Section 4. First Aid Measures
Eye ContactCheck for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at
least 15 minutes. Cold water may be used. Get medical attention.
Skin ContactIn case of contact, immediately flush skin with plenty of water. Cover the irritated skin with an emollient. Remove
contaminated clothing and shoes. Cold water may be used.Wash clothing before reuse. Thoroughly clean shoes
before reuse. Get medical attention.
Serious Skin ContactWash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek medical
attention.
InhalationIf inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get
medical attention.
Serious InhalationNot available.

Hazards
Section 6. Accidental Release Measures
Small SpillUse appropriate tools to put the spilled solid in a convenient waste disposal container. Finish cleaning by
spreading water on the contaminated surface and dispose of according to local and regional authority
requirements.
Large SpillUse a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water
on the contaminated surface and allow to evacuate through the sanitary system. Be careful that the product is not
present at a concentration level above TLV. Check TLV on the MSDS and with local authorities.

Section 7. Handling and Storage
PrecautionsKeep away from heat. Keep away from sources of ignition. Empty containers pose a fire risk, evaporate the
residue under a fume hood. Ground all equipment containing material. Do not breathe dust. Wear suitable
protective clothing. In case of insufficient ventilation, wear suitable respiratory equipment. If you feel unwell, seek
medical attention and show the label when possible. Avoid contact with skin and eyes. Keep away from
incompatibles such as acids.
StorageHygroscopic. Light sensitive. Store light-resistant container. Keep container tightly closed. Keep container in a
cool, well-ventilated area. Do not store above 24°C (75.2°F).
Section 8. Exposure Controls/Personal Protection
Engineering ControlsUse process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below
recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to
airborne contaminants below the exposure limit.
Personal ProtectionSplash goggles. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent.
Gloves.
Personal Protection in Case of Splash goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing apparatus should be used
a Large Spillto avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist
BEFORE handling this product.

Toxicity to Animals
Special Remarks onMay cause cancer based on animal data. However, at the timeof this review, no studies were found on the
Chronic Effects on Humanspossible carcinogenic activity of silver compounds in humans.
Special Remarks on otherAcute Potential Health Effects:
Toxic Effects on HumansSkin: May cause skin irritation.
Eyes: May cause mechanical eye irritation.
Inhalation: May cause respiratory tract irritation. Expoures above TLV may result in acculmulation of silver in the
body (argyria) Symptoms may include a permanent blue-gray pigmentation of the skin, mucous membranes, and
eyes.
Ingestion: May be harmful if swallowed. large doses may result in silver poisong, which may show symptoms of
gastroenteritis (gastrointestinal tract irritation), spasms, and skin discoloration.
Prolonged or repeated inhalation, application, or ingestion of silver compounds may cause a permanent bluish
discoloration of the skin and mucous membranes, and may also affect blood, and liver.
