What are the responsibilities of the 3rd Engine on a building that is 3 stories or less?

The responsibilities of the 3rd Engine on a building that is three stories or less primarily focus on RIT (Rapid Intervention Team) and sprinkler systems. RIT is a crucial function in fire operations as it provides immediate intervention for firefighters in case of an emergency or a collapse situation. This is particularly vital in smaller buildings where the risk of firefighter injury can still be substantial due to various hazards associated with fire scenarios.

Additionally, the management of sprinkler systems is also a key role for the 3rd Engine. Sprinkler systems play a significant role in fire suppression capabilities - knowing their status and operation can significantly impact the overall effectiveness of the firefighting effort on the scene.

Focusing on RIT and sprinkler management allows the 3rd Engine to support ongoing operations effectively and ensure firefighter safety, which is paramount in all fire ground situations.
