The "Institute" has a subsidiary, IOM Consulting Limited, which became fully independent in 1990 and now celebrates its 25th year within the IOM Group as an independent consultancy and also the commercial part of the IOM organization. It specializes in asbestos surveys and services, occupational hygiene services, nanotechnology safety, laboratory analysis and expert witness consulting services.

Coal and pneumoconiosis
The IOM was set up by Dr John Rogan, the chief medical officer of the NCB, who had initiated the Pneumoconiosis Field Research (PFR), persuaded the then chairman,
Lord Robens, to found a scientific institute to take over the running of this research. The original senior members of staff, under Rogan, were Henry Walton, deputy director and head of Environment Branch, Dr Michael Jacobsen, head of statistics and Dr David Muir, head of Medical Branch.
The early history of the IOM is inextricably bound up with the NCB and the PFR. The PFR had started in the early 1950s with the objective of determining how much and what types of
coal dust caused pneumoconiosis and what airborne dust concentrations should be maintained in order to prevent

The early work involved measuring dust exposure by counting the number of particles collected from the air by sampling devices. A substantial advance was achieved with the measurement of exposure by weighing the dust collected by MRE 113a respirable dust samplers, which were invented specifically for the research by Henry Walton and Robert Hamilton.
The first results from the PFR were reported in 1970 in the scientific journal ''

''. The research underpinned the recommendations for more stringent airborne dust standards in British coalmines and the PFR was ultimately used as the basis for many national dust standards around the world. IOM's research in coal mining continued until about 1990, with many important scientific papers on respiratory diseases amongst miners having been published. In 1985, an important association between risk of pathological

and dust exposure was demonstrated, leading ultimately to recognition of this disease as a quantifiable risk of coal mining. Recent analysis of the
mortality of a subset of the miners originally studied has found an association between the risk of lung cancer and quartz exposure, and raised mortality from chronic lung disease and

This research into risks from inhaling dusts remains an important part of the IOM's research. The
occupational exposure limits for
crystalline silica continue to be a major international concern and from its previous research IOM has been able to define an
exposure-response relationship for
crystalline silica with unusual precision. This work demonstrated the need for very low limits on exposure to airborne
crystalline silica because of the high risk of disease from even relatively brief exposures to high airborne concentrations.
IOM studies have defined the relationships between decreases in
lung function and dust concentrations amongst coal miners. These studies showed that dust control sufficient to prevent

Singapore office
On 3 September 2012, the IOM opened its new research, consulting and services business in Singapore. The IOM received support from the Economic Development Board of Singapore, UK Trade and Industry, and Scottish Development International in establishing its presence. The business focus will initially be on the safe use of nanomaterials in emerging technologies and occupational hygiene.
The key people in the team consist of Dr. Rob Aitken (managing director), Dr. Michael Riediker (director of SAFENANO) and Zephan Chan (head of occupational hygiene).
In June 2013, Singapore experienced the worst situation of haze problem in history. IOM Singapore have received several enquiries from their clients about good control measures to protect employees in workplaces. IOM Singapore developed a short note to assist Singapore employers to comply with the MOM recommendations by providing further information about good practice.
On the 5th of November 2021 it was announced that the office would become independent of IOM
and operate under the new identity of The Institute of Ergonomics and Hygiene. With Zephan Chan continuing to lead the business forward.
