What is an elevated master stream device that is mounted at the tip of an aerial ladder called?

An elevated master stream device mounted at the tip of an aerial ladder is referred to as a ladder pipe. This device is essential for delivering a significant volume of water to a fire from an elevated position. Utilizing a ladder pipe allows firefighters to reach areas that may be difficult to access from the ground, providing necessary water suppression capabilities at heights that might otherwise be challenging to manage effectively.

By having the master stream at the top of an aerial ladder, it maximizes the reach and effectiveness of water application, particularly in high-rise or multi-story structures. This technique is critical in firefighting operations where quick and effective water delivery can be the difference in controlling or extinguishing a fire.

The other options listed serve different purposes in firefighting. A Neuse pipe is not a commonly recognized term in the context of aerial ladder operations, while FDC stands for Fire Department Connection, which is used for supplying water to a standpipe or sprinkler system from a fire apparatus. A ground monitor is typically used at ground level and can also deliver high volumes of water, but it does not provide the elevated capability that a ladder pipe does.
