The module concentrates on asbestos, but other fibres, e.g. Machine made mineral fibres, aramids, carbon etc., which are increasingly finding uses in industry are also covered.

Who is this course suitable for?

The course will benefit those working in asbestos consultancy as well as mainstream occupational hygiene, giving an understanding of the health risks associated with asbestos and other fibres as well as the means of evaluation & control.

Update from BOHS re M504 and M505

W504 and W505 have provided a pathway for learners to move onto the Certificate of Competence in Asbestos and the Certificate of Competence in Control respectively. Following a BOHS review and a review of the main pathways to these qualifications, as of 1st July 2025, candidates undertaking these modules will no longer be eligible to proceed to the relevant Certificate level solely on the basis of having undertaken these modules. This is because a significant amount of content and assessment which are pre-requisites for the certificates are not included in the M504 and M505 and expanding them to include this was not deemed feasible.
