Precautionary Statements

P210: Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking.

P235: Keep cool.

P280: Wear protective gloves/protective clothing/eye protection/face protection.

P273: Avoid release to the environment.

Store in a cool, dry, and well-ventilated area with a maximum storage temperature of 30°C. Recommended long-term storage temperature: 2-8°C

Avoid exposure to direct sunlight, heat sources, and incompatible materials like acids, bases, reducing agents, and heavy metals.

Keep containers tightly closed when not in use and store under inert gas when possible. Storage stability is typically 12 months under recommended conditions

Inhalation: Move to fresh air. If breathing is difficult, give oxygen. Seek medical attention .

Skin Contact: Remove contaminated clothing. Wash skin thoroughly with soap and water. Seek medical attention if irritation persists .

Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present. Continue rinsing. Seek immediate medical attention.

Ingestion: Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Seek immediate medical attention.

Use water spray, powder, foam, or carbon dioxide to extinguish fires involving Dicumyl Peroxide.

Cool exposed containers with water spray from as far a distance as possible. Evacuate area for a radius of 2500 feet if the material is involved in fire.
