3.13. FIRE FIGHTING

The vessel is fitted with a firefighting pump that is operated from the electrical switch panel in the
wheelhouse. The power switch to activate the fire pump is in front of the coxswain. This energises
the magnet clutch on the fire pump. The port engine has to be running to operate the fire pump.

The fire sea valve (three-way valve) has to be opened to the “collect” position to enable it to be
operated. The three-way valve is left in the “open” position for the engine room bilge. The valve
handle is parallel to the pipe in which the water will flow. side of the vessel.

Fitted on the aft deck on the starboard side is the fire hose deck connection, which is painted red.
The fire hose is connected here and deployed where necessary for firefighting operations.

The fire pump can also be used as an emergency bilge pump by opening the three way valve to
the correct position in the engine room. This is on the port side of the port engine, and will then
pump out onto the aft deck at the deck fire connection point. The deck valve needs to be opened
to accomplish this.
