Inhalation: Move affected person to fresh air, keep at rest, call for immediate medical attention if symptoms such as coughing, shortness of breath, or dizziness occur
Skin Contact: Remove contaminated clothing, wash exposed area thoroughly with soap and water for at least 15 minutes, do not delay, seek medical advice for irritation or burns
Eye Contact: Rinse cautiously with water for 15–20 minutes, remove contact lenses if present, keep eyes wide open, obtain medical evaluation urgently
Ingestion: Rinse mouth, never induce vomiting, seek immediate medical help
Special Notes for Physicians: Treat symptomatically, risk of delayed pulmonary effects, monitor for chemical burns and secondary infections
Suitable Extinguishing Media: Flood area with large quantities of water or use water spray to cool containers. Dry chemical or carbon dioxide may be ineffective against large fires involving peroxides.
Unsuitable Media: Avoid foam or dry powder unless specified for peroxides, avoid halogenated extinguishers.
Specific Hazards: Organic peroxide will decompose rapidly if heated, risking violent fire or detonation. Combustion may release toxic fumes such as carbon oxides, sulfur oxides, and acidic vapors.
Protective Equipment: Full firefighting turnout gear including self-contained breathing apparatus, isolation from spill until secure.
Firefighting Instructions: Withdraw to safe distance if fire cannot be controlled, cool containers exposed to fire with large amounts of water even after fire is out due to risk of re-ignition.
Personal Precautions: Evacuate non-essential personnel, eliminate ignition sources, ventilate area as much as possible, wear full chemical protective clothing and respiratory protection.
Environmental Precautions: Prevent entry into drains, sewers, groundwater or open waterways, alert local authorities in case of large spills.
Cleanup Methods: Collect leaking material with non-reactive tools (plastic or Teflon scoop), absorb with inert material like vermiculite, avoid using sawdust or cloth rags. Place in sealed, labeled container for safe disposal.
Decontamination: Wash area with large amounts of water after cleanup, avoid strong oxidizers or reducers during clean-up.
Handling: Use only in chemical fume hood or with working local exhaust ventilation. Avoid friction, impact, or direct sunlight. Handle with electrically grounded equipment. Use spark-proof tools.
Storage: Store in tightly sealed containers in a cool, well-ventilated, dedicated peroxide storage room away from heat, direct UV, and incompatible chemicals such as acids, bases, heavy metals, or reducing agents.
Storage Temperature: Maintain below 25°C for stability, regularly rotate stocks by date received.
Safe Packaging: Keep in original container, away from metal shelving, avoid glass packaging if risk of shock.
Special Restrictions: Never store with food, feeds, or incompatible chemicals.
Exposure Limits: No OSHA, ACGIH, or NIOSH established limits; consider as nuisance dust or vapor, follow workplace exposure monitoring if available.
Engineering Controls: Use chemical fume hood, general room ventilation, emergency eyewash and safety shower stations nearby.
Respiratory Protection: NIOSH-approved respirators for organic vapors or supplied-air respiratory protection if airborne levels are above nuisance concentration.
Hand Protection: Chemical-resistant gloves (nitrile, neoprene, or PVC). Double-gloving recommended for spill response.
Eye Protection: Tight fitting safety goggles with face shield.
Skin Protection: Chemically resistant body suit, closed shoes, and full-length pants.
Hygiene Recommendations: Wash hands before breaks and after handling chemicals, do not eat, drink, or smoke before thoroughly cleaning exposed skin.
Appearance: Clear to slightly cloudy colorless to pale yellow liquid
Odor: Slight chemical odor, may resemble acetone or organic solvents
Odor Threshold: Not available
pH: Not determined
Melting Point/Freezing Point: Below standard room temperature
Boiling Point: Decomposes before boiling
Flash Point: Below 60°C (closed cup, based on diluent)
Evaporation Rate: Not established
Flammability: Organic peroxide—strong oxidizing ability, not directly flammable but accelerates burning
Upper/Lower Explosion Limits: No reliable data due to decomposition risk
Vapor Pressure: Not determined
Vapor Density: Heavier than air (based on diluent)
Solubility: Partially soluble in organic solvents, negligible in water
Partition Coefficient (n-octanol/water): Not measured
Decomposition Temperature: Rapid self-accelerating decomposition possible above 50°C
Viscosity: Similar to light organic liquids, varies with exact diluent blend
Chemical Stability: Unstable if heated, shocked, or contaminated. Decomposes rapidly at elevated temperatures releasing energy and gases.
Conditions to Avoid: Exposure to heat above recommended storage, physical shock, friction, sources of ignition or incompatibles.
Materials to Avoid: Strong acids and bases, reducing agents, heavy metals, amines, flammable solvents, combustibles.
Hazardous Decomposition Products: Carbon dioxide, carbon monoxide, sulfur oxides, corrosive vapors.
Hazardous Polymerization: Will not occur but may violently decompose.
Likely Routes of Exposure: Inhalation of vapors or mist, skin and eye contact, accidental ingestion
Acute Toxicity: Harmful if swallowed or inhaled. Can cause severe burns to skin and eyes on contact.
Skin Corrosion/Irritation: Causes severe irritation, possible permanent tissue damage.
Serious Eye Damage/Irritation: High risk of irreversible injury, including blindness.
Respiratory Sensitization: Possible allergic or asthmatic reactions, especially after repeated exposures.
Skin Sensitization: Allergic contact dermatitis reported in susceptible workers.
Chronic Effects: Prolonged or repeated exposure can result in dermatitis, chronic respiratory irritation.
Carcinogenicity: Not classified as carcinogen by IARC/OSHA/NIOSH as per available data.
Mutagenicity/Reproductive Toxicity: No data to suggest mutagenic or reproductive toxic properties.
Ecotoxicity: Toxic to aquatic organisms with possibility of long lasting adverse effects in aquatic environment.
Persistence and Degradability: Will degrade in environment but forms persistent, hazardous byproducts.
Bioaccumulative Potential: Limited potential due to reactivity; breakdown products may bioaccumulate.
Mobility: Low in soil due to reactivity; risk of contamination of surface water during spill.
Other Adverse Effects: No information on ozone or greenhouse gas potential.
Waste Disposal Methods: Dispose through licensed hazardous waste processor familiar with organic peroxides
Contaminated Packaging: Decontaminate containers with copious water before disposal or incineration.
