The main subject areas of the course are:

This course aims to provide candidates with an enhancement of their knowledge of occupational hygiene practice in relation to fibrous dusts. 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.

Course Timing

Duration: 5 days

Start time: 9am on course day, 1pm start for exam

Please see below for an update from BOHS regarding exam sittings/registration of candidates:

CHANGES TO BOHS EXAM REGISTRATION

BOHS have informed us of a change to delegate registration. They are now rolling out direct candidate registration. This removes the requirement for Candidate Information Forms to be completed. Candidates are asked to set up an account with BOHS and can then manage their personal data, in line with UK legal requirements.

To sit the exam, candidates must register with BOHS via a link to obtain a student ID. This Student ID is required for the exam. Failure to do this will mean the exam cannot be taken. AEC will send this link as well as instructions direct to you for all candidates wishing to sit the exam 10 days before the course start date.

All classroom courses will now have a remote exam set up by BOHS. You will need to bring a tablet or laptop with you to complete the exam.
