To reduce the professional risks linked to exposure in the galvanic industries, in this Regional project, we gave particular attention to the analysis of the documents which evaluated both chemical and cancerogenous risk. Under Legislative Decree n. 626/1994 we examined the documents of 45 different companies. In many cases, we found a poor technical-scientific level. These documents were practically unusable and moreover were difficult to interpret for workers in this field. Motivations are probably to lead back to the complexity of the problem and to the insufficient sensibility of the responsible of the prevention in respect of risks with long-term effect, which are not immediately connected to the exposure.
