Controled concentration: Not established.
Permissible concentration(TWA)
Japan Association on Industrial Health: Not established.
ACGIH: Not established.
Facilities: Good general ventilation should be sufficient for
many cases.
Safety tools:
Respirator: Not needed in most cases.
Safety glasses: Not needed in most cases.
Safety gloves: Not needed in most cases.
Safety wears: Not needed in most cases.
Physical/Chemical Characteristics
Appearance: Golden lusted metal.
Specific gravity: 19.320
Melting point: 1064掳C
Boiling point: 2710掳C
Solubility: Insoluble in water under normal temperature.
Information on the dangerousness
Flash point: Not be flashed.
Ignition point: Not be ignited.
Explosion limits: Upper limit: Not be exploded.
Lower limit: Not be exploded.
Flammability: Noninflammable.
Spontaneous combustibility: Not combustible.
Oxidizability: No oxidizable.
Self-reactivity/Explosiveness: Not self-reactive/explosive.
Dust explosiveness: Not explosive by dust.
Stability/Reactivity: Gold wire has little chemical reactivity and does not
react with oxygen, sulfur and ordinary acid and base.
But it reacts with halogen, so is soluble in aqua
resia that releases chlorine. It is soluble in the
