There are eight grades of membership and four of these – Individual, Affiliate (for organisations or corporations), Retired and Student – are open to anyone within the relevant category. If you are interested in Retired membership, please contact us via membership@bohs.org.
The remaining four grades are Faculty grades and are restricted to members who have particular qualifications in occupational hygiene and related subjects. The different grades reflect various levels of knowledge, experience and contributions to the profession, from Licentiate (which entitles the member to use the post-nominal letters LFOH) to Member (MFOH) and Specialist Member (MFOH(S)), up to the highest grade of Fellow (FFOH). All Faculty members must participate in the Faculty’s Scheme for Continuing Professional Development (CPD) and have the right to call themselves a ‘Registered Occupational Hygienist’.
