Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its vapour
and
through the skin
, also as a vapour!
Inhalation Risk:
A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance
is irritating to
the skin.
Inhalation of the vapours may cause pneumonitis.
The substance may cause effects on the central nervous systemandkidneys.
The effects may be delayed.
Medical observation is indicated.
Effects of Long-Term or Repeated Exposure:
The substance may have effects on the
central nervous system
and
kidneys
, resulting in irritability, emotional instability, tremor, mental and memory disturbances, speech disorders.
May cause inflammation and discoloration of the gums.
Danger of cumulative effects.
Animal tests show that this substance possibly causes toxic effects upon human reproduction.
