There are hidden safety hazards in improper use of mosquito -extinguishing products. Experiments tell you

Summer mosquitoes are also raging, and citizens will buy mosquito coils, mosquito repellent, electric mosquito auctions and other mosquito repellent products to repel mosquitoes. If these mosquito repellent products are not used properly, it may also bring hidden safety hazards.

On August 2nd, the Fire Rescue Brigade of Beilun District specially conducted several groups of mosquito repellent products fire -fighting experiments to take a look at what would happen if the mosquito repellent supplies were not used correctly.

experiment one:

The power of mosquito coils can reach 130 ° C high temperature around the fire

A firefighter was arranged at the experimental site to ignite mosquito coils, and then covered some mosquito nets into the mosquito coil plate to simulate the mosquito nets to encounter mosquito coils. In about a minute, a small amount of white smoke was seen under the mosquito nets, and the mosquito nets were quickly burned, and the surroundings were black, but it did not spread away, but there was a small hole.

Considering the influence of the material and time factors of mosquito nets, the firefighters conducted the next experiment and covered the sheets to the mosquito coil plate to simulate the mosquito coils when they touched the sheets. Black smoke was raised under the sheets, and it was gradually burned. The surroundings were black. Nearly 7 minutes, the sheets were directly ignited, and the fire spread quickly. The safety officers next to them quickly extinguished the fire extinguisher.

The fire supervisor of the fire rescue brigade of Beilun District's fire rescue brigade takes care of the letter to explain that mosquito coils are mainly composed of sticky wood powder, charcoal powder and drugs. When the fire is burning, the maximum temperature of the fire can reach 700 ° C -800 ° C, and 1 cm around the fire point is 1 cm around the fire point at 1 cm around the fire point at 1 cm around the fire point. It can reach 130 ° C high temperature, and can lead the burning of mosquito nets, cotton, sponges, clothes, paper and other flames and fires. Although the mosquito net experiments have not spread, it also shows that there are hidden fire hazards. When you are light -hearted, when you order mosquito coils at home, you must stay away from the flammable products such as mosquito nets and cotton. When using mosquito coils, you should put the lit mosquito coil on the metal bracket, and do not close the combustible materials such as mosquito nets, orders, and clothes. When people leave, they must extinguish mosquito coils.

Experiment 2:

Electric mosquito shots and various spray are enemies, and cannot be used at the same time

At the experimental site, a firefighter wearing a protective clothing was holding an electric mosquito shot to turn on the power supply, and the other firefighter sprayed an alcohol spray of a common brand to the electric mosquito. Essence Subsequently, in order to see more clearly, the experimental site simulated a closed room full of alcohol spray, replacing the room with a transparent closed box, and the bartender spray was sprayed. There was a fierce burst.

Gu Yuhan said that when the electric mosquito was turned on, the instant discharge could reach 2000 watts, which would produce small sparks. In addition, the main component in the alcohol spray is ethanol, which has strong volatility and flammableness, which is flammable and explosive, and ethanol, butane, and isoplene in the sunscreen spray also belong to flammables. Electric mosquitoes during use will produce electric sparks. It is easy to fire when encountering these dangerous combustible materials and even cause explosions.

Except for flammable spray and electric mosquito, many citizens do not know that pesticides cannot encounter bright fires during use, otherwise a large area of ​​burning will cause a large safety hazard to our personal safety. What kind of danger does pesticide encounter in the fire?

At the experimental site, while a firefighter sprayed pesticides, another firefighter opened the igniter, and a large area of ​​combustion occurred in an instant. Burning, and even the flames extended to the pesticide spray mouth along the spray.

Qu Danhuan, the instructor of the Xinyu Station of the Beilun District Fire Rescue Brigade, said that in the demonstration of firefighters, everyone can see that after spraying the spray, as long as the fire is sprayed, a large area of ​​burning will occur, or even insecticidal killing. The agent itself will become a fireproofer, which is very dangerous. In addition to the insecticide with pressure, in addition to the flammable and explosive products itself, the ingredients of insecticide are generally dissolved in organic solvents. These organic solvents are generally low -grade fat hydrocarbons, similar to liquefied gas, gasoline, kerosene, etc. substance. These low -grade fatty hydrocarbons are also flammable and explosive, and they will instantly fire when they encounter bright fires and electric sparks.

Experiment 3:

Electric mosquito coils cannot be inserted on the socket for a long time, which is easy to cause short circuit

Mosquito coils and mosquito coils are also mosquito repellent products that everyone will buy and use in recent years. Such products will not be used like mosquito coils. Relatively speaking, there will be less hidden dangers, and it will be safer to use. However, because the electric mosquito coils need to be used for plug -in, the insertion will be performed on the switch socket for a long time. Many people are inserted all night when they use electro -mosquito and flavors, and they even insert them before going to bed. In this way, sometimes it will be inserted for 7 hours or even longer. After a long time, the machine is easy to get hot. How high is the temperature of this machine? Let's measure it.

First of all, the electric mosquito coil liquid can be tested. You can see that the temperature on the industrial thermometer shows that the temperature reaches 45 degrees Celsius. This temperature is already very high. Next test the electric mosquito coil tablet, the machine temperature has reached 48 degrees Celsius. The firefighters took out the chip inside to test and the temperature reached 97 degrees Celsius under the condition of outdoor ventilation.

According to Qu Dan, through this experiment, it can be seen that if the electrical mosquito coils are in power for a long time, it is easy to cause fire. Especially after the electric mosquito flavor is heated, the temperature may reach hundreds of degrees Celsius, and the flammable materials around the flammable are burning. In the state of power, the original heat heating device and the original temperature heating film were burned and failed. When the plug was in poor contact with the socket, it was prone to fire. Nowadays, in the summer, there are more and more mosquitoes, and they can even fly into a dozen -storey and twenty -floors along the elevator, which is annoying.

Safety Tips

Ordinary mosquito

When ordering mosquito coils, be sure to put it on a metal bracket or in the metal disk, and keep a certain distance from the desk, chair, bed, mosquito nets and other combustible materials; if there is flammable liquid or combustible gas indoors, mosquito coils should not be ordered. The lit mosquito coils should be placed in places that are not easy to be encountered; it is best to check the lit mosquito coils before going to bed to ensure safety before going to sleep.

Electric mosquito flavor (liquid)

When there is dust on the electric mosquito coils, wipe it with a dry cloth or paper. If you wipe or sprinkle the liquid such as water on the electric mosquito coils with a wet cloth, it may cause a short circuit and then cause the fire. First check whether the wires, plugs, and thermist components are intact. Each time it is used, the power plug should be removed. After cooling, do the cleanup work; check whether the electric mosquito aroma is sufficient before going to bed to prevent the electric mosquito coils from burning.

Mosquito repellent spray

Consumers must recognize regular products when buying mosquito -extinguishing gas fog to prevent counterfeit and shoddy products; do not knock or squeeze the tank, do not reverse the tank, and spray it in the fire source or high -temperature burning object. Do not place near the heating object when stored, let alone heated or expose the sun in the sun; do not eat or smoke when spraying, and the spray tank should be placed in a cool place that children are not easy to get. Do not use electric mosquito shoots and pesticides at the same time, because it may cause degeneration.

Electric mosquito

When an electric mosquito shot is turned on, do not touch the mesh by hand, and the instant discharge can reach 2000 volts, while the human body's safety voltage is below 36 volts; if there are mosquito residues on the mesh, please shake the net and use it to fall off or use it. Clean the brush, do not rinse with water to prevent short circuits; you cannot use electric mosquitoes in places where flammable and explosive gas, flammable and explosive liquid, and explosive dust.
