HANDLINGPRECAUTIONSCautionOur products are generally quite harmless to handle provided that certainprecautions normally taken when handling chemicals are observed. The uncuredmaterials must not, for instance, be allowed to come into contact with foodstuffs orfood utensils, and measures should be taken to prevent the uncured materials fromcoming in contact with the skin, since people with particularly sensitive skin may beaffected. The wearing of impervious rubber or plastic gloves will normally benecessary; likewise the use of eye protection. The skin should be thoroughlycleansed at the end of each working period by washing with soap and warm water.The use of solvents is to be avoided. Disposable paper - not cloth towels - shouldbe used to dry the skin. Adequate ventilation of the working area is recommended.These precautions are described in greater detail in the Material Safety Datasheets for the individual products and should be referred to for fuller information.IMPORTANT LEGAL NOTICEHuntsman Advanced Materials warrants only that its products meet the specifications agreed with the user.
