Suitable Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide
Unsuitable Extinguishing Media: Avoid using full water jet
Specific Hazards: Combustion may produce toxic fumes including hydrogen fluoride, sulfur oxides, nitrogen oxides, and carbon oxides
Protective Equipment for Firefighters: Wear self-contained breathing apparatus, chemical-resistant clothing, and avoid inhaling fumes
Special Procedures: Cool containers with flooding quantities of water until well after fire is out, avoid discharge of run-off water containing chemicals into drains or surface waters
Personal Precautions: Don eye protection, gloves, dust mask or respirator, use chemical-resistant boots and body covering as needed
Environmental Precautions: Do not allow spillage into drains, rivers, or soils, prevent further leakage or spillage if it can be done safely
Methods for Cleaning Up: Sweep up and shovel the material using non-sparking tools, place into a suitable closed chemical waste container, clean contaminated surface thoroughly with water and detergent, ventilate area
Handling: Use only in a chemical fume hood, avoid dust formation, avoid contact with eyes, skin, and clothing, wash hands after handling, do not eat, drink or smoke during use
Storage: Keep container tightly closed in a dry and well-ventilated area, store away from direct sunlight or sources of ignition, maintain storage at ambient conditions recommended (room temperature), separate from incompatible materials such as oxidizers and acids, clearly label containers
Engineering Controls: Ensure adequate ventilation, use fume extraction or local exhaust
Personal Protective Equipment: Wear safety goggles or face shield, chemical-resistant gloves (nitrile or neoprene), lab apron or coat, closed footwear
Respiratory Protection: Use NIOSH/MSHA approved dust respirator if dust generation is likely
Hygiene Measures: Wash hands, forearms, and face after handling chemical, keep work clothes separated from household laundry
Environmental Exposure Controls: Use containment to prevent environmental release

Ingestion: May lead to gastrointestinal discomfort, nausea, or vomiting, ingestion needs immediate attention
Chronic Effects: Not fully studied, avoid repeated or prolonged exposure until more data are available
Carcinogenicity, Mutagenicity, Reproductive Toxicity: Not classified due to lack of full studies, handle with caution based on general toxicity characteristics
Target Organs: Eyes, skin, upper respiratory tract
Aquatic Toxicity: Very toxic to aquatic organisms at elevated concentrations, risk of long-term adverse effects in the aquatic environment
Persistence and Degradability: Not readily biodegradable, ionic liquids such as these resist natural breakdown processes
Bioaccumulative Potential: May accumulate in aquatic environments, testing data are limited, potential risk exists
Mobility in Soil: Moderately mobile due to water solubility, contaminant migration risk in porous soils
Other Adverse Effects: Avoid discharge into drains, soil, or watercourses; any environmental release should follow remediation protocols
Waste Treatment Methods: Collect and contain for hazardous chemical disposal, follow all local, state, and national regulations for hazardous waste
Incineration: Treat by high-temperature incineration with regulatory emission controls
Do Not: Dump into drains, surface waters, public sewer systems, or open environments
