First Aid Measures

Inhalation: Remove person to fresh air, keep at rest, seek medical attention for persistent symptoms Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing, consult physician for irritation Eye Contact: Rinse gently with water for at least fifteen minutes, remove contact lenses if present, seek immediate medical advice Ingestion: Do not induce vomiting, rinse mouth, get prompt medical help Most important symptoms/effects: Burning, redness (skin/eyes), coughing, possible headache or dizziness Notes to Physician: Treat symptoms, provide supportive care; monitor for allergic reaction or respiratory distress

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide; avoid using direct water stream Specific Hazards: Organic peroxide decomposition may produce flammable gases, potential for explosive pressure rise in containers Protective Equipment: Full turnout gear and self-contained breathing apparatus required Firefighting Procedures: Isolate area, cool containers exposed to flames, use water spray to reduce vapors Combustion Products: Carbon oxides, hydrocarbons, traces of oxides of nitrogen

Accidental Release Measures

Personal Precautions: Evacuate area, ventilate, isolate and restrict access Protective Equipment: Chemical-resistant gloves, goggles, splash apron, suitable respirator for vapors Spill Cleanup Procedures: Absorb with inert material such as vermiculite, transfer to a suitable container for disposal Environmental Precautions: Prevent runoff into drains, surface waters, inform authorities if contamination likely Decontamination: Wash area with soap and water after material removal, inspect for residues

Handling and Storage

Safe Handling Practices: Avoid friction, shock, heat sources; open containers slowly and carefully Avoided Conditions: Keep away from sunlight, heat, open flame, and incompatible chemicals Storage Requirements: Store in original containers, tightly closed, in cool, dry, well-ventilated place Incompatibles: Reducing agents, acids, alkalis, metal powders, strong oxidizers Special Requirements: Separate from food, feedstuffs, clothing; keep away from combustible material

Exposure Controls and Personal Protection

Occupational Exposure Limits: Not established for specific compound; observe workplace limits for organic peroxides and mineral oil Engineering Controls: Local exhaust ventilation recommended, maintain air concentrations below recommended limits Personal Protective Equipment: Chemical-resistant gloves (nitrile, neoprene), safety goggles, flame retardant lab coat, rubber boots, face shield as needed Respiratory Protection: Use approved respirator for high vapor or dust concentrations Hygiene Measures: Wash hands before breaks and after handling, remove contaminated clothing promptly

Physical and Chemical Properties

Physical State: Oily liquid, dispersed in mineral oil Color: Colorless to pale yellow Odor: Mild, hydrocarbon-like pH: Not applicable Melting Point/Freezing Point: Less than 10°C (pure substance) Boiling Point: Decomposes before boiling Flash Point: Above 80°C (mineral oil mixture) Explosive Properties: Organic peroxide, can detonate under heat/shock/confinement Solubility: Insoluble in water, soluble in organic solvents Vapor Pressure: Low at room temperature Relative Density: 0.85–0.95 (mixture) Decomposition Temperature: Begins near 91°C; exothermic

Stability and Reactivity

Chemical Stability: Stable under recommended storage and handling conditions Reactivity: Can react violently with incompatible materials or by strong ignition sources Possibility of Hazardous Reactions: Exothermic decomposition may occur on heating, contamination, or mechanical shock Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, possibly irritant fumes Incompatible Materials: Strong acids, alkalis, reducing agents, heavy metals Conditions to Avoid: Heat, direct sunlight, friction, shock, contamination

Toxicological Information

Acute Toxicity: Limited oral and inhalation toxicity studies; not classified as acutely toxic at workplace exposures Skin Corrosion/Irritation: Causes moderate irritation, repeated contact may increase sensitivity Eye Damage/Irritation: Causes eye irritation, risk of serious injury if not washed promptly Respiratory Effects: Vapors can cause throat irritation, coughing, possible headaches Sensitization: Repeated exposure may lead to skin sensitization in some individuals Chronic Effects: No reliable data for long-term human exposure; animal studies indicate possible organ effects with large repeat doses Carcinogenicity: Not listed by OSHA, IARC, or NTP as carcinogenic Mutagenicity / Reproductive Toxicity: Available studies do not indicate germ cell effects at occupational exposure

Ecological Information

Aquatic Toxicity: Harmful to aquatic organisms, risk of long-term adverse effects in the aquatic environment Persistence and Degradability: Organic peroxide decomposes in nature, breakdown rate depends on local conditions Bioaccumulation Potential: Mineral oil carrier may persist in soil and water, low for peroxide Mobility in Soil: Carrier can transport active ingredient into waterways; containment reduces risk Other Effects: Localized spill can impact microfauna, planktonic species, and disrupt soil biota

Disposal Considerations

Disposal Methods: Incinerate under controlled high-temperature conditions by licensed waste processor Contaminated Packaging: Clean thoroughly before reuse or recycling, dispose of with hazardous waste Special Precautions: No open burning, avoid landfill unless required by local regulations Environmental Hazards: Keep out of drains, disposal must comply with local, regional, and international regulations Regulatory Advice: Consult local environmental authority for current advisories on organic peroxide disposal
