Fire Fighting Procedures: Remove containers from fire area if safe, cool with water spray, prevent runoff from entering drains
Special Notes: Situations involving larger quantities should be reported to emergency responders with specialized chemical incident training
Personal Precautions: Evacuate unprotected personnel, ventilate area, avoid contact with eyes and skin, use PPE including gloves and goggles
Environmental Precautions: Prevent release into soil, drains, or waterways, barricade spill area
Spill Response: Contain with inert absorbent like sand or vermiculite, scoop up for designated waste disposal, wash spill site with soapy water
Cleaning and Disposal: Double-bag waste for transport in compliance with hazardous waste regulations
Notification Requirements: Inform authorities in case of significant leakage, follow local spill reporting protocols
Safe Handling: Wear chemical-resistant gloves, splash-resistant goggles, avoid breathing mist or vapors, use mechanical ventilation or fume extraction

Incompatibilities: Strong acids, strong bases, oxidizing agents
Specific Requirements: Label storage area clearly, keep containers sealed and upright to prevent leaks
Hygienic Practices: Wash hands after handling, avoid eating or drinking near storage or use sites
Occupational Exposure Limits: No established OELs to date, follow general solvent exposure guidelines
Ventilation: Employ local exhaust or general ventilation to reduce vapor levels
Personal Protective Equipment: Gloves (nitrile or neoprene), chemical splash goggles, lab coat or chemical apron
Respiratory Protection: Use NIOSH-approved respirator for tasks where airborne concentrations could rise, especially during spills or large-scale transfer
Environmental Controls: Procedure layouts should enable prompt identification and management of leaks

Incompatible Materials: Strong oxidizing/reducing agents, alkali metals, moisture over prolonged periods
Potential Routes of Exposure: Inhalation, skin absorption, eye contact, ingestion
Acute Effects: Causes local skin and eye irritation, may upset stomach if ingested, inhalation of concentrated vapors causes discomfort
Data Sources: Limited detailed animal testing, similar ionic liquids suggest low direct systemic toxicity, not classified as a carcinogen
Chronic Effects: No long-term studies on human health available, recommended to limit unnecessary exposure pending further research
Symptoms of Overexposure: Skin redness, itching, irritation of eyes or throat, headache, upset stomach
Target Organs: Eyes, skin, possible respiratory system at high levels
Eco-Toxicity: Not fully assessed for aquatic species, related tetrafluoroborate salts show moderate persistence, may be toxic to aquatic life at high concentrations
Mobility: Some water solubility, can spread through soil and water bodies
Persistence and Degradability: Believed to be slow to biodegrade, caution recommended to avoid uncontrolled disposal
Bioaccumulation: No specific data, ionic liquids with similar structures tend not to bioaccumulate significantly
