EXPLOSION


EXPOSURE
PREVENT GENERATION OF MISTS! AVOID EXPOSURE OF (PREGNANT) WOMEN!

•INHALATION Drowsiness. Headache. Nausea. Unconsciousness.

PHYSICAL STATE; APPEARANCE:
COLOURLESS, HYGROSCOPIC, VISCOUS LIQUID.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
On combustion, forms toxic gases (nitrogen oxides). The substance decomposes on heating at 180°C producing ammonia , water , carbon monoxide and hydrogen cyanide . Reacts withoxidants. Attacks metals such as aluminium, iron, copper and natural rubber.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 10 ppm as TWA; (skin); (ACGIH 2004).
OSHA PEL†: none
NIOSH REL: TWA 10 ppm (15 mg/m3) skin
NIOSH IDLH: N.D. See: IDLH INDEX


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion.

INHALATION RISK:
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes and the skin . The substance may cause effects on the central nervous system .

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Animal tests show that this substance possibly causes toxic effects upon human reproduction.

PHYSICAL
PROPERTIES

Boiling point (decomposes): 210°C
Melting point: 2.5°C
Relative density (water = 1): 1.13
Solubility in water:
very good
Vapour pressure, Pa at 20°C: about 2
Relative vapour density (air = 1): 1.6
Flash point: 154°C o.c.
