Eye Contact: Rinse promptly with water for at least 15 minutes. Remove contact lenses if present. Seek medical attention immediately.
Skin Contact: Remove contaminated clothing. Wash skin thoroughly with soap and water. Get medical help if irritation occurs.
Inhalation: Move person to fresh air. Administer artificial respiration if breathing stops. Seek immediate medical care.
Ingestion: Rinse mouth with water. Do not induce vomiting unless instructed by medical personnel. Get emergency medical assistance.
Symptoms: Nausea, headache, dizziness, tremors, difficulty breathing, rash, kidney damage
Suitable Extinguishing Media: Use dry chemical, CO2, water spray, or foam. Do not use water jet.
Specific Hazards: Emits toxic fumes under fire, including mercury vapor, phenyl compounds, and carbon oxides. Fire run-off may contaminate water supply.
Protective Equipment for Firefighters: Full protective gear, self-contained breathing apparatus.
Advice for Firefighters: Control run-off water to prevent entry into soil, drains, or waterways. Remove containers if safe to do so.
Personal Precautions: Evacuate personnel to safe area. Prevent contact with skin and eyes. Use personal protective equipment.
Environmental Precautions: Prevent leak or spillage from entering drains, sewers, or waterways. Notify authorities if contamination has occurred.
Cleanup Methods: Absorb spillage with inert material (sand, earth). Collect in suitable, labeled chemical waste containers. Ventilate area. Decontaminate surfaces with sodium thiosulfate solution.
Specific Spill Response: Recommended use of mercury spill kit and appropriate PPE.
Safe Handling Advice: Avoid generation of dust or aerosols. Wear proper PPE at all times. Only handle in well-ventilated areas inside chemical fume hoods.
Storage Requirements: Store in tightly closed container, in dry place at room temperature. Keep away from incompatible substances like acids, strong oxidizers, ammonia, and sulfide compounds.
Special Practices: Keep away from food, drink, and animal feed. Wash hands thoroughly before breaks and after handling.
Packing Materials: Use corrosion-resistant and shatterproof containers.
