Welcome to IOHA

The International Occupational Hygiene Association (IOHA) represents the global community of occupational hygienists.  IOHA is an association of occupational hygiene organisations from across the world, all of which are dedicated to the discipline and application of the inherent principles of occupational hygiene.

The Occupational Hygiene Training Association (OHTA) was formed to promote better standards of occupational hygiene practice throughout the world and provide training in the discipline. IOHA supports OHTA and are working together to provide formal recognition of the qualifications delivered by the OHTA training programmes.
