What is the Register of Occupational Hygiene Professionals?
The Register of Occupational Hygiene Professionals is administered by the Faculty of Occupational Hygiene, the Professional Standards Body for the British Occupational Hygiene Profession.
Whether you are employing someone to provide occupational hygiene advice in-house or have employed the services of a company, you need to check that the person giving you advice is competent to do so.
The Register enables you to check an individual’s level of expertise and to see whether they have been independently verified as meeting the requirements outlined in Regulation 7 of the Management of Health and Safety at Work Regulations 1999. If they are not on the Register, even if they are registered with another professional body, then there has not been an independent check of their training, experience and other attributes. It is your duty to ensure that you have undertaken appropriate due diligence to verify these matters yourself.
PSA Accreditation and the Quality Mark
In April 2024, the Register of Occupational Hygiene Professionals was officially accredited by the Professional Standards Authority for Health and Social Care (PSA), the UK’s regulator of registered health professionals. This accreditation demonstrates that the Register operates in the public interest, with robust standards, governance, and complaints handling consistent with the PSA’s Accredited Registers programme.
Being on a PSA-accredited register gives employers, duty holders and service users confidence that practitioners have been independently verified as meeting clear professional and ethical criteria. Qualified Occupational Hygienists (Provisional) and Occupational Hygiene Technicians on the Register are entitled to display the PSA Accredited Registers Quality Mark, a symbol of competence and commitment to ongoing professional standards.
