Prior Knowledge

Candidates 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.

Delegates will be required to provide their own counting kit and microscope. These can be hired if necessary.
