PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID. TURNS DARK RED ON EXPOSURE TO AIR AND LIGHT.

PHYSICAL DANGERS:
The vapour mixes well with air, explosive mixtures are formed easily.

CHEMICAL DANGERS:
On combustion, forms nitrogen oxides. Reacts with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour 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 is irritating to the eyes.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the blood, resulting in the formation of methaemoglobin.
