IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS TO YELLOW LIQUID, WITH CHARACTERISTIC ODOUR. TURNS DARK ON EXPOSURE TO AIR.

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic fumes including nitrogen oxides, hydrogen chloride - see ICSC0163.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: BEI issued (ACGIH 2004).
MAK: IIb (not established but data is available) skin absorption (H); (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, 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 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes. The substance may cause effects on the blood, resulting in the formation of methaemoglobin. Medical observation is indicated. The effects may be delayed.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
