Occupational Hygiene is one of the welfare domains as included in the Act on well-being of workers in the performance of their work (04/08/1996) and the Royal Decree on the policy of well-being of workers at work (27/03/1998). The Internal and External services for Prevention and Protection at work should have prevention officers and experts with various skills, including occupational hygiene. Occupational hygienists collaborate with other prevention officers in a multidisciplinary way. 
In Belgium there are two training courses in which BSOH participates substantively. On the one hand, there is the Dutch specialist training course prevention officer occupational hygiene and on the other hand there is French specialist training course prevention officer occupational hygiene.Internationally it is worth taking a closer look at

Specialist training course prevention officer occupational hygiene (in collaboration with KU Leuven, Odisee and BSOH)
This Dutch course runs over two academic years and is mainly given at the KU Leuven Gasthuisberg campus. Odisee (service for further education) is organising the training course in cooperation with the KU Leuven, Unit Environment and Health and BSOH. The purpose of this training is to prepare students for the daily interpretation of a job as occupational hygienist, based on a thorough theoretical knowledge combined with practice-oriented applications. One learns to identify and assess chemical, physical and biological hazards at the workplace. For the different topics, a similar course structure is followed as much as possible, consisting of :

1. organisation, legislation and limit values;
2. agents with specific hazard properties;
3. toxicology and routes of exposure;
4. health effects;
5. measurement possibilities: external and internal dose;
6. preventive measures

The training aims that at the end of the course, one has the required knowledge and skills to take necessary preventive measures in specific work situations, leading to better hygiene and health at work. This is done in consultation with a multidisciplinary team of prevention officers and safety experts (engineers, occupational physicians, ergonomists, psychologists and environmentalists). This training is meant for all interested parties for prevention and well-being of workers in companies and organisations.
The program is in accordance with the prescribed requirements, as specified in the Royal Decree on the expertises of the prevention officers of the external services for prevention and protection at work (5/12/2003). Prevention officers that are experts in occupational hygiene should have successfully completed the specialisation module “Occupational Hygiene”.

The Occupational Hygiene Training Association (OHTA) was founded to promote better standards throughout the world.  OHTA is developing training material and makes it freely available for use by and for students and training providers.  OHTA also promotes an international qualification and certification framework so that all occupational hygienists are trained at a consistent, high standard approved by all participating countries. The organisers of the training course will check the possibility for the Specialist training course to join the framework, as a big part of the work has already been done, in view of the participation of the KU Leuven to the European Credit Transfer System (ECTS).
