The uncured materials must not, for instance, beallowed to come into contact with foodstuffs or food utensils, and measures should be taken to prevent theuncured materials from coming in contact with the skin, since people with particularly sensitive skin may beaffected. The wearing of impervious rubber or plastic gloves will normally be necessary; likewise the use ofeye protection. The skin should be thoroughly cleansed at the end of each working period by washing withsoap and warm water. The use of solvents is to be avoided. Disposable paper - not cloth towels - should beused to dry the skin. Adequate ventilation of the working area is recommended. These precautions aredescribed in greater detail in Ciba Specialty Chemicals publication No. 24264/3/e Hygienic precautions forhandling plastics products of Ciba Specialty Chemicals and in the Ciba Specialty Chemicals Material SafetyData sheets for the individual products. These publications are available on request and should be referredto for fuller information.Ciba SpecialtyChemicalsPerformancePolymersDuxford, CambridgeEngland CB2 4QATel:+44 (0)1223 832121Fax:+44(0)1223 493322All recommendations for the use of our products, whether given by us in writing, verbally, or to be implied from theresults of tests carried out by us, are based on the current state of our knowledge.
