How do you become an Occupational Hygienist

Occupational hygienists come from varied backgrounds. They may be industrial chemists, engineers, environmental scientists or other professionals, all of whom have chosen to apply their skills to protect the health of workers. Occupational hygiene is multidisciplinary so its practitioners must acquire a broad and solid foundation of knowledge across a wide range of disciplines. Common to all practitioners is a core of knowledge that can be described as "occupational hygiene" and a strategic approach to managing health hazards at work.

Although occupational hygienists come to the profession through various pathways, the first step is to complete a degree or diploma in Science or Engineering with a major in a quantitative science acceptable to the AIOH. Typically, occupational hygienists have one or more postgraduate qualifications in occupational hygiene as a specialised discipline. A full list of accredited degrees can be found here.

In order to meet the requirements for professional grades of membership, and therefore be considered an occupational hygienist, a satisfactory level of relevant experience and professional competence must be demonstrated to the AIOH. Part of this will involve demonstrating the number of years’ experience of working in the field of occupational hygiene.
