Self-Protection of First Aiders: Use PPE (gloves, goggles, mask), avoid direct contact, stay upwind if powder or vapor present
Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam, or sand; avoid using water on powder form
Unsuitable Extinguishing Media: High-pressure water jets (may spread powder or generate hazardous vapors)
Specific Hazards: Toxic and corrosive gases (hydrogen fluoride, nitrogen oxides, sulfur oxides) can form on heating or exposure to water
Firefighters’ PPE: Self-contained breathing apparatus, chemical-resistant full-body suit
Advice for Firefighters: Evacuate area; cool adjacent containers with water spray; avoid inhaling combustion or decomposition fumes
Explosion Risk: Product is not explosive, but dust dispersed in air may ignite under certain conditions; containers may rupture if exposed to extreme heat
Personal Precautions: Isolate spill site; ventilate area; restrict unprotected entry; wear appropriate protective equipment—including respiratory protection, chemical goggles, impervious gloves and suit
Environmental Precautions: Prevent spill entering drains or watercourses; material is hazardous to aquatic systems
Containment: Dike spill with inert absorbent (sand, vermiculite, earth); minimize dust formation
Cleanup: Collect dry material with equipment that does not generate dust; transfer to secure, labeled containers for disposal; wash area with copious water
Decontamination: Neutralize residues with dilute basic solution; ventilate area thoroughly
Disposal: Dispose of materials in accordance with national, regional, local environmental regulations
Handling: Use only in well-ventilated areas; avoid contact with skin, eyes, and clothing; minimize dust generation; do not eat, drink, or smoke in work area; use proper grounding and bonding to prevent static discharge
Storage: Store in tightly closed original container, in cool, dry, well-ventilated location; protect from direct sunlight, humidity, moisture, and incompatible materials (acids, bases, oxidizers, water); keep away from food and feedstuffs
Incompatible Materials: Strong acids, bases, reducing agents, water, oxidizing materials
Recommended Packaging: Corrosion-proof, moisture-proof containers with inert gas blanketing
Special Precautions: Regularly inspect storage area for leaks or container integrity
Occupational Exposure Limits: No established OELs specifically for LiFSI; handle as hazardous chemical
Engineering Controls: Use local exhaust or general ventilation to maintain airborne concentrations below hazardous levels; use glovebox or fume hood for powder handling
Personal Protective Equipment: Approved respirator for dust or vapor; chemical-resistant gloves (nitrile, neoprene), long-sleeved laboratory coat or chemical suit, goggles or full face shield, anti-static footwear
Hygiene Measures: Wash hands, forearms, face after handling; remove contaminated clothing promptly; do not reuse contaminated PPE without decontamination
Environmental Controls: Prevent release to water, soil, air; use containment and closed systems for bulk handling
