G02	Separated from ammonium nitrate, potassium chlorate. Dry.

IMPORTANT DATA

Physical State; Appearance
ODOURLESS, COLOURLESS TO WHITE, HYGROSCOPIC SOLID IN VARIOUS FORMS.

Chemical dangers
The substance decomposes on heating producing toxic and irritating fumes (nitrogen oxides, ammonia and hydrogen chloride). The solution in water is a weak acid. Reacts violently with ammonium nitrate and potassium chlorate causing fire and explosion hazard. Attacks copper and its compounds.

Occupational exposure limits
TLV (as fume): 10 mg/m³ (as TWA);
20 mg/m³ (as STEL) (ACGIH 1998).
MAK not established.

Routes of exposure
The substance can be absorbed into the body by inhalation of its dust or fume and by ingestion.

Inhalation risk
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly.

Effects of short-term exposure
The substance irritates the eyes, the skin and the respiratory tract.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 520°C Melting point (decomposes): 338°C Density: 1.5 g/cm³ Solubility in water, g/100 ml at 25°C: 28.3 Vapour pressure, kPa at 160°C: 0.13	The substance is toxic to aquatic organisms.
