Note for Physician: Symptomatic and supportive care, monitor for iron toxicity symptoms such as nausea, abdominal pain, shock in severe cases
Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam, use water spray only to cool containers
Unsuitable Media: Avoid direct water stream on burning material
Hazardous Combustion Products: Nitrogen oxides, hydrogen chloride, iron oxides, carbon oxides
Firefighting Instructions: Self-contained breathing apparatus and full protective gear recommended, evacuate area around fire, control runoff

Protective Equipment: Wear chemical-resistant gloves, protective eyewear, face shield, suitable protective clothing
Personal Precautions: Avoid contact with spills, ventilate area, avoid inhaling vapors or dust
Cleanup Methods: Absorb with inert material such as sand or vermiculite, collect for disposal in labeled containers, wash area with water and detergent, prevent liquid from entering sewers or waterways
Environmental Precaution: Prevent uncontrolled discharge into environment, notify relevant environmental authorities as required
Handling: Utilize chemical fume hood or effective local exhaust, avoid generating mists, do not eat or drink in area of use, avoid prolonged or repeated contact, use only with appropriate PPE
Storage: Store in tightly closed containers, keep in cool, dry, and well-ventilated area, keep away from strong bases, oxidizers, and moisture, maintain containers upright and clearly labeled, keep separate from food and feedstuffs
Engineering Controls: Work in a well-ventilated space or under chemical hood, install eyewash stations and safety showers nearby
Occupational Exposure Limits: No established limit for the compound, occupational exposure standards for iron dust & chloride ions: consult ACGIH for TLVs, recommend keeping airborne concentrations below 1 mg/m³ for iron
Respiratory Protection: Use approved respirator if exposure is possible, especially during spills or prolonged handling
Skin Protection: Nitrile or PVC gloves, lab coat with long sleeves
Eye/Face Protection: Chemical safety goggles and face shield
Hygiene Measures: Wash exposed skin after handling, change contaminated clothing immediately
Appearance: Pale yellow to light brown solid or viscous liquid
Odor: Faint amine or metal-like
pH: Acidic, pH 2-4 (for 10% aqueous solution)
Melting Point: 60–80°C (varies with composition)
Boiling Point: >200°C (decomposes before boiling)
Solubility: Highly soluble in water, soluble in polar organic solvents
Density: 1.15–1.35 g/cm³ at 20°C
Viscosity: Moderate to high viscosity at room temperature
Flash Point: >140°C
Decomposition Temperature: >170°C, with release of fumes
Vapor Pressure: Negligible at 20°C

Acute Toxicity: LD50 (oral, rat): estimated 400–1000 mg/kg, may vary by composition
Skin Irritation: Causes moderate irritation with prolonged exposure
Eye Effects: Can cause painful inflammation and possibly corneal injury if not rinsed promptly
Sensitization: No known sensitization reported for ionic liquid forms
Chronic Effects: Prolonged, repeated exposure may impact liver or kidneys due to chloride and iron, few long-term studies available

Mutagenicity/Teratogenicity: Not adequately tested for these endpoints; use caution
Aquatic Toxicity: Harmful to aquatic organisms, possible risk of long-term adverse effects in aquatic environment
Persistence and Degradability: Likely not readily biodegradable, ionic liquids may persist in soils and sediments
Bioaccumulation: Expected to have low bioaccumulation potential for iron, chloride ions dissipate, imidazolium moiety may not accumulate
Mobility in Soil: High mobility due to water solubility, potential leaching risk
