Synonyms: Intumescent system, organophosphorus additive, flame retardant phosphate ester blend
GHS Classification: Sometimes labeled irritant and environmentally hazardous (may depend on specific ingredient mix)
Hazard Statements: Causes mild skin and eye irritation, possible risk of environmental persistence, may pose some risk to aquatic life
Pictograms: Exclamation mark, environment
Precautionary Statements: Wear gloves and goggles; avoid release to soil or water, do not inhale fumes, avoid contact with open wounds
Main Components: Ammonium polyphosphate (40–70%), pentaerythritol (10–25%), melamine (up to 12%), zinc borate or similar synergist (3–8%)
Impurities: Trace solvents or stabilizers below 1%
Chemical Abstracts Service Numbers (CAS): Ammonium polyphosphate (68333-79-9), Pentaerythritol (115-77-5), Melamine (108-78-1), Zinc borate (138265-88-0)
Eye Contact: Flush with clean water for at least 15 minutes, seek medical help if redness remains
Skin Contact: Wash with soapy water, remove contaminated clothing, watch for persistent irritation
Inhalation: Move to fresh air, stay calm, monitor for coughing or shortness of breath, seek medical attention if symptoms continue
Ingestion: Rinse mouth, do not encourage vomiting, drink water, get medical assistance right away
Suitable Extinguishing Media: Water spray, CO₂, dry powder, foam—avoid using high-velocity jets
Special Hazards: Fumes may release toxic gases such as carbon oxides, ammonia, or phosphorus compounds
Protective Equipment: Self-contained breathing apparatus, chemical-resistant garments, avoid breathing decomposition vapors
Specific Methods: Cool surrounding containers, use water fog to contain vapors, keep distance if combustion gets intense
Personal Precautions: Use chemical resistant gloves, goggles, dust mask or respirator, wear boots
Environmental Precautions: Block entry to sewers, immediate diking, cover with inert absorbent for spills
Methods for Clean Up: Scoop into sealable containers, rinse area with water, dispose of material as per local regulations
Handling: Work with proper ventilation—open windows or use local exhaust, wear chemical-resistant gloves, don’t eat or drink in work area, avoid dust
Storage: Keep in tightly closed containers, store in cool and dry warehouses, prevent exposure to direct sunlight, separate from food or incompatible materials like strong acids and oxidizers
Exposure Limits: No US OSHA or ACGIH established limits for the flame retardant blend, but respect limits for known dusts
Engineering Controls: Use of exhaust fans, dust collectors, and closed systems in big operations—hand mixing benefits from proper airflow
Personal Protective Equipment: Gloves, safety goggles, protective aprons, half-face dust respirator when mixing or transferring large amounts
Appearance: Fine white or off-white powder, sometimes granular
Odor: Odorless to slightly characteristic/pungent
pH (in suspension): Mildly acidic to neutral (5.5–7.5 for a 10% slurry)
Melting Point: Typically above 225°C (decomp)
Solubility in Water: Low to moderate; dispersible but not truly soluble
Density: Roughly 1.7–2.0 g/cm³
Flash Point: Non-flammable solid, self-extinguishing
Vapor Pressure: Not relevant due to solid form
Chemical Stability: Stable at room temperature, shelf life often outpaces product use
Conditions to Avoid: Avoid high heat, direct sunlight, strong oxidizers, acids and bases
Hazardous Reactions: Breakdown under fire conditions may release ammonia, oxides of nitrogen, phosphorus oxides
Incompatible Materials: Strong acids, alkalis, oxidizing agents
Acute Toxicity: Low—LD₅₀ in rats frequently above 2000 mg/kg
Chronic Exposure: No evidence for carcinogenicity or mutagenicity—prolonged skin contact may cause dermatitis in some workers
Eye and Skin Contact: Mild irritation possible, especially with handling large volumes, rare cases of sensitization
Inhalation: Dust may aggravate asthma or allergies, especially in poorly ventilated workspaces
Ingestion: Not intended for ingestion, no signs of systemic toxicity reported in routine exposures
Aquatic Toxicity: May cause harm to aquatic organisms in concentrated form, can linger in sludge
Persistence and Degradability: Further studies needed, main components tend to break down in soil but may persist in cool water
Bioaccumulative Potential: Low—molecules generally do not build up in food chains
Mobility in Soil: Moderately mobile if spilled, though blends clump in mud or clay
Methods of Disposal: Collect in sealed containers, send to authorized chemical landfill or incinerator
Special Precautions: Do not flush with water, keep out of drains and storm sewers
Container Disposal: Triple rinse empty bags or drums, scrap plastics or metal only after solid waste treatment
UN Number: Not classified as hazardous for transport under UN guidelines for these flame retardants
DOT Classification: Not regulated
Packing Group: Not applicable
Special Transport Notes: Ship in climate-protected, sealed containers to avoid moisture, keep upright to avoid caking
Inventory Listings: Most ingredients appear on major chemical inventories like TSCA (US), EINECS (EU), DSL (Canada)
Label Requirements: Chemical safety pictograms, clear product trade name and batch number, hazard phrases in local language
SARA Title III: Most non-halogenated flame retardants are not listed as extreme hazards
Other National Regulations: Restrictions vary—EU REACH requires full ingredients disclosure, labeling in accordance with CLP Regulation
Worker Protection: Corporate safety officers expected to provide regular training about dust exposure, glove changes, and spill routine
Consumer Protection: End-use foam parts labeled as “halogen free—reduced fume toxicity” under national building safety codes
