When entering a structure on fire, at which side of the flow path should firefighters aim to enter for safety?

Firefighters should aim to enter on the intake side of the flow path for safety. The intake side refers to the area where fresh air is being drawn into the fire. Entering on this side allows firefighters to position themselves away from the most dangerous side of the fire, where the heat and flames are intense. This approach is critical for ensuring their safety as they navigate through the structure while suppressing the fire.

When firefighters enter on the intake side, they have a better chance of finding a clearer path, limiting their exposure to heavy smoke and heat that would typically be present on the exhaust side, where smoke and gases are leaving the structure. This strategic entry point also enhances the effectiveness of their operations by allowing them to control and attack the fire from a more advantageous location, improving their overall situational awareness and reducing the risk of entrapment.
