Important Data
|
Physical State; Appearance:
RED TO YELLOW OILY LIQUID
, WITH CHARACTERISTIC ODOUR.
TURNS BROWN ON Exposure TO AIR.
Physical Dangers:
Chemical Dangers:
The substance decomposes
on burning
producing toxic fumes of nitrogen oxides.
Reacts with acids, acid anhydrides, acid chlorides, chloroformates and strong oxidants.
Occupational Exposure Limits:
TLV: 0.1 ppm (as TWA) (A3) (skin) (ACGIH 1998).
OSHA PEL: TWA 0.5 mg/m3 skin
NIOSH REL: Ca 0.5 mg/m3 skin See Appendix A
NIOSH IDLH: Ca 50 mg/m3 See: 90040
|
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 be reached rather slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.
Effects of Short-Term Exposure:
The substance may cause effects on the blood
, resulting in
formation of methaemoglobin.
The effects may be delayed.
Medical observation is indicated.
See Notes.
Effects of Long-Term or Repeated Exposure:
This substance is possibly carcinogenic to humans.
