Label Elements: Flame, Exclamation Mark, Environment Symbol
Red Phosphorus Content: 25%–60% by weight
Polymer Carrier: Polypropylene or Polyethylene, 35%–70% by weight
Stabilizers and Additives: <5%, proprietary blend
Main Hazard Component: Red Phosphorus (CAS 7723-14-0)
Impurities: Less than 0.1% white phosphorus, trace stabilizer residues
Inhalation: If exposed to dust, move to fresh air, keep at rest, seek medical advice if symptoms persist
Skin Contact: Wash immediately with plenty of water and mild soap, remove contaminated clothing
Eye Contact: Rinse carefully with water for several minutes, remove contact lenses, consult a doctor if irritation continues
Ingestion: Rinse mouth, do not induce vomiting, seek immediate medical assistance
Suitable Extinguishing Media: Dry sand, Class D fire extinguisher, do not use water or foam on phosphorus
Special Hazards: Burning releases toxic phosphorus oxides and phosphine gas, possible explosive reaction with oxidizers
Protective Equipment for Firefighters: Self-contained breathing apparatus, full protective clothing
Firefighting Advice: Move containers from fire area if safe, keep unaffected material cool with dry sand barriers, avoid inhaling fumes
Personal Precautions: Evacuate area, ventilate if indoors, avoid breathing dust, wear respiratory protection and gloves
Environmental Precautions: Prevent material entering drains, sewers, or surface water
Cleanup Methods: Collect spilled product using non-sparking tools and inert material (sand, vermiculite), store in dry, sealed containers for disposal
Disposal Guidance: Label all waste, do not allow contamination with combustible materials
Handling: Avoid creating dust, handle away from heat or spark sources, ground equipment, wear recommended personal protective equipment
Storage Conditions: Store in cool, dry, well-ventilated place, away from sunlight, oxidizing agents, acids, and bases
Storage Containers: Use original containers, tightly sealed, label area as red phosphorus hazard zone
Other Precautions: Keep product dry at all times, restrict access to trained personnel
Exposure Limits: OSHA PEL: 0.1 mg/m³ (as phosphorus)
Engineering Controls: Local exhaust ventilation, explosion-proof equipment
Personal Protective Equipment: Safety goggles, chemically resistant gloves, flame-resistant work clothing, respirator where dust is generated
Hygiene Measures: Wash hands thoroughly after handling, no food or drink in work areas
Appearance: Red, purple, or brownish granules
Odor: Odorless
pH: Not applicable
Melting Point: Red Phosphorus: ~590°C (sublimes)
Boiling Point: Not determined
Density: 1.0–1.5 g/cm³ (depends on carrier resin)
Solubility: Insoluble in water and most solvents
Flash Point: Above 240°C (red phosphorus component)
Explosion Properties: Dust may form explosive mixtures with air under certain conditions
Other Properties: Stable under recommended storage, not hygroscopic if container remains sealed
Chemical Stability: Stable under normal temperatures and pressures, sensitive to shock and friction in dry conditions
Reactivity: Reacts violently with strong oxidizers, halogens, and acids
Hazardous Decomposition Products: Phosphorus oxides, phosphine gas
Conditions to Avoid: Heat, open flame, sparks, contact with oxidizing chemicals, moisture for prolonged periods
Incompatibility: Avoid contact with strong bases, acids, and oxidizing agents
Acute Toxicity: Inhalation of dust may cause respiratory tract irritation, ingestion may cause severe gastrointestinal irritation
Skin Irritation: Direct contact can produce irritation or burns
Eye Effects: Dust contact produces eye irritation, possible conjunctivitis
Chronic Effects: Long-term exposure to phosphorus dust linked to bone/jaw necrosis (“phossy jaw”) in industrial situations
Carcinogenicity: Not classified as carcinogenic by IARC, ACGIH, OSHA, NTP
Other Info: No evidence for reproductive toxicity under normal exposure levels
Aquatic Toxicity: Harmful to aquatic organisms, prolonged exposure damages aquatic ecosystems
Persistence and Degradability: Red phosphorus is not easily soluble and settles in sediment, slow degradation
Bioaccumulation: Unlikely due to low solubility
Other Adverse Effects: Combustion products hazardous to aquatic life, phosphorus cycle impacts if released at large scale
Waste Treatment Methods: Collect as dangerous waste, do not dispose of with normal garbage
Recommended Disposal: Incinerate in controlled facility, observe national/local regulations
Container Disposal: Empty containers retain residue, treat as hazardous, rinse only with approval
Precautions: Always wear full PPE during handling and disposal, clearly label discards to prevent mixing with reactive materials
