The situation when the refrigerator caught fireis classified as extremely dangerous and requires an instant response. Any delay in making decisions may result in the fire spreading to kitchen furniture, curtains and other combustible materials. The first and most critical action is always de-energizing the appliance, since the burning of live electrical wiring makes it impossible to use most fire extinguishers and water.
Plastic, polyurethane foam and wire insulation used in the design refrigeration chamber, when burned they emit toxic substances. The smoke from burning equipment is extremely toxic, so the task is not only to save property, but also to ensure one’s own safety. If you notice a burning smell or see smoke coming from behind the back wall or base, you need to act without delay.
Panic in such situations is the main enemy. A clear understanding of the sequence of steps allows you to minimize damage. In this article we will analyze a detailed algorithm of actions, consider what to extinguish modern household appliances and what mistakes can cost lives.
Primary actions when a fire is detected
Once you understand that the refrigerator caught fire, your first thought should be to cut off the electricity supply. Do not attempt to search for the cause of sparking or disassemble the rear panel while the unit is plugged in. Go to electrical panel (located in the apartment or on the landing) and turn the corresponding switch to the "off" position.
If access to the panel is difficult or you do not have time to get to it, Unplug the power cord from the outlet. This must be done carefully, preferably using dry cloth or clothing, so as not to get burned or receive an electric shock if the insulation is already damaged. After turning off the power, the fire may not go out on its own, since many materials continue to smolder.
⚠️ Attention: If the flames have already engulfed a significant part of the kitchen or you feel heavy smoke, do not risk your life. Immediately leave the room, tightly close the door behind you, and call the fire department at 101 or 112.
After a power outage, assess the scale of the disaster. If the fire has just started and is localized in the area of the compressor or wiring, you can try to put it out yourself. However, if the flame spreads to curtains or a kitchen set, fighting on your own becomes deadly.
How to extinguish a refrigerator: choosing a fire extinguisher
The choice of fire extinguishing agent depends on whether you succeeded turn off the electricity. If the device is still energized (even if you simply pulled out the plug, but did not de-energize the panel, and there is still current in the wiring), the use of water is strictly prohibited. Water is a conductor and can cause a short circuit or electric shock.
Fire extinguishers are ideal for extinguishing electrical appliances. Carbon dioxide is good because it leaves no traces and does not spoil equipment, but it quickly erodes and is less effective at putting out flames over a large area. Powder compositions (marking carbon dioxide (CO2) or powder fire extinguishers. Carbon dioxide is good because it leaves no traces and does not spoil equipment, but it quickly erodes and is less effective at putting out flames over a large area. Powder formulations (labeling ABC or BC) are more effective at knocking down fire, but create a dense curtain of dust, which is then difficult to remove.
If at hand There is no fire extinguisher, and the fire is weak, you can use a thick cloth (wool blanket, felt felt) soaked in water, but only after a complete power outage! The source of the fire is covered with a cloth, blocking the access of oxygen.
☑️ Preparedness for a fire in the kitchen
Why the refrigerator catches fire: the main reasons
Understanding the reasons helps prevent the situation from reoccurring. Most often fire occurs due to overheating of the compressor. If the motor runs non-stop due to a freon leak or thermostat malfunction, it can heat up to temperatures that ignite dust and oil.
The second common cause is short circuit in the wiring. Old refrigerators or appliances with damaged wire insulation on the back panel may spark. It is especially dangerous if flammable dust has accumulated near the sparking site or there is a paper towel.
The third reason is a malfunction of the starting relay. This small element is responsible for starting the engine. When it breaks down, the compressor hums, but does not start, consuming huge current and heating up to critical values.
Risk of the defrost
In models with the No Frost system, the defrost heating element often fails. If the timer is “stuck” in defrost mode, the heating element works constantly, overheating the plastic evaporator, which can lead to a fire inside the chamber.
Danger of refrigerants in case of fire
Modern refrigerators are filled with various types of refrigerants. Old models may contain freonwhich itself does not burn, but upon contact with an open flame it decomposes to form phosgene a chemical warfare agent. Inhaling freon combustion products is deadly.
