Flammable Limits: Upper: N/A Lower: N/A


Extinguishing Media: Carbon dioxide, extinguishing powder or water spray. Fight larger fires with water spray or alcohol resistant foam.

Special Fire Fighting Procedures: Firefighters must wear full face, self-contained breathing apparatus with full protective clothing to prevent contact with skin and eyes. Fumes from fire are hazardous. Isolate runoff to prevent environmental pollution.


Unusual Fire & Explosion: May emit toxic fumes of hydrogen chloride and silver oxide if involved in a fire.






Effects of Exposure:


              To the best of our knowledge the chemical, physical and toxicological properties of silver chloride have not been thoroughly investigated and recorded.


              The absorption of silver compounds into the circulation and the subsequent deposition of the reduced silver in various tissues of the body may result in the production of a generalized greyish pigmentation of the skin and mucous membranes - a condition known as argyria. The introduction of fine particles of silver through breaks in the skin produces a local pigmentation at the site of the injury. These compounds may be irritating to the skin and mucous membranes. (Sax, Dangerous Properties of Industrial Materials).


              Chlorides vary widely. Sodium chloride (table salt) has very low toxicity, while carbonyl chloride (phosgene) is lethal in small doses (Sax, Dangerous Properties of Industrial Materials, eighth edition).


Acute and Chronic Effects:


Inhalation: Repeated overexposure can cause mild chronic bronchitis. Repeated exposure can cause permanent blue-gray discoloration of the nose/throat membranes.

Ingestion: No data

Skin: Repeated exposure can cause permanent blue-gray discoloration of the skin. Repeated skin contact with silver compounds has been found to cause allergic reactions in a few apparently sensitive persons, including (skin inflammation) and hypersensitivity.

Eye: Repeated exposure can cause permanent blue-gray discoloration of the eyes.


Medical Conditions Generally Aggravated by Exposure: Acute overexposure to dust may aggravate pre-existing chronic lung diseases.

Carcinogenicity: NTP: No           IARC: No          OSHA: No 



INHALATION: Supply fresh air. If required, provide artificial respiration. Keep patient warm. Seek immediate medical advice.

INGESTION: Seek medical treatment.

SKIN: Rinse affected area with flowing water, then wash with soap or detergent and water. Seek immediate medical advice.

EYE: Rinse opened eye for several minutes under running water. Then consult a doctor.






Stability: Stable if used and stored according to specifications.


Conditions to Avoid: Light, extreme heat. Exposure to light slowly releases silver and chlorine (accumulation of chlorine in an enclosed space could be hazardous to person entering area-highly irritating and corrosive to tissues).

Incompatibilities (Materials to Avoid): Aluminum, ammonium hydroxide, bromine trifluoride, alkali metals, sodium peroxide-charcoal, acetylene.


Hazardous Decomposition Products: Hydrogen chlorides.

Hazardous Polymerization: Will not occur






Steps to be Taken in Case Material is Released or Spilled: Wear appropriate respiratory and protective equipment specified in section VIII. Isolate spill area and provide ventilation. Scoop or vacuum up spill using a high efficiency particulate absolute (HEPA) air filter and place in a closed container for proper disposal. Take care not to raise dust.


Waste Disposal Method: Dispose of in accordance with State, Federal and Local regulations.






Respiratory Protection: NIOSH/MSHA approved respirator when high concentrations are present.

Ventilation: Use local exhaust to maintain concentrations at or below PEL/TLV.


Protective Gloves: Impervious gloves.

Eye protection: Dust-proof safety goggles.


Other Protective Equipment: Protective gear suitable to prevent contamination.





Precautions to Be Taken in Handling and Storage: Avoid breathing dust. Use in well ventilated area. Avoid contact with eyes. Do not wear contact lenses. Avoid contact with skin, especially when cracked or irritated. Keep work area as dust-free as possible. Label in compliance with OSHA and NFPA requirements. Store in a cool dry place, keep tightly sealed when not in use. Read MSDS before using.


Keep Away from Incompatible Substances: Aluminum, ammonium hydroxide, bromine trifluoride, alkali metals, sodium peroxide-charcoal.


Other Precautions: Can ignite or explode on contact with incompatible substances. Silver may react with acetylene or ammonia to form shock sensitive compounds.


Work Practices: Implement engineering and work practice controls to reduce and maintain concentration of exposure at low levels. Use good housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before eating and smoking. Do not blow dust off clothing or skin with compressed air. Maintain eyewash capable of sustained flushing, safety drench shower and facilities for washing.
