Effective ways to prevent fires due to electrical short circuits
In this article, Dong Nam Fire Protection Company shares ways to prevent fires and explosions caused by electrical short circuits. Currently, house fires are happening frequently with increasing damage, so equipping yourself with knowledge about fire prevention and fighting is extremely necessary. Let's look at ways to prevent electrical short circuits and fires right below.
- Short circuit is the first cause that easily leads to fire and explosion. To avoid risks, during the process of installing an electrical system at home, you need to note the following:
Electrics wire
- Before choosing an electric wire, you should clearly understand the parameters recorded on the wire such as cross section, copper core, number of copper wires, voltage, current... to calculate and select the correct load current. to choose the appropriate conductor.
- The electrical conductor must have a cross-section sufficient to allow the current to pass through the wire to be larger than the source and load currents, at least double to avoid overload. Do not choose a conductor with a current smaller than the load current. because it can easily cause fire, explosion or short circuit.
- If you want to check the quality of the wire, count the number of core strands exactly as recorded on the outside of the wire's sheath. If the number of fibers counted is not enough compared to the number of fibers recorded outside, the safety of the wire is not guaranteed.
- Good quality copper wire inside is reddish yellow, shiny and soft. On the contrary, if the copper wire is of poor quality, it will have a yellow-black color and will break easily when bent. It is best to choose to buy electrical wires from reputable manufacturers.
- You must not use bare wires, but must use good quality insulated wires and place them inside insulating pipes.
- Conductors, if used underground, must have at least 2 layers of insulation and must be threaded in fireproof plastic pipes.
- Do not let the power cord touch the iron, touch the air conditioner block, do not let the power cord near the stove or gas stove. Heat-generating electrical appliances such as irons, electric stoves, and gas stoves should not be placed near flammable objects or substances to avoid ignition upon contact.
Electric circuit breaker
- Each family must install a circuit breaker, circuit breaker, or quick power-cut relay behind the galvanometer, at the beginning of the main line in the house or at the beginning of each auxiliary wire branch.
- For safety, you should also install fuses in front of electrical outlets, so that when there is a short circuit or overload to avoid the risk of fire or explosion. -
All circuit breakers and fuses must have covers. When detecting places where the electrical wire has peeling insulation, it must be replaced immediately, and the connections are tightly wrapped with tape.
- Regularly check the automata. If the automaton is hot and making noise, replace it immediately.
- When repairing electricity in the house, you must cut off the circuit breaker and notify everyone so that the electricity does not turn on unexpectedly. It is best to ask someone with technical expertise in electricity to do the repair to avoid the risk of accident or short circuit causing fire after closing the circuit breaker.
- In addition, you should remember not to plug multiple devices into the same electrical outlet to avoid overloading, which can easily lead to a short circuit. - When using hand-held electrical equipment such as hair dryers, massage machines, grinders, drills, etc., you must wear insulating gloves to avoid shock if there is an electric leak. Turn off the power when moving plugged-in tools.
- And the important thing that cannot be overlooked is that you need to carefully read the electrical safety instructions for household appliances such as refrigerators, televisions, washing machines, microwaves, pumps... Devices with Metal enclosures must have a ground wire.
- Every time you leave the house, you must turn off all electrical equipment you are using. It is best to cut the main circuit breaker because electrical equipment that operates for a long time can easily generate heat and cause a fire. How to handle an electrical short circuit that causes a house fire
- An electrical short circuit leading to a house fire is something no one wants. But to avoid risks, each family needs to be equipped with knowledge about using electrical equipment safely to minimize damage, if any. - In case of an electrical short circuit causing a fire, it is necessary to immediately cut the circuit breaker and alert everyone to exit the house. If you are sure no one is trapped in the house, use a fire extinguisher to put out the fire. At the same time, pre-install the phone number 114 into your phone so that in case of need, you can call the fire police for assistance.
- Install smoke alarms in many locations in your home so that when an incident occurs, you can completely eliminate the risk of fire in your home. You should check the fire alarm batteries regularly to ensure your smoke alarm is always working properly. Usually you should change the battery once every 6 months.
- Never use water to extinguish fires caused by electrical short circuits. While waiting for firefighters to arrive, sit low to avoid breathing in smoke. If your clothes catch fire, roll around on the ground to extinguish the fire.
- You and your family members need to discuss in advance a plan to escape the fire, including getting out of the house and gathering in a certain location. And don't forget to equip a CO2 fire extinguisher to extinguish the fire.
- If someone in the house is burned by electricity, it is necessary to soak the burn in cold water and then cover it with a clean, dry cloth. If the burn is large, use a dry, sterile cloth to cover the burn and take it to the emergency room immediately! Electrical burns will cause damage to the victim's skin, muscles and bones. To prevent the victim from being shocked by electric burns, let the victim lie down on the ground with their feet elevated. Never try to remove burned pieces of clothing from burned skin.
