Print date: May 7, 2007 Edition: 07 created/revised in April 2007 Seite: 2/9
R 34 Causes burns.
R 48/20/22 Harmful: danger of serious damage to health by prolonged exposure through inhalation and if
swallowed.
R 51/53 Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment.
R 65 Harmful: may cause lung damage if swallowed.
Classification system:
The classification was made according to the latest editions of the EU-lists, and expanded using company
data and specialized literature.
Information on cumene hydroperoxide:
Cumene hydroperoxide can also be absorbed through the skin. Vigorous reaction on contact with acids.
Thermal decomposition begins above 80 癈 very slowly and may go off spontaneously above 140 癈.
Information on cumene:
Cumene is readily absorbed through the skin. Cumene-saturated water in stagnant waters and canals
evolves sufficient cumene to form ignitable mixtures above the water surface. The vapours are heavier than
air.
Additional information: Symptoms at the respiratory tract may still occur some hours after an over-
exposure.
4. First-aid measures
General information: Bring injured persons to the fresh air, lie comfortably and loosen tight clothing. Do
not let injured persons cool-out. In the case of vomiting or danger of
unconsciousness, lie and transport in stabilised side position. Call a doctor to the
site of the accident.
After inhalation: Provide fresh air. Call a doctor to the site of the accident immediately.
After skin contact: Take-off drenched clothing, shoes and stocking immediately, thereby observing
self-protection (e.g. gloves). Rinse affected parts of the body for a long time with
plenty of water. If large areas of the skin are wetted, immediately call a doctor to
the site of the accident, otherwise immediately visit a doctor in any case.
After eye contact: Rinse the eyes with opened eyelids with water for at least 15 minutes. Thereafter
immediately consult an eye specialist.
After swallowing: Rinse the mouth with water and drink plenty of water. Do not induce vomiting. Call
a doctor to the site of the accident immediately.
Information for the doctor:
Symptoms and dangers: Vapours irritate the respiratory tract and the lungs. Lung oedema are possible.
Caution, a weak-symptoms or symptom-free interval is possible. The liquid can be absorbed through the
skin. Irritation of or caustic burns on the skin and mucous membranes.
Treatment: Thoroughly clean the wetted skin areas with water. After eye contact, rinse with plenty of water,
in case of caustic burns send to an eye specialist or eye clinic, if possible with continuous rinsing. In case of
inhalation, to prevent lung oedema, initiate inhalative cortisone therapy as soon as possible (e.g. every 10
minutes 5 strokes of a cortisone-containing dosing aerosol such as Auxiloson, Thomae). Administer codeine
against irritation coughing. In case of commencing or manifested pulmonal oedema administer systemic
cortisone (e.g. Solu Decortin 1000 or Fortecortin 100). If swallowed, purge the stomach after intubation,
administer activated charcoal, saline laxatives.

5. Fire-fighting measures
Suitable extinguishing media: Water spray jet, dry powder extinguisher, alcohol-resistant foam, carbon
dioxide (CO2). Water is preferable on account of its cooling effect.
Extinguishing media which must not be used for safety reasons: Direct water jet (danger of spreading).
Special exposure hazards arising from the substance or preparation itself, combustion products,
resulting gases: Dangerous decomposition product see section 10: stability and reactivity.
Special protective equipment for fire fighters: Wear self-contained respiratory protective device. Wear
fully protective suit. During clearance wear protective clothing and rubber boots.
Additional information: In case of fire, cool endangered containers with water jets. If possible, drag them
away out of the hazard zone. Dispose of fire debris and contaminated fire fighting water in accordance with
official regulations. Collect contaminated fire fighting water separately. It must not enter the sewage system.
6. Accidental release measures
Personal precautions: Move uninvolved persons towards the weather side (windward). Do not inhale the
vapours. Wear protective clothing when carrying out repair work. Wear respirator equipment if necessary.
Environmental precautions: Prevent discharge into the sewage system/water resources/soil (toxic for
aquatic organisms). In case of seepage into the ground, water course or sewage system inform responsible
authorities.
Methods for cleaning up/collecting: Cover residues with non-combustible absorbent (absorbents, sand,
dry soil, ground chalk) and send for disposal in suitable receptacles. Dispose contaminated material as
waste according to section 13.
Additional information: None.
7. Handling and storage
Handling
Information for safe handling: Ensure good ventilation at the working site to remove dust. Maximum filling
height 90 %. Do not return removed quantities into the container. Observe strict cleanliness in the room.
Destroy residues.
Information about protection against fire and explosion: Keep sources of ignition away. When
transferring between vessels, use grounded apparatus and equipment which does not produce sparks.
Protect against heat. Emergency cooling must be available in case of nearby fire.
Storage
Requirements to be met by storerooms and receptacles: Shelves must be made only of aluminium.
Vessels must be made of V2A steel, glass or ceramics. Attacks rubber. Do not use any auxiliary devices
made of plastics. Store in a well-ventilated place. Store cool; recommended storage temperature below
25 癈. Protect the container against direct solar radiation. Keep the containers tightly closed.
Information about storage in one common storage facility: Do not store together with highly flammable
and combustible substances. Follow regulations for flammable liquids.
Other information on storage conditions: None.
Storage class: No.: 5.2 L (organic peroxides).

(2000/39/EC)
Personal protective equipment
Breathing equipment: Use respirator filter unit with gas filter DIN EN 141 Type A (colour code
brown): Up to 0.1 vol.% class 1; up to 0.5 vol.% class 2; up to 1 vol.% class
3; above 1% and if conditions are unclear, environmentally independent
respirator device.
Hand protection: Wear resistant protective gloves (tested according to DIN EN 374). Avoid
direct contact with the chemical/ the product/ the preparation by
organizational measures. The glove material has to be impermeable and
resistant to the product/ the substance/ the preparation. Check protective
gloves prior to each use for their proper condition.
After use of gloves apply skin-cleaning agents and skin cosmetics. Selection
of the glove material on consideration of the penetration times, rates of
diffusion and the degradation
Material of gloves: Fluorocarbon rubber, PVC
The selection of suitable depends upon the material, and also upon the
quality of the gloves. The degree of protection will vary from manufacturer to
manufacturer. As the product is a preparation of several substances, the
resistance of the glove material can not be calculated in advance and has
therefore to be checked prior to the application.
Penetration time of glove material:
480 min. (Fluorocarbonrubber)
60 min. (PVC)
The exact break-through time has to be found out by the manufacturer of the
protective gloves and has to be observed.
Eye protection: Basket goggles (DIN EN 58211, number 3), face protection shield.
Protective clothing: Robust closed shoes, PVC jacket, PVC trousers with bib, Apron.
General protective and hygiene measures: Do not inhale the vapours. Avoid contact with eyes and skin.
Take off dirty drenched clothes. Keep away from food and drink. Precautionary skin protection: Protective
cream based on polyvinyl alcohol. Before breaks and at the end of work, wash the hands with soap and
water, then apply lanolin cream.
