Protection for Firefighters: Wear self-contained breathing apparatus and chemical protective clothing
Special Equipment: Chemical-resistant boots and gloves, full body suit
Additional Information: Move containers from fire area if safe; cool surroundings with fog or water spray; avoid run-off into sewers or water bodies
Personal Precautions: Keep unprotected individuals away; use personal protective equipment such as chemical-resistant gloves, safety goggles, and NIOSH-approved respirator
Environmental Precautions: Prevent entry into soil, drains, and surface water; contain spillage at source
Spill Response: Scoop or sweep spilled solid into appropriate chemical waste container; avoid dust formation; cover residue with inert absorbent (vermiculite or sand); ventilate area
Cleaning Methods: Wash spill site thoroughly with water after initial cleanup; collect all cleaning materials for proper disposal
Disposal Considerations: See detailed waste management guidelines below
Handling: Use gloves, goggles, and lab coat; avoid dust formation; do not eat, drink, or smoke while handling; ensure work practices minimize exposure
Work Practices: Use chemical fume hood for transfers; keep container tightly closed after use
Storage: Store in original tightly sealed containers, in a cool, dry, well-ventilated place; protect from direct sunlight, heat sources, and incompatible substances
Storage Temperature: Standard room temperature (15-25°C) unless specified otherwise by supplier
Incompatibilities: Strong oxidizing agents, strong bases, strong acids
Storage Class: General chemical storage, away from flammables and corrosives where possible
Control Parameters: No established occupational exposure limits; minimize airborne concentrations
Engineering Controls: Use local exhaust ventilation or chemical fume hood
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), safety goggles, lab coat, optional respirator (P95 or higher filter) for dusty operations
Hygiene Measures: Wash hands thoroughly after handling; remove contaminated clothing and wash before reuse
Environmental Controls: Prevent release or runoff to environment; use closed systems if feasible for larger quantities
Appearance: White to off-white crystalline powder
Odor: Odorless or faintly ammoniacal
Melting Point: 145-160°C (literature value, may vary by batch)
Boiling Point: Not easily measurable (decomposes)
Solubility: Readily soluble in water, ethanol, methanol, ethyl acetate
Vapor Pressure: Negligible at ambient temperature
Flash Point: >150°C (non-flammable by standard testing)
pH: Neutral (pH 6-8 in 1% aqueous solution)
Partition Coefficient (Log Kow): Not experimentally determined, presumed low due to ionic nature
Decomposition Temperature: Exceeds 200°C, releases toxic gases
Density: Approximately 1.3 - 1.4 g/cm³ (at 20°C)
Stability: Stable under recommended handling and storage conditions
Chemical Reactivity: May react vigorously with oxidizing agents, strong acids or bases
Decomposition Products: Thermal breakdown yields hydrogen fluoride, sulfur oxides, perfluoroalkyl compounds, nitrogen oxides
Polymerization: Not known to undergo hazardous polymerization
Conditions To Avoid: Avoid heating above decomposition point, exposure to open flame, or mixing with incompatible materials
Acute Toxicity: Not readily available for this specific salt, but similar pyridinium salts cause mild to moderate oral and dermal toxicity in animal studies
Oral Exposure: May cause abdominal discomfort, nausea, or vomiting if swallowed
Inhalation Exposure: Dust may irritate respiratory tract, causing coughing and breathing difficulties
Dermal Exposure: Repeated or prolonged contact can cause mild skin irritation
Eye Contact: Can produce rapid-onset conjunctival redness and watery discharge
Chronic Toxicity: Low chronic toxicity expected based on limited use, though evidence is insufficient; no evidence of mutagenicity or carcinogenicity in standard screens
Sensitization: No documented evidence, but caution suggested due to surfactant-like behavior
Medical Conditions Aggravated: Pre-existing skin, eye, or respiratory conditions may increase susceptibility to effects
Aquatic Toxicity: No conclusive data for this specific compound; similar quaternary pyridinium salts show moderate toxicity to aquatic organisms
Persistence and Degradability: Poorly biodegradable in the environment due to stable triflate anion; may persist in soil or groundwater
Bioaccumulation Potential: Unlikely owing to ionic nature; low bioaccumulation factor based on structure-activity relationships
Mobility in Soil: Likely to migrate in aquatic environments due to high solubility
Effects on Microorganisms: Can inhibit activity at elevated concentrations due to surfactant properties
Other Adverse Effects: No expected ozone depletion, global warming, or photochemical smog formation from structure
Precautions: Prevent uncontrolled release to natural waters and soils
Disposal Methods: Collect solid waste in tightly closed, properly labeled containers; dispose through licensed hazardous waste contractor
Incineration: Chemical incineration with afterburner and scrubber possible for small quantities; avoid direct disposal due to potential for toxic vapor formation
Waste Classification: Consult local, regional, or national regulations for chemical waste classification; typically treated as non-halogenated organic laboratory waste
Contaminated Packaging: Rinse triple-washed containers; dispose as hazardous chemical waste; do not reuse packaging
Special Notes: Never discharge into drains, surface water, or municipal waste streams
