Water and fire seem like elements that cannot exist simultaneously, but the GIMS statistics are inexorable: small-size fires occur every year, taking lives and destroying expensive property. Having a serviceable fire extinguishing tool is not just a bureaucratic requirement for passing inspection, but the only chance to save yourself and passengers in a critical situation. Fire extinguisher in the boat It must be selected taking into account the specifics of operation: vibration, humidity, limited space and type of engine installed.
Many boat owners make the mistake of buying the first cylinder they find in a hardware store or leaving an old car fire extinguisher in the boat, which has long expired. device And the valves are aggressively attacked, which can cause equipment to fail at the most inappropriate moment, and it's important to understand the difference between the types of fire extinguishers and to know how to properly secure the balloon so that it doesn't become a dangerous projectile when it's braking or hitting a wave.
In this article, we will discuss the regulatory framework in detail, consider the pros and cons of powder, carbon dioxide and air-foam models, and give practical tips for maintenance and verification. Safety at sea It requires a comprehensive approach, and the right equipment is the foundation of it, and you should not skimp on this piece of equipment, because the cost of error can be too high.
GIMS regulatory requirements for fire extinguishing
The regulation of safety issues on small vessels in the Russian Federation is under the responsibility of the State Inspectorate for small craft (SIMS), according to the current regulations, every small craft equipped with an engine (whether it is a small craft or a small craft). petrol-engine For boats without an engine, fire extinguishing equipment is also strongly recommended, although not always strictly mandatory at check-in if there are no open sources of fire on board.
The basic regulation requires that the fire extinguisher meets certain parameters in terms of fire extinguishing capacity and volume. For most small vessels (boats, motorboats, PVC boats with a motor), the minimum requirement is the presence of one fire extinguisher with a volume of at least 2 liters (for liquid) or a charge weight of at least 2 kg (for powder).
⚠️ Attention: The use of fire extinguishers with expired expiration date or damaged pressure gauge (for injection models) is a violation of safety rules and may result in a fine when checking documents by the inspector of the GIMS.
It is important to note that requirements may vary depending on the class of vessel and type of engine. stationary In a closed compartment, regulations may require an automatic fire extinguishing system or an additional set of handheld equipment. Always check the current version of the small craft Rules before you get on the water.
Types of fire extinguishers: what to choose for a boat
The market offers several main types of fire extinguishers, and choosing the right option for a boat requires a balanced approach. Each type has its advantages and disadvantages in water conditions. The main candidates are powder (OP), carbon dioxide (OC) and air foam (ORP) devices.
Powder fire extinguishers (OP) They are most common because of their low cost and versatility. They effectively extinguish solids, liquids and electrical equipment. However, pressure-emitted powder creates a cloud of fine dust that greatly reduces visibility in the enclosed space of the cabin and can cause choking or allergic reactions. In addition, the powder is difficult to wash off surfaces and has corrosive activity.
- 🔥 Advantages of OP: low price, wide temperature range of operation, the possibility of extinguishing electrical equipment up to 1000V.
- 💨 Disadvantages of OP: pollution of the cabin, reduced visibility, the possibility of sticking together the powder during vibration (clumping).
Carbon-acid fire extinguishers (OC) They're considered more suitable for boats in terms of clean extinguishing. They leave no traces, they don't spoil property and they effectively displace oxygen by stopping burning. The main advantage is that they can extinguish electrical installations under high voltage without the risk of short circuit. But they have a significant disadvantage: when the gas exits, it is very cooled, and the socket can reach temperatures of -60 ° C, which is dangerous when touched.
Features of storage of OU in the sun
Carbon dioxide extinguishers are sensitive to overheating. As the temperature rises inside the cylinder, pressure increases. If you leave such an extinguisher in the open sun in a black case on the deck, there is a risk of valve activation or depressurization. It is recommended to store them in shaded runduks.
Air foam fire extinguishers (AFP) They're effective in quenching solids and combustible liquids (gasoline, oils), and they cover the surface, blocking oxygen, but they have a critical limitation: they can't be used to extinguish electrical equipment under voltage because the foam conducts current, and they're afraid of negative temperatures, which makes them unheated in cold weather.
specifications comparison table
To make the choice easier, we present a comparative table of the main parameters of the different types of fire extinguishers relevant for small vessels.
| Parameter | Powder (OP) | Carbon dioxide (OC) | Air foam (AFP) |
|---|---|---|---|
| Class A extinguishing (solid) | Yes. | No (weakly) | Yes. |
| Class B extinguishing (liquids) | Yes. | Yes. | Yes. |
| Class C extinguishing (gases) | Yes. | Yes. | No. |
| Extinguishing of electrical equipment | Up to 1,000V | Up to 10,000. | Forbidden. |
| Temperature range | -40...+50°C | -40...+50°C | +5...+50°C |
The table shows that carbon-extinguishers They're better at quenching and safety for electronics, but the powders are more versatile in temperature and price. ORP models have a very narrow niche for water use because of the fear of frost and current foam.
