About Us

About UsThe National National Health Laboratory Service's (NHLS) Institute for Occupational Health (NIOH), is recognised internationally for excellence in research, service and training to support occupational health services not only in South Africa but also in Southern Africa through its extensive outreach activities and collaborations.

The NIOH has made great strides in terms of its overall objectives, particularly around quality, and continues to provide training, service and research assistance to a wide range of local, provincial and central government stakeholders.

Who are we

The National Institute for Occupational Health (NIOH) has existed in various forms since the 1950s. The South African Institute for Medical Research (SAIMR) was founded to study diseases in mine workers, particularly pneumoconiosis and tuberculosis. The delayed onset of these occupational diseases was recognised in relation to compensation and South Africa introduced post mortem examination of cardiorespiratory organs of all deceased miners and ex-miners.


Our Divisions

The NIOH consists of 6 key divisions: Occupational Medicine and Epidemiology; Occupational Hygiene; Pathology; Toxicology and Analytical Services; National Cancer Registry and Cytology. Each division has a specific focus and provides services and training to stakeholders, clients and students. The divisions often collaborate on research projects relevant to the health of the South African workforce.


Who we work with

The NIOH works closely with many different national and international organisations to increase understanding, raise awareness and standards in occupational health and to develop partnership projects. The institute's main objective is the promotion of occupational health and safety and the development of human resources in the SADC Region, through international training and outreach programmes.
