defining the risks must include a review of how individuals inside and outside the laboratory may be exposed to the hazards. It could either be through droplets, inhalation, ingestion, or inoculation in case a biological agent has been identified as the hazard. - 1H
Define the risks
The risk assessment team must IDENTIFY the hazards and risks of the biological agents to be handled. Next, at-risk hosts, who could be humans or animals inside and outside the laboratory, must be identified. The work activities and laboratory environment including location, procedures, and equipment should also be defined. - 4W's
Define the situation
this process of evaluating the biorisk arising from a biohazard takes into account the adequacy of any existing controls and deciding whether or not the biorisk is acceptable.
Determine if risks are acceptable or not
