Chemical resistence of latex gloves [Efficacia protettiva dei guanti di latice nei confronti degli agenti chimici]
No full textDermal chemical risk is represented by the chemicals with irritant, caustic and sensitization properties or that can produce toxic effects after penetration through the skin. During the last few years the interest for the effective protecting ability of gloves progressively is increased in parallel with their use. Penetration of chemicals through the protecting material does not always turn out visible. That has led to the development of test standardizes. In 1989 the EC adopted two Directives in the field of the characteristics of protection devices defining certification procedures (89/686/EEC) and characteristics demanded for the use of protection devices at the workplace (89/656/EEC). When the European Standards are accepted from the CEN they exist in rough draft shape (prEN), losing the prefixed one pr- when they are approved by all the EC member Countries. A number of ENfor protection gloves have been proposed by CEN/TC162 regarding methods for testing the resistance to penetration/permeation of chemicals and other characteristics. However in these protocols some limitations were found, since not necessarily they represent the real using conditions. In general an ideal protecting material against the chemicals does not exist because what is effective to a specific compound does not effectively protect from an other. Latex is not commonly considered a very chemical resistant material and therefore its use in such sense is limited. However the low cost and the spread of latex gloves in particular in Public Health often make them easy available at workplace and therefore used in several situations
Cutanuous risk from metals [Il rischio cutaneo da metalli]
No full textMETALS AND SKIN. The importance of metals as potential human health hazard is increasing. They are present in the working places and in the general environment. Moreover the potential exposure of large segments of the population to metal containing compounds in personal-care products should be considered. Metals can cause different adverse effects upon exposure to the skin such as irritant and allergic contact dermatitis, urticaria, granuloma and systemic toxic effects.
Despite the dimension of the problem there is a lack of data relevant for dermal risk assessment. Results on the biological effects of metals, in particular their penetrating ability and action on the skin, are widely disseminated in literature.
Moreover they are obtained using experimental conditions very different between each other, so comparison of results is difficult. A large part of the reported data on in vivo/in vitro percutaneous penetration of various metals such as Nickel, Chrome and Cobalt was published in the ’60s and ’70s and the results were not obtained using up-to dated methods

Chemical risk assessment in the leather goods producers: A comparison of the results obtained by measurements air concentration and algoritm archi.mede [Valutazione del rischio mchimico nel settore pellettiero:confronto dei risultati ottenuti con sistemi di campionamento attivo e algoritmo ARChiMEDE]
No full textThe Italian legislation on chemical agents has undergone significant changes. The aim of the study was to compare the results obatainedfrom an environmental investigation and the use of the ARChi.MEDE model. The results of the survey were treated with the UNI EN 689/1997 that showed an acceptable result, while according to the use A.R.Chi.M.E.D.E. a significant risk was obtained. Actually the mathematical model assess workers exposure without considering in the calculation the specific preventive measures (personal protective equipment, training, uptake of pollutants at the source) as contemplated by law. So the mathematical model showed the need of preventive measures in the studied work place. © PI-ME, Pavia 2011
