Suitable Extinguishing Media: Foam, dry chemical powder, carbon dioxide, water spray
Unsuitable Extinguishing Media: Straight water streams
Specific Hazards: Thermal decomposition may release imidazole, nitrogen oxides, sulfur oxides, hydrogen cyanide
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear
Fire-Fighting Advice: Move containers from fire area if safe; cool exposed tanks with water spray
Personal Precautions: Use gloves, safety goggles, lab coat; absorb vapors with adequate ventilation
Emergency Procedures: Evacuate unnecessary personnel; prevent further leakage or spillage
Environmental Precautions: Avoid discharge into drains, waterways, or soil
Cleanup Methods: Absorb spilled material with inert substance (sand, earth); collect in labeled containers for disposal; thoroughly ventilate area
Handling: Use local exhaust ventilation; avoid skin and eye contact; keep away from incompatible substances like strong oxidizers
Storage Conditions: Store in well-ventilated, cool, dry place; keep container tightly closed; label clearly
Incompatibilities: Strong acids, strong bases, oxidizing agents
Storage Precautions: Protect from moisture, heat, direct sunlight; keep away from food and beverages
Exposure Limits: No occupational exposure limits established for this compound
Engineering Controls: Use fume hood or equivalent ventilation; ensure safety showers and eyewash accessible
Personal Protective Equipment: Nitrile gloves, chemical splash goggles, lab coat, closed shoes
Respiratory Protection: Use respirator with organic vapor cartridge if exposure risk occurs
Hygiene Measures: Wash hands before breaks, after handling; remove contaminated clothing promptly
Appearance: Colorless to pale yellow liquid or crystalline solid

Routes of Exposure: Skin and eye contact, inhalation, ingestion
Acute Toxicity: Not fully characterized; low to moderate oral and dermal toxicity seen in related ionic liquids
Skin Corrosion/Irritation: Causes irritation, possible dermatitis on prolonged exposure
Serious Eye Damage/Irritation: Causes irritation, tearing, redness
Sensitization: Rare; no evidence of sensitization during research or common laboratory usage
Chronic Effects: No long-term animal testing data available; substances of this class may cause mild organ toxicity over time
Carcinogenicity: Not listed as a carcinogen by IARC, NTP, OSHA
Other Effects: CNS depression possible in massive oral overdose scenarios
Aquatic Toxicity: Harmful for aquatic organisms, especially fish and invertebrates
Environmental Persistence: Ionic liquids may degrade slowly in natural waters
Bioaccumulation: Low bioaccumulation potential expected in aquatic organisms
Mobility: Highly soluble, may move readily in surface and ground waters
Other Adverse Effects: Prudent to avoid release into environment due to cumulative unknown risks from persistent pollutants
Waste Treatment Methods: Incinerate in a chemical incinerator equipped with afterburner and scrubber
Disposal of Contaminated Packaging: Dispose as unused product or according to local regulations
