Eye Contact: Rinse eyes thoroughly with water for at least 15 minutes, remove contact lenses if present, get medical help right away
Ingestion: Rinse mouth, do not induce vomiting, give water only if conscious, get emergency medical assistance
Important Symptoms and Effects: Acute poisoning, burns, respiratory distress, vomiting, abdominal pain, potential long-term organ effects
Suitable Extinguishing Media: Use dry chemical, CO2, or foam extinguishers; avoid using water directly on chemical fires
Hazardous Combustion Products: Produces toxic fumes including arsenic oxides and silver oxides
Special Protective Equipment For Firefighters: Use self-contained breathing apparatus and full protective clothing
Specific Hazards: Heating releases toxic gases, risk of strong exothermic reaction with incompatible substances
Firefighting Precautions: Isolate area, evacuate personnel, do not breathe fumes or smoke, use non-sparking tools
Personal Precautions: Evacuate area, use appropriate personal protective equipment, avoid dust formation
Environmental Precautions: Prevent run-off to drains, sewers, and natural water systems
Methods For Containment and Clean Up: Sweep up with non-sparking tools, collect in sealable, labeled containers for safe disposal, ventilate spill area, wash area thoroughly after cleanup
Handling: Work in well-ventilated area, use appropriate personal protection, avoid ingestion and inhalation of dust, wash hands and clothing after handling, keep away from food, children, and pets
Storage: Store in tightly sealed, labeled containers in a cool, dry, well-ventilated space, keep away from incompatible materials such as acids and strong oxidizers, protect from moisture and heat
Incompatible Materials: Strong acids, strong bases, reducing agents, oxidizing agents
Storage Temperature: Room temperature, away from direct sunlight
Control Parameters: Arsenic compounds threshold limit values (TLV) typically 0.01 mg/m3; check local regulatory exposure limits
Engineering Controls: Use fume hoods, local exhaust ventilation, containment systems to prevent dust exposure
Personal Protective Equipment (PPE): Chemical safety goggles, gloves (nitrile or neoprene), laboratory coat or chemical-resistant apron, respiratory protection (P100/HEPA full face mask) for dust or aerosol exposure
Hygiene Measures: Wash thoroughly after handling, do not eat or drink near the chemical, launder contaminated clothing before reuse

Routes of Exposure: Inhalation, ingestion, skin absorption
Acute Effects: Symptoms include severe gastrointestinal pain, vomiting, diarrhea, convulsions, and cardiac irregularities; ingestion can be fatal
Chronic Effects: Prolonged exposure linked to cancer (confirmed human carcinogen, IARC Group 1), peripheral neuropathy, liver and kidney damage, possible reproductive toxicity
LD50/LC50 Values: Arsenic(III) compounds (oral, rat): LD50 ≈ 15–22 mg/kg; silver compounds: variable and depends on solubility, but both are highly toxic
Skin and Eye Irritation: Causes severe burns and damage
Carcinogenicity: Contains arsenic, known human carcinogen
Sensitization: May cause allergic skin reaction in sensitive individuals
Aquatic Toxicity: Highly toxic to aquatic organisms; causes long-term adverse effects in aquatic environments
Persistence and Degradability: Persistent, bioaccumulates in soils and sediments
Bioaccumulative Potential: High, particularly arsenic component
Mobility in Soil: Low solubility, but contamination risk in case of spills
Other Adverse Effects: Toxic to birds, mammals, and microorganisms; interferes with key biological processes
Waste Disposal Methods: Treat as hazardous waste, follow all federal, state, and local regulations; use a licensed chemical disposal contractor
