Product Name: White Phosphorus
Other Name: Yellow Phosphorus
Chemical Formula: P4
Appearance: Waxy, translucent, whitish-yellow solid, distinct garlic-like odor
Common Uses: Munitions manufacturing, incendiary devices, smoke screens, certain pesticide production
Physical Form: Solid turning yellow with slight impurities over time in air
CAS Number: 7723-14-0
Odor Threshold: Easily detectable pungency
Acute Risk: Extreme poison by ingestion, inhalation, or skin absorption
Chronic Risk: Bone damage, dental/jaw necrosis from long-term or repeated exposure
Fire Risk: Highly flammable in air, ignites spontaneously near room temperature
Explosion Potential: Burns fiercely with release of toxic fumes
Impact on Health: Severe burns, liver/kidney damage, central nervous effects
Chemical Danger: Strong reducing agent, reacts with atmospheric oxygen, incompatible with many oxidizers and strong bases
Label Pictograms: Skull and crossbones, flame, exclamation mark
Carcinogenicity: Evidence links inhalation to certain soft tissue cancers in industrial settings
Main Component: Elemental phosphorus, over 99% purity by weight
Impurities: Red phosphorus (trace), minimal organic contaminants
Hazardous Additives: None under standard industrial grades
Physical Structure: Exists as tetrahedral molecules, P4
Melting Point: 44°C, transitions rapidly to vapor at higher temperatures
Skin Contact: Remove contaminated clothing, douse with cool water, keep area moist, cover burns with wet lint, urgent hospital transfer
Eye Contact: Immediate and substantial flushing with water for 15 minutes, eyelids held apart, emergency attention required
Inhalation: Remove to fresh air, monitor for breathing difficulty, oxygen administered by professionals, urgent medical support
Ingestion: Forceful rinsing of mouth, do not induce vomiting, activated charcoal if conscious, seek immediate hospital care
Burns: Phosphorus particles may ignite with oxygen; oxygen exclusion methods sometimes used in hospital
Suitable Extinguishing Media: Flood with water to cool and isolate material
Unsuitable Extinguishing Media: Carbon dioxide, dry chemicals; do not use sand or dry powder
Hazards From Combustion: Liberates dense white smoke of phosphorus pentoxide, corrosive, respiratory hazard
Specific Precautions: Adjust the approach for wind direction to avoid exposure to fumes
Protective Equipment: Full body chemical protection with self-contained breathing apparatus
Special Measures: Containers at risk should be cooled with water from a safe distance
Personal Precautions: Evacuate area, restrict entry, full chemical suit including gloves and boots
Containment: Douse with cold water to stop ignition; collect fragments underwater
Cleanup: Scoop up material and transfer using specialized equipment, submerge in water for storage before disposal
Environmental Risks: Highly toxic to aquatic systems, avoid discharge to sewers and waterways
Spill Reporting: Prompt communication with local environmental authorities
Handling: Strict no-open-flame policy, splash shields, handling only in water or inert atmosphere
Workspaces: Forced ventilation, closed system handling preferred, robust contamination controls
Storage: Submerged under water or inert oil to prevent contact with air, locked cabinets, separate from oxidizers
Temperature Control: Store cool, maintain far from heat and light sources
Segregation: No contact with strong alkalis, oxidizers, halogens
Maintenance: Regular inspection for leaks, corrosion, or compromised containers
Occupational Exposure Limits: ACGIH TLV: 0.1 mg/m3 (as phosphorus)
Engineering Controls: Local exhaust and fully enclosed handling booths; monitor air regularly
Personal Protection: Impermeable gloves, chemical splash goggles, face shield, full-body suit
Respirators: Supplied-air respirators or self-contained breathing for high-risk exposure
Hygiene Practices: No eating, drinking, or smoking in handling areas, immediate washing facilities
State: Waxy solid, soft at room temperature
Density: Roughly 1.82 g/cm3
Solubility: Insoluble in water, soluble in carbon disulfide, slightly in oils
Melting Point: 44°C
Boiling Point: 280°C (decomposes)
Vapor Pressure: Significant above 20°C
Odor: Characteristic, garlic-like
Color: White to yellow, grows yellowish on air exposure
Reactivity: Immediate reaction with oxygen, oxidizers, halogens
Stability Under Storage: Stable only under water or inert oil
Polymerization: Not a concern in standard use
Hazardous Decomposition: Phosphine and phosphorus oxides on combustion; involved in fire situations
Material Incompatibilities: Alkalis, oxidizers, many metals
Acute Toxicity: Oral LD50 as low as 1 mg/kg in humans (rapid onset, high fatality)
Short-Term Effects: Severe burns, multi-organ failure, strong gastrointestinal symptoms
Long-Term Effects: Jaw necrosis (phossy jaw), anemia, marrow suppression
Routes of Exposure: Inhalation, skin absorption, accidental ingestion
Cancer Reports: Some evidence from worker studies, though not conclusive for the general population
Symptoms: Vomiting, diarrhea, chest pain, systemic toxicity with even brief exposure
Hazard To Aquatic Life: Persists in water, highly toxic to fish, aquatic invertebrates
Persistence: Low biodegradability, accumulates in sediments
Bioaccumulation: Observed in fish exposed to contaminated water
Impact: Small releases can devastate downstream ecosystems, oxygen depletion, fish kills
Soil Impact: Tends to volatilize but poses lingering risk in moist or marshy ground
Procedures: Gather residue, keep wet, transfer to secure hazardous waste storage, never landfill
Incineration: Only in controlled, licensed hazardous waste facilities with scrubbers
Environmental Caution: Prohibit release to water courses, drains, or soil
Container Management: Triple-wash, puncture-proof, processed as hazardous waste
Legal Requirements: Compliance with local, national, and international hazardous material disposal laws
Classification: Dangerous goods, UN 1381
Shipping Name: Phosphorus, white or yellow, under water
Packaging: Submerged in water or oil, sealed containers
Labeling: Poison, flammable solid, marine pollutant
Supply Chain Risks: Accidents lead to fire, water contamination, or toxic vapor clouds
Transport Mode: Ground, sea, or air under strict control, escorted shipments in many jurisdictions
Occupational Health: Strict workplace exposure limits, required hazard communication training
Environmental Law: Listed under hazardous air, water, and chemical release statutes; subject to CERCLA, RCRA in the USA
Global Registration: Notified under REACH in the EU, Schedule 3 of the Chemical Weapons Convention
Manufacture and Use: Many countries restrict end uses and mandate record-keeping
Incident Reporting: Mandated for substantial spills or accidental exposures under regional and national law
