Firefighter Protection: Wear self-contained breathing apparatus (SCBA), chemical-resistant gloves, and full protective gear during fire
Firefighting Procedures: Use water spray to cool containers; prevent run-off from fire control from entering drains, waterways, or soil
Personal Precautions: Evacuate area for large spills; ventilate affected zone; prevent inhalation of dust or mist and direct contact with skin or eyes via gloves and goggles
Environmental Precautions: Prevent spillage from entering sewers or open bodies of water; inform authorities if large amounts enter water bodies
Methods for Containment: For solid or viscous fluid, use absorbent (vermiculite, sand, inert material), scoop up mechanically, place into labeled and tightly sealed chemical waste container
Cleaning Procedures: Wash contaminated surface thoroughly with water and mild detergent; dispose rinsate according to regulations
Secondary Measures: Confirm proper disposal and decontamination of response equipment and PPE
Safe Handling Guidelines: Handle under chemical fume hood or adequate exhaust; minimize exposure via splashing or aerosol generation; avoid prolonged skin contact; keep away from food and drink areas
Storage Conditions: Store in tightly closed original container in a dry, cool, ventilated area away from incompatible chemicals; avoid direct sunlight; maintain label visibility at all times
Incompatibilities: Strong oxidizers, strong bases, acids; avoid moisture contamination
Further Safety Notes: Do not smoke, eat, or drink while using; ensure eyewash station and emergency shower are accessible within workspace
Occupational Exposure Limits: No established threshold limit values, but minimize to the lowest practical exposure level
Engineering Controls: Fume hood or local exhaust recommended for all laboratory and process uses
Personal Protective Equipment (PPE): Chemical-resistant gloves (nitrile/rubber suggested); safety goggles with side shields; full-length lab coat or apron; respirator in absence of effective ventilation, particularly during processes that generate aerosol
Hygiene Measures: Wash hands, forearms, and face thoroughly after handling and before eating, drinking, or using restroom; launder contaminated clothing before reuse
Environmental Exposure Controls: Collect all spill residues and dispose according to rules for hazardous chemical waste

Likely Routes of Exposure: Inhalation of vapors, dermal contact, accidental ingestion, eye exposure
Acute Toxic Effects: Causes irritation to skin, eyes, mucous membranes; may be harmful if inhaled, swallowed, or absorbed
Chronic Toxic Effects: Long-term respiratory, dermal, or eye contact could lead to persistent irritation, potential allergic reactions; no evidence to suggest bioaccumulation under occupational conditions

Reproductive/Developmental Effects: Not enough data available for a definitive assessment, precaution advised
Exceptions: Persons with pre-existing chronic respiratory, eye, or skin conditions could be at higher risk of worsening symptoms from exposure
Other Hazards: Vapor or mist could cause coughing, shortness of breath, or sore throat if inhaled in high quantities
Ecotoxicity: Absence of direct aquatic toxicity data; structurally similar ionic liquids show moderate to high toxicity to aquatic invertebrates and algae at low concentrations
Persistence/Degradability: Expected to degrade slowly; ionic nature resists quick breakdown by natural processes
Bioaccumulative Potential: Salts and ionic liquids generally exhibit low bioaccumulation but are highly mobile in wet environments
Mobility in Soil: Substance may move readily through soils and sediments; runoff control suggested
Other Effects: Monitor and restrict uncontrolled release to prevent unintended changes in water chemistry and biota
