What is the difference between Occupational Health and Occupational Safety

While presenting many Occupational Health and Safety (OHS) courses over the years. I have asked the delegates what is the difference between occupational health and occupational safety? Very few could give a reasonable answer. During the COVID-19 pandemic many OHS committees in the workplace collapsed and management took over with the guidance of the Government to manage the requirements in house. Very few companies had their OHS committees with the support of management, manage the directives from Government to manage the pandemic, who have the knowledge of the Occupational Health and Safety Act and the Regulation for Hazardous Biological Agents.
