Suitable Extinguishing Media: Water mist, foam, dry chemical powder, carbon dioxide
Unsuitable Extinguishing Media: Direct water streams that may spread material
Specific Hazards: During combustion, may emit toxic gases such as hydrogen chloride, nitrogen oxides, and carbon oxides
Protective Equipment: Wear self-contained breathing apparatus and full protective gear when fighting chemical fires
Advice for Firefighters: Prevent runoff from fire control; contaminated water may pose environmental hazard
Fire/Explosion Risk: Product is not flammable but decomposition during fire can cause hazardous gas release
Personal Precautions: Evacuate unnecessary personnel, avoid breathing vapor, dust, or spray, use goggles and suitable gloves
Environmental Precautions: Prevent further leakage or spillage if safe to do so, avoid discharge to drains or water courses
Method for Cleanup: Collect spillage mechanically, absorb with inert material (vermiculite, sand), place in closed container for disposal
Decontamination: Ventilate the area, wash spill site after material pickup is complete
Disposal: Dispose of contaminated material as chemical waste according to local regulations
Handling: Avoid contact with skin, eyes, and clothing. Minimize exposure by working inside chemical fume hoods or with proper local exhaust. Do not eat, drink, or smoke during use. Wash hands thoroughly after handling.
Storage Conditions: Store locked up in a tightly closed container, in a cool, dry, well-ventilated space, away from incompatible substances like strong oxidizers and acids. Keep container clearly labeled and out of direct sunlight.
Storage Incompatibilities: Do not store near food or drink. Steer clear of moisture, oxidizing agents, and strong bases.
Exposure Limits: No established occupational exposure limits; handle as potentially hazardous
Engineering Controls: Use in chemical fume hood or with local exhaust ventilation
Respiratory Protection: NIOSH-approved respirator for dusts or vapors if exposure levels may be exceeded or ventilation is inadequate
Hand Protection: Chemically resistant gloves (such as nitrile rubber)
Eye Protection: Chemical safety goggles or face shield
Skin Protection: Lab coat, chemical apron, protective boots as needed
Hygiene Measures: Wash hands and face before breaks and immediately after handling substance
Appearance: White to off-white crystalline powder
Odor: Characteristic, slightly sweet or ester-like
Melting Point: 80°C - 120°C depending on purity and batch
Boiling Point: Not applicable (decomposes before boiling)
Flash Point: Not flammable under standardized test conditions
Solubility: Freely soluble in water and polar organic solvents like methanol, ethanol, and DMSO
pH: Slightly acidic in aqueous solution
Vapor Pressure: Negligible at room temperature
Density: 1.25 – 1.35 g/cm³ (varies slightly by batch)
Other Data: Hygroscopic; absorbs moisture from atmosphere
Chemical Stability: Stable at room temperature under recommended storage and handling practices
Reactivity: Incompatible with strong oxidizers, strong acids, and bases
Hazardous Decomposition Products: Releases toxic gases including hydrogen chloride, nitrogen oxides, carbon oxides upon heating or combustion
Polymerization: Not expected under normal conditions
Other Conditions to Avoid: Prolonged exposure to moisture or elevated temperature can degrade product quality
Likely Routes of Exposure: Skin and eye contact, ingestion, inhalation of dust or vapor
Acute Toxicity: May cause moderate irritation to mucous membranes, skin, and eyes; oral and dermal LD50 data in rodents indicate moderate toxicity
Symptoms: Irritation of eyes, skin, respiratory tract; headache, dizziness, abdominal discomfort possible with significant exposure
Chronic Effects: No long-term studies available; potential target organ effects not well-defined
Carcinogenicity: No data indicating carcinogenic activity
Other Effects: Not conclusively mutagenic or teratogenic following current knowledge
Ecotoxicity: Harmful to aquatic life based on structurally related ionic liquids; avoid release to the environment
Persistence and Degradability: Product likely persists in the environment, not readily biodegradable
Bioaccumulative Potential: Not expected to bioaccumulate significantly
Mobility in Soil: Mobile in water; may contaminate groundwater if released
Other Adverse Effects: Toxicity data are limited, treat spills as hazardous to water sources and wastewater treatment plants
Waste Disposal: Must treat as hazardous waste. Dispose in accordance with local, regional, and national regulations.
Container Disposal: Triple-rinse containers, then puncture and recycle or dispose of in accordance with chemical waste procedures
Other Disposal Recommendations: Do not allow material to enter natural water sources, public sewage systems, or environment. Use registered disposal contractors for chemical waste.
