IMPORTANT DATA

Physical State; Appearance
WHITE POWDER

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; Peak limitation category: I(1); (DFG 2003).

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.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Melting point: 1975°C Density: 5.6 g/cm³ Solubility in water: none

NOTES

The symptoms of metal fume fever do not become manifest until a few hours have passed.
Card has been partly updated in October 2004. See sections Occupational Exposure Limits, EU classification, Emergency Response.
