RESUMEN
The analysis of professional diseases denounced from hairdressers in Italy and in Tuscany shows among these workers a reduction of some "typical" work related diseases, like dermatitis, asthma, etc. and a raise of upper limbs disorders. The upper limbs risk assessment process is very tough for the hairdresser's activity, because the working cycle includes different tasks (shampoo, cut, dyeing, etc.) and their combination in a working day is related to customers requests. The job illustrates the first results of a project started last year from the Tuscany Technical Advisory Department for Risk Assessment and. Prevention (CONTARP) of the Italian Workers' Compensation Authority (INAIL) and PISLL "G. Pieraccini" - ASL 10 of Florence. Through a study conducted with the OCRA Check List method on a sample constituted by 12 employees of five shops of the Florentine territory, we have arrived to a job-exposure matrix that allows to draw an index of exposure to the specific risk for every task, keeping in mind the contributions of the single repetitive assignment performed by the operator during the working day.
