The occurrence of an open fire in a household appliance is always a stressful situation that requires an instant and, most importantly, correct reaction. When it lights up refrigerator, you need to act decisively, but without panic, since not only the safety of property, but also the lives of people depend on the first seconds. The basic rule is: while the device is connected to the mains, using water for extinguishing is strictly prohibited due to the risk of electric shock.
Modern models, whether Liebherr, Bosch or Indesitcontain many flammable materials, including a plastic case, insulation and refrigerants that can support combustion. The primary task is to localize the source of the fire and cut off the power supply. It is important to understand that even after turning off the switch in the panel, a residual charge may remain in the capacitors, so safety must come first.
In this article we will look at which fire extinguishing agents are most effective for household electrical appliances, how to evacuate correctly and what to do if a flame has engulfed the inside of the chamber. Knowing these nuances will help you not get confused at a critical moment.
Priority actions in case of fire
The first thing to do when detecting smoke or fire is immediately de-energize the room. Do not attempt to pull the plug from the outlet with bare hands if an open flame or heavy smoke is already visible, as the insulation of the wire may have melted. The best solution would be to turn off the electricity through the circuit breaker in the apartment panel or the switch on the staircase.
⚠️ Attention: If the fire is in a hard-to-reach place or the smoke has become too caustic, do not try to put out the fire yourself. Immediately leave the premises, close the door behind you and call the fire department at 101 or 112.
After the power is turned off, you can begin to assess the situation. If the fire has just started and the source is visible, you can try to eliminate it using available means. However, if the flame spreads to curtains, furniture, or covers more than 1 square meter of area, further fire fighting becomes life-threatening. In this case, the only correct decision would be to evacuate all residents and meet with fire brigades.
Therefore, even with a small fire, it is necessary to ensure an influx of fresh air by opening the windows, but without creating a draft that could fan the flames. Safety people always takes priority over saving household appliances.
Choosing a fire extinguisher for electrical appliances
When asked how to extinguish a burning refrigerator, there is a clear answer from experts: powder and carbon dioxide fire extinguishers are best suited. These products belong to the class E (for extinguishing electrical installations under voltage, although it is better to remove the voltage) and effectively cope with the combustion of solids and liquids without conducting electric current.
- 🔥 Powder fire extinguishers (OP) - universal, create a dense film that blocks access oxygen, but heavily pollute the room with fine dust.
- ❄️ Carbon dioxide fire extinguishers (CO) - do not leave traces, cool the source of fire, but require caution when used in small rooms due to the release of CO2.
- 💧 Water fire extinguishers with additives (OA) - can be used ONLY after complete disconnecting the device from the network and removing residual voltage.
The use of foam or air-foam fire extinguishers is allowed only on completely de-energized equipment. Water and foam are conductors of electricity, and their use on an energized device is guaranteed to lead to a short circuit and electrical injury to the extinguisher. Therefore, if you are not 100% sure of a power outage, choose powder or carbon dioxide.
When buying a fire extinguisher for your home, pay attention to its capacity. For the kitchen and hallway, the best choice would be a device with a volume of 2-4 liters or 2-5 kilograms. Heavier models will be difficult to use quickly in conditions of smoke and limited space in the kitchen.
Strictly prohibited extinguishing methods
There are a number of actions that can lead to catastrophic consequences in the event of a fire in the refrigerator. The most common and dangerous mistake is trying to douse the flame with tap water while the cord is plugged into the outlet. Water containing salts and impurities is an excellent conductor, and the current will instantly pass through the stream to a person.
⚠️ Attention: Never use water to extinguish live electrical appliances. This is a direct threat to life.
It is also dangerous to cover a burning refrigerator with a thick cloth if the fire has already spread inside the body. The fabric can catch fire on its own, but the access of oxygen through ventilation holes and leaks will still allow the fire to flare up with renewed vigor. In addition, when approaching with a cloth, you risk getting burns from ignited vapors or rupture of the compressor.
Another mistake is trying to disassemble the refrigerator while it is burning. Plastics, insulation and refrigerants emit acrid fumes when heated. Inhalation of combustion products of freon and plastic components can cause pulmonary edema and loss of consciousness in a matter of minutes. Smoke toxicity often more dangerous than the fire itself.
Why should you not fight off the flame with your feet or heavy objects?
Mechanical impact on a heated body may lead to depressurization of the cooling system. A sudden release of refrigerant under pressure can knock you down or cause explosive combustion if the concentration of vapors in the air reaches a critical level.
Combustion features of modern refrigerators
The design of modern refrigerators, such as Samsung or LG, involves the use of various materials that lead to behave differently during a fire. The thermal insulation layer located between the inner and outer casing is often made of polyurethane foam. This material burns very intensely, melts and emits a huge amount of black, choking smoke.
