Biological Hazards

Health-care workers are potentially at risk from exposure to biological hazards in the workplace.

These exposures can include medical waste, microorganisms, viruses or toxins from biological sources that can affect health. Over the past decade, a number of outbreaks related to infectious diseases (such as norovirus, Clostridium difficile and influenza) have affected workers and others in health and community care workplaces.

Employers have a responsibility to control these biological hazards in the workplace.

When inspectors find violations, they can lay charges and prosecute offenders or issue orders. Consult with your ONA bargaining unit leadership and Labour Relations Officer for help, but if danger is imminent, call your local Ministry of Labour office.
