First-aid measures

Description of first aid measures
General advice: Take off contaminated clothing immediately. Never give anything by mouth to an unconscious person. Remove from exposure, lie down. If feeling unwell seek medical advice.
Inhalation: If inhaled remove to fresh air. If cough or other symptoms develops or persists get medical attention.
Skin contact: Wash off with soap and water. Consult a physician in case of eye irritation.
Eye contact: Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.
Ingestion: If swallowed, call a poison control centre or doctor immediately. DO NOT induce vomiting. Never give anything by mouth to an unconscious person.
Most important symptoms and effects, both acute and delayed Symptoms: None known
Indication of any immediate medical attention and special treatment needed: None known.

Fire-fighting measures

Extinguishing media: Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Unsuitable extinguishing media: High volume water jet.
Special hazards arising from the substance or mixture: The product burns violently. Contact with incompatible materials or exposure to temperatures exceeding the SADT may result in a self acceleration decomposition reaction with release of flammable vapors which may autoignite. Cool closed containers exposed to fire with water spray. Containers exposed to temperatures exceeding the SADT (see section 10) may explode. Exposure to combustion products may be a hazard to health. Do not allow run-off from fire fighting to enter drains or water courses.
Advice for firefighters: Evacuate area and fight fire from a safe distance. Containers near the source of fire should be cooled with a water spray to prevent contents from reaching decomposition temperature. Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations. As in any fire, wear self-contained positive-pressure breathing apparatus, and full protective gear.

Accidental release measures

Personal precautions, protective equipment and emergency procedures: Evacuate personnel to safe areas. Wear a self-contained breathing apparatus and appropriate personal protective equipment. (See Section 8 - Exposure Controls/Personal Protection.) Remove all sources of ignition.
Environmental precautions: Obey relevant local, state, provincial and federal laws and regulations. Do not contaminate any lakes, streams, rivers, groundwater or soil.
Methods and material for containment and cleaning up: Organic Peroxide spills should be attended to immediately. Contain spill and absorb with an inert absorbent material and then wet down the mixture with water. Sweep up mixture of spilled organic peroxide and inert absorbent material using non-sparking tools and place in polyethylene bags for disposal. The sweepings in the polyethylene bag should be further wetted with water and disposed of immediately by an approved disposal company. If stored for any period of time, store out of direct sunlight in a cool, well-ventilated place. After all the material has been picked up, wash down the spill area with surfactant and water to remove any traces of organic peroxide. Allow for sufficient ventilation to aid in the removal of fumes that may be present.
Additional advice: Never return spills in original containers for re-use.

Handling and storage

Precautions for safe handling: Keep away from heat. Keep away from sparks, flames and other sources of ignition. Avoid contact with eyes, skin and clothing. Avoid breathing vapor or mist. Use with adequate ventilation. Follow all MSDS/label precautions even after the container is emptied because it may retain product residues. Wash thoroughly after handling. Do not swallow product. Use personal protective equipment. Protect from contamination. Dispense and transfer in an area separate from storage area. Never return unused material to storage receptacle. Wash contact areas after handling. Remove contaminated clothing and wash before reuse. The addition of accelerators may result in vigorous decomposition.
Conditions for safe storage, including any incompatibilities:
Advice on protection against fire and explosion: Containers exposed to temperatures exceeding the SADT (see section 10) may decompose violently. Consult with specialists to ensure design protects against these hazards.
Storage: Heat or contamination may cause hazardous decomposition. Keep containers dry and tightly closed to avoid moisture absorption and contamination. Keep container away from flammable and explosive substances. Protect from heat and exposure to direct sunlight Store in original container. Transport and store container in upright position only.
Further information: Store between +10°C and +30°C. Do not return residues to original container.
Advice on common storage: Store in accordance with the particular national regulations.
Storage stability: > +10 °C to < +30 °C Avoid temperatures below recommended storage temperatures. Store above -10°C to avoid phase separation which could result in safety hazards or performance complications. Avoid confinement.

Exposure controls / personal protection

Exposure controls:
Engineering measures: Use process enclosures, local exhaust ventilation or other engineering controls to control airborne exposure.
Personal protective equipment:
Respiratory protection: Use respiratory protection unless adequate local exhaust ventilation is provided or exposure assessment demonstrates that exposures are within recommended exposure guidelines.
Hand protection: Personal protective equipment that provides a barrier to prevent dermal exposure to this substance is required. Use impermeable gloves. Gloves must be inspected prior to use. The above mentioned hand protection is based on knowledge of the chemistry and anticipated uses of this product but it may not be appropriate for all workplaces. A hazard assessment should be conducted prior to use to ensure suitability of gloves for specific work environments and processes prior to use. Suitability for specific workplaces should be clarified with protective glove manufacturers. Glove material: butyl rubber, Material thickness 0.5 mm, Break through time > 8 hrs
Eye protection: Use chemical splash goggles or face shield.
Skin and body protection: Select appropriate protective clothing based on chemical resistance data and an assessment of the local exposure potential. Wear the following personal protective equipment: Flame retardant antistatic protective clothing. Skin contact must be avoided by using impervious protecting clothing (gloves, aprons, boots, etc.)
Hygiene measures: Remove and wash contaminated clothing before re-use. Wash contact areas after handling. Keep away from food, drink and animal feedingstuffs. All protective equipment that has been contaminated should be cleaned before reuse.
