In Episode 13, check out UL's Fire Safety Research Institute (FSRI) research engineer, Keith Stakes, as he discusses the impact of opening the front door as it relates to ventilating the structure:

Forcing the front door needs to be considered in the same way as any other form of horizontal ventilation. When a door is opened for firefighter entry, it is also opened for airflow and can create a new flow path for the fire. Coordination of forcing the door and suppression is key.

To learn more about this consideration, take FSRI’s Impact of Horizontal Ventilation on Fire Behavior online training course.
