What is the main piece of equipment the #3 person on the first arriving engine company brings for high rise operations?

In high-rise operations, the primary focus is on efficiently accessing the upper floors and managing the unique challenges presented by tall buildings. The high fire bundle is specifically designed for these scenarios, as it typically includes a hose line, nozzle, and other necessary equipment to quickly establish a water supply on upper floors. This system is optimized for vertical transport and can often be carried by a single firefighter, allowing for quicker deployment in a high-pressure environment.

The high fire bundle is essential because it enables immediate firefighting capability and helps maintain effective communication and coordination among crew members. This piece of equipment is lightweight and manageable, making it ideal for navigating stairwells and other confined spaces commonly found in high-rise structures.

Other equipment listed, like fire hoses alone, while crucial, do not provide the same level of readiness for high-rise situations specifically. Rescue tools and aerial ladders serve different purposes and may not be the immediate priority for the #3 position when the first engine arrives, as establishing a line for immediate fire suppression takes precedence.
