Guidance on Safe Use
Administrative data
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 : 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. If irritation persists, consult an ophthalmologist.
Ingestion: Do NOT induce vomiting. In case of problems : Consult a doctor.
Protection of first-aiders: Dusts : In case of insufficient ventilation, wear suitable respiratory equipment.
Fire-fighting measures
Suitable extinguishing media: Water spray, Carbon dioxide (CO2), Dry powder, Foam
Special hazards arising from the substance or mixture:
Heating may cause a fire.
Through thermal decomposition, formation of very reactive free radicals.
The product burns violently (protect people from possible projections).
Thermal decomposition giving flammable and toxic products :
Hydrocarbons, Propanone, Tertiobutanol, Carbon oxides
Precautions for fire-fighters: 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. Prohibit all sources of sparks and ignition - Do not smoke. Do not allow run-off from fire fighting to enter drains or water courses.
Special protective actions for fire-fighters: In the event of fire, wear self-contained breathing apparatus.
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. Absorb the remainder with an inert absorbent material. Shovel into suitable container for disposal. Do not confine. No sparking tools should be used.
-Elimination:
Disposal of product: Do not dispose of waste into sewer. Destroy the solid product by incineration of small quantities at an approved waste disposal site only (in accordance with local and national regulations). Amount of active oxygen must be below 1%. Can be disposed of as waste water, when in compliance with local regulations.
Disposal of packaging:
Do not release into the environment. Destroy packaging by incineration at an approved waste disposal site (in accordance with local and national regulations).
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 water supplies near the point of use. Provide self-contained breathing apparatus nearby (for emergency intervention). 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. Avoid the formation and deposition of dust. In case of dust formation, wear a dust mask. Take precautionary measures against static discharges. Protect from contamination. Never return any product to the container from which it was originally removed (risk of decomposition). In case of insufficient ventilation, wear suitable respiratory equipment.
Hygiene measures:
Remove and wash contaminated clothing before re-use. Avoid contact with the skin and the eyes. Avoid 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. Use non-combustible construction materials. Keep tightly closed in a dry, cool and well-ventilated place. Keep away from heat and sources of ignition. Do not smoke. 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. Provide earthing and safe electrical equipment. Provide impermeable floor. Store in accordance with the particular national regulations.
Storage temperature: < 30 °C (to maintain the technical properties of the product).
Storage period: < 12 Months
Incompatible products:
Strong oxidizing agents, Reducing agents, Strong acids, strong bases, Amines, Sulphur compounds, heavy metal compounds, heavy metals, rust, Ash, dusts (risk of self-accelerating exothermic decomposition)
Packaging material:
- Recommended: 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)
Specific use(s) (End Use): None.
