Administrative data
First-aid measures
Tak off all contaminated clothing.
Inhalation: Move to fresh air. Treat symptomatically. If breathing is difficult, give oxygen. If no breathing, give artificial respiration. Get medical attention if symptoms occur.
Eyes: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and
lower eyelids. Continue rinsing process with eye rinsing solution. Get medical aid immediately (caustic burn of the eyes). Do NOT allow victim to rub eyes or keep eyes closed. Initiate further treatment with ophtalmic personnel.
Skin: Immediately flush with plenty of water for at least 15 minutes and wash using soap. Remove contaminated
clothing and shoes. Get medical attention if symptoms occur. Wash contaminated clothing before reuse. Destroy
contaminated shoes.
Ingestion: Do NOT induce vomiting. Give victim a glass of water. Get medical attention immediately. Never give
anything by mouth to an unconscious person.
Notes to physician: Treat symptomatically and supportively
Fire-fighting measures
General Information: Strong oxidizer. Contact with other material may cause fire. Wear appropriate
protective clothing to prevent contact with skin and eyes. Wear a self-contained breathing apparatus
(SCBA) to prevent contact with thermal decomposition products.
Extinguishing Media: For small fires, use dry chemical, carbon dioxide, water spray or alcohol-resistant foam.
Special Fire-Fighting Procedures: Wear self-contained breathing apparatus and protective suit. Fire or
excessive heat may produce hazardous decomposition products.
Hazardous Combustion Products: None (see also Hazardous Decomposition Products section).
Unusual Fire and Explosion Hazards: Oxidizer Greatly increases the burning rate of combustible materials.
Special exposure hazards: this material increases the risk of fire and may aid combustion. Contact with combustible material may cause fire.
Water used to extinguish fire should not enter drainage systems, soil or stretches of water. Ensure there are sufficient retaining facilities for water used to extinguish fire. Contaminated fire-extinguishing water must be disposed of in accordance with the regulations issued by the appropriate local authorities.
Accidental release measures
Personal precautions: See below for recommendations on the use of personal protective equipment.
Spills/Leaks: Vacuum or sweep up material and place into a suitable disposal container. Avoid generating
dusty conditions and prevent wind dispersal. Remove all sources of ignition.
Environmental precautions: Prevent spillage from entering drains, sewage water, soil stretches of water, groundwater. Collect up and put in a suitable container.
Clean surface thoroughly to remove residual contamination. Carefully scoop up spilled material and use a non-sparking or explosion proof means to transfer material to an appropriate container for disposal or recovery.
Waste disposal: Contaminated absorbent should be disposed of in accordance with local regulations.
Handling and storage
Personal precautions: Do not get in eyes, on skin, or on clothing. Do not breathe dust at concentrations
greater than the exposure limits. Use only with adequate ventilation. Wash thoroughly after handling.
Handling: always close container tightly after removal of product. Ensure suitable suction/aeration at the work place and with operational machinery
Storage: Keep away from sources of ignition. Do not store near combustible materials. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from incompatible substances.
Ventilation: Match ventilation rates to conditions of use so as not to exceed any applicable exposure limits. Good general ventilation of 10 or more room volumes per hour in the work area is recommended.

Exposure controls / personal protection
Chemical Name Regulatory List Value Type Value
Silver Oxide EH40 OES Time Weighted 0.01 mg/m3
Average (TWA): Expressed as Ag
EU ELV Time Weighted 0.01 mg/m3
Average (TWA): Expressed as Ag
Ventilation: Use process enclosures, local exhaust ventilation, or other engineering controls to
maintain airborne levels below recommended exposure limits.
Personal Protective Equipment
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and
face protection regulations in 29 CFR 1910.133 or European Standard EN166.
Skin: Wear impervious gloves.
Clothing: Wear appropriate protective clothing to prevent skin exposure.
Respirators: Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN
149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded
or if irritation or other symptoms are experienced.
Recommended Decontamination Facilities: Safety shower, eye wash and washing facilities.
Stability and reactivity
Stability: Stable. Absorbs carbon dioxide from the air.
Thermal decomposition: >= 170°C
Incompatibility: Material can react violently with combustible materials, organic materials & reducing agents.
Reacts dangerously with ammonia. Grinding silver oxide with metal sulfides, selenium, sulfur, or phosphorus can
cause ignition. Hydrogen sulfide may ignite when in contact with silver oxide. Incompatible with hydrazines, amines,
sulfur, metal sulfides, and carbon monoxide.
Hazardous decomposition products: oxygen, silver fumes.
Hazardous Polymerization: Has not been reported
Disposal considerations
Waste material: Waste material is currently classified as hazardous under Council Directive 91/689/EEC. The
European Waste Catalogue Code is 06 03 13 Solid salts and solutions containing heavy metals. Dispose
according to the local regulations or guidelines that apply to the category of waste. Ensure the use of properly
authorised waste management companies.
Product containers: Waste material is currently classified as hazardous under Council Directive 91/689/EEC.
The European Waste Catalogue Code is 06 03 13 Solid salts and solutions containing heavy metals. Dispose
according to the local regulations or guidelines that apply to the category of waste. Ensure the use of properly
authorized waste management companies. Waste product packaging contaminated by residues of hazardous
contents should be consigned for disposal as hazardous waste. In this case, the European Waste Catalogue
Code is 15 01 10 packaging containing residues of or contaminated by dangerous substances.
