Bisdecanoyl peroxide

Guidance on Safe Use

First-aid measures

General advice:

Take off immediately all contaminated clothing. Risk of ignition. Remove soiled/dirty clothing, brush well and wash carefully.

Dust inhalation or Inhalation of vapours due to thermal decomposition : 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 immediately, abundantly and thoroughly with water. Consult an ophthalmologist.

Ingestion: 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). Heating may cause fire.

Through thermal decomposition, formation of very reactive free radicals.

Thermal decomposition giving flammable and toxic products : Hydrocarbons, Alcohols, Ketones, Carbon oxides

Advice for firefighters: Specific methods:

Fight fire from a distance (more than 15 m). In case of fire nearby, remove exposed containers. Cool containers / tanks with water spray.

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. Avoid 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.

Methods and materials for containment and cleaning up:

Methods for cleaning up: After cleaning, flush away traces with water. Recover waste water for processing later.

Recovery: Never return spills in original containers for re-use. Shovel into suitable container for disposal. Keep contents moist. Do not confine. No

sparking tools should be used.

Handling and storage

Precautions for safe handling:Technical measures/Precautions:

Storage and handling precautions applicable to products: Organic peroxides. Solid.

Provide appropriate exhaust ventilation at machinery. Provide showers, eye-baths. Provide self-contained breathing apparatus nearby (for

emergency intervention). Provide water supplies near the point of use. 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. 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. Avoid contact with the skin and the eyes. Avoid breathing dust or vapor. 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. Use non-combustible construction materials. Keep tightly closed in a dry, cool and well-ventilated

place. Store in original container. Keep away from heat and sources of ignition. Do not smoke. 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.

Provide earthing and safe electrical equipment. Provide impermeable floor.

Storage period: < 6 Months, Storage temperature: < 15 °C (to maintain the technical properties of the product).

Incompatible products:

Strong oxidizing agents, Reducing agents, Strong acids, strong bases, Amines, Sulphur compounds, transition metal salts,

rust, Ash, dusts (risk of self-accelerating exothermic decomposition)

Packaging material:

Recommended: Stainless steel, High density polyethylene (HDPE), Polytetrafluoroethylene (PTFE)

To be avoided: Ordinary metals (ordinary steel), copper, rubber (natural or synthetic)
