Fire Hazards: Emits toxic fumes under fire conditions, including HF, SOx, NOx
Protective Equipment: Firefighters should use self-contained breathing apparatus and chemical protective clothing.
Advice: Remove containers from area of fire if safe; cool containers with water spray.
Personal Precautions: Evacuate unnecessary personnel; avoid dust generation; ventilate area
Protective Equipment: Chemical-resistant gloves, goggles, suitable mask or respirator
Environmental Precautions: Prevent spill from entering sewers, soil, waterways; contain leak with inert absorbent material
Cleanup: Sweep or scoop up material; collect in suitable, sealable containers for disposal; wash contaminated area with water
Safe Handling: Use only in well-ventilated areas; minimize dust formation; avoid inhalation and contact with skin and eyes; follow recommended hygiene practices
Storage Conditions: Keep in tightly closed container; store in cool, dry, well-ventilated area away from incompatible substances such as strong oxidizers and acids.
Storage Temperature: 2-8 °C for best stability
Incompatibilities: Avoid moisture, oxidizing agents
Exposure Limits: No specific occupational exposure limits.[General industry recommendations apply]
Engineering Controls: Use local exhaust ventilation; provide emergency eye wash and safety shower
Personal Protective Equipment: Gloves resistant to chemicals (nitrile or neoprene), safety goggles, lab coat, mask or respirator for high dust concentrations
Hygiene Measures: Wash hands thoroughly after use; avoid eating, drinking, or smoking during handling
Environmental Controls: Prevent direct release to the environment; use spill control materials

Odor: Odorless or faint smell
Melting Point: 75-90 °C
Boiling Point: Decomposes
Density: 1.47-1.53 g/cm³
Solubility: Soluble in water, organic solvents (acetonitrile, DMSO)
pH: Slightly acidic in aqueous solutions
Vapor Pressure: Negligible
Partition Coefficient: Not available
Viscosity: Not applicable (solid at room temperature)
Chemical Stability: Stable under recommended storage conditions
Reactivity: Stable under normal laboratory conditions
Hazardous Reactions: Reacts with strong oxidizers, strong acids; can release toxic gases upon thermal decomposition
Conditions To Avoid: High temperatures, moisture, incompatible materials
Decomposition Products: HF, SOx, NOx, trifluoromethanesulfonic acid vapors
Acute Toxicity: Data not fully established; expected to be low hazard by oral and dermal routes; inhalation of dust may irritate mucous membranes
Chronic Toxicity: Prolonged or repeated contact may cause skin and respiratory tract sensitivity
Effects Of Exposure: Skin redness, eye irritation, coughing, possible allergic reactions
Carcinogenicity: No components listed as carcinogen by NTP, IARC, or OSHA
Other Effects: Possible but unconfirmed adverse effects on kidney and liver after large exposures
Aquatic Toxicity: Toxic to aquatic organisms in case of large spills; may cause long-term adverse effects in aquatic environments
Persistence and Degradability: Limited biodegradability; stable fluorinated anions persist
Bioaccumulation: Potential is considered low; trifluoromethanesulfonyl imide anion may accumulate in the environment
Mobility In Soil: Water solubility enables potential spread in ground water
Other Information: Prevent direct discharge into natural waterbodies
