Our International Partners
BOHS is a founding member of both the International Occupational Hygiene Association (IOHA) and the Occupational Hygiene Training Association (OHTA).
Established in 1987, IOHA provides an international voice for the occupational hygiene profession and has close working links with the World Health Organization (WHO) and the International Labour Organization (ILO). The IOHA network is made up of many national occupational hygiene associations.
OHTA was established as an international training scheme and qualifications framework which provides free, high-quality, training materials in several languages and the infrastructure for low-cost training courses, as part of an internationally recognised programme of study.
