A situation when smoke starts coming out of a household appliance or an open flame appears causes panic even in cold-blooded people. A refrigerator that operates 24 hours a day and contains flammable refrigerants in a closed circuit can become the source of a serious fire if it malfunctions. You need to react instantly, since seconds count, and the spread of fire in the confined space of the kitchen occurs rapidly.
The primary task is not to save the food or the unit itself, but to ensure the safety of the lives of household members and prevent the fire of the entire living space. Electric current and specific internal insulation materials create unique risks that require a specific approach to extinguishing. Ignoring electrical safety rules at such a time can lead to serious injury or death.
Initial actions when smoke is detected
The very first and critical step is to completely deenergization the premises. If you see smoke or sparks coming from the refrigerator, under no circumstances try to first understand the cause or look for the cause of the malfunction. It is necessary to immediately de-energize the apartment or house by turning off the input circuit breaker on the electrical panel. This action breaks the circuit and prevents a short circuit that can spread to the wiring of the walls.
If access to the panel is difficult or impossible, it is permissible to unplug the power cord from the socket, but only under the condition that the plug and socket itself are not engulfed in flames or melted. Touching exposed wires or wet surfaces of the device is strictly prohibited. After a power outage, you should immediately evacuate all people and animals from the premises, since the combustion products of plastic and insulation are toxic.
⚠️ Attention: Never use water to extinguish an electrical appliance that is plugged in! Water is a conductor of electricity, and its contact with energized elements will result in instant electric shock to the person holding the container.
After ensuring your own safety and turning off the electricity, you must call the fire service by calling 101 or 112. The dispatcher must clearly inform the address, floor, presence of people in the building and that the electrical appliance is on fire. While rescuers are on the way, you can try to localize the fire, but only if it does not threaten your life and you have suitable means.
The correct choice of fire extinguishing agents
The effectiveness of fighting household appliance fires directly depends on the type of fire extinguisher used. For refrigerators, which are electrical installations under voltage (until a guaranteed shutdown), not all compositions are suitable. Using the wrong substance can make the situation worse by causing a splash of burning liquid or a chemical reaction.
The best choice for extinguishing electrical appliances is carbon dioxide (CO2) fire extinguishers. They do not conduct electricity, leave no traces and effectively displace oxygen from the combustion zone. The use of powder fire extinguishers is also permissible, however, they create heavy dust, reduce visibility and can damage the electronics of other devices in the room with fine dust.
It is strictly forbidden to use foam and water fire extinguishers if there is even the slightest risk of maintaining voltage in the network. The foam contains water and can become a conductor of current to the operator. Also, you should not rely on household aerosols that are not intended for extinguishing electrical installations, as they may not cope with the combustion temperature of polymers.
- 🔥 Carbon dioxide fire extinguisher - ideal for electrical appliances, cools and insulates from oxygen.
- 💨 Powder fire extinguisher - effective, but highly polluting the room and requires thorough cleaning afterwards.
- 🚫 Water and foam compositions —deadly when extinguishing live equipment, use is prohibited.
Algorithm for extinguishing fire in different situations
Actions to eliminate a fire depend on the stage of fire development and the type of materials that caught fire. If the fire has only engulfed the outer plastic panel or power cable, you can try to knock it out with a stream of fire extinguisher. If the flame has already spread to furniture or curtains, the priority becomes immediate evacuation and waiting for professional firefighters.
If the compressor or condenser behind the unit catches fire, the situation is complicated by the presence of oil and possible refrigerant. When the insulation of the motor windings burns, a characteristic pungent odor may occur. In this case, it is important not to inhale combustion products of freon and oil, as they can form toxic phosgene gas at high temperatures.
☑️ Checklist of actions in case of fire
When using a fire extinguisher, you must hold the cylinder vertically and point the nozzle at the base of the flame, not the top of the fire. Movements should be sweeping, from bottom to top. If the flame cannot be put out within 10-15 seconds of active operation of the fire extinguisher, or if the smoke becomes too thick, you must immediately leave the room and close the door tightly behind you to limit the flow of oxygen.
⚠️ Attention: Do not open windows and doors wide in the room where the fire is occurring until firefighters arrive. The influx of fresh oxygen will cause a flash and a sharp increase in combustion (draft effect).
Danger of refrigerants and oil in the system
Modern and old refrigerators contain refrigerants and compressor oil in a closed circuit. In a normal state, they do not burn or burn poorly, but when the system depressurizes due to fire or mechanical damage, the situation changes. Some types of freons, when in contact with an open flame, can decompose to form dangerous compounds.
Compressor oil, used to lubricate the rubbing parts of the engine, is a flammable substance. If the insulation breaks down and the windings heat up to high temperatures, the oil may ignite. The burning of oil is characterized by a high temperature and Difficulty of extinguishing with water, since oil is lighter than water and will burn on its surface, spreading and increasing the area of the fire.
What happens to freon during a fire?
