What should be followed during interior fire operations?

During interior fire operations, it is crucial to always have a hose line or lifeline as a guide to safety because these tools provide firefighters with a reliable means of navigating back to safety in potentially disorienting and hazardous environments. Firefighters often work under conditions of low visibility, high heat, and smoke, which can make it extremely difficult to find an exit. The hose line serves a dual purpose; it is used to deliver water for extinguishing the fire, and it also acts as a physical guide back to the exit point.

Having a hose line ensures that firefighters can remain oriented within the structure and can exit safely if conditions become untenable. This practice is a fundamental safety protocol in firefighting, emphasizing the importance of being prepared and aware of one's surroundings at all times while engaged in interior operations.
