Occupational hygienists identify, assess and control workplace health hazards, such as dust, bacteria, noise and stress.

To work in occupational hygienist jobs, a degree in a subject such as life science, physical science or environmental health is essential. While the role is open to graduates from a range of disciplines, employers tend to seek those with a sound knowledge of chemistry. A postgraduate qualification in occupational hygiene will aid those wishing to enter into the profession and can improve career prospects for those already employed in occupational hygienist jobs.

In addition to university education, candidates for occupational hygienist roles require evidence of interest in improving the health and wellbeing of others, good communication skills, an ability to negotiate with others, a persistent and resilient approach, good decision-making skills, and an ability to prioritise tasks.

Typical employers of occupational hygienists include large industrial companies, occupational hygiene consultancies, government agencies, environmental monitoring companies, the NHS, and academic institutions. Larger employers of occupational hygienists provide in-house training to their new recruits. However, consultancies tend to only take on staff with a high level of experience.

Occupational hygienists in employment in the NHS may earn between £21,000 and £34,000 a year. Promotion opportunities for occupational hygienists depend on the nature of the company for which they work. With experience, it is possible for employees to move into management roles.
