Emergency Service Workers

Emergency Service Workers (ESW) are at an increased risk of exposure to infectious diseases. The risk of exposure can be reduced with the implementation of proper health and safety programs designed to protect workers from infectious diseases. The role of the Designated Officer in such programs is essential.

As part of the Health Unit’s role in supporting our area Designated Officers, the resources listed below are available to you. These resources will assist the Designated Officer in assessing and managing exposures to infectious diseases to protect the health of the workers and to prevent further spread of infectious organisms. The Health Unit will not gather information from the ESW who was exposed; this is the role of the Designated Officer/supervisor.


Mandatory Blood Testing Act

To qualify, the exposed person (referred to as the applicant) must apply to the Medical Officers of Health at the local Public Health Unit where the source resides.

The applicant must have come into contact with a bodily substance from the source (referred to as the respondent) in any of the following circumstances:

  • As a results of being a victim of crime,
  • While providing emergency health services or emergency first aid to the person, or
  • In the course of his or her duties, if he or she belongs to an identified group of individuals, including:
    • Members of the College of Nurses of Ontario,
    • Members of the College of Physician and Surgeons of Ontario, Medical students in training,
    • Firefighters (including volunteer),
    • Paramedics and emergency medical attendants,
    • Persons, who are employed in a correctional institution, place of open custody, or place of secure custody,
    • Police officers, civilian employees of a police service, or
    • First Nations constables and auxiliary members of a police service.

The documents required by the Mandatory Blood Testing Act are to be submitted to the Medical Officer of Health in the respondent’s local Public Health Unit no more than 30 calendar days after occurrence.  If forms are not completed and provided to the Medical Officer of Health within this time period, the Mandatory Blood Testing Act process cannot proceed.
