How often should hose teams be reassigned based on operational needs?

Hose teams should be reassigned based on operational needs as determined by the team leader. This approach allows for flexibility and responsiveness to the specific conditions and requirements of the situation at hand. The team leader has the insight and situational awareness needed to assess factors such as personnel fatigue, the evolving nature of the emergency, and the overall effectiveness of the operation. By making reassignment decisions based on real-time assessments, the team leader can ensure that all personnel remain effective and that resources are utilized efficiently.

The other options suggest set time intervals for reassignment, which may not align with the dynamic circumstances encountered during an incident. Rigid timelines could lead to inefficiencies or ineffective responses, as operational needs can change rapidly depending on the scenario.
