Label Elements: Avoid breathing dust, rinse eyes or skin if contact occurs, keep out of environment if spilled in large quantities
Signal Word: None required for this product
Chemical Name: Ammonium Polyphosphate
CAS Number: 68333-79-9
Purity: 98% or greater
Additives: Trace antistatic or processing agents depending on grade, but not present above disclosure limits; no hazardous impurities present above regulatory thresholds
Inhalation: Move affected person to fresh air; seek medical attention if symptoms don’t clear quickly
Skin Contact: Wash skin with plenty of water; remove contaminated clothing; seek consultation for irritation
Eye Contact: Rinse immediately for at least 15 minutes; hold eyelids open; seek medical help if irritation persists
Ingestion: Rinse mouth; do not induce vomiting; drink water if conscious; contact poison control or doctor for advice
Symptoms: Temporary eye or airway irritation possible; not expected to sensitise or cause systemic effects from single exposure
Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Unsuitable Extinguishing Media: None specified for this type, but full water jet may spread spilled product
Fire Hazards: Non-combustible, product will not burn itself; decomposition at high temperature can release ammonia and phosphorus oxides
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full gear
Hazardous Combustion Products: Ammonia, phosphorus oxides gases possible on strong heating
Personal Precautions: Avoid raising dust; ventilate area; use suitable dust mask
Spill Cleanup Methods: Collect material mechanically or with vacuum; sweep up and transfer to container for recovery or disposal
Environmental Precautions: Prevent large spills from entering drains or surface water; notify authorities if above significant quantity
Disposal Considerations: Dispose of spilled product in accordance with local regulations for non-hazardous chemicals
Handling: Use in well-ventilated area; minimize dust generation; avoid contact with eyes; wash hands after use
Hygiene Measures: Do not eat or drink during use; remove contaminated clothing before entering eating areas
Storage: Store in original sealed container; keep cool and dry; avoid exposure to strong acids and bases
Incompatibilities: Protect from moisture; keep away from strong alkalies, acids, and reducing agents
Exposure Limits: No specific occupational limits for this compound; keep exposure as low as reasonably achievable
Engineering Controls: Local exhaust ventilation if dust forms
Personal Protective Equipment: Safety glasses, dust mask (P2 or N95), gloves, lab coat or overalls
Skin Protection: Use gloves for extended contact
Eye Protection: Use goggles or face shield with dust exposure
Respiratory Protection: Mask with particulate filter for high dust environments
Appearance: White to off-white powder or granules
Odor: Odorless
Melting Point: >240°C (decomposes)
Solubility: Slight (0.1-0.5% in water)
pH Value: 6-8 (10% aqueous suspension)
Vapor Pressure: Not applicable
Density: About 1.9 g/cm³
Flash Point: Not applicable
Decomposition Temperature: Begins >240°C
Other Data: Stable under normal conditions, will cake in moist air
Chemical Stability: Stable if kept dry
Instability Conditions: Moisture leads to caking, decomposition possible with acids or bases
Hazardous Reactions: Contact with strong reducing agents might cause slow breakdown; strong acids generate ammonia gas
Hazardous Decomposition Products: At high temperatures, releases ammonia and phosphorus oxides
Incompatibility: Strong acids and alkalies
Acute Toxicity: Oral LD50 (rat): >5000 mg/kg; considered practically non-toxic
Inhalation: No data on acute inhalation toxicity, but dust may irritate airway
Skin Irritation: Not classified as irritant in rabbit testing
Eye Irritation: Mild and reversible irritation possible
Chronic Effects: Not expected to cause chronic health effects under normal handling
Carcinogenicity, Mutagenicity, Teratogenicity: No evidence or suspicion in published studies
Acute Aquatic Toxicity: LC50/EC50 values >100 mg/L for fish, daphnia, algae
Persistence and Degradability: Not readily biodegradable; product consists mainly of inorganic phosphorus
Bioaccumulation: No potential for bioaccumulation
Mobility in Soil: Low solubility and tendency to bind to soil particles
Environmental Fate: Deposit settles in sediment without significant biological effect; large spills in water bodies may impact nutrient balance
Disposal Methods: Dispose of as non-hazardous mineral waste; follow local and national regulations
Container Disposal: Empty containers can be sent for recycling or disposal, provided all residues are removed
Precautions: Avoid release to natural water sources or soils in large quantities; collect and label all waste packaging appropriately
