Inhalation: Remove from exposure area to fresh air, monitor breathing, seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, rinse skin thoroughly with water and mild soap, seek medical attention for irritation or persistent rash
Eye Contact: Rinse eyes under running water for 15 minutes, avoid rubbing, ensure eyelids held open, get medical attention if irritation persists
Ingestion: Rinse mouth, do not induce vomiting, give water if person is conscious, seek medical advice promptly
Most Important Symptoms: Burning, redness, irritation of skin or eyes, abdominal discomfort if swallowed
Advice for Physicians: Treat symptomatically, consider effects related to imidazolium salt exposure, monitor for potential allergic response or respiratory distress
Suitable Extinguishing Media: Dry chemical powder, carbon dioxide, foam, avoid direct water stream if possible
Special Hazards: May release toxic fumes under fire conditions, including hydrogen chloride, nitrogen oxides, carbon oxides
Protective Equipment: Use self-contained breathing apparatus and full protective clothing
