Air Sampling and Fibre Counting

This course is designed to provide students with theoretical and practical knowledge for air sampling and fibre counting and covers the BOHS P403 syllabus. Students are taught how to analyse air samples and report the results correctly, and will need to pass both a written theory and a practical exam to obtain this qualification. The course duration is two days including theory, practical work and the exams.

P403 Training CourseCandidates are expected to be aware of the contents of HSG 248 Asbestos: The Analysts Guide, and in particular Appendix 1 ‘Fibres in air: sampling and evaluation of by phase contrast microscopy’. Candidates will preferably have prior experience of analysing fibre count samples and may already be participating in a quality control scheme.
