Impurities: May include trace stabilizers or decomposition inhibitors as per supplier specification
Inhalation: Move exposed individual to fresh air immediately; Maintain open airway; Administer oxygen if breathing is labored or irregular; Seek medical evaluation for respiratory symptoms
Skin Contact: Take off contaminated clothing; Rinse skin thoroughly with lukewarm water and non-abrasive soap for at least fifteen minutes; Seek medical attention for symptoms such as persistent redness or blistering
Eye Contact: Promptly rinse eyes with gentle stream of water for at least twenty minutes, lifting upper and lower lids; Remove hard contact lenses during rinsing if present and easy to do; Emergency examination by ophthalmologist is essential for persistent irritation
Ingestion: Rinse mouth; Never induce vomiting due to potential aspiration risk; Give plenty of water only if fully conscious; Consult emergency physician without delay
Notes for Physician: Monitor for respiratory distress, systemic effects associated with organic peroxide exposure, and treat symptomatically
Suitable Extinguishing Media: Large water spray, dry chemical, foam, carbon dioxide to suppress fire and cool surfaces
Unsuitable Extinguishing Media: Direct water jet may disperse burning product or cause spattering
Specific Hazards: Decomposition under heat releases flammable gases including carbon monoxide, carbon dioxide, and possibly other toxic fumes
Firefighting Procedures: Evacuate non-essential personnel; Wear positive-pressure, self-contained breathing apparatus and chemical-protective clothing; Isolate from oxidizers, acids, and accelerants; Use fire-resistant barriers
Explosion Risk: Heat or fire exposure can result in violent decomposition or explosion; Material may reignite after extinguishing if not adequately cooled
Personal Protection: Evacuate unnecessary personnel; Don chemical splash goggles, heavy-duty gloves, and flame-resistant clothing; Use positive-pressure respirator if dust or fumes present
Containment: Prevent entry into sewers, drains, or confined spaces; Block further spreading using inert absorbent (vermiculite, clay, sand) but never organic material such as sawdust
Clean-Up: Collect spilled material with non-sparking tools; Place residue into approved waste containers; Decontaminate spill area with large quantities of water, ensuring runoff is controlled
Environmental Precautions: Prevent direct discharge to ground, surface water, or storm drains; Notify regulatory authorities in the event of a substantial spill
Handling: Avoid shaking, impact, or friction; Use spark-free tools and explosion-proof equipment; Maintain strict segregation from reducing agents, acids, heavy metal salts; Use only with proper ventilation and never in areas subject to open flames or hot surfaces
Storage: Store refrigerated (2°C–8°C) in original, tightly closed containers designed for peroxides; Locate in detached or isolated building constructed with non-combustible materials; Limit inventory volume per fire regulations; Keep away from incompatible materials including oxidizers and combustibles; Post clear hazard labeling and access control signs
Special Notes: Frequent visual inspections and temperature checks reduce risks of decomposition and thermal runaway
Exposure Limits: No established occupational exposure limits for pure compounds, but minimize airborne concentrations based on hazard class
Engineering Controls: Use local exhaust ventilation at points where vapor or dust may form; Equip workspace with explosion-proof ventilation systems; Provide emergency eyewash and drench showers
Personal Protection: Full-coverage chemical-resistant gloves (nitrile, neoprene), safety goggles with face shield, impervious clothing, and flame-resistant lab coat; Respiratory protection (PAPR or air-line respirator) if vapor/dust/oxygen levels raise concern
Hygiene Practices: Wash hands thoroughly after use, particularly before eating, drinking, or smoking; Remove contaminated clothing before leaving work
Appearance: White or off-white free-flowing powder or moist granular solid
Odor: Mild, slightly sharp chemical odor
pH: Not applicable in dry solid state
Melting/Decomposition Point: Begins to decompose between 60°C and 100°C
Flash Point: Below 60°C (varies with formulation)
Auto-Ignition Temperature: Approximately 180°C
Vapor Pressure: Very low under standard conditions
Solubility: Insoluble in water; soluble in certain organic solvents such as hydrocarbons and esters
Density: 1.0–1.2 g/cm³ (bulk, varies with inert content)
Partition Coefficient (n-Octanol/water): Not available for mixture
Viscosity: Not applicable
Chemical Stability: Unstable when heated above recommended storage temperature
Conditions to Avoid: Heat, flame, spark, prolonged exposure to sunlight or elevated temperature, physical shock
Incompatible Materials: Acids, strong bases, amines, heavy metals, reducing agents, combustibles
Decomposition Products: Releases flammable gases such as carbon monoxide, carbon dioxide, and possibly irritating organic vapors
Hazardous Reactions: Rapid and violent exothermic decomposition possible, especially if contaminated or heated
Acute Toxicity: Ingestion or inhalation can lead to dizziness, nausea, headache, respiratory irritation, and, in severe cases, pulmonary edema or central nervous system depression
Chronic Toxicity: Skin and eye irritation remain concerns with continued exposure; No evidence supports chronic organ system toxicity under typical industrial handling
Sensitization: Prolonged skin contact may cause allergic reaction in rare cases
Carcinogenicity: No conclusive evidence exists for its listing as a carcinogen by globally recognized agencies (IARC, NTP, OSHA)
Mutagenicity: Available data does not provide evidence of genotoxic potential
Routes of Exposure: Primary through inhalation, skin, and eye contact
Other Effects: Individuals with existing respiratory or skin conditions face increased risk for aggravated effects
Ecotoxicity: Harmful to aquatic organisms due to oxidative stress and potential for organic peroxide degradation products
Persistence and Degradability: Not rapidly biodegradable; decomposition products may persist or accumulate in aquatic soil or sediments
Bioaccumulation: Low potential for bioaccumulation; high water insolubility limits spread in natural water bodies
Mobility: Insoluble and heavy particles settle in water, reducing movement
Additional Considerations: Prevent uncontrolled discharge or disposal to forests, surface waters, drains, or groundwater sources
Waste Disposal: Handle as hazardous waste under national chemical waste codes; Small laboratory or industrial quantities neutralized using established procedures for organic peroxides with quenching agent under controlled conditions
Incineration: Destroy only in specially designed and permitted chemical incinerators
Container Disposal: Empty containers may retain hazardous residue; Do not reuse containers; Rinse and dispose of only at licensed hazardous waste facility
Special Instructions: Never dispose into natural environmental media or municipal solid waste streams
