AMMONIUM SULFAMATE ICSC: 1555
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS TO WHITE HYGROSCOPIC CRYSTALLINE POWDER

CHEMICAL DANGERS:
The substance decomposes on heating above 160°C producing ammonia, nitrogen oxides and sulfur oxides. The solution in water is a weak acid. Attacks mild steel. Contact with hot water may cause formation of large amounts of steam. Reacts with acids and strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 10 mg/m³ as TWA; (ACGIH 2004).
MAK: IIb, value not established but data is available (DFG 2004).
INHALATION RISK:
A harmful concentration of airborne particles can be reached quickly on spraying or when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes.

PHYSICAL PROPERTIES
Boiling point (decomposes): 160°C
Melting point: 131°C
Relative density (water = 1): 1.8
Solubility in water: very good
Vapour pressure, Pa at 20 °C: negligible
