CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. Wash away remainder with plenty of water.
According to UN GHS Criteria
Transportation UN Classification
Separated from ammonium nitrate and potassium chlorate. Dry.
PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance ODOURLESS COLOURLESS-TO-WHITE HYGROSCOPIC SOLID IN VARIOUS FORMS.
Chemical dangers Decomposes on heating. This produces 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. This generates fire and explosion hazard. Attacks copper and its compounds.
Molecular mass: 53.5
Boiling point: 520°C Decomposes at 338°C Density: 1.5 g/cm³ Solubility in water, g/100ml at 25°C: 28.3 Vapour pressure, kPa at 160°C: 0.13
EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation of dust or fume and by ingestion.
Effects of short-term exposure The substance is irritating to the eyes, skin and respiratory tract.
Inhalation risk Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly.
Effects of long-term or repeated exposure
OCCUPATIONAL EXPOSURE LIMITS
TLV: 10 mg/m3, as TWA; 20 mg/m3 as STEL
The substance is toxic to aquatic organisms.
