Chemical Name: LUPEROX(R) A75
Product Type: Organic peroxide-based initiator
Intended Uses: Used in industrial polymerization processes
Physical Form: Typically seen as a paste or damp solid
Exposure Possibilities: Can occur during handling, transfer, or cleanup
User Groups: Works in chemical processing plants, plastics manufacturing, laboratory settings
Main Hazards: May burn or explode if contaminated, heated, or shocked
Health Risks: Can cause skin, eye, and respiratory irritation
Fire and Explosion: Sensitive to friction and impact, releases flammable vapors
Chronic Impacts: Extended exposure can result in skin sensitization
Label Elements: Danger signal word, organic peroxide and irritant symbols
Precautions: Always avoid heat sources, impurities, and incompatible chemicals
Active Ingredient: Organic peroxide (precise chemical structure, often a dialkyl or peroxyester compound)
Concentration: Approximately 75% peroxide in a stabilizing paste
Other Ingredients: Mineral fillers, moistening agents to reduce sensitivity, sometimes phthalates
Impurities: Small traces from manufacturing, usually monitored closely
Skin Contact: Rinse area with plenty of water, remove contaminated clothing
Eye Contact: Rinse immediately under running water for 15 minutes, seek medical attention
Inhalation: Move person into fresh air, monitor breathing, give oxygen if breathing difficulty develops
Ingestion: Rinse mouth, do not induce vomiting, get immediate medical help
Personal Actions: Remove sources of exposure, ventilate area, get professional care
Suitable Extinguishing Media: Water spray, foam, dry chemical, avoid CO2 in enclosed spaces
Special Hazards: Intense heat may trigger violent decomposition releasing gases
Protective Equipment: Full protective gear, self-contained breathing apparatus
Tactics: Cool surrounding areas, keep containers cool with spray, isolate hazard zone
Runoff Concerns: Do not let run-off reach drains or waterways
Personal Precautions: Wear chemical-resistant gloves, eye and face protection, suitable clothing
Environmental Steps: Block flow to sewers and waterways, contain spilled material
Clean-Up Method: Pick up with non-combustible inert material, store in ventilated place
Disposal: Follow hazardous waste rules, consult local regulations
Avoidances: Never use sawdust or other organic absorbents
Handling: Keep away from heat, sparks, direct sunlight, and incompatible chemicals
Storage Temperature: Store below 30°C to slow down decomposition
Incompatibilities: Acids, bases, reducing agents, heavy metal compounds
Packing: Use original containers or containers suitable for organic peroxides
Access Control: Restrict access to trained personnel only
Good Practices: Ground and bond containers, use non-sparking tools
Engineering Controls: Use chemical fume hoods, provide local exhaust
Personal Protection: Safety goggles, face shields, impervious gloves, chemical aprons
Breathing Protection: NIOSH-approved respirators if high vapor levels expected
Skin and Eye: Emergency eyewash stations and safety showers close by
Hygiene: Wash hands and face after handling, avoid eating or drinking in work area
Exposure Limits: No formal OSHA PEL for organic peroxides, but best practices recommend minimizing exposure as much as possible
Form: Paste or semi-solid
Color: White to off-white
Odor: Slightly pungent or solvent-like
Decomposition Temperature: Can begin to decompose above 50°C
Solubility: Not highly soluble in water, dispersible in organic solvents
Flash Point: Will not burn easily but can violently decompose at elevated temperatures
Vapor Pressure: Low under ambient conditions
Chemical Stability: Stable if cool, dry, and uncontaminated
Conditions to Avoid: Heat, friction, shock, contamination with metal ions or acids
Reactivity: Rapid decomposition and gas release if conditions disrupted
Hazardous By-products: Carbon oxides, various organic compounds, vapors
Polymerization Risk: May initiate if spilled onto reactive monomers
Short-Term Exposure: Causes redness, burning, and irritation to skin and eyes
Inhalation Effects: Cough, sore throat, headache, dizziness from fume exposure
Chronic Health Effects: Skin sensitization and allergic reactions possible
Animal Studies: Some organic peroxides cause mild toxicity in lab animals
Carcinogenicity: No strong link established in standard short-term studies
Environmental Fate: Organic peroxides break down in water and soil over time
Aquatic Toxicity: Can be toxic to aquatic organisms in concentrated spills
Bioaccumulation: Unlikely due to breakdown, but caution necessary
Persistence: Does not persist long-term, transforms to simpler molecules
Disposal Impacts: Must not enter natural water systems untreated
Recommended Practice: Incinerate under controlled conditions at authorized facility
Container Handling: Empty containers can still pose dangers—never reuse for other chemicals
Waste Codes: Classed as hazardous waste by most local authorities
Community Protection: Local safety services should know site storage and disposal plan
Small Quantities: Bring to hazardous waste collection points, never landfill or sewer
UN Number: Typically classed as UN 3106 (Organic peroxide, type D, solid)
Transport Hazard Class: Class 5.2, organic peroxides
Packing Group: Special packaging rules for organic peroxides
Transport Practices: Use temperature-controlled transport, protect from physical damage
Reportable Quantities: Shipments must be properly labeled and documented with hazard information
Hazard Classification: Covered under chemical safety and workplace hazard communication rules
Restriction Guidelines: Listed under hazardous substances in most national chemical inventories
Worker Right-to-Know: Regulations in the US and Europe require that employees know the risks
Chemical Use Reporting: Subject to recordkeeping and environmental release reporting
Labelling: Requires clear hazard labels following GHS, OSHA, or EU CLP standards
