Note7 Battery Explosion Event Review
In the early morning of September 18, a netizen named “Chihuahua you” posted on Baidu’s “Note7” post bar that the coral blue version of Samsung’s Note7, the national bank version he purchased from jd.com, exploded. The netizen said, “sitting on the bed and playing with the mobile phone, the screen suddenly went black for no reason. The mobile phone was shaking. I felt something wrong and threw it away immediately. It really exploded.”
According to the photos posted by this netizen, the screen of the mobile phone in the accident has been partially burnt, which is similar to the situation of the foreign Note7 battery fire and explosion accident.
how should we give first aid when burns occur
Although the explosion of Samsung mobile phones did not cause serious injury to personnel, burns and scalds are also common in daily life, such as being accidentally scalded by boiling water and overheating the bath water temperature. What can you do when burns and scalds occur? How to give first aid? Jia Dacheng, a senior expert of Beijing Emergency Center and a well-known Weibo big V, mentioned in “120 doctors teach you first aid” that once a burn (scald) injury occurs, the following treatment should be carried out immediately:
First, get out of the dangerous environment and eliminate the injury factors
? Take off the burning clothes immediately; Or immediately extinguish the flame with water; Or quickly lie down and roll on the spot to extinguish the flame; Or cover the fire with a quilt or coat
? Don’t run or shout with fire to avoid respiratory tract burn or wind burn. Covering your mouth and nose with a wet towel can prevent the inhalation of toxic gas and smoke, as well as asphyxia and respiratory tract burns.
? The higher the position, the greater the smoke and poison gas.
Second, treatment of burn wound
? After burn, the most important treatment is to fully wash or soak the wound surface with 15-25 ℃ cold water (tap water can be used) for about 20 minutes as soon as possible, so as to neutralize the residual heat, reduce the temperature, relieve the pain of the wound surface to the maximum extent, reduce edema, avoid the further deepening of heat, promote healing, reduce the formation of scars, and reduce the scope of excision and skin grafting. However, it is not suitable to apply ice to avoid tissue ischemia caused by excessive contraction of blood vessels, which is not conducive to recovery.
? Do not prick the blister to avoid infection.
? Release the clothes in the water. If there is adhesion, use scissors to cut around the wound to prevent aggravating the damage; And take off the accessories such as watches, bracelets and rings to prevent swelling and affecting blood circulation.
? Never apply toothpaste, soy sauce, yellow sauce, alkaline flour, plant ash, etc. these substances can not cure burns, but can cause infection.
Third, strong acid and alkali burn
? Immediately dry them with towels, clothes and other cloth, and then rinse them thoroughly with plenty of cold water to avoid expanding the burn area.
? If strong acid, strong alkali or quicklime enters the eye, it needs to be washed carefully and thoroughly.
? If the digestive tract is burned by strong acid, take 200ml of milk, egg white, soy milk, edible vegetable oil and so on orally immediately. It is forbidden to take sodium bicarbonate orally, so as to avoid the perforation of digestive tract caused by carbon dioxide; Strictly induce vomiting or wash stomach to avoid perforation of digestive tract.
? If the digestive tract is burned by strong alkali, take vinegar, lemon juice, 1% acetic acid, etc. orally, or milk, egg white, edible vegetable oil, etc., 200ml each time, to protect the gastric mucosa. Strictly induce vomiting and gastric lavage to avoid gastrointestinal perforation.
Fourth, after the above treatment, cover the burn wound with sterile or clean cloth.
Fifth, if necessary, call the emergency number 120 and send to the hospital as soon as possible.
how to prevent burns
people at high risk of burn and scald
? Children aged 1-4 years old lack the ability to recognize the hazards of heat sources, and suffer upper limb scalds when they touch heaters, electric heaters, hot water bottles, etc. out of curiosity.
? The elderly, especially the elderly, are slow to move, slow to respond, have a reduced sense of temperature and lack the ability to avoid hazards, and are prone to scald at the contact part when contacting with heat sources.
? Patients with diabetes, stroke paralysis and Alzheimer’s disease can’t express their feelings in time and correctly except for their reduced ability to feel temperature and lack of ability to avoid hazards. Therefore, scalds can often not be found and treated in time until local infection or necrosis is found and sent to the hospital for treatment.
