      · Prevent formation of aerosols.

      · Wear suitable respiratory protective device when decanting larger quantities without extractor facilities.

      · Do not refill residue into storage receptacles.

      · Restrict the quantity stored at the work place.

      · Before break and at the end of work hands should be thoroughly washed.

      · Only use tools made of suitable materials (e. g. polyethylene or stainless steel).

      · Keep away from dirt, rust, chemicals in particular concentrated acids, alkalis and accelerators (e. g. heavymetal compounds and amines).

      · Oxidizing because of releasing oxygene.

      · While using do not eat, drink or smoke.

      · Do not generate flames or sparks.

      · Keep product and emptied container away from heat and sources of ignition.

      · Avoid shock and friction.

      · Take precautionary measures against static discharges.

      · Do not smoke.

Information about fire - and explosion protection:

      · Protect from heat.

      · Protect against electrostatic charges.

      · Prevent impact and friction.

      · Use explosion-proof apparatus / fittings and spark-proof tools.

      · Fumes can combine with air to form an explosive mixture.

      · Wear shoes with conductive soles.

      · Formation of flammable or explosive gas/air-mixtures is possible.

      · Avoid open flames, sparks, direct sunlight and other sources of ignition.

      · Keep ignition sources away - Do not smoke.

Conditions for safe storage, including any incompatibilities:

      · Storage: Pay attention to the special requirements of your local authorities for storing dangerous goods.

      · Requirements to be met by storerooms and receptacles: Store only in the original receptacle. Prevent any seepage into the ground. Use only receptacles specifically permitted for this substance/product.

      · Information about storage in one common storage facility: Do not store or park organic peroxide together with heavy metal compounds and amines. Store away from foodstuffs, drinks and feeding stuffs.

      · Further information about storage conditions: Protect from heat and direct sunlight. Protect from contamination.

      · Recommended storage temperature (To maintain quality): max.: +30 °C

Exposure controls / personal protection

Control parameters

· Ingredients with limit values that require monitoring at the workplace: The product does not contain any relevant quantities of materials with critical values that have to be monitored at the workplace.

· Additional information: The lists valid during the making were used as basis.

Exposure controls

· Personal protective equipment:

      · General protective and hygienic measures:

             The usual precautionary measures are to be adhered to when handling chemicals.

             Keep away from foodstuffs, beverages and feed.

             Immediately remove all soiled and contaminated clothing

             Wash hands before breaks and at the end of work.

             Store protective clothing separately.

             Avoid contact with the eyes.

             Do not eat, drink, smoke or sniff while working.

             Use skin protection cream for skin protection.

             Be sure to clean skin thoroughly after work and before breaks.

      · Respiratory protection:

             Not necessary if room is well-ventilated.

             Use suitable respiratory device when it exceed exposure limit and when insufficiently ventilated.

             Filter A2

      · Protection of hands:

             Only use chemical-protective gloves with CE-labelling of category III.

             Selection of the glove material on consideration of the penetration times, rates of diffusion and the degradation

      

      · Material of gloves:

             The selection of the suitable gloves does not only depend on the material, but also on further marks of quality and varies from manufacturer to manufacturer.

             Butyl rubber, BR

             Fluorocarbon rubber (Viton)

             Nitrile rubber, NBR

             Neoprene

      · Penetration time of glove material:

             The exact break trough time has to be found out by the manufacturer of the protective gloves and has to be observed.

      · Eye protection: Tightly sealed goggles

      · Body protection: Protective work clothing

             

Stability and reactivity

Chemical stability:

· Thermal decomposition / conditions to be avoided:

SADT (Self Accelerating Decomposition Temperature) is the lowest temperature at which self accelerating decomposition may occur with substance in the packaging as used in transport. A dangerous selfaccelerating decomposition reaction and, under certain circumstances, explosion or fire can be cause decomposition at and above the temperature. Contact with incompatible substances can cause decomposition at or below the SADT. No decomposition if used and stored according to specifications. To avoid ther al decomposition do not overheat.

Possibility of hazardous reactions: Self-accelerating decomposition at SADT.

Conditions to avoid: No further relevant information available.

Incompatible materials: Rapid decomposition by dirt, rust, chemicals in particular concentrated acids, alkalis and accelerators (e. g. heavy-metal compounds and amines).

Hazardous decomposition products: Hydrocarbons, carbondioxide and -monoxid. No hazardous decomposition products if used and stored according to specifications.

      Additional information: Emergency procedures will vary depending on conditions. The customer should have an emergency response plane in place.

Disposal considerations

Waste treatment methods:

      · Recommendation:

             After diluting with a suitable desentisation agent to 10 %, the solution must be supplied to a special treatment (e. g. thermal utilization) under observance of all official regulations.

      · Waste disposal key:

             Please contact your hazardous waste disposers to assign the right EWC-(European waste catalog)-number.

Uncleaned packaging:

      · Recommendation: This material and its container must be disposed of as hazardous waste.
