Suitable Extinguishing Media: Dry chemical powder, carbon dioxide, alcohol-resistant foam, or water spray
Specific Hazards Arising from the Chemical: Decomposes at high temperatures releasing hazardous gases such as carbon oxides, nitrogen oxides, hydrochloric acid vapors
Protective Equipment and Precautions: Firefighters should wear self-contained breathing apparatus, full protective clothing including gloves and face shield; approach from upwind to avoid hazardous vapors
Fire Fighting Instructions: Avoid using direct water streams; apply extinguishing media to the base of the flames
Personal Precautions: Evacuate area; use proper personal protective equipment including gloves, safety goggles, respirator if needed
Environmental Precautions: Prevent material from reaching drains or waterways by diking with inert material
Spill Response: Carefully collect solid spills using non-sparking tools into suitable containers for disposal; wash area with plenty of water and detergent; ventilate the area thoroughly
Handling: Use in well-ventilated areas or fume hoods; avoid breathing dust or vapors; wear gloves, safety glasses, and protective clothing; keep container tightly closed when not in use
Storage: Store in cool, dry, and well-ventilated conditions away from moisture or strong oxidizing agents; keep away from incompatible chemicals like strong bases or strong acids; use containers made of compatible material such as glass or certain plastics; label all containers properly
Engineering Controls: Utilize fume hoods, local exhaust ventilation, general room ventilation to minimize exposure; use sealed systems when possible
Personal Protective Equipment: Safety goggles or face shield, chemical-resistant gloves (nitrile, neoprene), lab coat or apron, closed-toed shoes; respiratory protection such as NIOSH-approved respirator for dust or vapors
Hygiene Measures: Wash thoroughly before breaks and at the end of handling; prevent contact with skin, eyes, and clothing; never eat, drink, or smoke in work areas
Appearance: White to off-white crystalline powder
Odor: Nearly odorless
Melting Point: Ranges around 70°C–80°C
Boiling Point: Decomposes before boiling
Flash Point: Not available; not expected to be flammable under normal conditions
Solubility: Readily soluble in water; also soluble in ethanol and some organic solvents
Vapor Pressure: Negligible at room temperature
Density: Approximately 1.25 g/cm³ (at room temperature)
pH (5% solution): Mildly acidic
Partition Coefficient: Not established
Evaporation Rate: Not volatile under standard conditions
Chemical Stability: Stable at normal temperatures and pressures in closed containers
Possibility of Hazardous Reactions: No dangerous polymerization expected; reacts with strong oxidizers or acids producing hazardous products
Conditions to Avoid: Exposure to moisture, excessive heat, open flames, and sources of ignition
Incompatible Materials: Strong acids, strong bases, oxidizing agents
Hazardous Decomposition Products: When heated, may release hydrogen chloride, carbon monoxide, carbon dioxide, and nitrogen oxides
Routes of Exposure: Skin contact, eye contact, inhalation, ingestion
Acute Toxicity: Not well-studied in humans; experimental data in animals suggest low acute oral and dermal toxicity
Skin Corrosion/Irritation: May cause moderate irritation with redness and discomfort
Serious Eye Damage/Irritation: Direct contact leads to irritation, redness, and temporary discomfort
Respiratory Sensitization: Dust inhalation could cause respiratory tract irritation, coughing, shortness of breath
Chronic Effects: No known significant long-term health effects with normal laboratory use; repeat exposure could aggravate pre-existing conditions
Carcinogenicity, Mutagenicity, Reproductive Toxicity: No data suggesting significant risks; not listed by IARC, NTP, or OSHA as carcinogenic
Medical Conditions Aggravated by Exposure: Pre-existing skin disorders, eye problems, asthma, or respiratory illnesses may show increased sensitivity
Ecotoxicity: Data limited, but potential exists for aquatic toxicity at high concentrations; avoids direct release to environment
Persistence and Degradability: Biodegradability not well studied; ionic liquids can persist in water and soil
Bioaccumulative Potential: Low to moderate, limited data on actual bioaccumulation
Mobility in Soil: Soluble in water, may migrate in the environment if spilled; prone to remain in surface or groundwater
Other Adverse Effects: Not classified as an ozone depleter or highly hazardous to atmospheric integrity; safe chemical management reduces environmental impact
Waste Disposal Methods: Collect in tight, labeled containers; use a licensed waste contractor for chemical disposal; do not release to sewers, soil, or watercourses
Contaminated Packaging: Rinse empty containers with water and dispose of as hazardous waste; comply with local, regional, and national regulations for chemical waste
UN Number: Not classified as dangerous for transport under current regulations
Transport Hazard Class: Not regulated
Packing Group: Not regulated
Labeling Requirements: Use appropriate chemical transport labels; protect containers from physical damage and moisture during transit
