Suitable Extinguishing Media: Water spray, dry chemical powder, carbon dioxide, foam
Unsuitable Extinguishing Media: Do not use water jet directly onto burning product
Special Exposure Hazards: Combustion may produce toxic fumes such as hydrogen bromide, nitrogen oxides, and carbon monoxide
Protective Equipment: Firefighters should wear self-contained breathing apparatus and chemical protective clothing
Special Procedures: Use water spray to cool unopened containers that are exposed to fire, move containers from fire area if safe to do so
Personal Precautions: Use proper personal protective equipment, such as gloves, goggles, and lab coat, avoid dust formation and inhalation
Environmental Precautions: Prevent product from entering drains, soil, or waterways, contain spill using absorbent material
Spill Clean-up Methods: Sweep up or collect spilled material, place in a suitable container for disposal, ventilate area, wash spill site after containment
Handling Spills: Avoid breathing dust, ensure adequate ventilation in the area, dispose of waste in accordance with local regulations, report large spills as required
Handling: Avoid contact with skin and eyes, minimize dust generation, use only in well-ventilated areas, keep containers tightly sealed when not in use, handle away from incompatible materials such as strong oxidizers
Storage: Store in a cool, dry, well-ventilated space, protect from moisture and direct sunlight, keep container tightly closed, segregate from strong acids or oxidizing agents
Storage Temperature: Ambient temperature recommended, avoid extreme heat or freezing
Engineering Controls: Work in a chemical fume hood or use local exhaust ventilation to avoid exposure to dust or vapors
Personal Protection: Chemical-resistant gloves, safety goggles, laboratory coat, and closed footwear required during handling
Respiratory Protection: If inhalation risk exists, use NIOSH/MSHA-approved respirator or equivalent
Hygiene Measures: Wash hands thoroughly after handling, avoid eating or drinking near work area, remove contaminated clothing
Exposure Limits: No OSHA/ACGIH exposure limits established for this specific compound, follow general good laboratory practices
Appearance: White or off-white powder or crystalline solid
Odor: Mild, may be slightly characteristic, noted as faint aromatic under some conditions
pH: Not available for pure solid, may show near-neutral range in aqueous solution
Melting Point: 110–120°C (varies with purity)
Boiling Point: Decomposes before boiling, not useful as a liquid at elevated temperatures
Solubility: Soluble in water, ethanol, other polar organic solvents
Density: Usually in the range of 1.2–1.3 g/cm³
Vapor Pressure: Negligible at room temperature
Flash Point: Not easily flammable, exact value unavailable
Partition Coefficient: Not established, but generally low octanol-water partition coefficient expected for ionic liquids
Stability in Storage: Stable at normal temperatures and pressures, keep closed to avoid moisture uptake
Chemical Stability: Stable under recommended conditions, avoid prolonged exposure to light or moisture
Hazardous Reactivity: Exposure to strong oxidizers, acids, or bases may lead to hazardous decomposition
Decomposition Products: Decomposition at high temperature can release toxic gases (hydrogen bromide, nitrogen oxides, carbon compounds)
Potential Incompatibilities: Strong oxidizing agents, reducing agents, acids, bases
Polymerization: No evidence suggests risk of hazardous polymerization
Potential Effects – Inhalation: Can cause respiratory tract irritation, coughing, headache if inhaled
Potential Effects – Skin Contact: May cause redness, dryness, or moderate irritation upon prolonged contact
Potential Effects – Eye Contact: Causes significant eye irritation, discomfort, possible temporary damage (if not washed promptly)
Potential Effects – Ingestion: Harmful if swallowed, may result in nausea, vomiting, or gastrointestinal irritation
Chronic Exposure: No long-term exposure data available; repeated exposure likely increases irritation risk
Carcinogenicity: Not listed by IARC, NTP, or OSHA as a known carcinogen
Mutagenicity/Teratogenicity: Not tested comprehensively; insufficient data for full assessment
Ecotoxicity: Potential to be toxic to aquatic life at high concentrations, no complete ecotoxicity study available
Biodegradability: Persistence in environment possible; ionic liquids often show limited biodegradability
Mobility in Soil: May migrate through soil depending on solubility and local conditions
Bioaccumulation: Expected to have low bioaccumulation based on molecular size and charge
Aquatic Impact: Should avoid discharge to surface water, sewer, or groundwater systems due to uncertain ecological effects
