International Occupational Hygiene Association (IOHA)

IOHA is an association of occupational hygiene organisations from across the world, dedicated to the discipline and application of the inherent principles of occupational hygiene. IOHA was created in 1987 to represents the global community of occupational hygienists. Since its formation, it has grown to 38 member organisations, representing over 20,000 occupational hygienists worldwide.

What they do

IOHA’s mission is to enhance the international network of occupational hygiene associations that promotes, develops and improves occupational hygiene worldwide, providing a safe and healthy working environment for all. The strategic goals are: 

1. Promote occupational hygiene
2. Improve occupational hygiene capabilities and practice
3. Effective networking and knowledge management
4. Robust governance

IOHA provides an international voice of the occupational hygiene profession through its recognition as a non-governmental organisation (NGO) by both the International Labour Organisation (ILO) and the World Health Organisation (WHO). IOHA also co-operates with the work of other international organisations such as the International Commission on Occupational Health (ICOH) and the International Ergonomics Association (IEA).

IOHA promotes respect for occupational hygiene certification programmes through the work of its National Accreditation Recognition (NAR) Committee, which recognises those certification programmes that meet its criteria for excellence in occupational hygiene.

How we work together

We have been a member of IOHA since IOHA was established in 1987. Each member association designates one person to serve on the IOHA Board. The current BOHS representative is Dave Marsh.  

The NAR Committee has recognised the BOHS Diploma of Professional Competence in Occupational Hygiene (DipOH) certification programme, and our current representative on the NAR Committee is David O’Malley.
