First-aid measures

Inhalation: Move to fresh air. Treat symptomatically. Get medical attention if symptoms occur.
Eyes: In case of contact with eyes, flush immediately with plenty of water and seek medical attention.
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:
Symptoms: The absorption of this product into the body may lead to the formation of methemoglobin that,
in sufficient concentration, causes cyanosis.
Treatment: Since reversion of methemoglobin to hemoglobin occurs spontaneously after termination of
exposure, moderate degrees of cyanosis need to be treated only by supportive measures. Thorough
cleansing of the entire contaminated area of the body, including scalp and nails, is of utmost importance. If
cyanosis is severe,

Fire-fighting measures

Extinguishing Media: Flood with water.
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.

Accidental release measures

Personal precautions: See Section 8 for recommendations on the use of personal protective equipment.
Environmental precautions: Prevent spillage from entering drains. Collect up and put in a suitable container.
Clean surface thoroughly to remove residual contamination.
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.
Prevention of Fire and Explosion: Keep away from combustible material. Remove and wash contaminated
clothing promptly.
Storage: Cool conditions (5 - 30°C). Keep container closed. Keep away from incompatible substances (see
Incompatibility section.)
Ventilation: Match ventilation rates to conditions of use so as not to exceed any applicable exposure limits (see
Section 8). Good general ventilation of 10 or more room volumes per hour in the work area is recommended.

Exposure controls / personal protection

Occupational exposure controls
Chemical Name Regulatory List Value Type Value
Silver nitrate 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.
Respiratory protection: In case of insufficient ventilation, wear personal respiratory protection
designed to protect against both aerosols and acid gas.
Eye protection: Wear safety glasses with side shields (or goggles) and a face shield.
Skin and body protection: Wear impervious gloves and protective clothing appropriate for the risk of
Recommended Decontamination Facilities: Safety shower, eye wash, washing facilities.

Stability and reactivity

Stability: Stable.
Incompatibility: Material can react violently with combustible materials, reducing agents, aqueous ammonia.
Hazardous decomposition products: oxides of nitrogen. Hazardous Polymerization: Will not occur.

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: If thoroughly cleaned, preferably by rinsing at least three times with small quantities of
water, waste product packaging may be consigned for recovery or disposal as non hazardous waste. The
European Waste Catalogue Code is 15 01 02 plastic packaging.
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.
