Asbestos and other fibers

This free course is meant to enlarge a student’s knowledge of occupational hygiene practice in relation to fibrous dust. The course concentrates on asbestos, but other fibers are also covered. These fibers, such as machine made mineral fibers (MMMF), aramid fibers (Kevlar, Twaron), polyolefin fibers, and carbon fibers, are increasingly used in industry. The course provides understanding of the health risks associated with asbestos and other fibers, and gives also insight into methods of evaluation and control. Besides, practical skills for safely taking samples from bulk materials and for assessing fiber concentrations in the atmosphere are covered.

The material is appropriate for students, who have basic knowledge of biology and chemistry. For teachers, a guideline is added. The course consists of ready-to-use material, that can be downloaded free of charge, printed and displayed. No online interaction is necessary.