? Healthy people in sleep: after falling asleep, especially after entering deep sleep, healthy people’s reaction ability to the outside world decreases, and “chronic scald” occurs at the contact part when using hot water bags or heating kettles, that is, deep scald occurs when the temperature is not high but the contact time is long.
? Scalds in the kitchen: such as hot oil splashing, hot soup spilling, etc.
prevention of burns and scalds
? When eating hot pot, pay attention that the wires and plugs of the electric hot pot should not be placed in places easily accessible to children, so as to prevent children from tripping over the wires when playing, overturning the hot pot and causing scalds.
? Keep away from some inflammable articles such as bed sheets, furniture and clothes at home. Do not dry wet clothes on the electric heater at ordinary times. The surface temperature of the electric heater is high, which will affect heat dissipation and easily cause fire after covering the articles; Especially when the electric heater is on, don’t leave the child alone in the room.
? When using electric thermos, baby warmer and hot water bag, be sure to wrap them with cotton covers to avoid contact with human skin or warm the quilt first, and take them out when sleeping. When using an electric blanket, turn off the power before going to bed, especially for the elderly.
? Put high-temperature containers such as thermos at home at high places or places where children can’t easily touch them. Heat containers containing hot food, such as electric rice cookers, should not be placed on the ground or low. Hot soup should be kept away from children or served last. The length of the dining table towel should be moderate to prevent children from pulling the hot soup out of curiosity. If there are children in the family, it is safest not to lay table towels.
? Children should be told not to touch the red switch of the water dispenser. When parents drink hot tea or coffee, they should put down the child they hold. Otherwise, if parents do not pay attention to any action, they will easily pour hot liquid on the child.
? Try not to let children into the kitchen. When cooking in the kitchen, people do not leave or close the door to prevent children from breaking in suddenly. Put the handle of the hot pot towards the back wall of the stove as far as possible, so that children can’t easily touch it. Turn off the main switch when the gas is not in use to prevent children from imitating the ignition. When the child is not around or in the kitchen, take out food from the microwave oven. Baby food or milk heated in the microwave oven should be shaken and cooled for a while after being taken out.
? Try not to let children enter the bathroom, and keep the floor dry to prevent children from falling and overturning the hot liquid. Teach children not to touch the faucet of the bathtub, and try to keep children away from hot water sources when bathing.
? Ignition appliances, such as lighters and matches, should be placed in places where children can’t easily get them. Electrical sockets should be placed at a high place or covered as far as possible so that children can’t easily touch them. Check whether the exposed wires are damaged or obviously exposed. Liquefiers, gas stoves and pipes shall be regularly inspected and maintained. After taking a bath, open doors and windows for ventilation.
? Most of the scalds of children are scalded by boiling water, foot washing water, and bath water. Almost half of the children are scalded by bath water, which is often caused by the negligence of parents. When bathing children, we must remember to pour cold water first and then hot water. At the same time, we should test the water temperature by hand. Don’t leave the children alone in the bathroom.
? When setting off fireworks and firecrackers, children should be informed of the correct setting method, and it is best to have parents around.
what kind of family medicine can treat burns
The scald medicines commonly available at home are mainly Jingwanhong and various traditional Chinese medicine burn creams, which are suitable for mild scalds. Most of these traditional Chinese medicine ointments are oily ointments, which can prevent bacterial invasion and dispel putrefaction.
Mild scald caused by water or fire, only redness, pain, small blisters, no ulceration or slight ulceration. If the scalded skin is not damaged, the affected part can be immersed in clean water at a temperature of not less than 5 ℃ to reduce temperature, and the pain can be alleviated. The immersion time is about half an hour. Then apply the above ointment.
For slightly severe scalds caused by water or fire, blisters or ulcers, Jingwanhong ointment can be used for external use. Before using this medicine, clean the wound surface with normal saline, clean and disinfect the periphery of the wound surface with 75% alcohol, and then apply the ointment on the sterilized gauze block to cover the wound surface, then wrap it with sterilized bandage, and change the dressing once a day.
If the scalded surface is serious or does not improve after 1-2 days of medication, or the scalded area is red and swollen, or has a mild fever, it must be treated by a doctor.
It should be noted that if there is no scalding medicine at home, you can temporarily apply sesame oil or sesame oil to block bacteria. Never smear toothpaste or purple potion at will.
Summary: families must always have first-aid drugs in case of emergency. If the burn is mild, it can be treated by yourself. If the redness, swelling and fever are aggravated, you must go to the hospital for treatment.
