When should employees undergo medical examinations? Are these examinations compulsory? What is a Certificate of Fitness, and how do employers know which assessments their employees need?
Understanding the basics can help businesses make informed decisions, identify potential workplace health risks and manage their occupational health responsibilities more effectively.
In this guide, First Choice Occupational Health & Mobile answers eight common questions to help employers better understand occupational health and the role it plays in their workplace.
1. What Is Occupational Health?
Occupational health focuses on the relationship between people’s health and their work. It aims to protect employees from work-related health risks while supporting their ability to perform their duties safely.
This involves more than conducting medical examinations. Occupational health may include identifying workplace hazards, assessing health risks, monitoring employees’ health where necessary and helping employers understand the relationship between workplace exposures and potential health effects.
For example, employees working in noisy environments may be at risk of hearing damage, while those exposed to certain chemicals or airborne substances may face respiratory or other health risks.
Understanding these risks helps employers determine which preventive measures and health assessments may be appropriate.
2. Why Do Employees Need Occupational Medicals?
Occupational medicals help assess an employee’s health in relation to their work and the risks associated with their duties.
There are two important considerations:
- Protecting employee health: Could workplace exposures cause or contribute to adverse health effects?
- Assessing fitness for work: Could a health concern affect the employee’s ability to perform particular duties safely?
For example, hearing assessments may help identify changes in hearing among employees exposed to occupational noise. Depending on the work and relevant risks, other employees may require respiratory assessments, vision screening or additional medical examinations.
Occupational medicals can also help identify health concerns that may require further investigation or workplace intervention.
However, medical examinations are only one part of an effective occupational health programme. They do not replace workplace risk assessments, exposure controls, appropriate training or personal protective equipment.
3. Are Occupational Medicals Compulsory?
Occupational medical examinations are required in certain circumstances under South African legislation. The specific requirements depend on the nature of the work, the hazards involved and the legislation or regulations that apply.
For example, particular requirements may apply to mining operations, employees exposed to certain hazardous substances and other work involving prescribed health surveillance.
This means that employers should not assume that every employee requires the same medical examination or that a standard medical package automatically satisfies all applicable requirements.
The starting point is to understand the work employees perform, identify the associated risks and establish which medical assessments are required.
Where there is uncertainty, an occupational health professional can help clarify the appropriate assessments and surveillance arrangements.
4. What Types of Occupational Medicals Are There?
Different medical examinations serve different purposes. The appropriate assessment depends on the employee’s role, workplace exposures and the reason for the examination.
| Type of medical | What is it for? |
| Entry or pre-placement medical | Assesses relevant health considerations before an employee starts a particular work, where required. |
| Periodic medical | Monitors employee health over time in relation to relevant workplace risks. |
| Transfer medical | Considers health requirements when an employee moves to different duties or a different work environment, where appropriate. |
| Exit medical | Assesses and documents relevant health findings when employment ends, where required. |
| Return-to-work assessment | May help establish whether an employee can safely resume specific duties after an absence or change in health. |
| PrDP medical | Assesses medical fitness for the applicable professional driving permit requirements. |
Not every employee will need every type of examination. The applicable legislation, the employee’s duties and the circumstances determine which assessments are appropriate.
Understanding these differences helps employers plan their occupational health requirements instead of treating every medical examination as interchangeable.
5. How Often Should Employees Undergo Occupational Medicals?
There is no single examination interval that applies to every employee and every workplace.
The frequency of occupational medicals may be prescribed by specific legislation or regulations, or determined by the applicable risk assessment and the advice of an appropriately qualified occupational health professional.
Some employees may require annual examinations, while others may follow different intervals depending on their work and the requirements that apply to them.
Employers should therefore avoid relying on a blanket annual or biennial schedule without first confirming the relevant requirements.
It is also important to review occupational health arrangements when job duties, workplace exposures or relevant risks change. A change in circumstances may mean that existing assessments or monitoring arrangements need to be reconsidered.
6. What Happens During an Occupational Medical?
An occupational medical is tailored to the employee’s work and the health risks that need to be assessed.
Depending on the requirements, an examination may include:
- A medical and occupational history.
- A physical examination.
- Vision screening.
- Hearing assessments.
- Lung-function testing.
- Other clinical examinations or tests relevant to the employee’s work and identified risks.
For example, an employee exposed to excessive workplace noise may require hearing assessments, while an employee exposed to certain respiratory hazards may need appropriate respiratory testing.
These tests are not necessarily required for every employee. The purpose is to select assessments that are relevant to the work and the risks involved.
Employers can help the process by providing accurate job descriptions, information about workplace hazards and relevant risk assessment documentation before medicals are booked.
7. What Is a Certificate of Fitness, and Is It the Same as a “Red Ticket”?
The term “Red Ticket” is still used in some workplaces, particularly where it has historically referred to a certificate associated with medical fitness.
In occupational health, a Certificate of Fitness generally communicates the outcome of an assessment in relation to specified work or duties, subject to the applicable regulatory framework.
Depending on the circumstances, an employee may be found fit for the relevant duties, fit subject to restrictions or in need of further assessment.
A restriction does not necessarily mean that an employee cannot work at all. It may mean that certain tasks or exposures should be avoided or that certain conditions need to be met.
Employers should understand the meaning of the certificate issued for their industry and follow any applicable requirements concerning fitness, restrictions and the employee’s duties.
A Certificate of Fitness is not a guarantee that an employee will never develop a health problem or experience a workplace injury. It is one component of a broader approach to managing occupational health and safety.
8. What Should Employers Prepare Before Booking Occupational Medicals?
Good preparation helps ensure that employees receive appropriate assessments and that important workplace risks are not overlooked.
Before arranging occupational medicals, employers should consider the following:
Job descriptions and duties: Understand what each employee does, including any safety-sensitive tasks or specific physical requirements.
Hazard Identification and Risk Assessment (HIRA): Identify the hazards employees may encounter and assess the associated risks.
Occupational Risk Exposure Profile (OREP): Where applicable, use relevant exposure information to help establish which assessments are needed for specific roles.
Applicable requirements: Confirm which medical examinations, monitoring intervals and certificates are required for the work concerned.
Employee information and scheduling: Prepare accurate employee details and arrange appointments in a way that minimises unnecessary operational disruption.
Previous medical information: Where relevant and lawfully accessible, ensure that appropriate follow-up takes account of previous findings or restrictions.
When employers understand their workplace risks before booking medicals, it becomes easier to select appropriate assessments and establish a more organised occupational health programme.
Why Getting the Basics Right Matters
Occupational health is not simply about arranging medical examinations or keeping certificates on file. It is about understanding how work can affect employee health and taking appropriate steps to manage those risks.
When medicals are planned according to workplace requirements, employers can support the early identification
of potential health concerns, respond appropriately to findings and review workplace controls where necessary.
Neglecting applicable occupational health requirements may expose employees to preventable health risks and businesses to operational disruption, compliance difficulties and potential legal consequences.
The appropriate approach is to understand the risks, confirm the applicable requirements, arrange suitable assessments and act responsibly on the findings.
