How to use electrical equipment safely during storm season

(Baonghean.vn) - During the rainy season, electrical appliances in the home can leak due to moisture from the walls or rainwater, leading to many dangers. Below are some notes to ensure safety when using electrical appliances.

Check the electrical system in the house before it rains.

To avoid leakage and short circuit when the wall is damp or flooded due to storms, you need to check the electrical wiring in your home if it has been used for many years. It is necessary to install separate circuit breakers or circuit breakers for each floor to make it easier to control the power supply.

Turn off power to unnecessary devices

When there are signs of unusual rain and storms, it is necessary to check all electrical equipment in the house and immediately turn off unused power sources. Computers, phones that are charging, televisions, electric kettles, etc. are all devices that are susceptible to electrical induction, so there is a high possibility of damage or even explosion in the rain. The power supply to outdoor electrical equipment (signs, billboards, etc.) also needs to be turned off when it rains heavily or is windy. In addition, before leaving the house, you should turn off electrical equipment that is not used regularly to ensure safety.

Pay attention to underground electrical wiring in the house

Currently, most families today use underground electrical wiring in the house. However, when it rains and floods for a long time, the walls of the house are easily soaked with moisture, leading to the situation of seeping into the electrical wiring, especially the wiring that has been used for a long time, leading to leakage and short circuit.

In addition, electrical connectors are also a danger as they are susceptible to water and we cannot control the moisture condition.

To avoid this situation, it is best to pay attention when designing underground power lines that the wires and electrical outlets must be high up, not placed in low positions that can be flooded or easily damp during heavy rain.

If the electrical system in the house has been used for many years, when the flooding is severe and for a long time, the user should turn off all circuit breakers to avoid danger.

After rain or flooding, check electrical wiring and sockets to see if water or moisture has affected them. If so, dry them before turning off the circuit breaker to use electricity.

Do not use low-positioned sockets.

This is one of the lurking dangers during the rainy and stormy season, especially when your family is located in a flooded area.

At this time, it is best not to use and should cover the electrical outlets in this low position. If you want, use the electrical outlets in a higher or drier position. It is important to note that the electrical lines should also be placed in a high position to avoid dangerous electrical leakage when exposed to water.

Install electrical equipment in high and dry places

It is necessary to arrange the installation of electrical wires, electrical sockets, and electrical equipment in the house at a higher position than the water level when flooded to avoid moisture and install suitable circuit breakers (ELCB). In case the electrical equipment is damp or soaked in water, it is necessary to immediately turn off the power and dry the equipment.

Grounding for household electrical appliances

Many large household electrical appliances are inconvenient to move to dry areas when flooded: washing machines, water heaters, dryers, cookers, etc. Therefore, after rain or humidity, users should also carefully check these devices before using. It is best to dry the wires and sockets before using.

In addition, users should also connect separate ground wires for these devices (washing machines, water heaters) to ensure safety during use.

Use lightning arrester

Currently, there are many products of lightning rods, lightning protection rods on the market... These are very necessary devices and should be installed to ensure that electrical equipment in your home does not have problems.

* In addition, thunderstorms often occur during the rainy season. Therefore, the risk of danger to human life and property damage due to lightning strikes is very high.

The extent of damage depends on the strength of the current and the distance from the lightning strike. Most home appliances are damaged by lightning that travels from power lines rather than by a direct strike, especially in urban areas.

Therefore, when there is a risk of lightning, it is necessary to apply the following lightning prevention measures:

- For antennas, telephone lines:To limit damage, it is necessary to quickly cut off the power supply when a thunderstorm begins. In addition, it is possible to equip the telephone lines with surge protection boxes.

- For household appliances such as televisions, washing machines, refrigerators, air conditioners:Unplug all electrical appliances in the home and all electrical appliances must be grounded to avoid electrostatic discharge due to lightning induction.

- For computers, modems:You need to unplug the power cord and internet signal cable from the modem, or you can buy a lightning protection device for each network connection to your personal computer./.