New environmentally friendly models often use hydrocarbon refrigerants, such as isobutane (R600a). This substance is explosive and flammable. If there is a leak in the system and gas has accumulated in the compressor niche, any spark can cause a micro-explosion that scatters burning parts throughout the kitchen.
| Refrigerant type | Flammability | Fire hazard | Marking |
|---|---|---|---|
| Freon (R12, R134a) | Does not burn | Phosgene release (poison) | CFC, HCFC |
| Isobutane | High | Explosion, open fire | R600a |
| Propane | High | Explosion, intense combustion | R290 |
| Ammonia | Weak | Toxic fumes | R717 |
It is precisely because of the risk of explosion and toxic smoke in the event of a fire in the refrigerator that you should not be in the room without respiratory protection. When the refrigerator burns, with isobutane, seconds count until a possible pop occurs.
What you absolutely cannot do
When extinguishing household appliances, people often make fatal mistakes, guided by instincts that work in other situations, but not here. The main mistake is trying fill the burning device with water from a tap or bucket without making sure the electricity is turned off. This is a guaranteed path to electrical injury.
You should also not try to put out the flame with a rag if it is synthetic. Synthetics melt and stick to the skin, worsening burns, and can also catch fire. Use only natural fabrics (cotton, wool) and only when the power is turned off.
⚠️ Attention: Do not open the refrigerator door if there is a fire inside or near it. A sudden influx of oxygen will cause a flash of flame (draft effect), and the fire will hit you in the face.
Another dangerous mistake is inhaling the breath “just in case” to check what is burning. The toxicity of smoke from burning plastic and electronics is so high that loss of consciousness can occur within a few breaths.
Consequences and recovery after a fire
If you managed to put out the fire at an early stage, the refrigerator is most likely beyond repair. Even if the body is intact, wire insulation could melt, and the electronics could fail due to a power surge or overheating. Operation of such a device is dangerous.
After using a powder fire extinguisher, fine dust penetrates into all cracks. It conducts current and causes corrosion of metals. It is almost impossible to completely clean the equipment from powder without complete disassembly and professional dry cleaning, which is often not economically feasible.
If the kitchen is damaged, it is necessary to thoroughly ventilate the room. Residual products from burning plastic settle on surfaces and can cause allergies or poisoning for a long time. It is better to replace furniture with damaged plastic or chipboard, as the burning smell eats deep.
Prevention of household appliance fires
To prevent a situation where the refrigerator caught firecarry out regular preventive maintenance. Check the condition of the power cord: there should be no bends, cracks or signs of heating. The socket into which the device is plugged in should not spark or heat up.
Pay special attention to the back wall. There is a condenser (grid) located there, which should be freely washed by air. If you move the refrigerator close to the wall or force it with things, the compressor will overheat. Also regularly remove dust from the compressor and wires with a vacuum cleaner.
Monitor the operation of the device. If the refrigerator starts working continuously, making unusual sounds (clicking, humming) or getting very hot on the sides, this is a signal of a malfunction. In this case, call a technician for diagnostics without waiting for a critical breakdown.
Frequently asked questions (FAQ)
Is it possible to use a refrigerator after it smokes but does not catch fire?
No, operating such a device is dangerous. Smoke indicates overheating of the insulation or melting of parts. Even if there was no visible fire, irreversible changes in the wiring could have occurred inside, which would lead to a fire the next time you turn it on.
Which fire extinguisher is best to keep in the kitchen?
The optimal choice for the kitchen is a fire extinguisher OP-4 (powder) or OU-3 (carbon dioxide). Powder is universal and cheap, but it pollutes the room a lot. Carbon dioxide is cleaner, but requires caution when used in small spaces due to the displacement of oxygen.
What to do if the wire in the wall behind the refrigerator catches fire?
Immediately turn off the power to the apartment through the input machine. Do not extinguish with water. If the fire is inside the wall, call the fire department. You can open the wall yourself only after the combustion has completely stopped and if you have the skills, but it is better to entrust this to professionals.
Do modern refrigerators explode?
On their own - extremely rarely. However, models operating on gas R600a (isobutane)if there is a leak and concentration of gas in a confined space, the compressor niches may slam in the presence of a spark. Therefore, it is important to monitor the integrity of the system.
Wiring service life
The average safe operation life of refrigerator electrical wiring is 10-12 years. After this period, the insulation becomes brittle (brittle) and can crumble, causing a short circuit.
