Health Surveillance

Identification of Hazardous Exposures:

  • Understanding and recognizing potential workplace hazards such as chemicals, physical agents, biological agents, ergonomic factors, and psychosocial stressors.


Risk Assessment:

  • Evaluating the level and duration of exposure to identified hazards.

  • Assessing the potential health risks associated with exposure to specific substances or conditions.

Baseline Health Assessments:

  • Conducting pre-employment or pre-placement health assessments to establish a baseline of an individual's health before exposure to occupational hazards.

Regular Monitoring:

  • Implementing routine health check-ups and assessments during employment to monitor changes in health status.

  • Conducting periodic medical examinations based on the nature of the work and potential exposures.

Biological Monitoring:

  • Analyzing biological samples (e.g., blood, urine, or breath) to measure the levels of specific substances, providing insights into occupational exposures and potential health effects.

Medical Surveys and Questionnaires:

  • Administering health surveys or questionnaires to gather information on symptoms, lifestyle factors, and other relevant health indicators.

  • Using the collected data to identify patterns or trends that may indicate emerging health issues.


  • Maintaining accurate and confidential health records for each employee involved in health surveillance.

  • Documenting exposure levels, health assessments, and any recommended interventions or follow-up actions.

Feedback and Communication:

  • Providing feedback to both employers and employees on the results of health surveillance activities.

  • Offering recommendations for preventive measures, adjustments to working conditions, or additional training based on the findings.

Adaptation and Improvement:

  • Continuously reviewing and updating health surveillance programs in response to changes in workplace hazards, regulations, or advancements in medical knowledge.

  • Seeking input from employees and occupational health professionals to improve the effectiveness of health surveillance efforts.

"Health surveillance is a systematic and ongoing process of monitoring and assessing the health of individuals exposed to specific occupational hazards. The primary goal is to detect and prevent work-related illnesses or injuries by identifying early signs of adverse health effects. Health surveillance is an integral component of occupational health programs and is tailored to the nature of the workplace, the types of hazards present, and the specific risks associated with certain job roles.
