First Aid Measures

Inhalation: Move affected person to fresh air, monitor for shortness of breath, consult medical attention if irritation persists
Skin Contact: Remove contaminated clothing, wash skin with soap and water
Eye Contact: Rinse eyes thoroughly with water for at least 15 minutes, lift eyelids frequently, obtain medical care if irritation continues
Ingestion: Rinse mouth with water, drink water to dilute, seek medical help for large amounts or if feeling unwell
Special Medical Notes: Treat symptomatically, no specific antidote

Fire-Fighting Measures

Suitable Extinguishing Media: Use water spray, carbon dioxide, dry chemical, or foam
Unsuitable Media: Avoid high volume water jets
Hazardous Combustion Products: Carbon oxides, calcium oxide, possibly irritating fumes
Protective Equipment For Firefighters: Wear self-contained breathing apparatus, full protective equipment
Flash Point: Not flammable under regular handling
Special Precautions: Evacuate area if involved in a large fire, prevent runoff into waterways

Accidental Release Measures

Personal Precautions: Wear protective clothing, avoid dust formation, ensure proper ventilation
Environmental Precautions: Prevent powder from entering drains, waterways, or soil
Methods For Cleaning Up: Sweep up without generating dust, use dust suppressant if sweeping large amounts, place in approved containers for disposal
Emergency Procedures: Wash spill area with plenty of water after material removal, ventilate area if inside

Handling and Storage

Handling: Use in areas with good ventilation, avoid generating dust, prevent contact with skin and eyes
Storage: Store in tightly closed containers, keep dry and cool, protect from moisture, segregate from strong acids
Special Notes: Keep containers labeled and closed when not in use, restrict access to trained personnel

Exposure Controls and Personal Protection

Engineering Controls: Use local exhaust ventilation, general room ventilation works well for small quantities
Personal Protective Equipment: Chemical safety goggles, gloves resistant to chemicals, lab coat or long sleeves, dust mask if dust concentrations warrant
Hygiene Measures: Wash hands after handling, do not eat or drink near the substance
Exposure Limits: No individual occupational limits assigned for calcium acetate
Environmental Controls: Use containment methods to prevent environmental release

Bioaccumulative Potential: Expected to have low bioaccumulation
Mobility in Soil: High mobility as a water-soluble substance
Other Ecological Effects: Eutrophication possible if released in massive amounts, disrupting surface water balance

Disposal Considerations

Waste Treatment Methods: Dispose of in accordance with local, regional, and national regulations
Disposal of Product: Small amounts may go to landfill with non-hazardous solids, large quantities require approved chemical disposal
Container Disposal: Triple rinse and dispose as non-hazardous waste unless contaminated
Special Precautions: Do not release into waterways, avoid generating airborne dust during disposal operations
