2.6.1 Automatic fire-fighting system

Each fire-fighting system consists of an automatic fire extinguisher located inside the room.

The fire fighting system installed on board has been designed to complete the discharge in a few seconds from the activation. In this way it is possible to reduce the time in which the fire can develop and expand, thus causing damages.

After discharge, the extinguishing agent reaches every part of the protected area (engine room and/or technical room), does not damage sensitive equipment and leaves no residue.

It allows avoiding also the costs inherent to cleaning and operation restoration, therefore it allows resuming immediately the activities on-board.

The discharge is automatically activated by means of a sprinkler, installed on the bottle and filled with liquid that, when the room’s temperature increases, expands and breaks the sprinkler itself, causing system activation.

The automatic fire extinguishing system is managed by an electronic control unit (SHUT DOWN). In case of fire in the engine room or the technical room, the time when the discharge the extinguisher is activated, the control unit stops the propulsion engine, the generator and the engine room extractors and the technical room extractor; take anyway on the bridge and put the keys of the engines ignition in OFF.

The automatic fire-fighting system may not activate in particular fire conditions; it is therefore necessary to act on the safety rods to activate the fire-fighting systems manually.

DANGER

The automatic fire fighting system that protects the engine compartment and the system room may not start under particular fire conditions and, therefore, it is ALWAYS COMPULSORY TO MANUALLY OPERATE THE FIRE FIGHTING CONTROL TIE RODS.

CAUTION

If a fire is detected, it is necessary to manually operate the system, without waiting for the automatic activation, in order to minimise the damage.

The tie rods for fire fighting system manual activation of engine room and technical room are located on the starboard side, opposite to the helm position.
Operating the handle of the tie rod of the room involved in the fire, by means of a sheathed steel cable, it is possible to activate the relevant bottle’s discharge, if the discharge has not yet been activated automatically, and simultaneously the SHUT DOWN system stops the fuel supply (engine room) and stops the air extractors (engine room and technical room).

The fire fighting control tie rod carries out the following functions:

DANGER

Each fire extinguishing tie rod is provided with a safety pin, that must always be inserted in order to avoid accidental discharges of the gas fire extinguisher.
The safety pin, when inserted, prevents discharge activation by means of the tie rod. The safety pin must be removed only when you intend to operate the extinguisher discharge tie rod.

On the main deck, the starboard side, opposite to the console is the panel that indicates the state of charge of the engine room fire extinguishers.

In case of fire in the engine room, carry out the following operations as soon as possible:

In case of fire in the utility room, carry out the following operations as soon as possible:

In addition, there is the control panel, equipped with optical and acoustic alarm, manages and monitors the sprinkler system of the engine room:

DANGER

In case of fire, use the “OVERRIDE” to restart the engines, only in case of collision risk or during navigation in narrow waters.
