FIRE FIGHTING
FIRE Not combustible, except as powder.


EXPLOSION


EXPOSURE
PREVENT DISPERSION OF DUST!

 •INHALATION
Local exhaust or breathing protection.
Fresh air, rest.
 •SKIN
Protective gloves.
Rinse skin with plenty of water or shower.
 •EYES
Safety spectacles, or eye protection in combination with breathing protection if powder.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
 •INGESTION
Do not eat, drink, or smoke during work.

SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment.
Separated from ammonia, strong hydrogen peroxide solutions, strong acids.

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).
