Why is it important to monitor the water level in the onboard tank?

Monitoring the water level in the onboard tank is crucial because it allows the operator to determine if additional water is needed before the tank is emptied. Keeping track of the water level helps in maintaining a continuous and effective water supply during firefighting operations. If an operator is unaware of how much water remains in the tank, they risk depleting their water supply and potentially compromising their ability to extinguish a fire or effectively respond to an emergency situation.

By knowing the water level, the operator can plan refills in a timely manner and ensure that they are always prepared for the demands of the operation. This process is essential for efficient water management and operational safety during emergencies.
