Hazard Statements: Eye contact causes redness, skin may itch or redden, inhalation may irritate throat, dust can aggravate asthma
Pictograms: Exclamation mark (may induce irritation), environmental toxicity symbol for aquatic hazards
Precautionary Statements: Use with adequate ventilation, avoid swallowing, keep dust generation low, wash hands after handling
Main Components: Modified ammonium polyphosphate (CAS Number: 68333-79-9) 60–80%, Aluminum hydroxide (CAS Number: 21645-51-2) 10–20%, Proprietary Synergist Package 1–5%, Hydrated silicates 5–10%, Minor inert fillers
Impurities: No heavy metals above 0.01%, trace moisture from manufacture
Additional Ingredients: Surface conditioning agents, antistatic helper (proprietary, less than 1%)
Eye Contact: Flush with water for at least fifteen minutes, keep eyelids lifted, monitor for vision changes, see physician if uncomfortable
Skin Contact: Wash affected skin using warm water and mild soap, remove contaminated clothing, moisturize if dryness occurs
Inhalation: Breathe fresh air, loosen tight clothing, rest in area with good airflow, seek medical advice if cough or headache persists
Swallowing: Rinse mouth thoroughly, do not induce vomiting, drink water, contact physician if large amount swallowed or symptoms last
Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide
Hazardous Combustion Byproducts: Phosphorous oxides, nitrogen oxides, aluminum oxide dust, low toxicity smoke
Protective Equipment: Full face shield, self-contained breathing apparatus recommended, gloves that prevent powder contact
Unusual Hazards: Product slows flame spread but large fires may still generate irritating gases; run-off may be slippery
Personal Precautions: Wear dust mask, goggles, long sleeves, avoid breathing powder clouds, do not touch eyes
Environmental Precautions: Prevent spreading to drains or open waterways, avoid releasing large quantities outdoors
Spill Cleanup Methods: Scoop into plastic or lined containers, vacuum remaining dust with HEPA filter system, ventilate area before resuming work, wash spill surface with soapy water
General Handling: Pour and handle in well-ventilated areas, use gloves to protect skin, wear mask if dust becomes visible, avoid generating dust by using appropriate scooping and pouring techniques
Storage Requirements: Store in tightly sealed containers, keep away from heat and sources of ignition, avoid stacking over 2 meters deep, prevent direct sunlight exposure, recommended storage temperature under 30°C, keep containers dry and off damp floors
Special Sensitivity: Avoid contact with oxidizers and acids, moisture exposure clumps product, do not store near food or animal feed
Occupational Exposure Limits: Ammonium polyphosphate 10 mg/m³ (inhalable dust, TWA), aluminum hydroxide 5 mg/m³ (respirable fraction)
Engineering Controls: Exhaust fans at handling points, closed transfer systems, grounded equipment to prevent static discharge
Personal Protective Equipment: Nitrile gloves, dust mask conforming to NIOSH N95 or higher, chemical splash goggles, lab coat or disposable overall, workplace showers and eye wash stations available
Special Safety Measures: Wash hands after handling, clean worksurfaces often to avoid buildup, never eat or smoke before removing dusty clothing
Form: Fine powder, sometimes granular
Color: White to off-white
Odor: Almost none, very faintly chemical
pH (1% in water): 5.5–7.5
Melting Point: Greater than 200°C (mostly decomposes, doesn’t melt)
Solubility in Water: Low (less than 2% at room temperature)
Bulk Density: 500–850 kg/m³
Vapor Pressure: Not applicable (solid powder)
Decomposition Temperature: Starts above 300°C
Chemical Stability: Stable under normal conditions, not reactive at room temperature
Conditions to Avoid: High humidity, prolonged heat above 200°C, open flames, direct acid or strong alkali contact
Incompatible Materials: Strong acids (releases ammonia gas), strong oxidizers
Hazardous Decomposition Products: Phosphorous oxides, ammonia, NOx, water vapor, and aluminum oxides in fire or extreme heating
Possible Routes of Entry: Inhalation, skin/eye contact, swallowing
Acute Effects: Eye and throat irritation, dry or itchy skin after prolonged exposure, mild upset stomach if accidentally eaten
Chronic Effects: Repeated dust exposure can worsen asthma, no evidence of cancer in animal studies, rare allergic skin response
Toxicity Data: LD50 (rat, oral, ammonium polyphosphate) > 5000 mg/kg; data suggest low systemic toxicity
Sensitization: Very low risk, though some sensitive individuals may report dryness or patchy skin
Aquatic Toxicity: Product itself shows low immediate toxicity to aquatic life, phosphorus content may contribute to algal growth if discharged in quantity
Mobility in Soil: Stays near surface, very slow migration
Persistence and Degradability: Not readily biodegradable, minerals persist; phosphate part eventually used by plants
Bioaccumulation Potential: No significant bioaccumulation expected for principal ingredients; some trace compounds may accumulate in certain conditions
Other Effects: High concentrations may upset local water chemistry if released in bulk
Waste Disposal Method: Dispose as non-hazardous industrial solid waste, landfill if local laws allow, avoid dust clouds during transport
Container Disposal: Rinse emptied pails or bags thoroughly, recycle or landfill per municipal requirements
Special Precautions for Disposal: Don’t flush bulk quantities into sewer, check community phosphate limits before bulk disposal, always log disposal volume
UN Number: Not regulated as dangerous goods by air, road, sea under normal handling
Proper Shipping Name: Flame retardant, inorganic, powder
Hazard Class: Non-hazardous for transport (as per US DOT, IATA, IMDG)
Packaging: Store in strong, sealed bags or drums, keep dry during transit
Special Transport Precautions: Avoid tearing bags, stack carefully to prevent collapse, mark packaging with product name and contact phone in case of spillage
Regulatory Status: Ingredients listed on TSCA, REACH, DSL, and AICS chemical inventories
Labelling Requirements: Product label must show hazard warning, handling advice, and emergency contact details
OSHA Classification: Considered nuisance dust, not classified as toxic or carcinogenic
SARA Title III: No listed components at reportable thresholds
Europe (REACH): Registered, no restriction for intended use
RoHS/WEEE Status: No restricted substances present above regulatory thresholds
Other Legal Notes: Always check local workplace and environmental regulations for permitted dust exposure and discharge, update supplier SDS annually
