It's about to be the May Day holiday, it's hot, and many people will spray sunscreen spray and toilet water on their bodies when they go out, but if these insect and sunscreen sprays are not used properly, they are very likely to cause fire accidents.
On April 25, Hangzhou Fire Department conducted several sets of experiments to tell everyone how to prevent such accidents.
Many brands of sunscreen spray, insecticide spray, toilet water and other products were prepared at the experimental site, and firefighters wearing protective clothing successively pressed gold, pink, and white bottled sunscreen sprays, sprayed them into the air, and used an igniter to ignite the gas sprayed. The reporter saw that in addition to the white bottled sunscreen spray, other brands of sunscreen spray instantly ignited flames when they encountered an open flame. And the white bottled sunscreen spray also caught fire when it was lit with a lighter.
In the same experimental operation, the insecticide ignited a long tongue of fire after encountering an open flame, and the flame caused by the flower water was relatively small. Zhang Shengyu, a firefighter who participated in the experiment, explained that this is related to the dose of different spray presses, and the smaller the dose, the relatively milder the fire.
Firefighters then set fire to a garment that had never been sprayed, and the result was that it was not flammable. When the spray is applied to the garment and then the fire is lit again, the garment burns. Subsequently, firefighters simulated human skin with pork on the skin. When spraying the pork, immediately approach the pork with an igniter, and a slight flame ignites on the surface of the pork.
Zhang Shengyu said that these summer products contain flammable substances such as denatured ethanol, butane, isobutane, methrin, and permethrin, which will burn when exposed to fire. If the concentration of these flammable substances is too high in a confined space, it may cause an explosion when it encounters an open flame or electric spark. "So when applying sunscreen spray on the body in summer, don't go near the fire, especially boys who like to smoke, when applying sunscreen spray, don't smoke, the lighter ignites the moment, accidents may happen at any time. ”
Of course, in addition to the sunscreen and mosquito repellent products commonly used by young people in summer, many elderly people are also accustomed to using traditional mosquito coils at home, the maximum temperature of the mosquito coils after ignition can reach about 600 degrees, and the surrounding 1 cm can also reach about 100 degrees, which may cause burns when touching the skin, and can also burn mosquito nets, clothes, quilts, etc., which may ignite the surrounding combustibles for a long time and cause fires.
"We must pay attention to safety when using air conditioners, fans, mobile phones and other electrical appliances at home, and let the electrical appliances take a break after the 'long standby', so as not to overload the electricity, otherwise it is easy to cause overheating or short circuit faults and cause fires. Zhang Shengyu told reporters, "Volatile flammable gases such as toilet water and alcohol, the temperature in the car is too high, and it is also easy to ignite, as well as reading glasses, magnifying glasses and other items with convex lens effect, which are easy to ignite combustibles in the car for a long time." For electronic products such as power banks and mobile phones, batteries are prone to bulging in high-temperature environments and have a risk of explosion. ”
