Institution of Occupational Safety and Health (IOSH)

Institution of Occupational Safety and Health logoFounded in 1945, the Institution of Occupational Safety and Health (IOSH) is the largest body for individual health and safety professionals in the world, with around 43,000 members in over 100 countries, including over 13,000 Chartered Safety and Health Practitioners. We have 33 branches worldwide and 17 special-interest groups and our members work both in-house and also as external advisers, at strategic and operational levels, across all employment sectors.

Incorporated by Royal Charter, IOSH is a registered charity, and an ILO international NGO and CIS collaborating centre. The IOSH vision is:

“A world of work which is safe, healthy and sustainable”

We set professional standards and support and develop our members, providing initial and continuing professional development programmes. We accredit qualifications for membership, provide guidance / resources and run courses / events to help members in their work.

We’re the voice of the profession, and lobby governments on policy and law – campaigning on issues affecting millions of working people. Regularly consulted by government and other bodies on draft legislation, codes of practice, guidance and international standards, IOSH is a founding member of UK, European and International professional body networks.

IOSH works with many organisations to raise awareness and standards and have developed training for schools and businesses.  Accredited trainers deliver health and safety awareness courses to all levels of the workforce, through a 1,600 licensed-trainer network - we issue around 100,000 certificates per year.

Area of occupational health

Health and safety practitioners are trained in occupational health, as well as safety, which are intrinsically linked. On health, practitioners can be involved in identifying occupational health hazards and assessing risk; advising on appropriate control measures; and assisting in implementing and monitoring effectiveness of controls. They may also be engaged in helping raise awareness and promoting prevention messages through the delivery of workplace training. Typically, their work will include issues covered by COSHH, as well as noise, vibration, MSDs and work-related stress. We are currently piloting a course designed to upskill practitioners in rehabilitation, return to work and reasonable adjustments.

Advice Line and Toolkits available 

We provide members with a triple enquiry-line (HS&E information, OSH and Employment law advice) and a number of freely available guides and on-line tools, including:

  • OH toolkit – covering MSDs, stress, inhalation hazards and skin disorders (
  • OSH research database – a searchable resource which helps users to identify what occupational safety and health research is being done / has been done by who and where in the UK (
  • Risk assessment routefinder – a tool for SMEs to identify their areas of vulnerability and manage their risks, including health and safety (
  • Safestartup – a resource for business start ups and small firms covering basic health, safety and environmental issues, with hazard information on 60 occupations (

We also provide two freely downloadable guides: “A healthy return – good practice guide on rehabilitating people at work” and “Working well – guidance on promoting health and wellbeing at work”.
