The ergonomics regulations : the role of the health professions

Abstract

Ergonomics is the scientific discipline concerned with customising workplace conditions and job demands to fit the capabilities, limitations, and needs of the workforce. It is a multidisciplinary field, synthesising principles from diverse areas such as human factors engineering, industrial engineering, physiology, psychology, industrial design, biomechanics, kinesiology, occupational safety, and occupational health. The Ergonomics Regulations compel employers to undertake ergonomic risk assessments, implement control measures, provide training, and conduct medical surveillance to protect employees from ergonomic-related disorders. The Regulations mandate that ergonomic risk assessments be performed by a ‘competent person’, yet stop short of defining explicit criteria for competence. This has led to some confusion regarding the involvement of health professionals in ergonomic risk assessment and raises the question, ‘Do health professionals comply with the legal definition of competence for this task?’ This paper uses a systems ergonomics approach to highlight the diverse and complex risk factors that human workers bring to the workplace. The authors argue that qualified health professionals are best positioned to identify and manage high-risk motor, sensory, psychosocial, cognitive, and behavioural human factors, and are therefore indispensable in the ergonomic risk assessment process.
