What IEH does

IEH (Institute of Ergonomics and Hygiene) Pte Ltd is a Singapore-headquartered private consultancy founded in 2012 that delivers integrated ergonomics, occupational hygiene, and workplace safety and health (WSH) solutions to industry, commerce, the public sector, and professional bodies. The firm operates three core service pillars — Ergonomics and Human Factors, Occupational Hygiene, and Workplace Safety and Health Services — supported by OHTA-approved training programs (W201, W501, W503, W505, W506, W507) and a content library of practical tools such as the Chemical Sampling/Analytical Methods database, the MAC Lifting Operations Assessment Guide, and Permissible Exposure Level references. Field capabilities rest on technical monitoring equipment (Casella brand air and noise monitoring instruments) and wearable solutions (EXO passive exoskeletons).

Revenue is generated through four streams: (1) on-site professional consultancy engagements billed as project-based services, (2) professional training and certification courses (with SkillsFuture Singapore credit eligibility and SDU/PDU continuing professional development credits), (3) hardware distribution of Casella instruments and EXO exoskeletons, and (4) the annual Ergonomics and Hygiene Conference and Exhibition in Singapore (inaugurated 2022, 4th edition in 2025) with delegate registration fees. GTM is enterprise field sales delivered directly to organizations, with a horizontal customer segmentation approach spanning multiple industries rather than a vertical specialization.

The firm has a Singapore HQ (11 Collyer Quay), a US LLC in Sacramento, California, and an Australian entity approved in 2022. It maintains an active presence in regional professional bodies including APOSHO, ANOH, and BOHS, and is led by Director Zephan Chan with Head of Ergonomics Phoebe Huang Xian. IEH operates with 11–50 employees, has no disclosed external funding, and is structured as a founder-led private company with no parent entity.
