Proposition de méthode de prélèvement des poussières dans l'industrie de l'amiante (French)

This French-language document was not a research study but a proposed method for sampling airborne dust and measuring dust levels in asbestos-industry premises. It covered premises named in recommendations on asbestos-industry working conditions by the Normandy regional Social Security fund (reference C. 320, which the text dates 'nov. 65'). Air was drawn through a vertical filter set at a specified height above the floor, using an ARM sampler or another device used by the fund's inspection services. The indicative sampling time was 8 minutes. Dust was to be examined by the IRCHA laboratory's technique and reported by mass (mg/m3) and as particle counts per litre of air. Workstation dust, measured where the worker usually stands, was the arithmetic mean of at least 3 samples, dropping a result far from the others when the spread was too large. Measuring dust for a whole room was considered meaningful only where asbestos work was its main activity. The document strongly urged companies to work with the fund's prevention services on a medium- and long-term plan, giving particular weight to workstations.
