Substance: Lead Tetrafluoride
Chemical Formula: PbF4
CAS Number: 7783-59-7
Concentration: 100%
Impurities: Trace heavy metals and other fluorides may be present depending on synthesis
Molecular Weight: 283.2 g/mol
Typical Appearance: Pale yellow crystalline solid
Inhalation: Remove victim to fresh air, keep warm and quiet. Call emergency services. If breathing stops, give artificial respiration using pocket mask or bag-valve mask. Oxygen by qualified personnel.
Skin Contact: Immediately flush with copious amounts of lukewarm running water for at least 20 minutes. Remove contaminated clothing. Apply calcium gluconate gel for hydrofluoric acid burns if available. Seek immediate medical attention.
Eye Contact: Rinse eyes under gentle running water for a minimum of 15 minutes. Hold eyelids open. Remove contact lenses if present. Continue irrigation and seek urgent medical treatment.
Ingestion: Do not induce vomiting. Rinse mouth with water if the victim is conscious. Never provide anything orally if unconscious. Seek medical attention immediately. Transport patient with material safety data.
Suitable Extinguishing Media: Dry sand, dry chemical, carbon dioxide. Water not effective on fire, but can be used carefully for cooling sealed containers.
Unsuitable Media: Water jets—can produce corrosive hydrofluoric acid gas
Hazards from Combustion: Toxic, corrosive vapors of hydrogen fluoride and lead compounds; risk of fume inhalation.
Protective Equipment: Full protective suit, positive pressure self-contained breathing apparatus (SCBA). Avoid skin and eye contact, avoid inhalation of dust and fumes.
Firefighting Instructions: Evacuate area and fight fire from safe distance. Cool containers with flooding quantities of water from protected position if exposed to fire. Avoid runoff contamination.
Personal Precautions: Full protective gear—chemical-resistant gloves, safety goggles, face shield, lab smock or chemical suit. Provide adequate ventilation. Remove unprotected personnel.
Environmental Precautions: Prevent entry into waterways, drains, or soil. Notify authorities in case of environmental contamination.
Clean-up Methods: Avoid raising dust. Use non-sparking tools to scoop solid spills into secure, labeled containers for disposal. Decontaminate area with calcium carbonate or soda ash solution if permitted. Collect and treat wash residues properly. Follow up with extensive washing.
Safe Handling: Work only in fume hood or well-ventilated, designated area. Do not breathe dust, fumes, or vapors. Avoid contact with skin, eyes, and clothing. No food, drink, or smoking where material handled. Monitor air levels regularly. Loosely cap containers to avoid pressure.
Storage: Store in tightly closed, corrosion-resistant containers. Keep in cool, dry, well-ventilated location separated from acids, organics, and combu stibles. Use secondary containment. Clear hazard signage. Secure from unauthorized personnel.
Control Parameters: OSHA PEL for lead: 0.05 mg/m³ TWA; ACGIH TLV: 0.05 mg/m³. No established limit for tetrafluoride ions; consult state/local regulation.
Engineering Controls: Use certified chemical fume hood. Local exhaust recommended. Enclosed processes where feasible.
Personal Protective Equipment: Chemical-resistant gloves (e.g., nitrile, neoprene), lab coat or Tyvek suit, full-face shield with safety goggles, properly fitted respiratory protection for particulates and vapors, such as NIOSH-approved half-mask/ full-face respirators for dust or SCBA for emergencies.
Appearance: Pale yellow, crystalline solid
Odor: Odorless
Boiling Point: Decomposes, does not boil
Melting Point: Approximately 600°C
Solubility: Reacts with water, hydrolyzes
Density: 9.53 g/cm³
Vapor Pressure: Not applicable
pH: Not applicable
Evaporation Rate: Not volatile
Partition Coefficient (n-octanol/water): Not established
Flash Point: Not flammable
Other: Highly reactive with acids and reducing agents, emits toxic gases on decomposition
Chemical Stability: Unstable in moist air, decomposes on exposure to water or humidity, liberates toxic fluorine and lead compounds on thermal decomposition
Conditions to Avoid: Heat, moisture, direct sunlight
Materials to Avoid: Water, acids, strong bases, oxidizable and combustible substances, organic materials, ammonia, alkali metals
Hazardous Decomposition: Hydrogen fluoride, lead oxides, lead fluorides, fluorine gas
Polymerization: Will not occur
Likely Routes of Exposure: Inhalation, dermal contact, ingestion, eye exposure
Acute Effects: Highly toxic if inhaled, ingested, or absorbed through skin. Severe local and systemic toxicity: can cause severe burns, respiratory distress, gastrointestinal damage, acute lead poisoning symptoms (abdominal pain, headache, nausea).
Chronic Effects: May lead to neurological, kidney, reproductive, and developmental disorders from cumulative lead exposure. Chronic fluorosis with bone and dental changes.
Carcinogenicity: Lead compounds are classified by IARC as 2A (probably carcinogenic to humans).
Additional Data: Central nervous system and kidney effects possible at low doses; hazardous to unborn child by crossing placental barrier.
Toxicity to Aquatic Life: Highly toxic to aquatic organisms. Bioaccumulates in organisms and sediments.
Persistence/Degradability: Lead persists and accumulates in environment, poor biodegradability.
Mobility: Lead ions strongly adsorb to soil; fluorides may migrate through groundwater, causing long-term hazards.
Other Environmental Hazards: May cause genetic defects in wildlife, harm reproductive cycles, contaminate drinking water sources.
Waste Treatment Methods: Dispose of in accordance with national and local hazardous waste regulations. Handle as toxic heavy metal waste.
Product Disposal: Small amounts neutralized with specific agents under fume hood by trained personnel. Container and residue must be treated as hazardous waste.
Contaminated Containers: Triple rinse, then dispose through licensed hazardous waste handler. Never reuse empty containers.
Precautions: Never allow to reach sewage system or environmental water bodies.
