Personal precautions: Isolate area, ventilate, avoid dust formation, wear dust mask and gloves
Environmental precautions: Prevent material entering drains, surface water, or soil
Clean-up actions: Sweep up, shovel into properly labeled containers for recycling or disposal, avoid dust dispersal
Decontamination: Wash affected surfaces with plenty of water, dispose wash water as hazardous waste
Notification: Inform responsible authorities in case of major spill or release
Handling: Handle with local exhaust ventilation, avoid inhaling dust, wear protective gloves and eye protection, avoid eating or drinking in work area
General hygiene: Wash hands and face thoroughly after processing, keep work clothing separate
Storage conditions: Store in original packaging, keep dry, protect from moisture and extreme temperatures, ventilate storerooms
Incompatibilities: Keep away from strong acids, bases, and oxidizers
Recommended materials: Use tightly sealed containers made of materials compatible with phosphinates
Exposure limits: No national occupational exposure limits established; suggested dust limit 10 mg/m³ (total), 3 mg/m³ (respirable)
Engineering controls: Use dust extraction and local ventilation
Personal protective equipment:

Flammability: Not self-igniting, will burn under strong ignition source
Explosion risk: Dust explosion possible with fine powder and air mixture
Chemical stability: Stable under recommended storage and use conditions
Thermal decomposition: Above 400°C, starts breaking down, generating hazardous gases
Hazardous reactions: Reacts with strong acids, strong bases, and oxidizing agents, generating heat
Incompatibility: Strong oxidizers, acidic or basic materials, water/moisture exposure over time
Hazardous decomposition products: Phosphorus oxides, carbon oxides, aluminum oxides, possibly hydrocarbons
Acute toxicity: LD50 (oral, rat) > 2000 mg/kg, not acutely toxic
Skin corrosion/irritation: Mild, mechanical skin irritant
Eye damage/irritation: Dust may cause redness and irritation
Respiratory effects: Dust may scratch throat, cause coughing, no chronic toxicity noted in studies
Chronic effects: Not classified as a carcinogen, mutagen, or reproductive toxicant
Other hazards: No known sensitization, no evidence of organ toxicity at normal exposure
Aquatic toxicity: Low toxicity to aquatic organisms (LC50 > 100 mg/L for fish, daphnia, algae)
Persistence and degradability: Not readily biodegradable, slow breakdown in environment
Bioaccumulation: No significant accumulation expected
Mobility: Low in soil and water, binds to particles, insoluble phase
Other effects: Avoid large releases to watercourses or soil, persistent insoluble compounds may long-term contaminate sediments
Waste treatment: Collect into containers for specialized landfill or incineration
Disposal method: Follow local, state, and national regulations for hazardous waste
Packaging disposal: Triple rinse, puncture, and recycle; contaminated packaging as hazardous waste
