Eye Contact: Immediately flush with gentle stream of water for at least 15 minutes, remove contact lenses if present, seek medical help if irritation persists.
Skin Contact: Remove contaminated clothing, rinse exposed skin with plenty of water, clean gently with soap, consult medical personnel for persistent redness or pain.
Ingestion: Rinse mouth, do not induce vomiting, drink water if patient is conscious, seek medical attention without delay; risk of chemical burns or respiratory issues
Inhalation: Move to fresh air, keep at rest, obtain medical attention if symptomatic; respiratory irritation, dizziness, and headache can occur in poorly ventilated areas
Suitable Extinguishing Media: Water spray (fog), large volumes of water, dry chemical powder, foam
Unsuitable Media: Do not use CO2 or halogenated extinguishing agents
Hazards: Organic peroxide accelerates burning, releases toxic vapors such as carbon monoxide, carbon dioxide, and possible hydrocarbons when decomposing
Protective Equipment: Fire-resistant suit, positive pressure self-contained breathing apparatus, chemical resistant gloves and boots
Firefighting Instructions: Cool storage drums or containers exposed to fire with water, avoid breathing fumes, remove personnel from danger zone, keep away from confined spaces
Spill Response: Isolate area, evacuate unnecessary people, avoid contact with oxidizable materials, eliminate ignition sources
Containment: Use non-combustible absorbent like sand or soil, shovel into chemical waste drums, prevent entry to sewers or waterways
Clean-up Methods: Use non-sparking, corrosion-resistant tools, ventilate area, collect residues with care, wash affected area with large amounts of water
Personal Protection: Wear full chemical resistant clothing, goggles, face shield, and chemical resistant gloves; NO open flames or smoking
Handling: Avoid rough handling, shock, and friction, never use near heat sources or smoking areas, keep containers tightly closed, do not return unused material to original container
Hygiene Practices: Wash hands before breaks and after finishing task, avoid eating, drinking, or smoking while using product
Storage: Store in cool, well-ventilated, and dry area, keep away from direct sunlight and incompatible chemicals such as strong acids, alkalis, reducing agents, combustible materials
Packaging: Store only in original, approved packaging equipped with safety release vents
Engineering Controls: Use only in areas with strong local extraction and general ventilation, monitor air for organic peroxide vapor levels
Personal Protection: Safety goggles, chemical-resistant gloves (nitrile, neoprene recommended), full sleeve protective apparel, face shield for splash risk
Respiratory Protection: Suitable NIOSH/MSHA-approved organic vapor respirator if airborne concentrations exceed limits
Exposure Limits: No established OSHA PEL or ACGIH TLV for TBPIN; minimize exposure as a precaution
Environmental Controls: Industrial effluent must be filtered or treated, avoid unintentional release into drains, surface or groundwater
Appearance: Clear to pale yellow oily liquid
Odor: Slight, hydrocarbon-like
Odor Threshold: Not established
pH: Not applicable
Melting Point/Freezing Point: Below -10°C
Boiling Point: Decomposes above 130°C

Relative Density: 1.02 (Water = 1)
Solubility in Water: Insoluble
Partition Coefficient (Log Kow): Not determined
Auto-ignition Temperature: >200°C
Decomposition Temperature: 130°C
Explosive Properties: Strong oxidizer
Chemical Stability: Stable at recommended storage temperature, sensitive to heat, friction, mechanical shock
Incompatible Materials: Strong reducing agents, acids, bases, heavy metal compounds, amines, combustibles
Hazardous Decomposition: Releases carbon monoxide, carbon dioxide, hydrocarbons, and possibly phenolic compounds upon burning or decomposition
Polymerization: No dangerous polymerization expected under recommended storage and use conditions
Acute Effects: Eye and skin irritation, inhalation may cause coughing, nausea, and headache, ingestion triggers abdominal discomfort
Chronic Effects: Prolonged, repeated contact increases risk of dermatitis and sensitization
LD50 (Oral, Rat): 1,570 mg/kg for active component
LD50 (Dermal, Rabbit): 2,430 mg/kg for active component
LC50 (Inhalation, Rat): Not determined
Carcinogenicity: Not classified as carcinogenic by IARC, NTP, or OSHA
Additional Risks: Data shortfalls in reproductive, mutagenicity, and developmental toxicity
Aquatic Toxicity: Toxic to fish, Daphnia, and algae; median effect concentrations (EC50) typically between 1.2-6.5 mg/L for aquatic invertebrates
Persistence and Degradability: Biodegrades over extended periods, not classified as readily biodegradable
Bioaccumulation Potential: Moderate based on hydrophobic character
Mobility in Soil: Tends to bind strongly to organic matter, low risk of leaching into water tables
Other Effects: Spills may cause fish die-offs, negative effect on aquatic plants if release is large
Waste Handling: Treat as hazardous organic peroxide waste, must deactivate prior to disposal
Disposal Methods: Cautiously dilute with inert, non-flammable solvent and neutralize under controlled conditions, contact specialized hazardous waste facility
Packaging Disposal: Triple rinse, puncture empty containers, send for incineration or approved landfill
Regulatory Notes: Never dispose of down the drain or in regular municipal waste streams, consult local regulations for restrictions
