Manufacturer: Supplier details based on local regulations, typically industrial chemical distributor
Emergency Contact: Refer to national poison control centers, local fire department, or specific company’s 24-hour response line
Classification: Acute toxicity, Reproductive toxicity, Specific target organ toxicity—repeated exposure
GHS Label Elements: Skull and crossbones, Health hazard icons
Signal Word: Danger
Hazard Statements: Toxic if swallowed, causes damage to organs through prolonged or repeated exposure, suspected of damaging fertility or the unborn child
Precautionary Statements: Do not breathe dust, avoid contact with skin and eyes, wash hands thoroughly after handling, use personal protective equipment as required
Chemical Name: Trilead Tetroxide
Common Synonyms: Red Lead
Concentration: Greater than 99% purity
Impurities: Trace amounts of PbO (Lead Oxide), trace silica or mineral matter from production processes
Inhalation: Move person to fresh air, keep comfortable for breathing, seek medical advice if symptoms persist such as headache, nausea, or shortness of breath
Skin Contact: Remove contaminated clothing, wash skin thoroughly with water and soap, seek medical attention for prolonged irritation
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing, obtain medical attention for persistent redness or irritation
Ingestion: Rinse mouth with water, do not induce vomiting, seek medical care immediately, be prepared to provide information on exposure amount and time
Suitable Extinguishing Media: Use dry chemical, foam, sand, or carbon dioxide; avoid water jets which may spread dust
Special Hazards: Heating above decomposition temperatures releases toxic lead fumes and oxides
Protective Equipment: Firefighters need self-contained breathing apparatus and full protective clothing to prevent lead dust inhalation and exposure to hot decomposition products
Specific Tactics: Prevent runoff of water or chemicals from entering sewers or water sources to limit release of contamination
Personal Precautions: Wear respiratory protection, chemical-resistant gloves, protective clothing, and safety goggles
Environmental Precautions: Stop discharge and prevent material from spreading into water bodies, soil, or drains; communicate hazard to all personnel in the area
Cleanup Methods: Sweep up without generating dust, shovel into suitable, sealed containers for disposal, use damp cloths or HEPA-filtered vacuums for residue, ventilate area after cleanup
Handling: Use in well-ventilated areas, avoid inhaling dust and contact with skin, maintain strict hygiene practices, never eat or smoke in work area, use specialized containers and instruments
Storage Conditions: Store in tightly closed containers in a cool, dry, and well-ventilated place away from acids, strong oxidizers, and incompatible materials, limit access to authorized personnel, provide secure labeling
Incompatibilities: Reacts with acids to release toxic gases, incompatible with strong reducing agents, avoid strong oxidizers that can generate exothermic reactions
Exposure Limits: Occupational exposure limits vary by region; OSHA PEL = 0.05 mg/m3 (as Pb), ACGIH TLV = 0.05 mg/m3 (as Pb)
Engineering Controls: Use local exhaust ventilation, enclosed handling systems, regular air monitoring, and negative pressure rooms if high quantities are processed
Personal Protective Equipment: NIOSH-approved respirators for particulates, chemical-resistant gloves (nitrile, neoprene), full-body coveralls, and safety goggles
Hygiene Measures: Provide facility for hand and face washing, change clothes after use, avoid taking contaminated clothing home, routine blood lead monitoring for long-term workers
Appearance: Heavy, red-orange powder
Odor: Odorless
Melting Point: Around 500°C (decomposes above this temperature)
Solubility: Insoluble in water, soluble in acids
Vapor Pressure: Negligible at standard temperatures
Density: About 9.1 g/cm3
pH: Neutral to slightly basic (suspension in water)
Boiling Point: Not applicable (decomposes at high temperature)
Explosive Properties: Not explosive, does not form explosive dust/air mixtures
Chemical Stability: Stable at ambient temperatures and pressures in sealed containers
Hazardous Reactions: Reacts with acids to form toxic lead compounds and gases, reacts with strong reducing agents
Decomposition Products: Lead oxides, toxic vapors when heated strongly
Conditions to Avoid: Heat, moisture, acids, strong reducing or oxidizing agents, physical damage to containers
Acute Effects: Ingestion or inhalation rapidly affects gastrointestinal, nervous, and circulatory systems causing symptoms like abdominal pain, headache, irritability, and in severe cases, seizures or anemia
Chronic Effects: Regular contact and accumulation can cause kidney damage, reproductive and developmental toxicity, nerve system damage, memory loss, and fatigue
Sensitization: Rare, but skin contact may produce irritation in some workers
Carcinogenicity: Classified as a possible human carcinogen (IARC Group 2A)
Mutagenicity: Evidence shows chromosomal and DNA damage with chronic exposure
Routes of Entry: Inhalation, ingestion, dermal absorption
Ecotoxicity: Highly toxic to aquatic life and soil organisms, persistent contamination leads to bioaccumulation in the food chain
Persistence and Degradability: Does not degrade, remains in soil and sediment for many years
Bioaccumulative Potential: Readily accumulates in fish, birds, and mammals, enters human food sources
Mobility in Soil: Primarily binds to sediments and particles; risk rises in acidic and moist soils
Other Adverse Effects: Long-term contamination affects crop yields, groundwater quality, and poses significant health concerns in communities relying on affected areas
Waste Handling: Contaminated material, containers, and dust collected during cleanup considered hazardous waste
Disposal Methods: Dispose of in accordance with local, state, or national regulations for lead-containing compounds; approved hazardous waste landfill facilities
Special Precautions: Do not discharge into sewers, water sources, or soil; incineration not suitable due to toxic metal release; document all handling and disposal steps clearly
