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: use appropriate extinguishing media.
EXPLOSION


EXPOSURE


 •INHALATION
Local exhaust or breathing protection.
Fresh air, rest.
 •SKIN
Protective gloves.
Rinse skin with plenty of water or shower.
 •EYES Redness. Pain.

PHYSICAL STATE; APPEARANCE:
COLOURLESS TO WHITE HYGROSCOPIC CRYSTALLINE POWDER

PHYSICAL DANGERS:


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).
OSHA PEL: TWA 15 mg/m3 (total) TWA 5 mg/m3 (resp)
NIOSH REL: TWA 10 mg/m3 (total) TWA 5 mg/m3 (resp)
NIOSH IDLH: 1500 mg/m3 See: 7773060


ROUTES OF EXPOSURE:


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 .

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Boiling point (decomposes): 160°C
Melting point: 131°C
Relative density (water = 1): 1.8
Solubility in water: very good
