title: [Acute silicosis in jewelry casting].
abstract: An accelerated silicosis case made our Occupational Health Unit focus on a pathology thought dropping so far to die out. Furthermore this event occurred in a manufacturing (lost-wax process in jewelry casting) regarded as a low-risk exposure. Besides unsuitable procedures, the user had underestimated the specific risk of that raw material (talcum-like powder at 60-80% silica crystalline level), commonly called "gypsum", inappropriately labelled since not yet adequately classified by the hazardous substances list. The widespreading of this manufacture in our area (Vicenza district) and the recent inclusion of Silica Crystalline in the Class 1 made by IARC (Jan 1997) have urged this Unit to take action in industrial hygiene investigations, instructions to the workers, mandatory directions to dealers concerning the proper hazard labelling for products containing silica crystalline and circulation of information among other Occupational Health Units involved.
