Don't light mosquito repellent incense or use coal

  • Detail

Just after applying toilet water and nail polish, don't point mosquito repellent incense and use a gas stove

summer is approaching, the weather is beginning to be hot, mosquitoes are gradually increasing, and toilet water and other summer hygiene products in supermarkets are selling well. Recently, a Weibo about the flammability of daily necessities such as toilet water has attracted the attention of many friends. Many of the liquids mentioned in it are "guests" on the dresser of female friends. Some friends even joked that the female dresser seemed to become a "hidden fire source". In order to verify the flammability of these liquids, combustion experiments were carried out on several daily necessities mentioned in Weibo

microblog toilet water and other liquids are flammable. Some users have been burned

"are you familiar with common inflammables in life?" Recently, the official Weibo of Shanghai Fire Sina released a service message, saying that toilet water, perfume, nail polish, gel cream, mosquito repellent water and insecticides are inflammables, and open flames near mosquito repellent incense, cigarette butts, candles and so on will be lit. Among them, the toilet water contains 70% - 75% alcohol, and its ignition point is only 24 ℃! The use and storage should avoid fire sources, and it is strictly forbidden to expose to the sun. The apparent consumption of domestic crude steel has decreased year by year since 2014

this Weibo was quickly forwarded more than 1400 times, with more than 200 comments. Many friends shouted their luck. Many people have had the experience of wiping toilet water, lighting mosquito repellent incense or cooking close to an open fire. Fortunately, there was no accident

how terrible is the toilet water once it burns? According to media reports, in 2010, a boy in Dongguan, Guangdong Province, Xiaohao smeared toilet water and played in the living room. A meter away, his brother playing with a lighter accidentally "lit" the toilet water Xiaohao smeared on his body, causing burns to his hands and face, and finally sent him to the hospital's serious illness ward for treatment. In 2011, a mother in Shenyang lit a mosquito repellent incense in order to repel mosquitoes to her baby. It was not enough to spray flowers and dew alone. As a result, in the middle of the night, the unburned mosquito repellent incense ignited the bed sheet, and a string of blisters were burned on one of the baby's hands. When seeing a doctor, the doctor told parents that if toilet water was sprayed on the child, the open fire might burn the child's skin all over, and the consequences would be unimaginable

[experiment · picture and truth] toilet water burns most thoroughly, and nail polish burns most violently

toner gel water combustion index ☆

in order to verify the flammability of toilet water and verify whether other daily chemical products mentioned above are flammable, express has carried out combustion experiments on these liquids

several different brands of toilet water, perfume, nail polish, gel water and toner were randomly purchased, and 10ml of them were sampled and poured into a beaker to prepare for the experiment

experimental method: take a cotton swab about 10 cm long and immerse it in the sample liquid. After fully immersing the cotton swab, ignite the soaked cotton with a lighter and put it into a beaker containing the liquid sample to observe its combustion

among them, the same experiment was carried out on toner and gel water respectively. The results showed that the cotton swab dipped in the sample did not burn, and the cotton swab did not react after being put into the beaker. Also try to put the sample in the Petri dish and ignite it directly with fire. The metallic paint effect and pearlescent effect have high requirements for the design. They also have no response and cannot be touched at all

[analysis] the sample does not contain alcohol, but you should be careful when using it

the toner and gel used in the experiment cannot burn, and there are no inflammables such as alcohol in the selected sample components. However, there are still many toners in the market that contain alcohol. In the process of purchase, use and storage, the instructions of these products should prevail

toilet water combustion index ★★★ ★

as soon as it contacts the flame, the cotton soaked in the toilet water soon ignites a blue flame. Put the cotton swab into the beaker and ignite the toilet water in the beaker through the flame. In less than two seconds, a yellow flame sprang up in the beaker, and the flame became stronger and stronger. It blackened the inner wall of the beaker and once jumped out of the container. Soon the cotton swab was burned into several pieces and fell on the bottom of the beaker, and the yellow flame gradually went out. At this time, the remaining toilet water at the bottom of the beaker is still making a "prick prick" sound. Look carefully, the surface of the toilet water is flickering with a faint blue fire, and the temperature of the beaker wall is very high. Five minutes later, all the remaining toilet water was burnt out, and the combustion finally stopped. In the beaker, there is only a circle of light green marks

