After thatgets medical treatmenL In case eyes to do contact lenses, if don,t stickeyes, remove lenses then wash eyes.In case be consciousness, immediately rinses out mouth then give acup of water. After that gets medical treatment. And don't inducevomiting. In case be unconsciousness, immediately get medicaltreatment. At the time if vomiting occurs, the patient should lie ontheir left side while vomiting to reduce the risk of aspiration.

Method of extinguish a fire: Extinguish a small fire wrth powder or carbon dioxide ten apply

water to cool. Extinguish a big fire with water bar or spray or foam orreinforced liquid then apply water to cool. Escape the fire wrth manywater

Protect for the fire fighter : Must wsrr proper protective equipment. Extinguish a fire from thewindward for avoids inhalation poisonous gas. Keep the safetydistance because there is an explosion hazard.

6. Accidental Release MeasuresCaution for Human : Must wear proper protective equipment and work from the windward.

Stretch rope at leaking area and keep out except person concerned.Ventilate at leaking area, if necessary

Caution for environment : Don't allow direct to enter drain or water courses.Method for cleaning up : In case small, wipe off wrth cloth then burns in safety space

immediately. In case large, stop an outflow with earth and sand theneollect. Adsorbs remainder wrth sawdust, diatomite or dry sand thendisposes of proper Soaks water if keeps for the time.

Prevention for secondaly disaster: Remove the sources of ignition in neigborhood immediately. Use the

safety tools as don't generate sparks.

7. Handling and StorageHandling

Storage

: Handle well in ventilated area. Wear proper protective equipment forguard eyes and skin. Avoid strong rubbing and shock. Eliminate allsources of ignition, and don't generate flames or sparks. Keep awayfrom reducing agents, amines, acrds, alkalies and heavy metalcompounds.Use materials of equipment stainless steel, glass lining, polyethylene.Don't use irons, copper compounds, leads, and rubbers. Takemeasures for static electricity as ground. Use explosion protectedequipment. Wash empty container with water at once, after then putthe cap and avoid the direct sunlight.

: Store in accordance with local and national regulations. Keep in thecool dark place of less than 30'C. Don't use fire. Keep away fromfood, drink and other chemicals, especially amines, acids, alkalies,heavy metal compounds and reduction agents. Take measures for thefall and the fall prevention. Must not put the horizontal and thereverse.

: Use materials stainless steel, glass lining, polyethylene for avoidsdecomposition.

8 Exposure Controls and Human ProtectionEquipment : Set the local exhaust ventilation when gas and mist are generated. Set

the washing tool for eyes and body. Use explosion protectedequipments. Take measures the static electricity.

13. Disposal C onsiderationGeneral : It disposes properly according to the law in each country and the

regron.Incinerate : Use proper incinerator. When the incineration is done,it incinerates

little by little mixing it with an inert high boiling point solvent. Or,the diatom soil and the vermiculite, etc. are made to absorb it and itburns. If there is no proper rncinerator, the consignment disposal isdone to the industrial waste trader who obtains permission.

Contaminated packing : Removed contents completely after then incinerated.

I 4. Transport InformationGeneral : It disposes properly according to the law in each country and the

regron.Classification : 5.2 Organic PeroxideUN Number : 3105 Organic Peroxide type D liquidSea transport : Follow method of transport, be provided in IMDGAir transport : Follow method of transport, be provided in IATA.Safety measures : Thke measures for the fall and the fall prevention, for prevent

leakage. The top of container tumed upward, must not put thehorizontal and the reverse. When transport, keep out inflammable.Avoid direct sunlight and heat.
