Cold wave invasion, how to properly heat?

The Central Meteorological Observatory recently issued a yellow warning for cold waves. From the 13th to the 16th , a large range of strong winds and rain and snow will occur from north to south in most of the central and eastern parts of China. In winter, the weather turns cold, and “heating artifacts” such as air conditioners and electric heaters come in handy. However, these heating devices bring about warmth and if used improperly, there are potential safety hazards. In this issue, China Rescue Equipment specially inventories the common accidents in winter heating to see which heating methods are not desirable.

Type 1 accident

High temperature dehydration

[Case] January 17, 2013, Guangzhou City, Guangdong Province, a 9-year-old boy woke up in the morning chapped lips, his face dark red, nosebleeds. After a hospital examination, the boy discovered that the boy was using a heater throughout the night and caused the nasal mucosa to dry, red, and swollen, causing nasal bleeding.

[Cause] Many people in winter are over-reliance on a warm environment. However, according to experts, the use of heating equipment may cause various degrees of damage to body organs. If you use it for a long period of time, it can cause excessive water loss and cause problems such as itchy skin and nosebleeds.

[Measures] When using heating equipment, pay attention to the control time and avoid being in an excessively warm environment for a long time. During the use of heating equipment, pay attention to drink plenty of water, eat more fresh fruits and vegetables, and eat less spicy foods such as spicy food. Increase the indoor humidity, for example, put a wet towel on the radiator, let the water in the towel slowly evaporate, or sprinkle some water on the floor or in the flowerpot, or use a humidifier to keep the room at a certain humidity.

Type 2 accident

Low temperature burns

【Case】 Ms. Chongqing, for fear that her 3 -year-old son was asleep at night, put a “warm baby” across her pajamas for three days and nights. The evening of January 4, 2016, the woman found the back of the child's skin is very red, but also many long small blisters, and quickly bring the child for treatment. After diagnosis, the doctor found that the child was suffering from a low temperature burn caused by prolonged exposure to heat and was seriously injured.

[Cause] The so-called low-temperature scald refers to a burn caused by a long-term exposure to a low-heat object that is higher than body temperature. Low-temperature burns mostly occur on cold winter nights . On the one hand, people's skin sensitivity to thermal reactions decreases during the winter. On the other hand, people are still in deep sleep during hot periods, and are not awakened by the pain. . Some special groups, such as the elderly, children, or people who have suffered from poor circulation due to illness, have a slow feeling of heat and pain and become the main victims of low temperature burns.

[Measures] When using heating equipment in winter, it is appropriate to feel the warmth. If you feel hot and hot skin, it means that the distance is too close, there is the danger of being burned. It is best to use it intermittently. Change the location of the heating equipment often, otherwise it is easy to cause local burns. Heating equipment should be suspended during charging, and unplug the power plug immediately after charging. Hot water bottle or hand warmer must choose the regular manufacturers, have a certificate. When using a hot water bottle, be sure to tighten the cover to prevent hot water out of the scald.

In addition, the low-temperature burns are mostly scald, and the pain is not very obvious. It can be washed with tap water for the first time. If it is slightly more serious, apply cold compresses or apply some ointment. The time for cold compressing is not clearly defined, usually around 10 minutes until the pain is significantly reduced. What needs to be reminded is that if the scald area has become purulent, do not deal with it yourself and you should go to the hospital promptly.

"Heating artifacts" use this way

Air Conditioning: Pay attention to window ventilation

The air conditioner should be thoroughly cleaned before use to avoid excessive dust and induce upper respiratory tract infections. In addition, during the air-conditioning period, pay attention to window ventilation, fresh air for the room. In the setting of the temperature, try not to set the temperature too high. On the one hand, excessive temperature wastes energy. On the other hand, if the temperature difference from the outside is too large, it can easily cause a cold.

Electric heater: The service life is no more than six years

When buying electric heaters, look for regular businesses to see if there is a 3C certification. During use, do not cover the radiator with clothing to avoid fire. Electric heaters have a certain useful life. Generally, it is better not to exceed six years. The longer the age, the less safe.

Electric blanket: scrubbing with a soft brush

When using electric blankets to warm up, be careful not to use electricity all night. Electric blankets are not allowed to be folded. If damaged, repairs must be done by professionals. Electric blankets should be checked for leakage before they are used. Once a fire breaks out, first cut off the power supply and try to extinguish the fire. If you want to clean the blanket, do not rub it with your hands, otherwise it will damage the insulating layer of the heating wire or break the heating wire. The correct method is to use a soft brush to dip in water and gently dry it before use.

Type 3 accident

Heating causes fire

[Case] November 2, 2016, Jinan City, Shandong Province, a residential home, due to a short circuit caused by electric blanket fire, killing two elderly people died.

[Cause] During the operation of the heating equipment, the temperature of the equipment itself and its surroundings are relatively high. If it is too close to a flammable object such as a sofa or bedding, the possibility of a fire will greatly increase.

[Measures] In daily life, heating equipment must be kept away from flammable and explosive materials. When people leave, remember to cut off the power. If you use the electric blanket for heating at night, it is best to open it for a period of time before bedtime and close it before going to bed to avoid accidents at night.

In addition, the quality of heating equipment currently on the market is uneven and many “three non-products” products are blended into them. The use of these inferior products is not standardized, and accidental combustion or explosion accidents are likely to occur during use. When buying heating equipment, pay attention to products with good reputation and certain popularity. In addition, we must also pay attention to checking the manufacturer, site, and brand of the product, and keep the purchase document properly in order to report the problem to the relevant organization.

Type 4 accident

poisoned by carbon monoxide

[Case] November 4, 2016, when two elderly Guiyang City, Guizhou Province warming himself at home, because the windows closed cause carbon monoxide poisoning, was found after family members rushed to hospital, but fortunately out of danger.

[Cause] In order to keep out the cold in winter, some residents will close the doors and windows and burn charcoal or coal at home to heat up. However, due to insufficient oxygen supply, these materials will generate a large amount of carbon monoxide gas in the case of insufficient combustion, resulting in a large accumulation of carbon monoxide during indoor ventilation and causing serious damage to the body's tissue cells, especially the cerebral cortex. Carbon monoxide is colorless and odorless. Once inhaled, people often feel nauseous, weak limbs and even syncope, and are seriously at risk of life.

[Countermeasures] Carbon monoxide poisoning accidents often occur every year due to the burning of coal or coal-fired heating. Residents are advised to avoid such heating methods as much as possible. If you really want to use this method of heating, you must pay attention to indoor ventilation, while avoiding being in such an environment for a long time.

Once someone is found to have carbon monoxide poisoning, and the poisoned person is still awake, he must quickly open the doors and windows, move it to a well ventilated, fresh air, and he can usually heal himself. The moderately and severely poisoned persons are generally unable to save themselves. The rescue personnel, with their own protection, quickly move the poisoned person to a well ventilated place and pay attention to keeping warm. If the patient does not breathe, he should first remove the patient's oral secretions and vomitus, and immediately implement artificial respiration, as soon as possible to the hospital for treatment.
