Precautionary Statements: Avoid breathing dust, wear protective gloves and eye protection, do not eat, drink or smoke while handling product, avoid release into the environment
Other Hazards: Fine dust forms explosive mixtures with air, moisture sensitive
Chemical Name: Red Phosphorus
CAS Number: 7723-14-0
Concentration: 90–100%
Impurities: May include minor amounts of yellow or white phosphorus, trace heavy metal salts
Additional Additives: Some commercial preparations blend with stabilizers or dispersing agents (usually below 5% concentration)
General Advice: Move exposed person to fresh air, avoid breathing in dust during rescue, seek medical attention if serious symptoms develop
Inhalation: Remove to fresh air, monitor for cough or respiratory difficulty; give oxygen if breathing trouble persists, seek immediate medical assistance
Skin Contact: Remove contaminated clothing, wash area thoroughly with water and mild soap, do not scrub, seek medical attention if irritation remains
Eye Contact: Flush eyes gently for at least 15 minutes with plenty of water, hold eyelids apart, remove contact lenses if present and easy to do, consult medical professional promptly
Ingestion: Rinse mouth, never give anything by mouth if unconscious, do not induce vomiting, seek immediate medical help due to high toxicity risk
Extinguishing Media: Use dry sand, dry powder fire extinguishers, or Class D extinguishing agents only; water, foam, and CO2 are not suitable
Specific Hazards: Reacts violently with oxidizers, emits toxic phosphorus oxides and possible phosphine gas on burning
Protective Gear: Full protective clothing and self-contained breathing apparatus for all responders due to toxic gas release
Special Procedures: Remove product from vicinity if not involved in fire when safe to do so, avoid direct water spray; cool surroundings with water spray from a distance to minimize heating of containers
Personal Precautions: Isolate area, evacuate unnecessary personnel, ventilate enclosed spaces, avoid dust formation
Protective Equipment: Use suitable respiratory protection, chemical-resistant gloves, goggles, and antistatic clothing
Environmental Precautions: Prevent product from entering drains, waterways, or soil
Cleanup Methods: Collect spill with spark-proof tools into inert container for disposal, avoid dry sweeping (use damp methods if necessary and safe), ensure dust is not dispersed in air, decontaminate site with approved phosphorus neutralizers
Safe Handling: Handle only in well-ventilated facilities, keep away from heat, sparks, sources of ignition, and incompatible materials such as oxidizers, acids, or halogens, use only non-sparking tools, ground all equipment
Hygiene Procedures: Wash hands before eating, avoid skin contact, don’t touch face or eyes during handling, keep work area free from dust build-up
Storage Conditions: Store in tightly closed containers, keep in a cool, dry, well-ventilated place, use explosion-proof lighting and electrical installations, segregate from food, feed, and oxidizers, monitor storage area temperature to avoid overheating
Exposure Limits: OSHA PEL: 0.1 mg/m3 (as phosphorus), NIOSH REL: 0.1 mg/m3
Engineering Controls: Use local exhaust ventilation to control dust, employ process enclosures where feasible, regularly monitor airborne concentration
Respiratory Protection: Wear approved particulate respirator (P3 or N100 type) during dusty operations
Hand Protection: Chemical-resistant gloves such as nitrile or neoprene
Eye Protection: Chemical splash goggles or face shield, particularly during mixing or transfer
Skin Protection: Long-sleeved antistatic clothing, suitable protective footwear
Other Protective Measures: Emergency wash stations and eye baths stationed in work zone
Appearance: Dark red, violet or brownish powder/granules
Odor: Odorless
pH: Not applicable (insoluble in water)
Melting Point: Sublimation above 416°C (no true melting point under atmospheric pressure)
Relative Density: 2.31–2.34 (water=1)
Solubility: Insoluble in water and ethanol; soluble in concentrated alkalis,
Vapor Pressure: Practically zero at room temperature
Boiling Point: Not applicable
Flash Point: 300°C (572°F)
Auto-Ignition Temperature: 260–300°C (depends on dust size, dispersion)
Partition Coefficient: Not determined for elemental phosphorus
Evaporation Rate: Not relevant
Chemical Stability: Stable at room temperature in closed containers, sensitive to friction, heat or prolonged sunlight
Reactivity: Reactive with strong oxidizing agents, halogens, acids, peroxides, can form phosphine gas with alkalis
Conditions to Avoid: Avoid high temperatures, open flame, shock, static discharge, sources of strong UV light
Hazardous Decomposition: Toxic phosphorus oxides (P2O5), phosphine gas under reducing conditions
Polymerization: Will not polymerize spontaneously, but product reacts violently with strong oxidizers
Acute Toxicity: LD50 oral (rat): 50 mg/kg; inhalation toxic at unconfirmed but assumed low levels; skin not readily absorbed; severe irritation possible
Skin Corrosion/Irritation: Causes redness, pain, may cause ulceration after repeated exposure
Eye Damage/Irritation: Dust can cause serious eye irritation or damage
Respiratory Sensitization: Dust inhalation may cause coughing, sneezing, possible lung irritation
Chronic Effects: Prolonged exposure can impact liver and kidney function, risk of "phossy jaw" in severe, long-term contact cases
Carcinogenicity/Mutagenicity: Not proven for red phosphorus, but long-term exposures not fully studied
Aquatic Toxicity: Red phosphorus is highly toxic for most aquatic organisms; bioaccumulation possible
Persistence and Degradability: Not readily biodegradable, persistent in soils and sediments
Mobility: Insoluble, unlikely to migrate in natural waters, may settle or bind to particulates
Ecotoxic Effects: Large releases harm fish and invertebrates, disrupt aquatic ecosystems, converts to harmful phosphates
Additional Considerations: Spills near wetlands or riverbanks create lasting contamination; slow downstream transport via sediment binding
Product Disposal: Classified as hazardous waste under most regulations; incinerate only in chemical incinerators with afterburner and scrubber, consult regional or national hazardous waste agency
Container Disposal: Triple-rinse, puncture, render unusable, dispose at hazardous waste facility
Precautions: Never dispose with general waste, avoid landfill contamination, do not release into sewers or watercourses
Other Methods: Small quantities may be deactivated using certified methods under careful supervision by environmental handler