[analysis] the alcohol content is high, and the flower dew is very flammable

it is understood that the alcohol concentration of the flower dew is generally 70% - 75%, which is easy to penetrate into the bacteria, and has strong disinfection and sterilization effect. See, the attention column on the toilet water bottle will specially remind that toilet water should be used and stored away from fire. Some toilet water instructions will also indicate that the storage of toilet water should be placed in a cool place as far as possible, not exposed to the sun. In addition, children should use it after diluting it five times. Try not to let children use and play with toilet water alone

nail polish combustion index ★★★

nail polish is more viscous than other experimental liquids, and sticks to the beaker wall and bottom after pouring into the beaker. Cotton swabs dipped with nail polish burn more violently and the flame is obvious. After the cotton swab was put into the beaker, the flame quickly jumped up and made a "crackling" sound, accompanied by a pungent burning smell. In less than three seconds, the whole container was full of fire, which was very frightening. After burning for nearly a minute, almost all of the nail polish stuck at the bottom of the beaker was burnt to a scorched black shape, and the fire was gradually extinguished. At this time, it can be seen that the container wall is also blackened, and the remaining nail polish sticks to the bottom

[analysis] nail polish belongs to flammable and dangerous chemicals

the nail polish used in this experiment is not labeled with ingredients, and most nail polish sold on the market is basically not labeled with ingredients. Most nail polish bottles will be printed with the "flame" flammable sign to remind you to avoid fire when using

it is understood that nail polish, also known as nail varnish, is generally prepared by mixing nail polish base material, toluene, ethyl acetate, butyl acetate, nitrocellulose and oil soluble pigments in a certain proportion, and the finished product contains 70% - 80% volatile solvents. Among them, nitrocellulose is prone to spontaneous combustion in the air, and nail polish is a flammable and dangerous chemical

perfume combustion index ★★★

chose a brand perfume, dipped in the cotton swab of the sample and lit it several times, and the fire turned yellow. After the cotton swab was put into the bottom of the beaker, no open fire was seen for more than ten seconds, only the sound of "stabbing" was heard. Perfume has many bubbles as if it were boiling. After a while, the surface of perfume glowed blue with more and more bubbles. Then the flame began to jump up and instantly turned into a yellow flame. After burning for about a minute, the flames gradually went out. Perfume did not burn completely, and a circle of pink marks remained at the bottom of the beaker

[analysis] perfume is inflammable and explosive. If it exceeds 49 ℃, it may explode.

perfume contains alcohol, which is inflammable and explosive. Generally, the content of essence is 10% - 30%, and the rest is wine essence. It is understood that the spices used to prepare essence are natural fragrant flower essential oil and natural animal spices, and the solvent is pure alcohol. It can be seen that the alcohol content in perfume is very high

it should be noted that most people like to place perfume in the car, but the volatilization of car perfume will produce a flammable gas. The critical point of explosion is 49 ℃, and explosion may occur in the high-temperature exposure environment for a long time. If the sun shines for 15 minutes in summer, the temperature in the closed car will reach 65 ℃, so be careful

tips: keep dangerous goods properly

summer is coming, and the details that are not noticed in many families are likely to bring hidden dangers to citizens' daily life. In summer, many families will light incense or electric mosquito repellent incense before going to bed. With the brain of the experimental machine, the incense burner is small, but the temperature of the mosquito repellent incense flame core is as high as 200 ℃ to 300 ℃. Once encountering inflammables such as cotton cloth, paper and wood, it is easy to cause a fire, and encountering inflammables and explosives such as toilet water, perfume, nail polish, the consequences are unimaginable. However, electric mosquito repellent incense has potential safety hazards due to its long-term power on state and improper use

it is understood that daily necessities such as gel water, automobile perfume, electric mosquito repellent incense and antiperspirant liquid are either flammable and explosive or contain chemical components. If an accident occurs due to the failure to follow the precautions and use methods indicated on the product, the consumer will bear the main responsibility. Therefore, people must pay attention to details in the process of keeping, carrying and using dangerous daily necessities


1 Check whether the product is qualified, and carefully read the instructions and precautions before use

2. Dangerous articles of daily use with pressure should be prevented from falling and squeezing with hard objects

3. Keep dangerous daily necessities in a cool place, not in a place easily accessible to children, not close to fire sources, heat sources and other heating bodies, and not heated or exposed to the sun

be careful when putting these items in the car.

in addition to the perfume and other liquids mentioned above, there are also some things that should not be put in the car in summer


drivers who like smoking often put lighters on the dashboard after lighting cigarettes. There is liquid butane in the portable lighter, and the internal pressure will increase after long-time exposure. It is easy to explode under friction, extrusion and collision

reading glasses

reading glasses belong to convex lenses, which are similar to the principle of magnifying glasses and are easy to gather light together. If you put reading glasses in the car, the light will gather at a point for a long time, which will raise its temperature and easily cause a fire

carbonated beverages

carbonated beverages containing carbon dioxide gas, such as coke, are easy to expand under high temperature and cause cracking. It is best to choose some paper packaging or gas free juice drinks

if the sun is strong, problems will occur due to excessive temperature, and even lead to explosion
