  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible. Combustible if powdered.           

 PREVENT DISPERSION OF DUST!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation   Use local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.  Rinse skin with plenty of water or shower. 
Eyes   Wear 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 refer for medical attention. 
Ingestion   Do not eat, drink, or smoke during work.   

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT let this chemical enter the environment. 

According to UN GHS Criteria

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
WHITE METAL. TURNS DARK ON EXPOSURE TO OZONE, HYDROGEN SULFIDE OR SULFUR. 

Physical dangers
 

Chemical dangers
Mixtures with acetylene are shock-sensitive. Reacts with acids. This generates fire hazard. Contact with strong hydrogen peroxide solution causes violent decomposition to oxygen gas. Contact with ammonia may cause formation of compounds that are explosive when dry. 

Formula: Ag
Atomic mass: 107.9
Boiling point: 2212°C
Melting point: 962°C
Relative density (water = 1): 10.5
Solubility in water: none 


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation and by ingestion. 

Effects of short-term exposure
Inhalation of high amounts of metallic silver vapours may cause lung damage with pulmonary oedema. 

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. 

Effects of long-term or repeated exposure
The substance may cause a grey-blue discolouration of the eyes, nose, throat and skin (argyria/argyrosis). 


Occupational exposure limits
TLV: 0.1 mg/m3, ppm, as TWA.
MAK: (inhalable fraction): 0.1 mg/m3; peak limitation category: II(8); pregnancy risk group: D.
EU-OEL: 0.1 mg/m3 as TWA 

ENVIRONMENT
This substance may be hazardous to the environment. Special attention should be given to aquatic organisms.
