Eye Contact: Immediately flush eyes with water for at least 15 minutes, lifting eyelids occasionally. Obtain medical attention without delay.
Skin Contact: Remove contaminated clothing, wash skin with soap and plenty of water. Seek medical help if irritation occurs or persists.
Ingestion: Rinse mouth, drink several glasses of water if conscious, do not induce vomiting. Get immediate medical assistance.
Inhalation: Move to fresh air, maintain breathing, give artificial respiration if breathing stops. Call a poison control center or doctor right away.
Most Important Symptoms: Nausea, vomiting, abdominal pain, diarrhea, confusion, muscle weakness, organ failure at high doses.
Advice for Medical Professionals: Treat symptomatically and supportively, monitor vital signs, consider chelation therapy for arsenic poisoning.
Suitable Extinguishing Media: Use dry chemical, carbon dioxide, foam, or water spray as appropriate for surrounding fire.
Specific Hazards: May emit toxic fumes of arsenic oxides and iron oxides under fire conditions.
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear.
Special Procedures: Avoid runoff to sewers or waterways, isolate hazard area, use water spray to cool containers exposed to fire.
Personal Protection: Evacuate unnecessary personnel, ventilate area, wear full protective clothing including gloves, goggles, and respirator.
Spill Clean-up: Avoid dust formation, sweep up and place in suitable closed containers for disposal. Prevent spillage from entering drains or water sources.
Environmental Precautions: Highly toxic to aquatic organisms. Notify authorities if product enters waterway.
Decontamination: Wash contaminated surfaces with plenty of water, collect waste water for proper disposal.
Safe Handling: Handle in a chemical fume hood whenever possible. Avoid generating dust, avoid all unprotected contact, ensure good ventilation.
Storage Conditions: Store in tightly closed, labeled containers in a cool, dry, well-ventilated area, away from incompatible substances including strong acids and bases.
Incompatibilities: Avoid contact with strong oxidizers, reducing agents, acids.
Hygiene Measures: Wash hands and face thoroughly after handling, remove contaminated clothing before entering eating areas.
Exposure Limits (OSHA/NIOSH): Arsenic compounds (as As): TWA 0.01 mg/m3 (OSHA, NIOSH); Iron compounds: no specific standard
Engineering Controls: Use only with adequate ventilation, local exhaust to control airborne concentrations.
Personal Protective Equipment: Wear chemical-resistant gloves, safety goggles, impervious clothing, suitable respiratory protection in case of insufficient ventilation.
Environmental Controls: Implement measures to prevent exposure to surrounding environment, use closed systems as much as possible.
