First-aid measures

General advice:
Take off immediately all contaminated clothing (Risk of ignition).
In case of splashes, remove contaminated clothing and plunge it into water immediately.

Inhalation: Move to fresh air. Oxygen or artificial respiration if needed. In case of persistent problems : Consult a physician.

Skin contact: Wash immediately, abundantly and thoroughly with soap and water.

Eye contact: Wash well-open eyes immediately, abundantly and thoroughly with water. Consult an ophthalmologist.

Ingestion: Do NOT induce vomiting.
In case of problems : Consult a doctor.

Protection of first-aiders: In case of insufficient ventilation, wear suitable respiratory equipment. Protective suit

Fire-fighting measures

Suitable extinguishing media: Water spray, After cooling , Dry powder

Special hazards arising from the substance or mixture:
The product burns violently (protect people from possible projections), Risk of explosion by shock, friction, fire or other sources of ignition.
Contact with combustible material may cause fire. Through thermal decomposition, formation of very reactive free radicals.
Thermal decomposition giving flammable and toxic products

Precautions for fire-fighters: Specific methods:
Fight fire from a distance (more than 15 m). Containers/tanks should be cooled with water spray. In case of fire nearby, remove exposed containers. Prohibit all sources of sparks and ignition - Do not smoke.

Special protective actions for fire-fighters: Wear self-contained breathing apparatus and protective suit.

Accidental release measures

Personal precautions, protective equipment and emergency procedures:
Evacuate non-essential staff and those not equipped with individual protection apparatus. Prohibit all sources of sparks and ignition - Do not smoke. Prohibit contact with skin and eyes and inhalation of dust. Use personal protective equipment. In case of insufficient ventilation, wear suitable respiratory equipment

Environmental precautions:
Do not release into the environment. Do not let product enter drains. Avoid subsoil penetration. Do not flush into surface water.

Methods and materials for containment and cleaning up:
- Methods for cleaning up: Never return spills in original containers for re-use. Pick up and transfer to properly labelled containers.
- Recovery: Shovel or sweep up. Shovel into suitable container for disposal. Keep contents moist. No sparking tools should be used.
After cleaning, flush away traces with water. Recover waste water for processing later.

Handling and storage

Precautions for safe handling: Technical measures/Precautions:
Storage and handling precautions applicable to products: Organic Peroxides Solid. Explosives. Irritant. Sensitizing. Dangerous for environment.Provide appropriate exhaust ventilation at machinery. Provide showers, eye-baths. Provide high flow water point nearby. Provide self-contained breathing apparatus nearby. Provide fire-blanket nearby. Provide electrical earthing of equipment.

Safe handling advice:
Strictly limit the quantities of product in the work area to those which are absolutely necessary for the work in hand. Great cleanliness in work areas is a necessary and important factor for safety. Handle and open container with care (risk of overpressurization in containers). Prohibit all sources of sparks and ignition - Do not smoke. Protect from contamination. Never return any product to the container from which it was originally removed (risk of decomposition). Never mix peroxides directly with accelerators (risk of explosion). Add each component separately to the resin. In case of insufficient ventilation, wear suitable respiratory equipment

Hygiene measures:
Take off immediately all contaminated clothing. Prohibit contact with skin and eyes and inhalation of dust (or vapours). When using do not eat, drink or smoke. Wash hands after handling. Remove contaminated clothing and protective equipment before entering eating areas.

Conditions for safe storage, including any incompatibilities:
Store in well insulated area (peroxide area) away from other substances. Storage buildings must be built and equipped so as not to exceed the maximum proscribed temperature limit. Keep tightly closed in a dry, cool and well-ventilated place. Keep away from heat and sources of ignition. Do not smoke. Use non-combustible construction materials. Store in original container. Use only very clean containers and equipment free from traces of impurities. Never return unused material to storage receptacle. Do not reuse empty packaging to store other products. Protect the containers from any impacts. Provide earthing and safe electrical equipment. Provide impermeable floor. Consult ARKEMA before storage design. Storage period: < 6 Months Store between: 5 °C to 30 °C

Incompatible products:
Strong oxidizing agents, Powerful reducers, Acids, Bases, Amines, Sulphur compounds, heavy metal compounds, heavy metals, rust, Ash, dusts (risk of self-accelerating exothermic decomposition)

Packaging material:
- Recommended: Keep only in the original container., High density polyethylene (HDPE), Polytetrafluoroethylene (PTFE), Stainless steel
- To be avoided: Ordinary metals (ordinary steel), copper, rubber (natural or synthetic), Glass - Stoneware (risk of contents spurting or spraying out if container ruptures due to overpressurization)
