IMPORTANT DATA
Physical State; Appearance Routes of exposure
COLOURLESS, HYGROSCOPIC TO WHITE SOLID IN The substance can be absorbed into the body by inhalation of its
VARIOUS FORMS aerosol.
Chemical dangers Inhalation risk
Heating may cause violent combustion or explosion. The Evaporation at 20/C is negligible; a harmful concentration of
substance decomposes on heating or producing toxic fumes airborne particles can, however, be reached quickly.
(nitrogen oxides.) The substance is a strong oxidant and reacts
with combustible and reducing materials. Effects of short-term exposure
The substance is irritating to the eyes, the skin and the respiratory
Occupational exposure limits tract. The substance may cause effects on the blood, resulting in
TLV not established. formation of methaemoglobin. Medical observation is indicated.
The effects may be delayed.
