Occupational Hygiene Qualification Courses

Our BOHS-accredited Occupational Hygiene courses provide professionals with in-depth training in key areas of workplace health risk assessment and control. Delivered in person by our own team of highly experienced occupational hygienists, these courses ensure hands-on learning and direct access to expert guidance throughout the training period.

We believe that face-to-face learning is the most effective way to develop professional Occupational Hygiene skills, which is why we primarily offer practical training with real equipment, in-depth discussions, and professional networking opportunities to provide an educational experience that goes beyond theory. However, we recognise that there may be circumstances where online learning is necessary, and where demand and circumstances require, online training can be provided by the same team of experienced occupational hygienists
