The British Occupational Hygiene Society (BOHS) is a science-based, charitable body that provides information, expertise and guidance in the recognition, control and management of workplace health risks. BOHS was founded in 1953: it is the only professional society representing qualified occupational hygienists in the UK, and has over 1800 members in 57 countries. BOHS is the only occupational hygiene organisation to be awarded a Royal Charter: this was granted in April 2013 in recognition of BOHS’ unique and pre-eminent role as the leading authority in occupational disease prevention.
