Eye Contact: Rinse cautiously with water for several minutes; remove contact lenses if present and easy to do; seek medical attention for irritation
Ingestion: Rinse mouth thoroughly with water; no special measures needed for small quantities, but seek guidance if large quantities are involved or symptoms occur
Special Note: Provide medical responders with product’s identification and nature of exposure
Suitable Extinguishing Media: Water, carbon dioxide, dry chemical, or appropriate foam
Unsuitable Extinguishing Media: No specific incompatibilities are documented
Special Hazards: Organic dust may form combustible mixtures with air; thermal decomposition can produce carbon monoxide and carbon dioxide
Protective Equipment: Self-contained breathing apparatus and full protective gear
Fire-Fighting Instructions: Avoid generating dust clouds; contain runoff with fire-fighting water
Personal Precautions: Avoid creating dusty conditions; use personal protective equipment like a dust mask and goggles
Environmental Precautions: Prevent entry into drains or waterways; sweep up carefully to minimize dust emission
Cleanup Methods: Collect mechanically; transfer to containers for disposal; wash area with water after removal
Disposal: Dispose of collected material according to local, regional, or national regulations
Handling: Use with adequate ventilation; minimize dust generation and accumulation by maintaining clean work environments
Personal Protection: Wear standard workplace gloves, goggles, and a dust mask or respirator in dusty areas
Storage Conditions: Store in a cool, dry, and well-ventilated area; keep container tightly closed and away from moisture
Incompatibilities: Strong acids and strong oxidizing agents can cause decomposition
Occupational Exposure Limits: No specific OSHA, ACGIH, or EU exposure limits for calcium alginate; use general dust limits (e.g., nuisance dust: 10 mg/m³ total, 3 mg/m³ respirable)
Engineering Controls: Local exhaust ventilation, dust extraction where dust formation is possible
