Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data

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 of vapours/mists : Move to fresh air. Oxygen or artificial respiration if needed. In case of persistent problems : Hospitalise.

Skin contact: Wash immediately, abundantly and thoroughly with soap and water. If skin irritation persists, call a physician.

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

Ingestion: Do NOT induce vomiting. Consult a physician.

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

Fire-fighting measures

Suitable extinguishing media: Water spray, foam, Carbon dioxide (CO2), Dry powder

Special hazards arising from the substance or mixture:

Heating may cause a fire.

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

Through thermal decomposition, formation of very reactive free radicals.

Thermal decomposition giving flammable and toxic products :

Alcohols, Ketones, Ethane - Methane - Ethylene, Carbon oxides, Hazardous organic compounds

Contact with materials to avoid or exposure to temperatures exceeding the SADT may result in a self-accelerating decomposition reaction

with release of flammable vapors which may autoignite.

Advice for firefighters:

Specific methods: Fight fire from a distance (more than 15 m). Cool containers/tanks with water spray. In case of fire, 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. Prohibit contact with skin and eyes and 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: 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. Do not confine. Small quantities : Soak up with inert absorbent material (Clean sand). 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. Liquid. Flammable. Irritant.

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 (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). In case of insufficient ventilation, wear suitable respiratory equipment. Avoid accumulation of static

charges during transfers in metallic systems.

Hygiene measures:

Take off immediately all contaminated clothing. Prohibit contact with skin and 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. 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. 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. Provide earthing and safe electrical equipment. Provide a catch-tank in a bunded area.

Provide impermeable floor.

Storage period: < 6 Months, Storage temperature: < 30 °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), Glass - Stoneware (risk of contents spurting or

spraying out if container ruptures due to overpressurization)
