Personal Precautions: Evacuate non-essential personnel, ventilate area, keep away from sources of ignition, avoid skin and eye contact, wear recommended PPE (gloves, goggles, coveralls)
Environmental Precautions: Prevent material from entering drains, waterways, or soil
Methods for Clean-Up: Absorb spill with inert material (sand, earth, vermiculite), collect in open containers, do not close tightly, remove residues with plenty of water
Decontamination: Wash area with water and detergent after collection
Waste Disposal: Dispose of as hazardous organic peroxide waste, consult relevant local regulations
Safe Handling: Handle using non-sparking tools, avoid shock, friction, and contamination. Do not return unused product to original container. Keep product away from incompatible materials such as acids, bases, oxidizing agents.
Hygiene Measures: Wash hands and face thoroughly after handling, remove contaminated clothing before entering eating areas.
Conditions for Safe Storage: Store between 2–8°C (35–46°F) in a well-ventilated, cool, dry place, away from direct sunlight and heat sources. Maintain original packaging. Avoid stacking heavy loads. Use temperature monitoring.
Storage Incompatibilities: Keep clear of strong acids, strong bases, reducing agents, and combustibles.
Occupational Exposure Limits: No specific limits for active ingredient, observe national legislation for diluent and workplace organic peroxides.
Engineering Controls: Use local exhaust ventilation, ensure suitable air exchange in process areas.
Respiratory Protection: Use NIOSH-approved respirators in absence of adequate ventilation or if mist/vapor occurs.
Eye Protection: Chemical safety goggles and face shield.
Skin Protection: Full-body coveralls, impervious gloves, apron.
