Post-exposure Protocol for Biological Hazards

This post-exposure protocol must be followed by any employee or student who has or may have been exposed to biological hazards.


Post-exposure Protocol

Biological hazards are substances that pose a threat to the health of living organisms, primarily that of humans. This can include medical waste or samples containing a microorganism, virus, or toxin from a biological source that can affect human health. Biological hazards are identified on the Hazard Assessment and Control Form completed for each job position.

Employees and students have the potential to be exposed to biological hazards at the university. This protocol was developed to assist with immediate first aid, medical assessment, and reporting of exposure to biological hazards at the university.
