Protective Equipment: Full protective gear and self-contained breathing apparatus recommended for large fires
Advice for Firefighters: Use standard firefighting procedures, keep unaffected containers cool with water spray, avoid inhalation of combustion byproducts

Accidental Release Measures

Personal Precautions: Evacuate unnecessary personnel, provide adequate ventilation, wear suitable protective clothing and gloves
Environmental Precautions: Prevent release to soil, surface water, drains; contain spill using inert absorbent such as vermiculite
Clean-Up Methods: Collect spilled material in suitable closed containers for disposal, wash area with water after removal
Disposal of Clean-Up Materials: Dispose of contaminated absorbents in accordance with local regulations
Additional Advice: Ensure area is well ventilated before reoccupation

Handling and Storage

Protective Measures: Use in well-ventilated area, avoid contact with skin and eyes, wash thoroughly after handling
Safe Handling Advice: Use only as intended, keep away from incompatible materials (strong oxidizers, acids)
Storage Conditions: Store in tightly sealed original container, cool and dry, protect from light and moisture, temperature ideally between 2-8°C
Incompatible Materials: Strong acids, strong oxidizing agents
Special Requirements: Ensure proper labeling and secondary containment for bulk containers, keep away from foodstuffs

Exposure Controls and Personal Protection

Ecological Information

Toxicity to Aquatic Life: Limited studies; ionic liquids like [C10mim][OAc] may produce moderate toxicity to aquatic organisms at elevated concentrations
Persistence and Degradability: Not rapidly biodegradable, may persist in the environment
Bioaccumulative Potential: Low to moderate; more data needed
Mobility in Soil: High solubility in water increases mobility, risk of leaching to groundwater
Other Adverse Effects: Do not allow large amounts to reach surface water or sewage systems to limit impact on microbial activity

Disposal Considerations

Waste Disposal Methods: Collect and place in appropriate designated waste container, do not pour into drains or sewers
Contaminated Packaging: Triple rinse containers, offer for chemical recycling where possible
