Guidance on Safe Use

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:

Inhalation of vapours/mists : Move to fresh air. Oxygen or artificial respiration if needed. Keep under medical surveillance. In case of problems

: Hospitalise.

Skin contact:

Wash immediately, abundantly and thoroughly with soap and water. If significant contact: Keep under medical surveillance. In case of

problems : Hospitalise.

Eye contact:

Wash well-open eyes immediately, abundantly and thoroughly with water. If irritation persists, consult an ophthalmologist.

Ingestion:

Do NOT induce vomiting. Hospitalise.

Protection of first-aiders:

In case of insufficient ventilation, wear suitable respiratory equipment. Protective suit.

Fire-fighting measures

Extinguishing media:

Suitable extinguishing media: Water spray, Foam

Special hazards arising from the substance or mixture:

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, Ketones, Hydrocarbons, 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, 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 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 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. Small quantities : Soak up with inert absorbent

material (Vermiculite, Clean sand). Do not confine. No sparking tools should be used.

Handling and storage

The following information is related to the handling and storage of the peroxide phlegmatised. This organic peroxide is not produced (and therefore not used) as pure substance.

Precautions for safe handling:Technical measures/Precautions:

Storage and handling precautions applicable to products: Organic peroxides. Liquid. Harmful. Irritant. 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.

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. 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 a catch-tank in a bunded area. Provide impermeable floor.

Storage period: < 6 Months, Storage temperature: < -10 °C (typical value for peroxide diluted at 50%)

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: 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.
