Administrative data
First-aid measures
General advice : Take off all contaminated clothing immediately.
If inhaled : Provide fresh air. Monitor breathing, seek medical advice immediately.
In case of skin contact : Wash off with plenty of water immediately, seek medical advice if necessary.
In case of eye contact : Rinse immediately with plenty of water and seek medical advice.
If swallowed : Do NOT induce vomiting. Call a physician immediately.
Symptoms : No information available.
Treatment : For specialist advice physicians should contact the Poisons Information Service.
Fire-fighting measures
Suitable extinguishing media : Foam; Carbon dioxide (CO2); Water spray; Dry powder
Specific hazards during fire fighting : No information available.
Special protective equipment for fire-fighters : In the event of fire, wear self-contained breathing apparatus; Protective suit
In the event of fire, cool tanks with water spray.
Accidental release measures
Personal precautions : Keep away from sources of ignition - No smoking ; Ensure adequate ventilation ;Use personal protective equipment.
Environmental precautions : Avoid subsoil penetration ; Do not flush into surface water or sanitary sewer system.
Methods for cleaning up : Confine any leaking material by inorganic, non-acidic, noncombustible, absorbing material (e.g., sand, alkaline alumina,
kieselguhr, vermiculite), take it up and store it in containers to be disposed of in compliance with local/national legal regulations.
Handling and storage
Advice on safe handling : Ensure adequate ventilation ; Do not use lubricants containing heavy metals ;Handle and open container with care.
Advice on protection against fire and explosion: Take precautionary measures against static discharges ; Keep away from sources of ignition - No smoking; Explosion protection equipment required.
Requirements for storage areas and containers : Keep away from direct sunlight; Keep containers tightly closed in a cool, well-ventilated place; Higher temperatures can cause overpressurizing of drums; It is urgently recommended to ensure that the oldest storedmaterial is used first (first in - first out).
German storage class : 5.2L Organic Peroxides, Liquid
: Consult the technical guidelines for the use of this substance/mixture

Exposure controls / personal protection
Engineering measures:
If possible, use material transfer/filling, metering and blending plants that are closed; Provide sufficient air exchange and local exhaust ventilation in work rooms.
Personal protective equipment
Respiratory protection : In inadequately ventilated areas, where workplace limits are exceeded, where unpleasant odours exist or where aerosols
are in use, or smoke and mist occur, use self-contained breathing apparatus or breathing apparatus with a type A filter or appropriate combined filter (e.g. where aerosols are in use, or smoke and mist occur, A-P2 or ABEK-P2), in compliance with EN 141.
Hand protection : The choice of an appropriate glove does not only depend on its material but also on other quality features and is differentfrom one producer to the other., Please observe the instructions regarding permeability and breakthrough time which are provided by the supplier of the gloves. Also take
into consideration the specific local conditions under which the product is used, such as the danger of cuts, abrasion, and the contact time., Be aware that in daily use the durability of a chemical resistant protective glove can be notably shorter than the break through time measured according to EN 374, due to the numerous outside influences (e.g. temperature).
gloves suitable for permanent contact:
Material: butyl-rubber
Break through time: >= 480 min
Material thickness: 0.5 mm
gloves suitable for splash protection:
Material: Polyvinylchloride
Break through time: >= 60 min
Material thickness: 0.5 mm
unsuitable gloves
Material: Natural rubber/natural latex, Polychloroprene,
Nitrile rubber/nitrile latex
Eye protection : face shield
Hygiene measures : Avoid contact with the skin and the eyes; Take off all contaminated clothing immediately; Do not breathe vapours or spray mist.
Protective measures : Wear suitable gloves and eye/face protection.
Environmental exposure controls: Avoid subsoil penetration; Do not flush into surface water or sanitary sewer system.
Stability and reactivity
Reactivity: Risk of violent reaction.
Chemical stability: Organic peroxide. Hazardous decomposition may occur.
Possibility of hazardous reactions: Self-decomposition is catalysed by substances such as acids, tert. amines, Friedel-Crafts catalysts and heavy metals.
Conditions to avoid : Avoid temperatures above 60°C, direct sunlight and contact with sources of heat.
Incompatible materials
Materials to avoid : caustic alkali solutions; mineral acids; oxidation catalysts; Reducing agents; Friedel-Crafts catalysts; Acidic solids
Hazardous decomposition products: phenol; acetone
Disposal considerations
Following pre-treatment and observing the regulations for hazardous wastes, it must be taken to a permitted hazardous wastes landfill or hazardous wastes incinerator.
