CRYSTALS.
Physical Dangers:
Dust explosion possible if in powder or granular form, mixed with air.
Chemical Dangers:
Reacts
violently with
acid anhydrides
,
acid chlorides
,
strong bases
and
strong oxidants
.
Occupational Exposure Limits:
TLV not established.
MAK: (Inhalable fraction) 5 mg/m3
Peak limitation category: I(1);
photosensitization (SP);

(DFG 2005).
|
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 nuisance-causing concentration of airborne particles can, however, be reached quickly.
Effects of Short-Term Exposure:
The substance
is irritating to
the eyes,
the skin
and
the respiratory tract.
Effects of Long-Term or Repeated Exposure:
Repeated or prolonged contact may cause skin sensitization.
