This Professional Certificate covers Total Workplace Safety and Health (Total WSH) as the Singapore framework to promote worker safety, occupational health, and wellness. It is an evolution of the traditional view that worker health is only about safety at the workplace. The framework encourages companies to view worker health holistically and provides guidance on the assessment of worker’s Total WSH needs, as well as the implementation of intervention or preventive programmes. As Singapore continues its journey towards living with COVID-19, management of infectious diseases at the workplace will also be covered.
