Main Routes of Exposure: Inhalation, skin and eye contact
Precautionary Statements: Avoid breathing dust, use with adequate ventilation, wash hands thoroughly after handling, keep away from sources of ignition
Main Component: Red Phosphorus (CAS 7723-14-0), typically 10–50% by weight
Carrier Resin: Polyolefin, polyamide, polyester, or proprietary polymer base (Chemical-specific CAS numbers provided by supplier per formulation), typically 40–90% by weight
Stabilizers and Antioxidants: Proprietary, commonly calcium carbonate, magnesium oxide, or lead-free stabilizers (1–5%)
Impurities: Trace phosphorus oxides from oxidation, minute quantities of residual monomers
Hazardous Ingredients: Red Phosphorus listed as flammable solid, may include proprietary substances considered irritants
Inhalation: Move affected person to fresh air, keep at rest and seek medical attention if symptoms persist, provide oxygen if breathing is difficult, avoid mouth-to-mouth resuscitation
Skin Contact: Immediately remove contaminated clothing and wash skin thoroughly with soap and cool water for at least 20 minutes, seek medical advice for irritation or burns
Eye Contact: Rinse eyes carefully for 15 minutes with plenty of water, remove contact lenses if safe, call physician if irritation persists
Ingestion: Rinse mouth with water, do not induce vomiting, never give anything by mouth to an unconscious person, seek immediate medical help
Notes for Doctors: Treat symptomatically for chemical irritation, consider delayed pulmonary edema for significant exposures
Suitable Extinguishing Media: Use sand, dry powder extinguishers, or Class D fire agents for phosphorus fires, water spray can be used for surrounding materials but not directly on the red phosphorus
Unsuitable Media: Do not use water jets or carbon dioxide directly on burning red phosphorus due to risk of violent reaction and spread
Fire Hazards: Decomposition releases toxic phosphorus oxides and phosphine gas, which are dangerous to inhale, product dust forms explosive mixtures with air, can reignite after flames are extinguished
Protective Equipment: Full protective firefighting gear, self-contained breathing apparatus recommended, evacuate area in case of large fire
Special Procedures: Contain runoff from firefighting, do not allow to enter drains or watercourses, isolate area upwind if possible
Personal Precautions: Wear chemical-resistant gloves, dust masks or respirators (P2 or P3 filters), safety goggles, and antistatic clothing, restrict access to affected area
Environmental Precautions: Prevent material from entering drains, surface waters, or soil, alert appropriate authorities if a significant spill occurs
Containment Methods: Collect spilled granulate using non-sparking tools and place in secure containers, avoid creating dust clouds, use vacuum equipment with HEPA filters for cleanup
Cleanup Methods: Avoid sweeping or pneumatic conveyance; dampen solids before sweeping to minimize dust, ventilate the area thoroughly after cleanup
Disposal: Dispose of collected material as hazardous chemical waste in accordance with local and national regulations
Handling: Use only in a well-ventilated area, wear appropriate PPE including gloves and dust mask, avoid inhaling dust or fumes, ground all equipment to dissipate static electricity, avoid sources of ignition and open flames, do not eat, drink, or smoke around material, keep containers tightly closed when not in use
Storage: Store in a cool, dry, well-ventilated, flameproof location, away from strong oxidizing agents, acids, and direct sunlight, separate from incompatible materials including potassium chlorate, potassium nitrate, or other strong oxidizers, use only tightly sealed, labeled containers, store away from foodstuffs and animal feeds, prevent build-up of static electricity, check periodically for leaks, deterioration or container damage
Occupational Exposure Limits: ACGIH TLV for red phosphorus particulate – typically 0.1 mg/m³ (consult local industrial hygiene limits), check for specific jurisdictional limits
Engineering Controls: Local exhaust ventilation recommended, enclosures for mixing or dispensing, explosion-proof electrical systems if handling large quantities
