FIRST AID

Inhalation:
Move to fresh air immediately if vapors or mists are inhaled.
Seek medical attention if coughing, shortness of breath, or throat irritation persists.
Keep the person at rest and monitor breathing.

Skin Contact:
Remove contaminated clothing immediately and rinse skin with plenty of water.
Wash with soap and water after thorough rinsing.
Seek medical attention if irritation, redness, or burning persists or if exposure was significant.

Eye Contact:
Rinse cautiously with water for several minutes and keep rinsing.
Remove contact lenses if present and easy to do, then continue rinsing.
Seek immediate medical attention due to risk of serious eye injury.

Ingestion:
Rinse mouth with water and do not induce vomiting.
Never give anything by mouth to an unconscious person.
Seek immediate medical attention and show product information if available.

Note to Physicians:
Treat symptomatically and supportively.
Consider oxidizer exposure and potential for chemical burns.
Monitor for respiratory irritation if aerosol exposure occurred.

HANDLING AND STORAGE

Handling:
Use appropriate PPE including chemical-resistant gloves, safety goggles or face shield, and protective clothing.
Avoid skin and eye contact, and avoid breathing vapors or mists.
Use clean, compatible equipment and avoid contamination with metals, rust, dust, or incompatible chemicals.

Ventilation:
Use local exhaust or general ventilation where vapors or mists may be generated.
Use closed transfer systems when feasible to reduce exposure and contamination risk.
Avoid aerosol generation during pumping, mixing, or high-shear operations.

Storage:
Store in a cool, dry, well-ventilated area in original containers designed for organic peroxides.
Keep away from heat, sparks, open flames, direct sunlight, and incompatible materials including reducing agents and combustibles.
Do not return unused material to the original container to avoid contamination.

Spill and Leak Procedures:
Evacuate unnecessary personnel and eliminate ignition sources while maintaining ventilation.
Absorb with inert, non-combustible material and keep spill material away from contaminants.
Dispose of waste according to local regulations and peroxide-specific disposal procedures.

Handling Precautions:
Control temperature during storage and use, and avoid heating unless specifically engineered and monitored.
Do not mix with incompatible chemicals, and do not use contaminated tools or containers.
Rotate stock using FIFO practices and follow supplier safety guidance for organic peroxide products.
