Important Data
|
Physical State; Appearance:
ODOURLESS
,
COLOURLESS
OR WHITE CRYSTALS.
Physical Dangers:
Chemical Dangers:
The substance decomposes
on heating
producing
toxic fumes
including
nitrogen oxides
.
The substance is a strong oxidant and reacts violently with combustible and reducing materials.
Reacts with incompatible substances such as acetylene, alkalies, halides and many other compounds
causing fire and explosion hazard.
Attacks some forms of plastics, rubber and coatings.
Occupational Exposure Limits:
TLV: (as Ag) 0.01 mg/m3 as TWA; (ACGIH 2008).
MAK: (Inhalable fraction) 0.01 mg/m3
Peak limitation category: I(2); Pregnancy risk group: D;
(DFG 2008).
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its aerosol
and
by ingestion.
Inhalation Risk:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.
Effects of Short-Term Exposure:
The substance
is corrosive to
the eyes,
the skin
and
the respiratory tract.
Corrosive on ingestion.
The substance may cause effects on the
blood
, resulting in
formation of methaemoglobin.
The effects may be delayed.
Medical observation is indicated.
Effects of Long-Term or Repeated Exposure:
The substance may have effects on the
blood
, resulting in
formation of methaemoglobin.
Inhalation or ingestion can lead to generalized argyria, grey discolouration of the eyes and the skin and brown fingernails.