Personal Protection: Chemical-resistant gloves (nitrile or neoprene), safety goggles or wraparound glasses, particulate-filtering respirators during agitation or spill cleanup, flame-retardant lab coats or antistatic overalls, emergency eyewash and safety shower accessible
Hygiene Measures: Wash exposed skin thoroughly before eating, smoking, or using restroom, maintain good housekeeping to limit dust accumulation, launder contaminated clothing before reuse
Environmental Controls: Avoid emission of particulates into air or wastewater, install particulate filters or scrubbers if needed
Appearance: Granulated, colored pellets (red, dark red, or violet hues, depending on formulation)
Odor: Slight, sometimes garlic-like if phosphorus vapor is present
pH: Not applicable (solid)
Melting Point: Carrier dependent, typically 110–170°C for polyolefin-based, red phosphorus softens near 590°C
Boiling Point: Decomposes before boiling
Flash Point: Approx. 260–320°C
Ignition Temperature: >260°C (may be lower for dust clouds)
Explosion Properties: Dust dispersed in air can explode if ignited, Kst and Pmax parameters depend on composition
Vapor Pressure: Negligible at room temperature
Solubility: Insoluble in water, partial solubility in strong solvents or acids
Density: Typically 1.35–1.65 g/cm³
Partition Coefficient (n-octanol/water): Not applicable
Stability: Stable under recommended storage and handling, decomposes on strong heating or in the presence of oxidizing agents
Chemical Stability: Stable under cool, dry, inert storage conditions, shelf life variable based on packaging integrity
Reactivity: Intense reaction with oxidizers, halogens, chlorates, peroxides, acids, release of heat and toxic gases in contact with incompatible substances
Condition to Avoid: Elevated temperatures, sparks, open flames, static discharge, incompatible chemicals
Incompatible Materials: Strong oxidizers (e.g., potassium permanganate, sodium chlorate), acids, chlorine, peroxides, moisture
Decomposition Products: Phosphorus oxides (P2O5, P4O10), phosphine gas (dangerous by inhalation), carrier breakdown products dependent on polymer base
Acute Toxicity: Red phosphorus LD50 (oral, rat): ~300 mg/kg, inhalation LC50 (rat): ~0.085 mg/L/4h, primary effects via dust inhalation and ingestion
Skin Irritation: Risk of burns and dermatitis on repeated or prolonged contact
Eye Effects: Serious eye irritation and risk of burns
Respiratory Effects: Inhalation may cause choking, coughing, delayed pulmonary edema
Chronic Effects: Prolonged or repeated exposure may affect nervous system, liver, jaw bone (phossy jaw documented in industrial exposures), skin sensitization possible
Carcinogenicity: Not listed as human carcinogen by IARC, NTP, or OSHA, but repeated exposure raises cancer risk in animal experiments
Other Risks: May cause gastrointestinal upset, nausea, vomiting after ingestion, possible effects on kidney and liver with heavy exposure
Aquatic Toxicity: Toxic to fish and aquatic invertebrates, phosphorus oxides contaminate water and lower pH, potential for long-term effects from carrier polymer toxicity
Persistence: Red phosphorus converts slowly in environment, residual particles persist in sediment, carrier plastics may fragment but do not degrade quickly
Bioaccumulation: Limited evidence; phosphorus is not believed to bioaccumulate, but some carrier chemicals may build up in aquatic animals indirectly
Mobility: Phosphorus particles sink in water, may move through soil if spilled outdoors
Other Adverse Effects: Wastewater and dust emissions can harm wastewater treatment biota, risk of oxygen depletion in receiving streams
Waste Treatment Methods: Collect residues and contaminated packaging, incinerate in approved facility under controlled conditions, treat as hazardous waste, avoid landfill disposal
Special Precautions: Do not pour into drains, water bodies or on soil, contaminated absorbents require hazardous waste labeling
Recycling: Some carrier resins may be recycled by specialty firms, consult authorities for phosphorus component disposal
Regulations: Disposal controlled under local, regional, and national hazardous waste regulations, seek authorized chemical waste contractor
Packaging: Rinse thoroughly if recycled, otherwise dispose with chemical waste following all safety measures
