General Advice: Seek immediate medical attention for any persistent symptoms after exposure.
Inhalation: Move person to fresh air. If breathing is difficult, supply oxygen and seek medical help. Remove any source of exposure.
Skin Contact: Remove contaminated clothing. Rinse skin with water for at least 15 minutes. Seek medical aid for persistent irritation.
Eye Contact: Flush eyes with water for at least 15 minutes, lifting eyelids occasionally. Remove contact lenses if present. Get medical attention if irritation continues.
Ingestion: Rinse mouth with water. Do not induce vomiting unless directed by medical personnel. Monitor for symptoms and contact poison control or physician immediately.
Suitable Extinguishing Media: Use dry chemical, foam, carbon dioxide or water spray. Choose extinction method suitable for surrounding materials.
Special Hazards: Releases toxic and irritating fumes such as hydrogen bromide and nitrogen oxides under fire conditions. Combustion may produce carbon monoxide and carbon dioxide.
Protective Equipment: Wear self-contained breathing apparatus and full protective firefighting gear. Use water spray to cool containers away from fire. Avoid inhaling smoke or vapors.
Specific Hazards: Sealed containers may rupture if exposed to fire due to thermal expansion.
Personal Precautions: Evacuate area if necessary. Avoid dust formation. Wear suitable protective clothing, gloves, and safety goggles. Do not breathe vapors, dust, or mist.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Do not allow release into drains, watercourses, or soil. Notify authorities if significant spill occurs.
Cleanup Methods: Absorb with inert material such as sand, earth, or vermiculite. Gather up residue and place in tight, labeled containers for disposal. Clean surface thoroughly with water after material pickup. Ventilate spill area.
Handling: Work in a well-ventilated area, using local exhaust or fume hood if available. Avoid contact with skin, eyes, and clothing. Do not breathe dust. Wash hands after use. No eating, drinking, or smoking in work area.
Storage: Store in a tightly closed original container, away from incompatible substances such as strong oxidizers. Keep in cool, dry location away from direct sunlight and sources of ignition. Ensure proper labeling and prevent physical damage to containers. Secure storage area against unauthorized access.
Occupational Exposure Limits: No established exposure limits for this substance by OSHA, ACGIH, NIOSH, or EU.
Engineering Controls: Use laboratory fume hood or local exhaust ventilation. Ensure eyewash stations and emergency showers are accessible.
Personal Protective Equipment: Chemical splash goggles to prevent eye exposure. Lab coat or protective clothing. Nitrile or neoprene gloves for hand protection. Respiratory protection (N95 or higher) if airborne concentrations are present. Adequate footwear to avoid skin contact in case of spills.

Routes of Exposure: Skin contact, eye contact, inhalation, ingestion
Acute Toxicity: Harmful if swallowed (LD50 oral, rat: estimated >500 mg/kg). Causes eye and skin irritation in rabbits in standard testing.
Chronic Effects: Prolonged or repeated exposure may cause dermatitis or allergic reactions.
Symptoms: Redness, burning, itching of skin and eyes. Headache, dizziness, nausea from inhalation of dust or ingestion.
Carcinogenicity: Not listed as carcinogen by IARC, NTP, OSHA.
Reproductive Toxicity: No available data.

Additional Information: Handle with care. Prevent unnecessary exposure. Effects may worsen with higher concentrations or repeated contact.
Toxicity: Harmful to aquatic organisms. May cause long-term adverse effects in aquatic environments. Ecotoxicological data limited, suspected aquatic EC50: 1–10 mg/L.
Persistence and Degradability: Biodegradability not well studied. Likely persistence in the environment due to imidazolium structure.
Bioaccumulative Potential: Not measured, but long alkyl chain suggests moderate bioaccumulation.
Mobility in Soil: May have moderate mobility due to partial water solubility.
Other Adverse Effects: Avoid release to water or soil. Environmental impact increases at higher concentration.
Waste Disposal: Dispose of according to local, regional, and national regulations. Treat as hazardous chemical waste. Consult with licensed waste disposal service.
Container Disposal: Empty containers must be triple-rinsed, then destroyed or disposed by licensed contractor. Do not reuse for other substances.
