BOHS is a charity that makes a distinct and valuable contribution to preventing ill health. We bring science, technology and forethought to bear on the workplace conditions that can gradually undermine health. We are a learned and professional society that through research and education helps to protect individuals and benefit the public. We are committed to raising awareness of these complex health issues. BOHS publishes the world-renowned, scientific, peer-reviewed journal, Annals of Work Exposures and Health, and we are the only professional society representing qualified occupational hygienists in the UK. Through our Faculty of Occupational Hygiene, we set professional standards and are the only UK examining board for qualifications in occupational hygiene. What is occupational hygiene? Occupational hygienists get involved at the interface of people and their workplaces. They use science and engineering to prevent ill health caused by the work environment - specialising in the assessment and control of risks to health from workplace exposure to hazards. Hygienists help employers and employees to understand these risks and to minimise or eliminate them.
