Skin Contact: Remove contaminated clothing, immediately rinse skin with plenty of water for at least 15 minutes, seek medical advice for persistent redness, irritation, or blistering.
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing, seek ophthalmological consultation for reddening, watering, or pain.
Ingestion: Rinse mouth, do not induce vomiting, get medical help if feeling unwell or after large ingestion, provide the product label or SDS to healthcare professional.
Notes for Physician: Treat symptomatically, no known specific antidote
Suitable Extinguishing Media: Use dry chemical, CO₂, foam, or water spray – use water jet only for cooling closed containers.
Hazards from Combustion: Can produce carbon oxides, nitrogen oxides, hydrogen bromide, imidazole derivatives.
Protective Actions: Wear self-contained breathing apparatus and full protective gear, avoid inhaling combustion products.
Specific Hazards: Thermal decomposition releases toxic and irritant fumes
Special Procedures: Keep containers cool with water spray if exposed to heat or fire, prevent runoff from entering drains
Personal Precautions: Use suitable personal protective equipment (PPE) such as gloves, goggles, lab coat, avoid breathing dust or vapor.
Environmental Precautions: Prevent spills from entering soil, waterways, or sewage system, notify authorities if contamination occurs.
Spill Cleanup Methods: Collect spills using inert absorbent material (sand, earth, vermiculite), transfer to labeled waste container, clean area with water and detergent.
Disposal: Dispose of material following national regulations and hazardous waste guidelines
Handling: Avoid skin and eye contact, minimize dust and vapor generation, handle in fume hood or well-ventilated area, use PPE including gloves and splash-proof goggles.
Hygiene Measures: Wash hands and face before eating or drinking, do not eat, drink, or smoke near work area, change contaminated clothing.
Storage Conditions: Store in tightly closed original container, keep in cool, dry, and well-ventilated area, protect from moisture and direct sunlight.
Incompatibilities: Strong oxidizing agents, acids, sources of ignition
Control Parameters: No established occupational exposure limits, minimize exposure through engineered controls.
Engineering Controls: Ensure adequate ventilation, use fume hood in laboratory, install eyewash stations and safety showers.
Personal Protection: Wear protective gloves (nitrile or equivalent), chemical splash goggles, laboratory coat or other suitable protective clothing, approved dust mask or respirator for powder handling.
Environmental Protection: Prevent release into environment, implement spill containment practices

Routes of Exposure: Inhalation, ingestion, skin and eye contact.
Acute Effects: Harmful if swallowed or inhaled, causes skin and eye irritation.
Symptoms: Inhalation can trigger respiratory irritation, coughing, and throat discomfort; skin contact may produce redness or burning; eye exposure can result in redness, watering, or pain.
Chronic Exposure: No definitive chronic toxicity data available; repeated exposure may increase risk of sensitization or dermatitis.
LD50: Not specifically determined for this compound – related imidazolium salts show oral rat LD50 between 300–2000 mg/kg.
Carcinogenicity: No data available; not classified as carcinogenic.
