Physical Dangers:
Chemical Dangers:
Reacts violently with with aluminium and magnesium powders, and with chlorinated rubber on heating
causing fire and explosion hazard.
Occupational Exposure Limits:
TLV: (as respirable fraction) 2 mg/m3 as TWA; (ACGIH 2004). TLV: (as respirable fraction) 10 mg/m3 as STEL; (ACGIH 2004).
MAK: (as fume) 1 mg/m3, Respirable fraction;

Routes of Exposure:
The substance can be absorbed into the body
by inhalation of its aerosol
and
by ingestion.
Inhalation Risk:
A harmful concentration of airborne particles can be reached quickly especially for zinc oxide fume particles.
Effects of Short-Term Exposure:
Inhalation of fumes may cause metal fume fever.
The substance as a fume
is irritating to
the respiratory tract
.
The effects may be delayed.
See Notes.
