Fire-fighting measures

Extinguishing media

Suitable extinguishing media: Water spray, Foam.

Special hazards arising from the substance or mixture:

Heating may cause a fire or explosion.

Risk of explosion by shock, friction, fire or other sources of ignition.

The product burns violently (protect people from possible projections),

Contact with combustible material may cause fire.

Through thermal decomposition: formation of very reactive free radicals,

Thermal decomposition giving flammable and toxic products: Alcohols, Carbon oxides (by combustion).

Advice for firefighters:

Specific methods:

Fight fire from a distance (more than 15 m). Cool containers/tanks with water spray.

In case of fire nearby, remove exposed containers.

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 the skin and the eyes. Prohibit inhalation of vapours. 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:

Following product recovery, flush area with water Recover waste water for processing later.

Recovery:

Never return spills in original containers for re-use. Shovel into suitable container for disposal. Small quantities : Soak up with inert absorbent material (Clean sand). Do not confine. No sparking tools should be used.

Elimination: Please refer to "Disposal considerations section".

Handling and storage

Precautions for safe handling:

Technical measures/Precautions:

Storage and handling precautions applicable to products: Organic Peroxides Liquid. Explosives. Toxic. Dangerous for the environment.

Provide appropriate exhaust ventilation at machinery. Provide showers, eye-baths. Provide water supplies near the point of use. Provide selfcontained breathing apparatus nearby. Provide fire-blanket nearby. Provide electrical earthing of equipment and electrical equipment usable in explosive atmospheres.

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. Avoid contact with the skin and the eyes. Prohibit inhalation of 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 containers tightly closed in a cool, well-ventilated place. Keep away from heat and sources of ignition. Do not smoke. Use non-combustible construction materials. Keep/Store away from clothing/ combustible 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 electrical earthing of equipment and electrical equipment usable in explosive atmospheres. Provide impermeable floor.

Storage period: < 6 Months, Storage temperature: < 10 °C

Incompatible products:

Strong oxidizing agents, Reducing agents, Acids, Bases, Amines, Sulphur compounds, heavy metal compounds, heavy metals, 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), Glass - Stoneware (risk of contents spurting or spraying out if container ruptures due to overpressurization)

Specific end use(s): None.
