5. Fire-Fighting Measures

Suitable Extinguishing Media: Carbon dioxide, dry chemical, foam, water spray
Unsuitable Extinguishing Media: None known relating to Bismuth Citrate
Specific Hazards: Material is not combustible; decomposition can release carbon oxides, bismuth oxides
Protective Equipment for Firefighters: Wear self-contained breathing apparatus, full protective gear
Advice for Firefighters: Move containers from area if possible; cool unopened containers with water spray to prevent build-up of pressure

6. Accidental Release Measures

Personal Precautions: Avoid breathing dust, wear protective gloves and masks; evacuate unprotected people from the area
Environmental Precautions: Prevent further leakage or spillage if safe; avoid discharge into drains, water sources
Spill Cleanup Methods: Sweep up and place in suitable, labelled containers for disposal; clean surface thoroughly to remove residual material
Additional Advice: Use non-sparking tools and ventilate the area; dispose of waste as per regulatory requirements

7. Handling and Storage

Safe Handling: Use in well-ventilated spaces; avoid contact with eyes, skin and clothing; avoid inhalation of dust; wash hands before eating or drinking
Safe Storage: Keep container tightly sealed in a cool, dry, well-ventilated area away from incompatible substances like oxidizing agents
Storage Temperature: Store at ambient temperature, away from direct sunlight
Incompatibilities: Strong oxidizers, acids
Container Requirements: Use corrosion-resistant, airtight containers; label appropriately

8. Exposure Controls and Personal Protection

Exposure Limits: No occupational exposure limit values specifically for Bismuth Citrate; use lowest practical exposure
Engineering Controls: Use local exhaust ventilation or process enclosures to minimize airborne dust
