The fixed fire-fighting system operates automatically when the temperature in the engine room exceeds 79°C. The discharge is driven by an automatic system consisting of a glass flask filled with liquid and installed on the extinguisher cylinder. When the temperature around the flask reaches the preset level, the liquid expands until the flask breaks and the extinguisher (2) activates. The system can also be activated manually. The tie rod for manual activation (1) is located on the crew area access ladder.
By pulling the tie rod, the system stops the engines, the generators and the electric extractors automatically.
A panel located in the main helm station on the fly bridge to allow extinguisher discharge monitoring.
In case of fire in the engine room, operate as follows:
If the fire breaks out underway, perform the distress call “MAY DAY”; if the yacht is in the harbour, advise the Port Authority and evacuate all unnecessary personnel.
Do not delay fire fighting because of a rescue call.
To shut the engines down, do not only push the stop buttons but also always turn the keys.
Keep the fire fighting ie rods efficient; service them and check for their operation at regular intervals (as per rules in force).
Before setting up for navigation, it is necessary to open the lock and to have the crew access free and the fire-fighting control panel as well.
Also check that the safety pin of the cylinders has been removed.
The automatic fire-fighting system, covering exclusively a section of the engine room, under special fire conditions could not activate, for this reason IT IS ALWAYS COMPULSORY TO ACTIVATE THE SAFETY TIE ROD.
When operating the fire extinguishing system, disconnect the engine room extractors and close the air intakes. Once the fire is extinguished, ventilate the room for a long time before going inside without activating the extractors. Clean out all the powder very carefully, to prevent corrosion.
The automatic system is calibrated to detect the fire when they reach 79°C, therefore, if a beginning of a fire is found, it is absolutely necessary to actuate manually the system in order to limit damage to a minimum.
