These items also need to prevent heatstroke and cool down, as well as high-temperature safety knowledge posts! Faced with "baking" and experiencing exposure to sunlight, floral dew, and high temperatures

In recent days, high temperatures have persisted in many areas. Faced with baking tests, these items in daily life also need to be cooled down. Learn these safety knowledge under high temperature together ↓↓↓

01

Knock on the blackboard

Household appliances also need to prevent heatstroke

The temperature remains high

The electricity consumption in homes and business premises has sharply increased

Electrical appliances such as air conditioners and refrigerators bring us coolness

But not paying attention

They may also suffer from heatstroke and become irritable

These small strategies can help you prevent problems before they occur ✅

After "long standby", let the electrical appliances rest for a while

In high temperature weather, there are more fires caused by electrical reasons. Some electrical equipment and circuits operate under overload for a long time, which can easily cause overheating or short circuit faults and lead to fires. High power electrical equipment such as air conditioners should not be used for too long. Both work units and households need to use electricity safely, avoid pulling and connecting wires randomly, and avoid overloading electricity usage.

Pay more attention to old sockets and wiring

Residential households and business premises may have some equipment and circuits that have been out of repair for a long time. When sockets are not in use, they should be cut off as much as possible and should not be used for a long time. If encountering old sockets and wires, pay more attention and replace them in a timely manner to avoid short circuits and fire hazards.

Remember to find a cool place for the appliances as well

In summer, the sunlight is strong, and household appliances should be placed in a place without direct sunlight or in a dark place to maintain good ventilation.

Do not touch live equipment with wet hands

Develop good habits of using electrical appliances. Do not come into contact with live equipment and appliances when hands are wet; Lamp heads, sockets, switches, etc. should not be exposed to water.

scorching summer sun

Driving with skills

The continuous hot weather and higher temperatures on the road surface pose a significant challenge to driving vehicles. So how to scientifically avoid the heat and cool down while ensuring driving safety during summer?

Attention! Do not put these items in the car

Previously, the fire department conducted relevant simulation experiments under high temperatures. Under the scorching sun, the temperature inside the sedan quickly rose to 60 ℃.

The firefighter used a thermal imager to measure the temperature of the dashboard under exposure to sunlight, but it exceeded 80 ℃.

The fire department reminds car owners to minimize vehicle exposure time in summer and not to place the following four types of items in the car:

Lighters, sunscreen spray, carbonated drinks and other canned goods with pressure are easy to expand when heated.

Floral water, alcohol, etc., can evaporate and produce flammable gases. If the temperature inside the car is too high, it can reach the ignition point or easily ignite when exposed to open flames.

Items with convex lens effects such as reading glasses, magnifying glasses, and bottled water can easily ignite combustible materials inside the car due to prolonged focusing and heating.

Electronic products such as power banks and mobile phones are prone to bulging in high temperature environments, posing a risk of explosion.

Vehicle tire pressure is difficult to withstand as road temperature rises

In addition, as the road temperature rises, problems such as tire blowouts often occur in cars. When driving, car owners should pay more attention to the condition of the vehicle's tires. Emergency braking should be minimized as much as possible to avoid exacerbating tread wear. In addition, non-standard tire pressure can also lead to excessive tire wear, resulting in tire blowouts.

Do not directly spray water on the tires to cool down after continuous high-speed driving

After driving on the highway for a few hours in summer, it is important to stop and rest in a suitable shade to cool down the tires. However, do not directly spray water on the tire to cool it down, as it can cause cracks in the tire and shorten its service life.

"Summer essentials" not only include items

And there are safety guidelines behind it

In summer, many people will choose cool spray, but the wrong use of this kind of "heatstroke prevention artifact" will have a great potential safety hazard. A fireman used a transparent box to conduct a simulation experiment. After spraying a large amount of cool spray in the box, he threw the open fire into the box, and the whole box was immediately surrounded by fire.

In addition, it is important to pay more attention when using mosquito repellent products such as insecticides, toilet water, and mosquito coils at home in summer.

In insecticides, some components belong to combustion promoting substances, which are easy to burn when exposed to open flames and burn violently.

At present, various flower dew and mosquito repellents sold on the market are mainly composed of ethanol, water, etc. When using, it is also important to keep away from sources of fire.

The lit mosquito repellent incense should be placed on a metal bracket and not next to flammable items such as wooden benches and bed sheets. When mosquito coils are smoldering, the highest temperature at the ignition point can reach 700-800 ℃, which can ignite flammable materials such as mosquito nets, clothes, and cardboard boxes.

Scientific sun protection and heat relief in the scorching summer

Both safety and coolness are necessary