The compressor, which is the heart of the system, contains oil, which is also a flammable substance. If overheated or short-circuited, the oil may ignite and leak out, creating a spreading fire. In older models, freon circulated in the system, which did not burn, but modern environmentally friendly refrigerants (for example, isobutane R600a) are explosive gases.
| Component | Material | Hazard during combustion | Extinguishing method |
|---|---|---|---|
| Housing | Plastic, steel | Melting, toxic smoke | Powder, CO2 |
| Insulation | Polyurethane foam | Rapid spread of fire | Powder, water (after shutdown) |
| Compressor | Metal, oil | Oil burning, explosion | Powder, sand |
| Refrigerant | Gas (R600a) | Explosion | Cooling, insulation |
It is the presence of flammable gas R600a in modern models that makes a fire in a refrigerator potentially explosive. If you hear a hissing or whistling sound from the back of the unit, this may indicate a leak in the system. In such a situation, you must immediately move to a safe distance.
Step-by-step instructions for extinguishing a fire
If you decide to extinguish the fire yourself and are convinced of the safety of this action, follow a clear algorithm. Chaotic actions will only worsen the situation. First, provide yourself with an escape route - the door to the kitchen should not be blocked by furniture or fire.
☑️ Algorithm of actions in case of fire
Direct Fire extinguisher nozzle at the base of the flame rather than at the top of the fire. Release the contents with short presses, gradually approaching the hearth. If a powder extinguisher is used, be careful not to create a cloud of dust that will reduce visibility and make breathing difficult. After eliminating the visible fire, do not turn your back to the device - smoldering areas may flare up again.
If there is no fire extinguisher at hand and the electricity is turned off, you can use a thick woolen blanket or felt. Throw it so as to completely block the access of air to the fire. However, if the insulation inside the refrigerator cabinet is already on fire, this method may not work due to the presence of oxygen inside the chamber.
Actions after extinguishing the fire
After the fire is defeated, the room must be thoroughly ventilated. The combustion products of plastic and insulation settle on surfaces and remain in the air, posing a health hazard. Do not turn on electrical appliances and lighting until you are sure that there is no smoke or burning smell in the wiring.
A burnt refrigerator, as a rule, cannot be restored. Even if the exterior of the housing is intact, the heat could damage the electrical wiring inside the walls, melt the insulation of the cables and deform the camera. An attempt to turn on such a device may lead to a repeated short circuit.
Be sure to call representatives of the fire service to draw up a report, even if you dealt with the fire on your own. This document is necessary for the insurance company if your property is insured against fire. In addition, specialists can identify hidden sources of smoldering in walls or ventilation ducts.
⚠️ Attention: Do not try to repair a burnt-out refrigerator yourself or sell it for parts without a full diagnosis. Residual gases and damaged electronics can be dangerous.
Prevention of fire hazards
In order not to wonder how to put out a burning refrigerator, it is better to exclude the causes of the fire in advance. Regularly check the condition of the outlet into which the device is plugged in. It should not heat up, spark, or smell like burning plastic. For powerful compressors, it is better to use separate sockets with grounding.
Keep the condenser on the back wall of the refrigerator clean. A layer of dust and pet hair can act as an excellent heat insulator, causing the compressor to overheat and ignite the dust. Cleaning should be carried out at least once a year, having first disconnected the device from the network.
Do not overload the electrical network by including a refrigerator, microwave and electric kettle in one extension cord. Voltage surges can also cause electronic failure and fire. Installing a voltage stabilizer or voltage control relay will help protect equipment and prevent fire.
Is it possible to store a refrigerator on a balcony?
Storing a working refrigerator on an unglazed balcony or in an unheated garage is dangerous. Condensation inside the wiring and temperature changes can cause a short circuit. In addition, direct sunlight heats up a dark compressor, increasing the risk of overheating.
Is it possible to extinguish a refrigerator with water if it is unplugged?
Technically, if the appliance is completely de-energized and unplugged, the water does not conduct current. However, residual charge may remain inside the components (capacitors). In addition, contact with water on hot parts can cause thermal shock and destruction of the metal, as well as the formation of steam, which will displace oxygen but also burn the skin. It is better to use specialized means.
What to do if the refrigerator catches fire and there is no fire extinguisher?
If there is no fire extinguisher and it is impossible to turn off the electricity, leave the room and close the door to limit the flow of oxygen. If the power is turned off, you can try to cover the fireplace with sand, soil from flower pots, or cover it with thick non-synthetic fabric. Do not risk your life to save equipment.
Do modern refrigerators explode in a fire?
Modern refrigerants, such as isobutane, are flammable and, in a certain concentration with air, are explosive. In the event of a fire, the integrity of the tubes is damaged, gas escapes and can flare up with a characteristic pop or explosion. Therefore, if there is strong smoke and hissing from the refrigerator, it is better not to approach it.
