Fire extinguishers used on board pleasure craft must be of an approved type. It is not required periodic visit. The fire extinguisher must still be kept in good repair and, if the indicator is present, must be in the charging position (green area).
- Class A: organic solids that form brace (paper, wood, coal, rubber).
- Class B: flammable liquids and solids liquescent (alcohols, gasoline, lubricants, paints, waxes).
- Class C: flammable gases and vapors, liquefied gases (hydrogen, methane, acetylene, LPG).
- Class D: combustible metals and molten metals (zinc, sodium, potassium, magnesium, lithium).
- Class E: fire of electrical appliances in the voltage.
- Fixed: I am fixed installations equipped with sensors that are activated in case of fire automatically. They are normally CO2. On some devices you can find shower systems that use water
- Moving: From consist extinguishers What are placed on board In the various local and What WE CAN shift manually.
Fire extinguishers are cylinders equipped with a nozzle for emitting the extinguishing product. The jet is operated by a lever or a button with a safety to prevent accidental actuation. Some powder extinguishers also have a pressure gauge that indicates the charging status.
The homologated fire extinguishers, normally used in boating will be loaded with the following products:
- Foam: extinguishers are uncomfortable for small boats because they have to be large to be effective. Do not use on electrical systems: in fact, being water-based increase the conduction of electricity. They are used for classes A and B (liquid and solid fuels)
- CO2: They are carbon dioxide extinguishers that act by means of sudden cooling of the temperature. CO2 is toxic and does not leave you breathe the fumes. And ‘the best fire extinguisher for electrical systems and flammable gases
- Dust: on board the pleasure craft are almost always extinguishers of this type. Dust smothers the fire, forming a thick blanket over the burnt parts, assisted by the small charge of CO2 that is used to eject the powder itself which acts for cooling. The powder extinguisher must be checked at least every 12 months: dust may amalgamate on the bottom and need arises not be expelled. It ‘a good idea to shake the extinguisher from time to time to keep the powder in efficiency.

In the above tables, the number preceding the letter B indicates the extinguishing capability of the extinguisher in accordance with international unifications. The higher the number, the greater the extinguishing capacity; the battery capacity indicated in the tables is the minimum requirement. The letter B indicates the designation of the class of fire that the extinguisher is suitable to extinguish. On recreational units they can also be arranged extinguishers approved for classes of fire A or C provided also approved for fire class B.
- Fuel leaks and damage to the fuel system
- Still burning cigarette butts
- Sparks caused by short circuit
- Leakage of cooking gas
- Turning on the stove with the air full of gas or fuel vapors
- Explosion of gas cylinders or fuel tanks
It is therefore necessary to always observe the following precautions:
- During supplies: do not smoke, extinguish all the fires, keep the engines off, avoid spilling fuel
- Stow carefully the fuel tanks and the gas cylinders in a place sheltered from the sun and ventilated
- Maintain a controlled and efficient electrical system
- Keep covered the poles of the batteries and disconnect the cables during stops
- Dell’elettroestrattore control the operation of which is equipped with the internal combustion engine (the elettroestrattore is an exhaust fan, located in the engine compartment, which comes into operation automatically inserting the ignition key)
- It would be useful to have, on a wall of the engine compartment, an access hole through which to insert the extinguisher nozzle to extinguish a possible fire without opening the access hatch.
- If the fire is put outside the fire downwind maneuvering adequately with the boat and then turn the engine off and block the flow of fuel. The flames will propagate well outboard and fuel does not feed well.
- Remove oxygen: without it, the flames will go out by themselves. A fire blanket is certainly a good way.
- Do not use water in the presence of gasoline and liquid inflamed: they float on water and burn even better helped by the air that contains oxygen.
- Use the extinguisher from upwind flames and direct the jet at the base of the flames in the meantime avoiding to breathe.
- If there is not life threatening launch the PAM PAM PAM.
- In case of life-threatening launch MAY DAY.
- To return to port make a “special incidents Complaint”.
- If the fire has developed into a port on a half burned away from the other boats, and in the extreme case, sink it.
