4. First aid measures
First aid measures / general indications
Remove contaminated clothes without delay.
First Aid measures / inhalation
Take the patient out of the dangerous area, provide for fresh
air, then seek immediately for medical attention.
First Aid measures / skin contact
Wash with plenty of water and soap. In case of rash, medical
attention is necessary.
First Aid measures / eye contact
Rinse immediately with plenty of water (for at least 15 minutes),
then call for a doctor.
First Aid measures / ingestion
Do not induce vomiting. Seek immediately for medical attention.
5. Fire-fighting measures
Appropriate extinguishing media
Water spray, foam, extinguishing powder
Carbon dioxide
Water spray in large amounts, from a safe distance. Small fires
can also be extinguished with powder or carbon dioxide, in such
cases however prolonged spraying of water is required, to
prevent the fire from starting anew.
Extinguishing media that must not be used for safety reasons
Halons
Special hazards arising from the product itself, from
combustion products or from resulting gases
In case of fire the product supports the combustion.
Do not inhale explosion or combustion gases. See also point 10.
Special protective equipment for fire-fighters
Wear protective clothing and self-contained breathing apparatus.
Additional information
Cool threatened containers with water in case of fire.
6. Accidental release measures
Do not let this product enter into soil, water and drains.
Remove sources of ignation, provide sufficient ventilation.
Keep unauthorised persons at a distance.
Take up with a polyethylene shovel, store temporarily in a clean
cask with a loose lid in a safe place and dispose as soon as
possible according to the local legislative provisions.

7. Handling and storage
Handling
This product is sensitive to heat and many foreign substances, in
particular amine accelerators. See also point 10. Follow clean
work procedures. Close containers immediately after drawing out
product.
Never mix with the accelerator. When using polyester resin, this
product must be dosed and mixed separately.
Never store peroxides in a confined space, so that no dangerous
built-up can take place after possible decomposition.
Do not expose to foreign substances promoting decomposition, do
not expose to heat and direct sunlight.
Keep away from sources of ignition - no smoking.
This product is combustible, explosive decomposition
is possible under unfavourable conditions.
Take mesaures against explosion. Earth when emptying and
filling cask.
Store only in original, closed containers, away from other
substances. Storage temperature max. +25 °C.
Keep away from food, drink and animal feeding stuffs
8. Exposure controls/personal protection

including reducing agents (e.g. amine accelerators),
heavy metals compounds (particularly cobalt
accelerators), acids and bases, can lead to dangerous,
autoaccelerating decomposition reactions, which may
result in explosion or fire.
