IMPORTANT DATA
Physical State; Appearance Routes of exposure
ODOURLESS GREY TO BLUE POWDER. The substance can be absorbed into the body by inhalation and
by ingestion.
Physical dangers
Inhalation risk
Dust explosion possible if in powder or granular form, mixed with
air. If dry, it can be charged electrostatically by swirling, Evaporation at 20/C is negligible; a harmful concentration of
pneumatic transport, pouring, etc. airborne particles can, however, be reached quickly when
dispersed.
Chemical dangers
Effects of short-term exposure
Upon heating, toxic fumes are formed. The substance is a
strong reducing agent and reacts violently with oxidants. Reacts Inhalation of fumes may cause metal fume fever. The effects
with water and reacts violently with acids and bases forming may be delayed.
flammable/explosive gas (hydrogen - see ICSC0001). Reacts
violently with sulfur, halogenated hydrocarbons and many other Effects of long-term or repeated exposure
substances causing fire and explosion hazard. Repeated or prolonged contact with skin may cause dermatitis.
Occupational exposure limits
TLV not established.
PHYSICAL PROPERTIES
Boiling point: 907/C Solubility in water: reaction
Melting point: 419/C Vapour pressure, kPa at 487/C: 0.1
Relative density (water = 1): 7.14 Auto-ignition temperature: 460/C
ENVIRONMENTAL DATA
NOTES
Zinc may contain trace amounts of arsenic, when forming hydrogen, may also form toxic gas arsine (see ICSC0001 and ICSC0222).
Reacts violently with fire extinguishing agents such as water, halons, foam and carbon dioxide.
The symptoms of metal fume fever do not become manifest until several hours later.
Rinse contaminated clothes (fire hazard) with plenty of water.
Card has been partly updated in April 2005. See sections EU classification, Emergency Response.
