Health surveillance involves systematic and regular health checks that enable the early identification of work-related ill health. This proactive approach helps in detecting adverse health effects before they become severe, allowing for timely intervention and treatment. Early detection is crucial in preventing long-term health issues and ensuring that employees remain fit and healthy.

Health and safety laws require health surveillance for certain health risks, especially when employees are exposed to hazards such as noise, vibration, and hazardous substances. Compliance with these regulations is essential to avoid legal penalties and ensure a safe working environment.

Health Surveillance provides a means to confirm whether risk control measures are working as intended and will identify any gaps or problems.

If performed regularly, the early signs of health problems can be detected before they can become noticeable and impact on the health of employees.
