Title Exposure to asbestos fibres during vehicle maintenance
Original title Exposición a fibras de amianto en operaciones de mantenimiento de vehículos [in Spanish]
Bibliographic information 2002, No.21, p.11-21. Illus. 14 ref.
Abstract During vehicle maintenance work, workers are exposed to asbestos fibres (chrysotile) when working on brakes or the clutch. The objective of this study was to identify the nature of the fibres that were present in friction elements of vehicles and to determine the level of exposure of workers to asbestos during operations giving rise to a liberation of asbestos fibres in workplace air. An analysis of friction materials and fibre types was carried out, and air samples were collected from 24 workshops. Results confirm the established tend towards the substitution of asbestos. Chrysotile was present in 30% of the clutch disk and 41% of brake shoe samples analysed. 57% of the air samples contained either no asbestos or negligible concentrations. When asbestos fibres were present, their concentrations were below legal limits.
