Important Data
|
Physical State; Appearance:
WHITE METAL,
TURNS DARK ON Exposure TO OZONE, HYDROGEN SULFIDE OR SULFUR.
Physical Dangers:
Chemical Dangers:
Shock-sensitive compounds are formed with acetylene.
Reacts with acids
causing fire hazard.
Contact with strong hydrogen peroxide solution will cause violent decomposition to oxygen gas.
Contact with ammonia may cause formation of compounds that are explosive when dry.
Occupational Exposure Limits:
TLV (metal): 0.1 mg/m3 (ACGIH 1997).
EU OEL: 0.1 mg/m3 as TWA (EU 2000).
OSHA PEL: TWA 0.01 mg/m3
NIOSH REL: TWA 0.01 mg/m3
NIOSH IDLH: 10 mg/m3 (as Ag) See: IDLH INDEX
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation and
by ingestion.
Inhalation Risk:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.
Effects of Short-Term Exposure:
Inhalation of high amounts of metallic silver vapours may cause lung damage with pulmonary oedema.
Effects of Long-Term or Repeated Exposure:
The substance may cause a grey-blue discoloration of the eyes, nose, throat and skin (argyria/argyrosis).
