Fire-Fighting Measures

Suitable Extinguishing Media: Carbon dioxide, foam, dry chemical powder, water spray
Unsuitable Media: Full water jet may spread the product
Special Hazards: May release hazardous phosphorus oxides, nitrogen oxides under combustion
Protective Equipment: Wear self-contained breathing apparatus, full protective clothing, and gloves
Advice for Firefighters: Remove personnel from downwind areas and prevent runoff into drains or watercourses

Accidental Release Measures

Personal Precautions: Wear dust mask, gloves, goggles, and protective clothing; avoid contact with skin and eyes; remove ignition sources
Environmental Precautions: Prevent spillage from entering drains or waterways; alert authorities in case of large spills
Methods for Cleaning Up: Collect spilled material with a vacuum or by damp sweeping; place in suitable containers for disposal; ventilate area thoroughly after cleanup

Handling and Storage

Handling: Avoid contact with eyes, skin, and clothing; work in well-ventilated spaces; wash hands after use; keep containers tightly closed
Storage: Store in a cool, dry, well-ventilated area; protect from moisture, direct sunlight, and incompatible substances like strong acids or strong oxidizers; keep separate from food and drink

Exposure Controls and Personal Protection

Occupational Exposure Limits: No specific TLV identified for piperazine pyrophosphate; general dust limits for nuisance particulates may apply
Engineering Controls: Use local exhaust ventilation and process enclosures if dust generation is likely
Personal Protective Equipment: Safety glasses with side shields, chemical-resistant gloves, dust mask or respirator (P2 or N95 minimum), lab coat or coveralls
Hygiene Measures: Change contaminated clothing promptly; wash thoroughly before eating, drinking, or smoking
