Medical surveillance involves regularly monitoring workers’ health to identify any effects related to workplace hazards. It’s goal is to help maintain a safe, healthy work environment in compliance with OSHA standards, while also assessing how job conditions may impact employee well-being.
Fit for Duty
To ensure employees are physically able to perform their job tasks, the company should conduct pre-employment physicals. A physical should also take place when there are changes to job assignments or work environments. Medical surveillance should be conducted annually or sooner at the employer’s discretion, and should include a post-employment examination.
The employer should document prescribed medications, as well as over-the-counter medications, such as allergy, cold, and flu medications that could impair the worker’s ability to perform their tasks.
Medical Exam
Medical surveillance includes several key components, with specific tests varying based on the hazards present in the workplace. However, the overall process remains consistent. A comprehensive medical exam should include a review of the employee’s work and medical history, a physical examination, and any additional tests relevant to the identified risks.
Certification Examination
Certification examinations establish an employee as a qualified worker for a specific duty that could be hazardous or safety sensitive. The health provider conducting the examination will be familiar with the qualifying metrics and results that would disqualify them from certification.
Employee Rights
If an employee is injured or feeling ill while working, as a result of being on the job site, they can undergo a medical evaluation to determine if medical issues are present. This should be offered at no cost to the employee.
Results
The data collected should be private and evaluated to determine if medical treatment is appropriate. Depending on the results, the employee may:
- Be able to perform any assigned tasks
- Have medical conditions that require a job transfer
- Need new fit-tested Personal Protective Equipment
- Require medications or treatment
- Or, have a chronic condition that worsens overtime, to the point where they are no longer fit for duty

Conclusion
Medical surveillance is more than just a regulatory requirement—it’s a proactive approach to protecting worker health and safety. By identifying potential health risks early, employers can prevent serious illnesses, reduce workplace incidents, and promote a culture of care and responsibility.
