Inhalation: Move the affected person to fresh air; Allow rest in a position comfortable for breathing; Seek attention if symptoms persist
Ingestion: Rinse mouth with water; Never induce vomiting; Obtain medical attention promptly
Medical Attention: Health professionals should monitor for chemical exposure symptoms and ensure sufficient respiratory and cardiac support if complications arise
Main Symptoms/Effects: Eye pain, skin burning, gastrointestinal upset
Extinguishing Media: Use dry chemical powder, carbon dioxide (CO2), foam, or water spray for small fires
Specific Hazards: Combustion may release hazardous vapors such as nitrogen oxides, carbon oxides, sulfur oxides, and hydrogen fluoride
Protective Equipment: Firefighters need full protective equipment and self-contained breathing apparatus
Firefighting Advice: Move containers from fire area if it can be done safely; Cool intact containers with water spray; Avoid inhaling vapors or combustion products
Personal Protection: Wear gloves, goggles, and chemical-resistant clothing; Use appropriate respiratory protection if dust or fumes become airborne
Spill Handling: Avoid generating dust; Ventilate the area; Collect spill in suitable, closed containers for proper disposal using non-sparking tools
Cleanup Methods: Sweep up without raising dust, place in disposal container; Wash area thoroughly with water and mild detergent
Environmental Precautions: Prevent run-off to drains, surface water, and soil; Report significant releases to appropriate authorities
Disposal Method: Dispose of solid waste according to local, state, and federal guidelines; Label all disposal containers clearly
Decontamination: Wash spill site with large amounts of water after material pick-up is complete
Handling: Avoid inhalation, ingestion, and skin or eye contact; Handle under dry, ventilated conditions; Use only equipment designed for chemical handling
Hygiene Measures: Wash hands, face, and exposed skin before breaks and after work
Storage: Store tightly closed in original container; Keep in a cool, dry, ventilated space; Keep away from incompatible substances such as strong oxidizers and acids
Shelf Life: Stable over several years if kept dry and sealed from atmospheric moisture
Special Precautions: Containers must remain tightly sealed to prevent moisture absorption; Label and date all containers clearly from receipt onwards
Occupational Exposure Limits: No established exposure limits – minimize personal exposure as a best practice
Engineering Controls: Use fume hoods, local exhaust ventilation; Implement dust control measures if powder handling
Personal Protection: Wear chemical-resistant gloves (nitrile or neoprene), safety goggles, and lab coats; Use NIOSH-approved respirators during dust production or poorly ventilated conditions
Hygiene Practices: Wash hands thoroughly after handling; Do not eat, drink, or smoke in work areas; Remove and clean contaminated clothing before reuse
Appearance: White to off-white crystalline powder
Odor: Almost no odor
pH: Between 5 and 8 in aqueous solution
Melting Point: 150–160°C
Boiling Point: Decomposition before boiling
Flash Point: Not flammable
Solubility: Soluble in water and polar organic solvents (DMF, DMSO, acetonitrile)
Vapor Pressure: Negligible at room temperature
Density: Approximately 1.48 g/cm3
Other Properties: Hygroscopic, can clump if exposed to air; stable under normal conditions
Stability: Stable under recommended storage conditions; Avoid prolonged contact with air or moisture
Reactivity: Takes up water from the atmosphere; Reacts with strong acids, strong bases, and strong oxidizing agents
Hazardous Decomposition: On thermal decomposition, generates hazardous gases: nitrogen oxides, sulfur oxides, carbon oxides, hydrogen fluoride
Incompatible Materials: Strong oxidizers, strong acids, concentrated bases
Polymerization: No hazardous polymerization occurs
Acute Toxicity: Harmful if swallowed, inhaled, or in contact with skin, based on similar quaternary ammonium compounds
Skin Contact: Causes skin irritation; may lead to redness, pain, or dermatitis
Eye Contact: Causes eye irritation and damage, especially from dust or splashes
Inhalation: Inhalation results in coughing, throat irritation, and headache when dust occurs
Ingestion: May cause abdominal pain, gastrointestinal disturbances; higher doses risk systemic toxicity
Chronic Effects: Prolonged exposure may sensitize the skin or cause respiratory discomfort
Additional Information: No detailed carcinogenicity or reproductive toxicity studies published
Ecotoxicity: No thorough data, but quaternary ammonium compounds can impact aquatic organisms negatively
Persistence/Degradability: Compound resists rapid biodegradation; stays longer in soils and waters compared to simpler salts
Bioaccumulation Potential: Expected low due to hydrophilicity, although monitoring recommended for environmental discharge
Mobility in Soil: Readily soluble, risk of leaching to groundwater
Other Adverse Effects: Avoid introduction to natural waters, waste streams, or soil without careful assessment
Disposal Methods: Treat as hazardous waste; Utilize authorized waste disposal contractors
Waste Containers: Use tightly sealed, clearly labeled containers
Rinse Solutions: Collect rinsate and treat as chemical waste
Disposal of Packaging: Empty packaging handled as chemical waste after triple rinse; avoid reuse
