Section 3. Hazards Identification Potential Acute Health Effects Potential Chronic Health Effects Extremely hazardous in case of ingestion. Hazardous in case of skin contact (irritant), of eye contact (irritant), of inhalation. Severe over-exposure can result in death. Extremely hazardous in case of ingestion. Hazardous in case of skin contact (irritant), of eye contact (irritant), of inhalation. CARCINOGENIC EFFECTS: MUTAGENIC EFFECTS: TERATOGENIC EFFECTS: DEVELOPMENTAL TOXICITY: The substance is toxic to blood, lungs, mucous membranes. Repeated or prolonged exposure to the substance can produce target organs damage. Repeated exposure to an highly toxic material may produce general deterioration of health by an accumulation in one or many human organs.

2 Silver cyanide Page Number: 2 Section 4. First Aid Measures Eye Contact Skin Contact Serious Skin Contact Inhalation Check for and remove any contact lenses. Immediately flush eyes with running water for at least 5 minutes, keeping eyelids open. Cold water may be used. Do not use an eye ointment. Seek medical attention. After contact with skin, wash immediately with plenty of water. Gently and thoroughly wash the contaminated skin with running water and non-abrasive soap. Be particularly careful to clean folds, crevices, creases and groin. Cover the irritated skin with an emollient. If irritation persists, seek medical attention. Wash contaminated clothing before reusing. Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek immediate medical attention. Allow the victim to rest in a well ventilated area. Seek immediate medical attention. Serious Inhalation Ingestion Serious Ingestion Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or waistband. If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth resuscitation. Seek medical attention. Do not induce vomiting. Examine the lips and mouth to ascertain whether the tissues are damaged, a possible indication that the toxic material was ingested; the absence of such signs, however, is not conclusive. Loosen tight clothing such as a collar, tie, belt or waistband. If the victim is not breathing, perform mouth-to-mouth resuscitation. Seek immediate medical attention. Section 5. Fire and Explosion Data Flammability of the Product Auto-Ignition Temperature Flash Points Flammable Limits Products of Combustion Fire Hazards in Presence of Various Substances May be combustible at high temperature. Some metallic oxides. Slightly flammable to flammable in presence of oxidizing materials. Explosion Hazards in Presence of Various Substances Risks of explosion of the product in presence of mechanical impact: Risks of explosion of the product in presence of static discharge: Slightly explosive to explosive in presence of oxidizing materials. Fire Fighting Media and Instructions Fire Hazards Explosion Hazards SMALL FIRE: Use DRY chemical powder. LARGE FIRE: Use water spray, fog or foam. Do not use water jet. Section 6. Accidental Release Measures Small Spill Large Spill Use appropriate tools to put the spilled solid in a convenient waste disposal container. Use a shovel to put the material into a convenient waste disposal container. Be careful that the product is not present at a concentration level above TLV. Check TLV on the MSDS and with local authorities.

3 Silver cyanide Page Number: 3 Section 7. Handling and Storage Precautions Storage Keep locked up Keep 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 ingest. Do not breathe dust. Wear suitable protective clothing In case of insufficient ventilation, wear suitable respiratory equipment If ingested, seek medical advice immediately and show the container or the label. Avoid contact with skin and eyes Keep container dry. Keep in a cool place. Ground all equipment containing material. Keep container tightly closed. Keep in a cool, well-ventilated place. Highly toxic or infectious materials should be stored in a separate locked safety storage cabinet or room. Section 8. Exposure Controls/Personal Protection Engineering Controls Personal Protection Personal Protection in Case of a Large Spill Exposure Limits Use 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. Splash goggles. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent. Gloves. Splash goggles. Full suit. Dust respirator. Boots. Gloves. A self contained breathing apparatus should be used to avoid inhalation of the product. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling this product. TWA: 0.0 (mg/m 3 ) from ACGIH Consult local authorities for acceptable exposure limits. Section 9. Physical and Chemical Properties Physical state and appearance Solid. (Powdered solid.)
