First-aid measures

General:
In all cases of doubt, or when symptoms persist, seek medical attention.
Inhalation
Remove to fresh air. If not breathing, give artificial respiration. Oxygen may additionally be given, by trained
personnel, if it is available. Get medical attention if symptoms occur.
Skin:
Immediately flush skin with plenty of water. Remove contaminated clothing and shoes. Get medical attention if
irritation persists. Wash clothing before reuse. Thoroughly clean or destroy contaminated shoes.
Eye:
Immediately flush eyes with plenty of water. If easy to do, contact lenses should be removed during the
flushing, by trained personnel. Hold the eyelids apart during the flushing to ensure rinsing the entire surface of
the eye and lids with water. Get medical attention if irritation persists.
Ingestion:
Call a physician or a poison control center immediately. Induce vomiting only if directed by medical personnel.
The patient should lie on their left side while vomiting to reduce the risk of aspiration. Never give anything by
mouth to an unconscious or convulsing person.
Indication of any immediate medical attention and special treatment needed:
Persons with pre-existing skin, eye, or respiratory disease may be at increased risk from the irritant or allergic
properties of this material.
Attending physician should treat exposed patients symptomatically.

Fire-fighting measures

Extinguishing media:
waterspray, foam, sand, dry chemical powder, CO2.
Unsuitable extinguishing media
halons.
Hazardous decomposition /combustion products:
CO2, Carbon monoxide.
Acetone, tert-Butanol, Methane, tert-Amyl alcohol, Ethane.
Protective equipment:
Firefighters must wear fire resistant protective equipment. Wear approved respirator and protective gloves.
Other information:
Evacuate all non-essential personnel. Extinguish a small fire with powder or carbon dioxide then apply water to prevent
re-ignition. Cool closed containers with water. Water used to extinguish a fire should not be allowed to enter the
drainage system or water courses. After a fire, ventilate thoroughly the area and soak with water, clean the walls and
metallic surfaces.
Fire and explosion hazard:
CAUTION: reignition may occur. Decomposition under effect of heating (See also Section Hazardous decomposition
products). If involved in a fire, it will support combustion. Vapors may form explosive mixtures with air. In case of fire
and/or explosion do not breathe fumes.

Accidental release measures

Personal precautions:
Do not breathe fumes/vapor. Avoid contact with skin and eyes. For personal protection see Section 8.
Environmental precautions:
Do not allow to enter drains or water courses.
Methods and material for containment and cleaning up
Stop leakage if possible. Eliminate all sources of ignition, and do not generate flames or sparks. Take precautionary
measures against static discharges. Transfer remaining product from leaking container to a clean and suitable
container. Cover the remainder with inert absorbent (e.g. vermiculite) for disposal. Keep contents moist. The waste
should NOT be confined. Flush surroundings with large amounts of water and soap.
Other information:
CAUTION: reignition may occur. Vapors are heavier than air and may spread along floors. Vapors may travel to a
source of ignition and flash back. Evacuate personnel to safe area.

Handling and storage

Precautions for safe handling
Never weigh out in the storage room. When using do not eat, drink or smoke. Do not pipet by mouth. Do not breathe
fumes(vapor. Handle in well ventilated areas. Eliminate all sources of ignition, and do not generate flames or sparks.
Take precautionary measures against static discharges. Apply grounding when transferring from one container to
another. Keep away from reducing agents (e.g. amines), acids, alkalies and heavy metal compounds (e.g.
accelerators, driers, metal soaps). Keep product and emptied container away from heat and sources of ignition.
Confinement must be avoided. Avoid shock and friction. Avoid contact with skin and eyes. Avoid Incompatible
materials (See Section 10).
Fire and explosion prevention
Use explosion protected equipment. Keep away from sources of ignition - No smoking. Use non-sparking tools in
areas where explosive vapor/air mixtures may occur. Do not cut or weld on or near this container even when empty.
Conditions for safe storage
Store in accordance with local/national regulations. Keep away from food, drink and animal feedingstuffs. Store in a
dry well ventilated place away from sources of heat and direct sunlight. Store separate from other chemicals. Keep
only in the original container. Keep container upright to prevent leakage.

Storage
Avoid temperatures below 10 °C. If product freezes or separates, contact Akzo Nobel.
For maximum quality store below: 40 °C.
Other information:
It is recommended to use electrical equipment of temperature group T3. However, autoignition can never be excluded.
Wash hands thoroughly after handling or contact. Keep work clothes separate and do not take them home.

Special precautions for user/ shipper:
Organic Peroxides Type C show under normal transport conditions in original packagings no explosion risk and this
subsidiary risk label is not required for transport. This risk is under all circumstances not present when confinement is
avoided. All packagings used for transport are designed to avoid confinement of the product.
In case of fire the container or packagings must by cooled with plenty of water. Waste should not be confined- spilled
product has to be kept wetted.
For sea- transport: Dispose damaged or leaking receptacles overboard. Flush surroundings with large amounts of
water and wash overboard..

Exposure controls / personal protection

Control parameters:
Ensure good ventilation and local exhaustion of the working area. Explosion proof ventilation recommended.
Personal protection:
Respiratory-
The usual precautionary measures for handling chemicals should be observed.
Hand-
Wear suitable protective gloves of neoprene or synthetic rubber.
Eye-
Wear eye/face protection. A face shield is preferred over goggles.
Skin and body-
Wear suitable protective clothing.
Other information:
Emergency-shower and facilities for rinsing eyes must be accessible. Launder clothes before reuse.

Stability and reactivity

Chemical stability
SADT - (Self accelerating decomposition temperature) is the lowest temperature at which self accelerating
decomposition may occur with a substance in the packaging as used in transport.
A dangerous self-accelerating decomposition reaction and, under certain circumstances, explosion or fire can
be caused by thermal decomposition at and above the following temperature: 80 °C. Contact with incompatible
substances can cause decomposition at or below the SADT 80 °C.

Conditions to avoid:
Avoid temperatures below 10 °C.
To maintain quality store in original closed container below: 40 °C.
Avoid shock and friction. Confinement must be avoided.
Incompatible materials
Avoid contact with rust, iron and Copper. Contact with incompatible materials such as acids, alkalies, heavy metals
and reducing agents will result in hazardous decomposition. Do not mix with peroxide accelerators. Use only Stainless
steel 316, PP, polyethylene orglass-lined equipment .Contact Akzo Nobel for more information.
Possibility of hazardous reactions
Polymerization does not occur.
Hazardous decomposition products
Hazardous decomposition products; Acetone, tert-Butanol, Methane, tert-Amyl alcohol, Ethane.
Other information
Emergency procedures will vary depending on conditions. The customer must have an emergency response plan in
place. Contact Akzo Nobel for assistance with developing an emergency response plan.

Disposal considerations

Product
Due to the high risk of contamination recyclingJrecovery is not recommended. Waste disposal in accordance with
regulations (most probably controlled incineration).
Contaminated packaging
According to local regulations. Emptied container might retain product residues. Follow all warnings even after the
container is emptied. Do not shred containers before they are thoroughly cleaned from product residues.
Other information
For further advice contact manufacturer.
Waste code number
Waste should be regarded as special waste for disposal. Please refer to your specific industry in the European Waste
Catalogue.
