Shanghai residents forgot to turn off the fire when they went out to cook soup. What fire hazards may exist at home?

Household appliances are overloaded with electricity. Many families often use several appliances at the same time, and many appliances work 24 hours a day. After long-term use, the heat dissipation function of household appliances is weakened. Once the power supply is used carelessly or the appliance is overloaded, the lines will overheat, which will easily lead to short circuit, fire and other failures. In particular, some electrical appliances are prone to explosion and fire due to aging, long use time and poor ventilation conditions.

Throw cigarette butts about. Some people like to smoke in bed and on the sofa to refresh themselves. Usually, people fall asleep before they stop smoking, and cigarette butts fall on flammable items such as bedding, mosquito nets and sofas, causing fires. Smokers are particularly dangerous. Most of these fire accidents occur in construction sites, rental houses and wooden string factories.

Open flame lighting. Household electricity consumption suddenly rises in winter. In winter, in addition to power cuts, it is also prone to power accidents and sudden power outages. Due to power failure, people often use candles and other open flames for lighting, which greatly increases the fire hazard. Sometimes, because the electrical plug used after power failure is not unplugged in time, once the power supply is connected, it is easy to get hot and catch fire after long-term power supply.

Flammable and explosive materials. Some inflammable and explosive articles used or stored at home are easy to burn and explode, causing fires. Such as natural gas, liquefied petroleum gas, gasoline, paint, perfume, mousse, etc. Improper preservation or misuse is very dangerous. Lying on the sofa or bed smoking and littering cigarette butts are bad habits of many smokers. Carelessness can easily lead to fire. Attention smokers. Improper use of electrical appliances or their own quality problems and untimely maintenance make electrical appliances "sick" and bring different degrees of threats and hidden dangers to family fire safety belts. Some ground wires have been trampled for a long time, which has hidden dangers. Some families use flammable materials such as gasoline, kerosene and alcohol to ignite. A little carelessness can easily lead to fires and fire accidents. Therefore, when you go out at ordinary times, you must pay more attention to these security risks and take precautions in time.
