5. Fire-Fighting Measures

Suitable Extinguishing Media: Dry chemical, CO2, foam, water spray. No direct water jet on burning chemical.
Fire Hazards: Emits toxic or corrosive fumes under combustion, especially hydrogen fluoride and phosphorus oxides
Protective Equipment: Self-contained breathing apparatus, full protective gear; avoid inhalation of gases produced in fires
Specific Hazards: Decomposition releases irritating, corrosive and toxic gases. Containers can burst at high temperature.
Firefighting Instructions: Keep unaffected containers cool, control runoff, prevent release to drains

6. Accidental Release Measures

Personal Precautions: Use gloves, goggles, and suitable face protection. Ventilate area. Avoid breathing vapor and contact with skin.
Environmental Precautions: Prevent material from entering drains or waterways. Notify regulatory authorities if spill pollutes environment.
Cleanup Methods: Small spills: absorb with inert material like vermiculite, sand, or earth. Transfer to chemical waste container. Clean contaminated surface with detergent and plenty of water.
Emergency Procedures: Restrict access. Use non-sparking tools. Dispose according to local, state, and federal regulations

7. Handling and Storage

Handling: Minimize direct contact. Prevent vapor buildup. Use with adequate ventilation or in fume hood. Avoid splashing.
Storage: Store tightly closed in a cool, dry, well-ventilated place away from acids, bases, moisture, and direct sunlight. Use corrosion-proof containers.
Keep Away From: Strong oxidizers, acids, bases, strong reducing agents, sources of ignition.
Other Precautions: Ensure containers remain labeled. Only trained personnel use product. Maintain good hygiene – no food or drink near chemicals.

8. Exposure Controls and Personal Protection

Engineering Controls: Laboratory fume hood or local exhaust ventilation. Use closed systems for larger uses.
Exposure Limits: Not established specifically for this ionic liquid, default to employer guidelines and best practice for unlisted compounds.
Personal Protection: Chemical-resistant gloves (nitrile, neoprene), goggles or full-face shield, lab coat, long sleeves. For significant airborne levels, respiratory protection (filter mask).
Environmental Exposure: Use spill containment if handling large amounts. Minimize release to environment.

10. Stability and Reactivity

Chemical Stability: Stable under normal storage and handling conditions, but hydrolyzes in presence of strong moisture
Reactivity: Reacts with strong acids, bases, and oxidizers
Hazardous Reactions: Decomposes at high temperature — produces HF, PF5, and other hazardous fluorine compounds
Incompatible Materials: Water, moisture, oxidizing agents, strong bases and acids
Decomposition Products: Fluorine-containing gases, phosphorus oxides, carbon oxides
Other Reactivity Notes: Prolonged exposure to light or heat increases decompositional risk

11. Toxicological Information
