Signal Word: Danger
Routes of Exposure: Inhalation, skin and eye contact
Pictograms: Fire, health hazard, environment hazard
Substance: Mixture
Main Ingredients: Red Phosphorus (CAS No. 7723-14-0, 20–60%), Polyolefin Carrier (CAS No. Confidential, 40–75%), Additives (antioxidants, dispersants 1–5%)
Impurities: Trace metal oxides, phosphorus oxides (as manufacturing residues)
Inhalation: Move affected person to fresh air, keep comfortable, seek medical attention for breathing issues
Eye Contact: Rinse cautiously with clean water for over fifteen minutes, remove contact lenses, continue rinsing
Skin Contact: Strip contaminated clothing, wash exposed skin thoroughly with soap and lukewarm water, seek medical advice if irritation persists
Ingestion: Rinse mouth, do not induce vomiting, consult a physician or poison center immediately
Special Advice to Doctor: Treat symptomatically, monitor for delayed respiratory effects
Extinguishing Agents: Dry sand, powdered graphite, class D extinguishing agents; never use water or foam directly
Fire Hazards: Red phosphorus may ignite under heat or upon contact with chemicals like oxidizers, produces toxic fumes including phosphine, oxides of phosphorus when burning
Protective Equipment: Wear self-contained breathing apparatus, chemical protective clothing, keep upwind of fire
Advice: Remove containers from fire area if without risk; cool fires with dry agents, avoid splashing burning material
Personal Precautions: Ventilate area, avoid breathing dust, wear gloves, protective clothing, safety goggles, dust mask or respirator
Environmental Precautions: Prevent release into watercourses, drains, or soil, block any sewers
Spill Clean-Up: Gently collect spilled masterbatch using tools that do not cause sparks, transfer to dry, labeled containers for safe disposal, wash area with plenty of water (only if safe to do so), report large spills to environmental authorities
Handling: Use only in well-ventilated places, handle with care to avoid friction, impact, or static discharge, keep away from heat, flames, oxidizing agents, acids
Storage Conditions: Store in a cool, dry, fireproof area, away from sources of ignition, incompatible substances, keep container tightly sealed, avoid direct sunlight, use only explosion-proof equipment in storage areas
Packaging: Store in antistatic, moisture-proof packaging, label clearly, prevent physical damage to bags
Engineering Controls: Local exhaust ventilation, dust extraction, explosion-proof equipment
Exposure Limits: OSHA/ACGIH TLV for phosphorus dust (0.1 mg/m3, varies by region)
Personal Protective Equipment: Chemical resistant gloves, long-sleeved garments, dust mask or respirator (P2 or P3 filter), splash-proof safety goggles
Hygiene Measures: Wash hands after handling, do not eat, drink, or smoke in work area, remove contaminated clothing immediately
Form: Pelletized or granular solid
Color: Reddish-brown
Odor: Nearly odorless
Melting Point: Softens above 550°C
Solubility: Insoluble in water
Flammability: Easily ignited by friction or heat
Density: Approx. 1.5–1.8 g/cm³
pH: Not applicable
Vapor Pressure: Negligible at room temperature
Stability: Stable under recommended storage and handling conditions
Reactivity: Reacts strongly with oxidizers, may ignite under heat, shock, or friction
Hazardous Reactions: May emit phosphine and irritating fumes in fire or decomposition
Conditions to Avoid: Excess heat, moisture, acids, oxidizing agents
Incompatible Materials: Peroxides, halogens, metal oxides, strong acids/bases
Acute Toxicity: May cause irritation to respiratory tract, eyes, and skin, ingestion can cause abdominal pain, vomiting, CNS symptoms
Chronic Effects: Prolonged exposure may cause dermatitis, respiratory sensitization, organ effects
Sensitization: Dust can sensitize airways
Carcinogenicity: Not classified as a carcinogen by OSHA, IARC
Other Effects: Repeated contact increases risk of toxicity; inhalation routes especially concerning for workers
Aquatic Toxicity: Toxic to aquatic organisms, persistent in environment, avoid contamination of waterways
Persistence/Degradability: Red phosphorus is fairly stable, limited biodegradability
Bioaccumulation Potential: Low for polymer-bound phosphorus, but still risk to aquatic organisms
Mobility in Soil: Binds to soil particles, not readily mobile
Other Adverse Effects: Degradation products may be hazardous in large quantities to aquatic and terrestrial environments
Waste Treatment Methods: Send to licensed hazardous waste disposal facility, do not dump into drains or environment
Container Disposal: Empty packaging can carry residue and must be treated as hazardous, puncture and triple-rinse before disposal
Recycling Recommendation: If feasible, reclaim for industrial use following all legal controls
Regulatory Requirements: Local, state, and national regulations dictate disposal, consult current provisions