Rules for accommodation and anchorage on board
It's not enough to buy a quality fire extinguisher, it needs to be properly placed. The main problem with boats is constant vibration and pitching. If the balloon is just standing in the corner or lying on the floor, when hit by a wave, it can fall, damage or, worse, become a traumatic object. The fastening must be rigid, reliable and provide quick access.
The best place to place is near the exit of the cockpit or in the john at the entrance, but not in the immediate vicinity of the engine, where a fire source can occur, blocking access to the extinguishing means. It is best to use special metal brackets or clamps that are screwed to the board or bulkhead. Plastic holders, complete with car fire extinguishers, often do not withstand sea moisture and vibration, so they are better replaced with a new one. metal-stap with a rubber pad.
☑️ Verification of fire extinguisher attachment
It is important to protect against direct sunlight and precipitation. Although modern fire extinguishers have protective coatings, constant exposure to ultraviolet and salt water accelerates the corrosion of the case and the destruction of rubber seals. The ideal option is storage in a waterproof but easily openable box or a special case made of dense fabric.
⚠️ Attention: Never place a fire extinguisher in the vicinity of a fuel tank or carburetor. In the event of a fire in the engine compartment, you simply will not be able to approach the extinguishing device.
Service and time frame for verification
Operation of a fire extinguisher on a boat requires more careful control than in a car or garage. Humidity and salt mist are the main enemies of metal and machinery. Regular visual inspection should be carried out before each outing. First of all, pay attention to the integrity of the seal, the condition of the checks and the pressure gauge (if the model is pumped).
If it has moved into the red zone (left or right), the fire extinguisher needs to be recharged or replaced. Even if the pressure is normal, once a year it is recommended to remove the fire extinguisher, wipe the body with dry rags, lubricate the moving parts of the mechanism (without getting into the holes) and check the date of the next check, stamped on the case or label.
- 📅 Quarterly: External examination for corrosion and dents.
- 🔧 Every year: Checking the charge mass (weighing) and the state of the powder (for OP).
- 🔄 Every 5-10 years: complete recharging and hydraulic test of the cylinder (depending on the type).
Pay special attention to powder fire extinguishers. The powder has the ability to track and form solid lumps, especially when constantly shaking. It is recommended to remove the fire extinguisher from the mount several times a season, flip it upside down and slightly tap to loosen the contents, this will ensure a confident jet release in an emergency.
To protect the checks and the locking mechanism from corrosion, you can use a special silicone spray lubricant, apply it in a thin layer on the moving parts, avoiding getting inside the socket.
Actions in the event of a fire on a boat
The fire extinguisher is useless if you don't know how to use it properly or panic. The algorithm for detecting a fire on a boat should be worked out to automatism. The first thing you need to do is turn off the engine and shut off the fuel supply if it is possible to do it safely. Then you should get the boat to clean water, away from coastal vegetation and other boats.
When you approach the fire from the windward side (so that the flames and smoke do not carry you), rip the seal, pull the check, and point the socket or nozzle at the base of the flame. Press the lever, start extinguishing. The powder jet should "pull" the flame from the edge to the center, and the carbon dioxide jet should direct the jet of gas directly to the burning surface. Do not try to extinguish the spilled gasoline with a direct jet under pressure, so as not to splash the fuel and increase the area of the fire.
⚠️ Attention: If the fire has covered more than 30% of the boat's area or the fuel tank has caught fire, do not attempt to extinguish it yourself.
After using the fire extinguisher, it must be sent for recharging, even if a small amount of the substance was released, the pressure in the cylinder has dropped, and the leakage is broken, making the device unsuitable for further storage.
The rule is, first shut off the fuel and turn off the engine, then start putting out the fuel, and without eliminating the fuel source, the fire can flare up again.
Can I carry a fire extinguisher in a boat in winter?
Yes, but with limitations. Powder and carbon dioxide fire extinguishers are designed to work at low temperatures (up to -40 ° C. However, before using the frozen cylinder, it is recommended to warm up in heat, since the pressure inside has fallen, and the effectiveness of extinguishing will decrease. Air-foam extinguishers cannot be stored in winter - the liquid will freeze and burst the case.
How often should I change the fire extinguisher on the boat?
The life of the fire extinguisher depends on its type and the material of the shell. Steel cylinders are subject to re-examination every 5 years, and full replacement occurs after 10-15 years. However, if the shell is damaged by corrosion, dents or the powder / gas has expired, replacement is required immediately.
Will a fire extinguisher be suitable for a boat?
Formally suitable if it meets the requirements for volume (minimum 2 liters / kg) and has a valid marking. However, car fire extinguishers often have plastic holders and less durable coating, so for a boat they need to be additionally protected from moisture and securely fastened.
