Inhalation: Remove exposed person to fresh air, keep comfortable, get medical attention if symptoms persist or worsen; possible symptoms include coughing, headache, dizziness
Skin Contact: Wash exposed area with plenty of soap and water, remove contaminated clothing, seek medical attention if irritation continues
Eye Contact: Rinse cautiously with clean water for at least 15 minutes, keep eyelids open, remove contact lenses if present and easy to do, seek immediate medical care if discomfort persists
Ingestion: Rinse mouth, do not induce vomiting, give small amounts of water, medical attention required for symptoms such as nausea or breathing difficulties
Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, foam, use large volumes of water spray for significant fire in surrounding area
Unsuitable Extinguishing Media: High-pressure water jets may spread the chemical
Specific Hazards: Thermal decomposition generates toxic or corrosive gases such as hydrogen cyanide, nitrogen oxides, and carbon monoxide
Protective Equipment: Full firefighting gear, positive pressure self-contained breathing apparatus
Instructions: Keep containers cool by spraying with water, stay upwind, evacuate area if safe containment cannot be maintained
Personal Precautions: Evacuate unprotected persons, restrict area, use chemical-resistant gloves and goggles
Environmental Precautions: Keep spillage out of drains, ground water, and surface water, use barriers or absorbents for large spills
Cleanup Methods: Absorb with inert material such as vermiculite, transfer to labeled chemical waste containers, ventilate area thoroughly before re-entry
Disposal: Handle as hazardous waste, coordinate with certified chemical disposal contractor
Handling: Avoid inhaling vapors or dust; do not eat, drink, or smoke while handling; use fume hoods or well-ventilated spaces; inspect containers regularly for damage or leaks
Storage: Store in tightly closed containers, in cool, dry, well-ventilated locations remote from sources of heat, ignition or direct sunlight
Incompatible Materials: Strong acids, oxidizers, strong bases
Special Storage: Segregate from food and feed, clearly label and lock hazardous substances in dedicated stores
Exposure Limits: No OSHA or ACGIH exposure limits assigned; minimize exposure by technical and administrative controls
Engineering Controls: Local exhaust ventilation, chemical fume hoods, washable work surfaces
Personal Protective Equipment: Chemically resistant nitrile or neoprene gloves, splash-proof chemical goggles, laboratory coats or chemical resistant aprons, and closed footwear
Respiratory Protection: Use NIOSH-certified respirators in situations with dust, mists, or insufficient ventilation
Hygiene Measures: Wash hands thoroughly after handling, decontaminate protective gear between uses, do not reuse contaminated personal items without cleaning
Appearance: Clear or slightly yellow liquid at room temperature
Odor: Slight, characteristic
Odor Threshold: Not established
pH: Neutral to weakly basic in aqueous solution
Melting Point/Freezing Point: Melting point typically below room temperature
Initial Boiling Point/Range: Decomposes before boiling
Flash Point: >120°C (varies based on specific formulation)
Evaporation Rate: Not measurable under standard conditions
Flammability: Not readily flammable, but vapor and decomposition products are hazardous in fire situations
Vapor Pressure: Low at ambient conditions
Specific Gravity: 1.05–1.12 (20°C)
Solubility: Miscible with water
Partition Coefficient (n-octanol/water): Not readily available
Decomposition Temperature: Exceeds 180°C
Viscosity: Moderate for ionic liquids; check specific lot certificate for precise values
Chemical Stability: Stable in standard laboratory environments; avoid strong sunlight, open flames, or prolonged heat
Reactivity: Generally unreactive under normal handling and storage
Conditions to Avoid: High temperature, flames, strong oxidizers, extremely acidic or basic environments
Incompatible Materials: Oxidizing agents, strong mineral acids, alkali metals
Hazardous Decomposition Products: Combustion or thermal stress creates nitrogen oxides, hydrogen cyanide, and organic vapors
Routes of Exposure: Inhalation, skin and eye contact, accidental ingestion
Acute Toxicity: Oral and dermal LD50 values not fully established. Moderately toxic; exposure may provoke nausea, dizziness, burning sensation, or systemic effects
Skin Corrosion/Irritation: Prolonged or repeated exposure may cause moderate skin irritation
Serious Eye Damage/Irritation: Vapors and direct splashes may cause redness, tearing, and discomfort
Respiratory Sensitization: Not classified, but dust or vapor inhalation can trigger coughing and breathing difficulties
Carcinogenicity: No published long-term animal studies; not listed by IARC, NTP, or OSHA
Other Effects: Chronic effects on reproductive toxicity or organ damage remain unstudied; caution advised in continuous or uncontrolled use scenarios
Toxicity to Aquatic Life: Compound is harmful to aquatic organisms; laboratory studies show moderate acute and chronic toxicity for fish and invertebrates
Persistence and Degradability: Not rapidly biodegradable in standard environmental tests, persists in water and soil environments
Bioaccumulative Potential: Potential bioaccumulation in aquatic food chains remains uncertain; evidence points toward low but nonzero risk
Mobility in Soil: High water solubility suggests ready migration through soil into waterways
Additional Environmental Precautions: Never discharge un-neutralized or large-scale spills into sewers or open water. Waste management plans need to include spill containment and environmental monitoring
Disposal Methods: Classified as hazardous chemical waste; collect and store waste in labeled, sealed containers for licensed hazardous waste treatment
Contaminated Packaging: Treat empty containers or liners as hazardous unless properly rinsed and disposed through authorized waste handlers
Special Precautions: Never pour residues into drains, soils, waterways. Follow local and national regulations on hazardous material disposal; consult regulatory agencies or environmental authorities if in doubt
UN Number: Not classified under major hazardous goods codes because of low flammability, but shipping as regulated chemical advised
