Founded in 1945 in the UK, IOSH has become a trusted authority in occupational health and safety, offering professional development, training, and advocacy for safer working environments.

What Does IOSH Stand For?

IOSH stands for the Institution of Occupational Safety and Health. It is a chartered body and membership organisation dedicated to promoting excellence in health and safety practices across all industries.

Each year, over 100,000 professionals pursue IOSH qualifications to enhance their knowledge, improve workplace safety, and meet compliance standards.

What is IOSH Training?

IOSH provides health and safety training courses for all levels. IOSH training courses are designed to support professionals at every level, from entry-level workers to senior managers. These courses combine theoretical knowledge with practical application, helping learners identify risks, implement safety procedures, and foster a culture of care.

Key learning outcomes include:

• Risk identification and assessment
• Workplace hazard recognition (biological, environmental, physical)
• Implementation of safety procedures such as inspections, signage, and emergency drills

At a high level, learners will be asked to identify risks in a similar way to the hazard perception segment of a driving test. In this case, however, the dangers will be biological, environmental or physical in nature. They'll be asked to assess the potential health and safety challenges in their workplace against an outlined scoring system. IOSH courses also provide information on procedures to help keep those around them safe, all of which contribute to the ongoing protection of the workforce. Key learning outcomes include:

Upon completion, learners receive an internationally recognised IOSH certificate. The IOSH Code of Conduct is considered to be the industry's bible when it comes to facilitating a ‘safer and healthier world of work’.
