Inhalation: Move person to fresh air, keep at rest in position comfortable for breathing, seek medical help if symptoms like coughing or shortness of breath occur
Skin Contact: Remove contaminated clothing, wash skin with copious water and mild soap for 15 minutes, get medical advice for blistering or persistent redness
Eye Contact: Rinse with water for at least 15 minutes; remove contact lenses if present; if irritation persists, consult a physician
Ingestion: Do not induce vomiting, rinse mouth with water only, never give anything by mouth if the person is unconscious, call poison control or doctor promptly
General Advice: Remove victim from exposure source as soon as possible, avoid direct handling, show this sheet to attending doctor
Suitable Extinguishing Media: Dry sand, Class D fire extinguishing agent, do not use water or CO₂
Unsuitable Media: Water and foam cause violent reaction with red phosphorus, increasing risk of explosion
Special Hazards: Toxic phosphine gas may evolve under fire conditions, dense fumes can severely impair vision and breathing
Protective Measures: Firefighters need full protective clothing and self-contained breathing apparatus
Combustion Products: Burning emits phosphorus oxides, phosphine gas, soot, and polymer fumes
Evacuation: Keep uninvolved people far away, watch for reignition
Personal Precautions: Wear respirator, gloves, flame-resistant clothing, and safety goggles
Avoid Release To Environment: Prevent spillage from reaching drains, soil, or bodies of water
Cleanup Methods: Gently scoop spilled material into clean metal or plastic containers with spark-proof tools
Containment: Shut off all ignition sources, avoid raising dust clouds
Disposal: Place waste in labeled hazardous material container for regulated disposal
Decontamination: Clean surface thoroughly with water after spill is contained
Handling: Wear antistatic clothing, avoid friction, do not eat or drink while working, wash hands before breaks
Precautions: Use only in ventilated areas, keep containers tightly closed, avoid generating dust
Storage: Store in cool, dry, flameproof warehouse; keep at 5–30°C, away from acids, alkalis, oxidizing materials, or moisture
Container Materials: Use high-density polyethylene or metal containers with tight lids
Separation: Keep away from food, feed, and incompatible substances
Labeling: Storage areas need clear hazard signage, dedicated fire extinguisher on site
Permissible Exposure Limits: OSHA PEL (as total phosphorus): 0.1 mg/m³ (TWA)
Engineering Controls: Use explosion-proof local exhaust ventilation, maintain negative pressure
Personal Protection: Respirator approved for particulate phosphorus (N95 or P100), chemical-resistant gloves (nitrile or neoprene), safety goggles, flame-retardant lab coat
Hygiene Measures: Shower and change clothes after handling, keep work and eating areas strictly separated
Monitoring Procedures: Routine area air sampling and personal exposure testing recommended
Appearance: Reddish-brown pellets or granules
Odor: Odorless under normal conditions
Melting Point: Not applicable (masterbatch format); red phosphorus melts at 590°C
Boiling Point: Decomposes before boiling
Density: 1.2–1.6 g/cm³
Solubility: Insoluble in water, insoluble in most organic solvents
Vapor Pressure: Negligible at room temperature
Flash Point: >250°C (due to carrier resin); pure red phosphorus ignites at 260°C
Flammability: Supports combustion above 262°C
Stability in Sunlight: May darken upon exposure, but remains stable under sealed storage
Chemical Stability: Stable in closed containers at ambient temperatures
Hazardous Reactions: Contact with oxidizers, acids, or alkalis may cause violent reaction
Incompatibility: Oxidizing agents, halogens, strong acids, caustics
Decomposition Products: Phosphine, phosphorus oxides, hydrocarbons if overheated or burned
Polymerization: Not expected to occur under normal uses
Routes of Exposure: Inhalation (dust), skin, eye, ingestion
Acute Toxicity: Harmful if swallowed; estimated LD50 (rat, oral, red phosphorus): 1,200 mg/kg
Skin Sensitization: Prolonged or repeated contact may cause allergic dermatitis
Eye Effects: Irritating to eyes, high doses may damage cornea
Respiratory Effects: Can irritate airways, coughing, tightness in chest
Chronic Effects: Chronic exposure may impair liver or kidney, may lead to "phossy jaw" in severe industrial exposures
Mutagenicity/Carcinogenicity: No evidence of carcinogenicity, not classified as a mutagen
Target Organ Effects: Liver, kidney, bones (in severe cases)
Aquatic Toxicity: Toxic to aquatic life, may cause long-term harm in the environment
Bioaccumulation: Not expected to bioaccumulate significantly as bound to polymer
Mobility in Soil: Low mobility; undispersed masterbatch unlikely to migrate
Persistence and Degradation: Polymer carrier highly resistant to biodegradation, red phosphorus persists
Water Hazard Class: WGK 2 (hazard to water) per German regulations
Other Hazards: Do not allow to enter sewers or waterways; high phosphorus concentrations damage plant and animal life
Waste Disposal: Treat as hazardous chemical waste, consult licensed hazardous waste disposal contractor
Packaging: Triple rinse empty containers before disposal, destroy to prevent reuse
Disposal Methods: Incinerate only in permitted facility with proper emission controls, landfill as hazardous waste by local rules
