I would like to share with you some essential knowledge about home appliance safety in summer.

July is about to enter. Have you felt the "enthusiasm" of Father-in-law the Sun recently? Have you entered the mode of air conditioning, wifi and watermelon again! Summer home appliances have become a good helper in our daily life. But on the other hand, they also planted many "ticking time bombs".

Just a few days ago, the news that a reporter died of suffocation due to a fire in his home air conditioner made people sigh. After summer, accidents caused by the use of home appliances are not uncommon. Summer is the season when household appliance fires are most likely to occur. What safety issues should we pay attention to when using air conditioners, TVs and other household appliances?

Just some time ago, a woman in Guangzhou, Guangdong showed a video of a hair dryer igniting a flash explosion. It attracted the attention of netizens. The video showed that a woman was drying her hair when suddenly the hair dryer exploded without any warning. The woman was so frightened that she threw the hair dryer away and ran away holding her head. The child next to her was also frightened by this sudden scene and cried. . Fortunately, no one was hurt, otherwise the consequences would be disastrous. Many netizens speculated that the hair dryer may have been used for a long time and short-circuited during use.

Looking at it this way, summer is here, and the issue of safety in the use of household appliances must attract everyone's attention. So, what safety issues should everyone pay attention to when using electrical appliances?

Home appliances should not be "extended"

Everyone knows that food has a shelf life and daily necessities have a shelf life, but perhaps many people What you don’t know is that household appliances actually have a “shelf life”. In most people's minds, home appliances are "if they're not broken, don't replace them with new ones." They think that as long as they don't break down, they can be used forever. This concept of the previous generation may be more serious, and even if it breaks, it must be used. To sum up, it is three years of the new, three years of the old, and another three years of mending. But in fact, this is a consumer misunderstanding. Expired home appliances have many hidden dangers and can cause great danger to health. Home appliances that have exceeded their useful life not only run slowly and consume high power, but also have hidden safety hazards during use.

Generally speaking, home appliances have their own service life. For example, if the air conditioner is used for 8-10 years, the wiring inside the indoor unit may deteriorate. In addition, problems such as water leakage, poor cooling, or no cooling may occur, and power consumption will increase significantly. In air conditioners that have been in service for an extended period, the dirt accumulated for a long time will not only produce odor, but also breed bacteria, viruses, mites, etc. Long-term use can also easily cause respiratory diseases and affect your health.

Small household appliances such as the hair dryers mentioned above generally have a short service life, especially for many girls with long hair. The wire blows inside, causing a short circuit. If you turn on the maximum power of the hair dryer, it is best not to turn it on for too long to avoid burning out the internal parts.

Of course, for more detailed service life of various types of household appliances, you can refer to the "Safe Use Life of Household Appliances" series of standards released in 2020. However, the safe use period and product warranty period cannot be completely confused.

Be careful when using electrical appliances improperly and overloading them

Since the beginning of summer, high-power appliances such as refrigerators and air conditioners have been running for a long time, and electricity consumption has surged. Household appliances such as electric water heaters and washing machines have also been affected. The frequency of use is also increasing. Therefore, the safety of electricity in summer requires great attention. High-power appliances such as air conditioners, electric water heaters, microwave ovens, etc. should not be activated at the same time to avoid accidents caused by excessive line load. In daily life, you also need to be careful not to place cooling appliances such as refrigerators and air conditioners close to flammable and combustible materials.

Don't "abuse" power sockets

In addition, electrical appliances should be unplugged after use. Nowadays, many people do not have the habit of unplugging the power plug. Once the power plug of many electrical appliances is plugged in, it may not be unplugged for several months. For example, common mobile phone chargers, hair dryer plugs, etc. This practice causes electrical equipment to be powered on and waiting for power, which is also unsafe.

A few days ago, my colleague also recounted his personal experience: after blowing his hair in the morning, he did not turn off the gear and the power switch, and the hair dryer "played itself" at home for a whole day...

< p> Please do not pull the wire with force when plugging or unplugging the power plug to prevent the insulation layer of the wire from being damaged and causing electric shock. If the insulation of the wire is found to be damaged, it must be replaced in time to prevent leakage and injury to people.

So what should we pay attention to when using electricity in summer?

1. In hot summer weather, the human body sweats more, and sweat is conductive. Sweating hands Unlike the resistance of clean hands, under the same conditions, the possibility and severity of electric shock when a person sweats is far greater than normal. Therefore, you must be particularly vigilant when using home appliances in summer.

2. When the home is unoccupied for many days, the electrical power supply should be cut off. After deactivating electrical appliances, unplug them and minimize live equipment.

3. For electrical appliances that are frequently used in summer, such as electric showers, washing machines, etc., some practical precautions should be taken to prevent electricity, such as frequently using a test pen to test whether the metal shell is charged, and using qualified electric shock protection device (leakage switch), etc.

4. Be careful not to touch or test the inside of the power socket with your hands or conductive objects (such as wire, nails, pins and other metal products); and do not touch the power supply with wet hands.
