What type of Testing Is Needed?

Apex provides medical surveillance programs specific to the unique risks and exposures of your organization. From hearing and respiratory surveillance, vision testing to blood testing, we assist you in demonstrating your commitment to employee health.  Here are a few types of occupational health risks we can help you monitor:

Chemical Exposure

Employees who work with or are exposed to designated substances such as acrylonitrile, arsenic, asbestos, benzene, coke oven emissions, ethylene oxide, isocyanates, lead, mercury, silica and vinyl chloride are required to be part of a control program that may have medical examinations and clinical testing included. We ensure your employees are tested on the required schedule as part of the Ontario Occupational Health and Safety Act and corresponding Regulations.


Many workplace activities can generate various types of dust particles, which, when inhaled, may pose health risks to workers. Apex provides respiratory protection programs, medical surveillance and mask fit testing to ensure your business reduces exposure to chemical and biological agents.

Noise Exposure

Workers in loud environments such as manufacturing plants or construction sites may need medical surveillance for noise exposure such as hearing testing as part of a pre-placement medical assessments and on-going annual medical surveillance.


Employees using vibrating tools or machinery on a regular basis may lead to hand-arm vibration syndrome (HAVS). Our ergonomic and functional services assist in identifying and reducing the risk associated with vibration.

Vision Exposure

Employees working with intense light sources or in environments with glare, such as welders, can lead to vision impairments or eye strain. Monitor your team members exposure with pre-placement medical assessments and on-going annual medical surveillance.

Workplace Impairment

Impairment commonly refers to an altered state of physical and/or mental functioning. In a workplace context, someone who is impaired may have difficulty completing tasks in a safe manner and may put themselves, their coworkers and the public in danger. Apex assists with providing guidance on when and how testing can be used to identify workplace impairment.

Assessing Your Need for a medical surveillance program

Steps to review Compliance

In Ontario, it’s important that your business take the following steps to meet the requirements of a Medical Surveillance program:  

  1. Review Legislation and Regulations: Begin by familiarizing yourself with Ontario’s occupational health and safety legislation, including the Occupational Health and Safety Act (OHSA) and its regulations. Pay particular attention to any requirements or guidelines related to medical surveillance programs for specific hazards that your business may utilize or industries you work in.  
  2. Identify Workplace Hazards: Conduct a comprehensive assessment of workplace hazards, including chemical exposures, physical hazards, biological agents, and ergonomic risks. Consider factors such as the nature of the work, potential health effects of exposures, and the likelihood of exposure occurring.
  3. Assess Health Risks: Evaluate the potential health risks associated with identified workplace hazards. Consider the known health effects of exposure, including acute and chronic conditions, as well as any specific health concerns related to vulnerable populations or individuals with pre-existing conditions.
  4. Consult with Health and Safety Professionals: Seek input from qualified health and safety professionals, such as occupational hygienists, industrial hygienists, and occupational health physicians. They can provide expertise in assessing workplace hazards, evaluating health risks, and determining the need for medical surveillance based on industry best practices and regulatory requirements.
  5. Evaluate Existing Control Measures: Review existing control measures implemented to mitigate workplace hazards. Determine whether these measures adequately control exposure risks or if additional measures, including medical surveillance, are necessary to further protect employee health.
  6. Develop a Medical Surveillance Program: If the assessment indicates a need for medical surveillance, develop a comprehensive program in consultation with health and safety professionals. Define the objectives of the program, including the specific hazards or exposures to be monitored, the frequency and type of medical examinations required, and the procedures for employee participation and confidentiality. Ensure that the program complies with relevant legislation and addresses the unique needs of your workplace.
By following these steps, you can systematically assess the need for a medical surveillance program and take the appropriate measures to protect the health and safety of your employees.  As Occupational Health Medical Surveillance Program experts, Apex can assist you with one or all the steps above.  Reach out and begin the steps to transform your business.
