What is one problem with using doorways as ventilation openings?

Using doorways as ventilation openings can indeed compromise entry and exit for human use, which is critical in firefighting operations. When a doorway is utilized for ventilation, it may divert attention away from its primary purpose as an access point for firefighters and evacuation routes for occupants. If a doorway is blocked or if the ventilation process makes it less safe or accessible, it can hinder quick and effective movement in and out of the building during an emergency.

This is particularly concerning because the safe passage of personnel and the movement of people who may still be inside the structure is vital during an incident. Firefighters must always be aware of their egress routes as well as the ingress routes to ensure safety and efficiency in their operations. Effective ventilation is crucial for controlling fire behavior and smoke movement, but it must always be balanced with maintaining safe access points for those responding to the emergency.
