ICSC: 0456

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
YELLOW-BROWNISH VISCOUS LIQUID.

CHEMICAL DANGERS:
On combustion, forms toxic and corrosive gases (nitrogen oxides). Reacts violently with strong oxidants. Attacks many plastics.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.

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

INHALATION RISK:
No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the red blood cells, resulting in formation of methaemoglobin. The effects may be delayed.

PHYSICAL PROPERTIES

Solubility in water: none
Relative vapour density (air = 1): 4.7

Relative density of the vapour/air-mixture at 20°C (air = 1): 1.0
Flash point: 83°C
Octanol/water partition coefficient as log Pow: 2.61

ENVIRONMENTAL DATA

NOTES

Depending on the degree of exposure, periodic medical examination is suggested. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. Card has been partly updated in October 2005. See section Emergency Response.