When heated above 250°C, refrigerants (especially old types) can decompose with the release of phosgene - a chemical warfare agent suffocating effect. Therefore, being in a room with a burning refrigerator without respiratory protection is deadly.
It is important to understand that if the back of the refrigerator, where the compressor is located, catches fire, there is a risk of explosion. Although modern systems are equipped with protection, the thermal effect of an open fire on the metal housing of the compressor and condenser can lead to a sharp increase in pressure inside the system and its rupture, flying fragments.
Typical causes of refrigeration equipment fire
Understanding the causes of a fire helps prevent its recurrence in the future. Statistics show that most fires occur due to electrical faults and not due to spontaneous combustion of products. Aging of equipment, improper operation and poor quality repairs are the main risk factors.
One of the common reasons is short circuit in the control circuit or in the windings of the compressor electric motor. This can happen due to power surges in the network, moisture on the contacts, or deterioration of the wire insulation over time and overheating. Also dangerous is a faulty starting relay, which can stick and not turn off the starting winding, causing it to overheat and ignite.
| Cause of fire | Mechanism of occurrence | Probable consequences |
|---|---|---|
| Wiring malfunction | Overheating of contacts, melting of insulation, sparking | Fire of plastic housing, transfer of fire to furniture |
| Start relay | Contact sticking, continuous operation of the starting winding | Combustion of compressor windings, smoke, burning smell |
| TEF (for No Frost) | Faulty defrost timer, heater overheating | Melting of the plastic evaporator box, fire inside the chamber |
| Power surge | Insulation breakdown of electronic components | Instant fire of the control board or motor |
Another reason may be a malfunction of the defrost system in models with No Frost. If the heating element (tubular electric heater) does not turn off in time due to a broken thermostat or timer, it continues to heat up even when there is no more ice. This leads to the melting of the plastic casing of the evaporator and ignition of the polymer materials inside the chamber.
Actions after extinguishing the fire and assessment damage
After the fire has been extinguished and the room has been ventilated (after the firefighters have arrived and given their permission), you cannot immediately turn on the appliances. Even if the refrigerator looks intact on the outside, irreversible changes may have occurred inside. Thermal exposure could damage the insulation of the wires, which is not visible from the outside, which will make restarting deadly.
It is necessary to call a specialist for diagnosis or dispose of the device if the damage is significant. Food that was in the refrigerator during the fire must be completely discarded. Even if they did not burn, they could have absorbed the toxic combustion products of plastic, rubber and refrigerants, making them unfit for consumption.
It is important to document the consequences for the insurance company if the property is insured. Photos of the damage, a report from the fire department and receipts for the purchase of equipment will help you receive compensation. However, it is worth remembering that insurance cases often require proof of the absence of violations of operating rules on the part of the owner.
⚠️ Attention: An attempt to independently restore a burnt-out refrigerator by replacing burnt wires or relays is strictly not recommended. Thermal effects change the properties of metal and insulation throughout the system, making further operation unpredictable and dangerous.
Prevention of fire hazards
To minimize risks, it is necessary to regularly carry out preventive inspections of equipment. Pay attention to the condition of the power cord: it should not be frayed, melted or have creases. The socket into which the refrigerator is plugged in must fit tightly around the plug and not heat up or spark during operation.
Do not allow the compressor to overheat. The back wall of the refrigerator must have free air access for ventilation. Dust on the condenser (grid at the back) also contributes to overheating, so it is recommended to carefully vacuum the back panel of the device once a year. This will reduce the load on the engine and extend its service life.
- 🔌 Socket control — eliminate the use of extension cords and tees for permanent connection of powerful devices.
- 🧹 Cleaning capacitor —remove dust from the rear grille for better heat transfer.
- 🔊 Reaction to sounds - humming, clicking or crackling may indicate a malfunction of the relay or motor.
Following these simple rules will allow you to operate the equipment safely. Remember that a refrigerator is a complex electrical appliance that operates under high pressure and voltage, and it requires careful attention and timely maintenance.
Is it possible to extinguish a burning refrigerator with water?
Only a completely de-energized appliance can be extinguished with water. If you are sure that the power is turned off at the panel and the cord is unplugged, water will help put out the flames. However, if there is any doubt about a power outage, the water will create a conductive bridge and cause an electric shock. In addition, water can damage surviving components and create dirt, which complicates cleaning.
What to do if the wire inside the wall catches fire?
If you see that the fire is not coming from the refrigerator itself, but from the wall or outlet, immediately turn off the electricity in the entire apartment through the switch. Do not try to extinguish a wall with water or powder yourself if the fire has already penetrated the wall structure. Call the firefighters, as hidden burning of wiring is very dangerous and quickly spreads inside the ceilings.
Is smoke from burnt plastic in a refrigerator dangerous?
Yes, extremely dangerous. When the plastic housing, wire insulation and internal components burn, toxic substances are released, including cyanide, carbon monoxide and chloride compounds. Inhalation of this smoke, even in small quantities, can cause severe poisoning, burns of the respiratory tract and loss of consciousness. It is impossible to be in a smoky room without a respirator.
