Suitable Extinguishing Media: Water spray, dry chemicals, carbon dioxide, foam
Unsuitable Media: Water stream may spread molten polymer
Hazardous Combustion Products: Burning generates carbon monoxide, carbon dioxide, possible toxic and irritating halogenated compounds and antimony vapors, hydrogen bromide or other byproducts depending on flame retardant formula
Protective Equipment for Firefighters: Full self-contained breathing apparatus and protective clothing
Special Firefighting Instructions: Evacuate downwind areas, cool adjacent containers, fight from a safe distance
Explosion Risk: Molten polymer spills may cause slippery conditions, potential vapor buildup in enclosed spaces can create dangerous scenarios.
Personal Precautions: Wear gloves, safety goggles, dust mask if fine dust generated
Environmental Precautions: Prevent pellets or powders from entering water sources, soil, drains; spilled materials become significant environmental contaminants in aquatic systems
Clean Up Methods: Shovel, vacuum, or sweep up spilled pellets to avoid slip hazards and environmental release; store in appropriate containers for later disposal or recycling
Incident Response: Notify supervisors and safety officers immediately upon discovery of a significant spill or powder release
Minor Leaks: Grab spilled pellets by hand or with sweepers; for powders, use HEPA-filtered vacuum
Handling: Keep away from flames or high temperatures, ventilate work areas especially during processing, avoid breathing fumes, don’t eat or drink in processing zones, enforce use of gloves and safety glasses
Storage Conditions: Store in tightly sealed containers in a cool, dry, vented place, away from sunlight and incompatible materials such as oxidizing agents; keep away from moisture to prevent product degradation
Separation: Don’t store next to food, feed, or strong chemicals
Incompatibilities: Avoid exposure to acids, oxidizers, and strong bases
Bulk Storage: Use silos or well-labelled bags on pallets to prevent moisture exposure, pests, or accidental mixing
Exposure Limits: OSHA/ACGIH limits set for dust (10 mg/m³, total dust) and specific flame retardants (e.g., antimony trioxide: 0.5 mg/m³ TWA)
Engineering Controls: Local exhaust ventilation required at points of fume or dust generation
Respiratory Protection: Minimum: dust mask or half-face respirators with P2 filters; in case of fumes during thermal processing, air-purifying respirators or supplied air units
Hand Protection: Chemical-resistant gloves
Eye Protection: Safety glasses or face shield when handling pellets or powders
Skin Protection: Long-sleeved workwear
General Hygiene: Wash hands after handling, keep separate from food storage, avoid touching face or eyes on the job
Appearance: White or off-white pellets or granules
Odor: Faint or odorless
Odor Threshold: Not distinct at room temperature
pH: Not applicable (solid polymer blend)
Melting Point/Range: 130 - 170°C
Boiling Point: Not applicable
Flash Point: >350°C (estimated)
Evaporation Rate: Non-volatile
Flammability: Normally self-extinguishing due to flame retardant
Vapor Pressure: Not applicable
Density/Specific Gravity: 0.9 - 1.2 (varies with loading of additives)
Solubility: Insoluble in water
Viscosity: Not relevant in solid state
Partition Coefficient: Not measured for blend
Decomposition Temperature: >250°C
Particle Size: Usually 2-5 mm for pellets
Stability: Stable under room temperature and normal storage conditions
Reactivity: Not chemically reactive under standard usage
Decomposition: Thermal decomposition releases carbon monoxide, hydrocarbons, smoke, hydrogen bromide, antimony compounds, and other hazardous fumes unique to flame retardant chemistry
Incompatible Materials: Strong oxidizers, acids, and bases
Hazardous Polymerization: Not anticipated under recommended handling
Conditions to Avoid: Heating above decomposition temperature, open flames, sparks
Acute Toxicity: No acute toxicity from solid form; specific additives (e.g., antimony trioxide, brominated compounds) bring potential chronic health risks (inhalation of fine dust, extended exposure)
Skin Irritation: Pellets rarely cause irritation, but powder or molten forms may irritate or burn
Eye Effects: Pellets can be physical irritants, fumes can injure the eyes on prolonged exposure
Chronic Effects: Certain flame retardants show links to reproductive or developmental toxicity, carcinogenicity (antimony compounds, halogenated organics)
Inhalation Toxicity: Dust or fume inhalation linked to lung irritation, possible respiratory sensitization depending on additive
Ingestion Risk: Low for accidental, but not intended for consumption
Mutagenicity/Teratogenicity: Specific flame retardants (some brominated, or antimony compounds) flagged for higher concern in some studies
Medical Conditions Aggravated: Known respiratory problems or chemical sensitization exacerbated with exposure
Ecotoxicity: Most PP masterbatches are non-toxic to terrestrial life in pellet form, but flame retardant chemicals present concerns to aquatic life (bioaccumulative, toxic to certain aquatic species, persistent in water)
Persistence/Degradability: Polypropylene does not break down rapidly; flame retardants can persist much longer in the environment
Bioaccumulation: Many brominated flame retardants bioaccumulate in soil, water, and living organisms
Mobility in Soil: Solid pellets settle, but powder and residuals can move with stormwater
Special Concerns: Flame retardants leaching from microplastics seen as a growing environmental problem globally
Other Notes: Efforts to collect and recycle spilled pellets and clean dust from production spaces limit environmental contamination.
Waste Handling: Collect and recover as much material as possible for recycling routes if allowed
Disposal Methods: General landfill not recommended for large amounts; incineration possible but only with adequate air cleaning to capture halogenated or antimony emissions
Regulations: Disposal should follow national, regional, and local environmental regulations for hazardous waste; some flame retardants require special listing or registration
Packaging: Contaminated containers disposed as hazardous waste or returned to supplier for reprocessing
Reuse/Recycling: Material recovery programs set up in some jurisdictions for large manufacturing operations
Spill Recovery: All recovered pellets or contaminated sweepings gathered and placed in labelled containers for approved waste routes
UN Number: No specific UN number, unless classified as hazardous due to additive content
Proper Shipping Name: Polymer Additive or Polypropylene Masterbatch
Hazard Class: Not classified under ADR, IMDG, IATA when supplied in pellet form, but additional labeling needed for high concentrations of regulated flame retardant
