Eye Contact: Rinse thoroughly with clean water for several minutes, hold eyelids open, remove contact lenses. Get medical attention if irritation persists.
Skin Contact: Wash skin with soap and water. Remove contaminated clothing. Use skin cream for dryness. Seek help for persistent redness.
Inhalation: Move to fresh air. Supply oxygen if breathing is difficult. Get medical support if coughing or wheezing continues.
Ingestion: Rinse mouth. Do not induce vomiting. Get prompt medical advice.
Suitable Extinguishing Agents: Dry sand, dry powder, carbon dioxide. Avoid water or foam due to phosphorus’s water-reactivity potential.
Special Hazards: Phosphorus fumes (phosphoric oxides) can form in fire. Hot vapors and dense smoke impair breathing.
Advice for Firefighters: Wear full protective gear and SCBA. Cool containers with water from safe distance. Remove product from fire area if possible.
Explosion Data: Keep away from strong oxidizers and heat sources to prevent runaway reactions.
Personal Precautions: Evacuate unprotected personnel, ventilate area, avoid dust creation. Wear gloves, goggles, mask, and protective clothes.
Spill Cleanup: Gently scoop up material without raising dust, place in dry, labeled containers. Use antistatic tools. Avoid contact with sources of ignition.
Environmental Precautions: Prevent runoff into drains and waterways; red phosphorus is not water soluble but dust can cause local issues in big spills.
Disposal Methods: Collect for proper chemical waste disposal in line with local regulations.
Handling: Work in well-ventilated areas, use dust extraction if needed. Avoid friction, impact, and open flames. Do not eat or drink near product.
Safe Storage Conditions: Store in a cool, dry, well-ventilated room. Keep away from sunlight, strong oxidizers (such as peroxides, chlorine), strong acids, bases. Use secure, labeled containers with tight closures. Maintain segregation from incompatible substances.
Other Precautions: Ground all equipment, minimize static build-up. Restrict access to trained personnel.
Occupational Exposure Limits: Phosphorus TWA: 0.1 mg/m³ (OSHA, ACGIH)
Engineering Controls: Use local exhaust or general ventilation to keep dust below exposure limits.
Personal Protection: Eyes: Face shield or chemical safety goggles. Hands: Chemical-resistant gloves like nitrile. Skin: Overalls, long sleeves. Respiratory: Filtering mask (N95 or higher) for dust.
Hygiene Measures: Wash thoroughly after handling. No eating, drinking, smoking in work area.
Appearance: Reddish brown granular pellets
Odor: Faint, characteristic
Melting Point: Red phosphorus sublimes at around 416°C (not melts in traditional sense)
Boiling Point: Not applicable (decomposes before boiling)
Solubility in Water: Insoluble
Specific Gravity: 1.8–2.3 (depending on carrier resin)
Vapor Pressure: Not applicable
Flash Point: >300°C
Auto-Ignition Temperature: 300-350°C
Particle Size: Customized for masterbatch, typical range 2–5 mm
Other Data: Dust can ignite or explode in air above certain concentrations.
Chemical Stability: Stable under recommended storage conditions.
Reactivity: Strongly reacts with oxidizers, halogens, and some acids.
Conditions to Avoid: High temperatures, ignition sources, open flames, friction, static.
Incompatible Materials: Strong oxidizers (such as potassium nitrate, chlorates), strong acids.
Hazardous Decomposition Products: Phosphoric acid fumes, phosphine gas (in rare cases of decomposition).
Acute Toxicity: Low toxicity by ingestion due to polymer encapsulation, but pure red phosphorus is toxic (LD50 oral rat ~640 mg/kg).
Skin/Eye Irritation: Causes redness, irritation after prolonged or repeated contact.
Respiratory Effects: Inhalation of dust can lead to coughing, wheezing, possible lung irritation.
Chronic Exposure: Excessive repeated exposure may affect teeth, bones (phosphorus necrosis), rare with modern controls.
Carcinogenicity: Not classified as a human carcinogen by OSHA, IARC, NTP.
Sensitization: No confirmed data for skin or respiratory sensitization.
Environmental Behavior: Not water soluble, binds to soil. Pellets may persist in soil for extended periods.
Aquatic Toxicity: Low likelihood of acute toxicity to aquatic organisms in pellet form, dust contamination can harm aquatic life.
Bioaccumulation: Not expected due to polymer barrier; pure red phosphorus is not known to bioaccumulate.
Persistence: Slowly degrades under UV light and weathering.
Mobility: Limited; if spillage occurs, clean-up is best practice to prevent local issues.
Waste Treatment Methods: Treat as hazardous chemical waste. Incinerate or landfill following local environmental authority guidance.
Disposal of Containers: Triple rinse empty containers before recycling or landfill. Do not reuse for other substances.
Avoid Release: Prevent product from entering natural water systems, drains, or soil.
Regulations: Dispose only through licensed chemical waste handlers.
