Protective Equipment for Firefighters: Full protective equipment, self-contained breathing apparatus (SCBA), heat-resistant suit
Firefighting Procedures: Approach upwind, contain runoff to avoid environmental contamination, cool adjacent sealed containers
Combustion Byproducts: Phosphorus pentoxide, ammonia, nitrogen oxides, carbon monoxide (incomplete combustion scenarios)
Personal Precautions: Use gloves, goggles, and dust masks; remove unnecessary personnel, prevent inhalation or direct skin/eye contact
Environmental Precautions: Keep product and contaminated run-off from entering drains, soil, surface or groundwater systems
Containment Methods: Stop leak if safe, use inert absorbent materials, avoid raising dust clouds
Cleanup Procedures: Collect product with clean plastic shovel or HEPA-filtered vacuum into labeled containers, ventilate area, wash residual area with mild detergent
Disposal: Handle as hazardous waste, refer to waste disposal section for specific regulations pertinent to location
Incompatible Materials at Site: Strong oxidizers, acids, alkalis, avoid mixing spills with reactive substances
Handling: Wear gloves, goggles, and protective clothing; avoid contact with eyes/skin and inhalation of dust; use only in thoroughly ventilated areas; do not eat, drink, or smoke while handling
Storage Conditions: Store in cool, dry, well-ventilated locations, keep containers tightly sealed, protect from humidity and direct sunlight
Other Storage Practices: Segregate from foodstuffs and incompatible materials, ensure clear labeling and secondary containment for large bulk storage
Recommended Shelf Life: Two years in sealed original container at room temperature
Occupational Exposure Limits: No specific limits established for piperazine pyrophosphate; general dust: ACGIH TLV = 10 mg/m3 (inhalable), OSHA PEL = 15 mg/m3 (total dust)
Engineering Controls: Provide local exhaust ventilation, mechanical air exchanges in closed environments; use HEPA filters for dust extraction
Personal Protective Equipment—Respiratory: NIOSH-approved particulate respirators (e.g., N95 or P100) when dust exposure exceeds recommended limits
Personal Protective Equipment—Skin: Chemical-resistant gloves (nitrile or PVC), long sleeves, barrier cream
Personal Protective Equipment—Eyes: Chemical splash goggles or safety glasses with side shields
