AMMONIUM CHLORIDE

ICSC: 1051

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/m^3 (as TWA); 20 mg/m^3 (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

Boiling point: 520°C
Melting point (decomposes): 338°C
Density: 1.5 g/cm^3
Solubility in water, g/100 ml at 25°C: 28.3
Vapour pressure, kPa at 160°C: 0.13

ENVIRONMENTAL DATA

The substance is toxic to aquatic organisms.
