Handling and Storage
-
Handling: Avoid contact with skin and eyes. Use under adequate ventilation. Handle away from light and organic materials
-
Storage: Store in a tightly sealed container in a cool, dry, and well-ventilated area. Protect from light and incompatible substances (e.g., acids, reducing agents)
Environmental Considerations
Silver nitrate is very toxic to aquatic organisms and may cause long-term environmental effects. Prevent spills or release into sewers, waterways, or soil.
