HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Not combustible. Combustible if powdered.     
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
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
PACKAGING & 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.

GHS Classification
 

EMERGENCY RESPONSE SAFE STORAGE
  Separated from ammonia, strong hydrogen peroxide solutions and strong acids. 

IMPORTANT DATA
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. 

Occupational exposure limits
MAK: 0.1 mg/m³; (DFG 1996). 

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 discolouration of the eyes, nose, throat and skin (argyria/argyrosis). 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
