When you have children at home, hidden dangers that you usually don\’t notice become problems. Although the hidden danger will not cause immediate harm, it is like a bomb that ignites at an unknown time and has to be defused. The following three points may be the most easily overlooked behaviors in daily life, and they usually stay in the most inconspicuous positions. Machine-washable down jackets are prone to explosion. At the end of December 2016, when Ms. Wang from Harbin was washing her down jackets in a washing machine, the washing machine suddenly exploded. The down jacket and the washing machine were blown out of the passage of the drum washing machine. Ms. Wang managed to escape in time, but her 6-year-old son\’s eyes were damaged. Hence the injury. Why do machine washable down jackets explode? Mainly because ① the outer layer of the down jacket has poor air permeability; ② during the spin-drying process, air is generated by squeezing the clothes and the pressure is generated by high-speed movement. Generally, vertical washing machines and dryers are more likely to explode. There are certain conditions for down jackets to explode. So what kind of down jackets can be machine washed? ① There is a \”down jacket\” option on the washing machine, or the instructions allow cleaning ② The cleaning label of the down jacket indicates \”machine washable\” ③ To ensure safety, it is best to use a laundry bag to pack the desiccant when drying. Shaking when exposed to water may cause an explosion, CCTV reports Last year, a 5-year-old boy poured quicklime desiccant into a bottle and mixed it with water to blow bubbles. After shaking the bottle, it exploded. The splashed liquid burned the boy\’s eyes. In just two minutes, his right eye was damaged by the erosion of the alkaline liquid. blindness. There are many tragedies like this. In 2014, a 5-year-old boy in Jiangxi accidentally put desiccant into his eyes, causing burns to both eyeballs and eyelids, causing permanent vision damage, 0.2 in the right eye and 0.25 in the left eye. In 2012, a 6-year-old boy in Zhoukou City, Henan Province was eating snacks and playing with a desiccant bag when the bag suddenly cracked and white powder sprayed all over his face. After rescue, the child barely managed to save his left eye, but unfortunately he lost sight in his right eye. How to avoid desiccant damage? There are four main types of desiccants commonly used in life: quicklime desiccant, silica gel desiccant, montmorillonite desiccant, and fiber desiccant. What caused the above tragedy was quicklime desiccant, which is commonly used in food (because it is cheap). In order for the quicklime desiccant to explode, it must at least ① fully swell when exposed to water ② quicklime in a confined space is highly alkaline and extremely destructive, especially to the cornea of the eye. However, no matter what type of desiccant it is, there is a possibility of contact with skin and accidental ingestion during play, so children should avoid contact with it. When purchasing products containing desiccant such as food and medicine, throw away the desiccant immediately after unpacking it or place it out of the reach of children. Don’t ignore this point in your daily safety education. What should I do if I get quicklime desiccant on my skin? ① Rinse with plenty of water continuously for at least 15 minutes, and then go to the hospital. ② If it enters the eyes, rinse for at least 30 minutes. Pay attention to turning your eyes when rinsing, and then go to the hospital. What should you do if you swallow it by mistake? Quicklime desiccant: Dilute with water immediately orally, 10ml/kg body weight, no more than 200ml at most. Then take milk, vegetable oil, and raw egg white orally to protect the injured surface and prevent corrosion from deepening. Then go to the hospital. Silica gel desiccant: Silica gel is generally non-toxic and will not be digested and absorbed. It only needs to wait for it to be excreted from the body with stool.Used for special processing. Tempered glass self-exploded into slag, injuring many people. On November 28, 2016, 11-year-old Xiaoqiang was injured in the calf by the tempered glass door that suddenly burst while he was taking a bath. I had to go to the hospital overnight to get a tetanus shot and bandage the wound. The wounds on Xiaoqiang\’s body were all over 1cm. On January 26, 2015, a 6-year-old boy in Shenzhen suffered more than a dozen wounds all over his body from a sudden explosion of tempered glass in the bathroom. When the boy\’s mother heard the \”bang\” explosion, several pieces of broken glass were still inserted into her son\’s head… The explosion itself is a terrifying thing, and the explosion of tempered glass in the bathroom while taking a bath was even more shocking. Why does tempered glass explode? Tempered glass itself has a self-explosion rate of 1~3‰, which is an irreversible flaw. In addition to its own tempering degree, tempered glass may explode due to the following conditions: ① Improper use, push-pull closing too hard, etc. ② Improper installation, bumps and bumps during transportation and installation, resulting in uneven stress in daily use ③ Large temperature difference , extremely uneven heating on both sides of the glass ④ due to external impact, etc. How to prevent tempered glass from exploding? ① Keep an eye on the quality. Choose tempered glass products from big brands with quality assurance and high-quality after-sales service. Curtain walls, doors and windows can choose anti-scatter glass or semi-tempered glass. ②Affix explosion-proof film. Post an explosion-proof film of the same size in advance. The tempered glass with the explosion-proof film will not break into slag after it is damaged or self-explodes. It will stay in its original position in a finely broken and complete state. At this time, you can find a professional to deal with the aftermath.
