For the safety of fire fighters, __________ is/are attached to the pump.

In firefighting operations, the safety of firefighters is paramount, and one crucial component that enhances this safety is the relief valve or pressure governor attached to the pump. This device plays a vital role in ensuring that the water pressure generated by the pump does not exceed safe levels, thereby preventing equipment damage and ensuring operability under high-pressure scenarios.

When a fire pump generates excessive pressure, it can lead to dangerous situations, such as hose rupture or injury to firefighters from the sudden release of water. The relief valve or pressure governor automatically regulates and maintains the appropriate pressure, allowing firefighters to focus on their tasks without the added concern of equipment failure or personal injury due to pressure-related incidents.

Other options like a water hose, auxiliary tank, or fire suppression system may support firefighting efforts in different capacities but do not specifically contribute to the pressure management and safety of the pump system itself. Therefore, the relief valve or pressure governor is essential for maintaining a safe operational environment in high-pressure firefighting situations.
