Substance name: Di-Tert-Butyl Peroxide mixed with Type B diluent
Form: Liquid, usually colorless or pale yellow
Common uses: Polymerization initiator, industrial chemical processes
Concentration: Active ingredient capped at 52%, blended to at least 48% with a diluent labeled Type B
Recognized by: Distinct characteristic odor, often compared to ether or similar solvents
Handling group: Organic peroxide mixture, regulated as hazardous by most global transport and storage standards
Main risks: Flammable, can ignite from heat, sparks, or open flame
Health concerns: Causes irritation to eyes, skin, and respiratory tract; possible release of flammable or toxic gases if heated or involved in fire
Environmental hazard: Dangerous to aquatic life by disrupting oxygen balance in waterways
GHS pictograms: Flame, exclamation mark, environment
Immediate effects: Exposure brings stinging or burning sensations, dizziness or drowsiness from inhalation of vapors
Chronic risks: Long-term exposure potentially linked to central nervous system effects and possibly organ toxicity
Active chemical: Di-Tert-Butyl Peroxide (percentage limited to half of total volume or less)
Diluent base: Type B diluent forming the balance of the blend
Percents: Peroxide ≤52%, Diluent ≥48% (usually a specific hydrocarbon solvent)
Impurities: Minor byproducts from synthesis can pose their own hazards, typically monitored during quality control to keep below thresholds affecting stability or safety
Inhalation: Move person to fresh air, keep warm and rested, monitor breathing, seek medical advice if symptoms judged severe or persistent
Skin contact: Rinse affected area with soap and water, remove contaminated clothing, watch for irritation or burns
Eye contact: Rinse with copious clean water for at least fifteen minutes, do not allow user to rub the eyes
Ingestion: Rinse mouth out, do not induce vomiting, see a physician immediately
Key advice: Medical professionals should have background on symptoms pointing to peroxide exposure—oxygen therapy may help respiratory distress
Suitable extinguishing media: CO2, dry chemical powder, foam, avoid water spray directly on blazing material due to risk of peroxide decomposition
Fire hazards: Explosively decomposes at high temperature, emitting flammable gases and dense smoke
Thermal decomposition: Unstable above 50°C, reacts violently with strong reducing agents or acids
Protective gear: Fire fighters require self-contained breathing apparatus and full protective gear up to chemical flash suit level
Evacuation: Surrounding area should be cleared given the extended risk of secondary explosions from storage tanks or spilled liquid
Protective actions: Remove all ignition sources, stop the leak if safe to do so, isolate the area
Spill control: Absorb spillage using inert materials like vermiculite or sand, transfer to a safe, labeled waste container
Cleanup workers: Minimum, wear gloves, goggles, and chemical resistant boots; avoid skin and eye contact strictly
Environmental steps: Prevent runoff into drains, surface waters, or soil; containment booms used if accident occurs near water
Ventilation: Open up doors and windows for ventilation—vapor builds up quickly and can accumulate in low zones posing explosion risk
General precautions: Keep container tightly closed, avoid impact or friction, handle with non-sparking tools
Storage requirements: Cool, well-ventilated, shaded area away from incompatible materials like acids, alkalis, and oxidizers
Segregation: Store separately from food, feedstuffs, clothing, and living quarters
Temperature limits: Keep below recommended maximum (typically 30°C), sudden changes or extreme highs undermine chemical stability fast
Storage vessel: Use containers made from stainless steel or high-density polyethylene; inspect for deterioration periodically
Transfer tips: Ground and bond all containers to prevent static discharge, avoid overfilling
Ventilation: Use fume hoods or exhaust fans in areas of regular handling
Exposure limits: No authoritative occupational limit set, but keep personal exposure as low as possible due to toxicity
Personal Protection: Gloves made of neoprene or nitrile, chemical splash goggles or face shield, flame-retardant clothing, and respiratory protection when ventilation can’t match vapor levels
Hygiene: Remove contaminated workwear and wash skin thoroughly after use, do not eat, drink, or smoke around product
Emergency equipment: Eye wash stations and safety showers need to stay ready near handling zones
Form: Liquid
Color: Clear to pale yellow
Odor: Pungent, reminiscent of ether
Boiling point: Approximately 110–112°C
Melting point: -40°C or below
Vapor pressure: Moderate at room temperature, rises sharply in warmth
Solubility: Insoluble in water, miscible with organic solvents
Flash point: Around 10°C for these mixtures
Stability: Unstable at higher temperatures or in presence of contamination
Vapor density: Heavier than air, collects in low spots increasing inhalation and explosion risk
Chemical stability: Stable at low temperatures, vulnerable to self-accelerating decomposition near or above 50°C
Incompatible substances: Strong acids, bases, reducing agents, and some metals such as copper or brass trigger violent reaction
Hazardous decomposition: Raises danger of carbon monoxide, carbon dioxide, tert-butyl alcohol and flammable hydrocarbons
Risk points: Small leaks or spills warm up quickly, meaning loss of containment can lead to sudden fire or explosion
Sensitivities: Sensitive to light, heat, static discharge, and friction inside pipes or containers
Acute exposure: High doses may cause confusion, headaches, nausea, loss of coordination, central nervous system effects
Routes: Inhalation, skin and eye contact are main risks
Corrosivity: Irritating but not typically corrosive to skin, more severe if concentrated
Absorption: Readily absorbed through the skin, more hazard by inhaling concentrated vapors
Chronic exposure: No confirmed carcinogenicity, but repeated exposures have aggravated dermatitis and respiratory conditions in industrial settings
Symptoms: Watery or stinging eyes, breathing difficulty, recurring headaches in under-ventilated spaces
Bioaccumulation: Unlikely due to volatility and rapid breakdown in environment, but breakdown products may still affect soil and water organisms
Aquatic life: Toxic to fish and micro-organisms; leaks or effluent limit water usability and disrupt ecosystems fast
Soil mobility: Moves rapidly with spilled liquid, contaminating wide area
Degradability: Breaks down in sunlight and air but leaves persistent byproducts unless fully decomposed
Precaution: Never flush down drains, practice tight leak control near storm water inlets or marshy zones
Waste method: Incinerate in a licensed facility; do not landfill, do not pour out
Handling: Keep waste cool and sealed until destruction
Contaminated packaging: Rinse cautiously if permitted, otherwise treat as hazardous for incineration
Legal compliance: Follow local environmental protection rules; never allow unauthorized parties to handle disposal
Safety monitoring: Track all disposal from generation to final destination as part of compliance with environmental audits
Classification: Organic peroxide Type E, regulated by global hazardous materials guidelines
Proper shipping name: Organic peroxide mixture, viscous, Type E
Packing group: Often II, as a moderate hazard
Labeling: Flammable and reactive hazard indicators visible on containers and vehicles
Storage in transit: Away from food, heat sources, and public zones; maintain steady temperature during unloading
Emergency plan: Escort by personnel trained in hazardous materials response on longer journeys
Workplace safety: Covered by OSHA regulations in the workplace, with standards for chemical hazards, use of PPE, exposure limits and emergency response
Environmental control: Regulations limit emissions, spills, and require programs to prevent contamination
International transport: Subject to UN Recommendations on Transportation of Dangerous Goods, IMDG Code for shipping, and ADR/RID for rail/road carriage
Community disclosure: Inclusion in local hazardous chemical inventories, right-to-know programs, and emergency planning systems
Periodic review: Safety protocols and hazard assessments updated as technology advances and regulatory frameworks shift in response to new science
