Mosquito repellent products are really likely to cause fire!Look at this set of fire science popularization experiments →

In the summer season, many people will buy mosquito coils, mosquito repellent, electric mosquitoes, etc., but I do not know that if it is not used properly, it may also bring hidden safety hazards and even cause fires.

On August 2nd, the reporter came to the Fire Rescue Brigade of Beilun District, Ningbo City to observe a set of fire -fighting experiments.

Video production reporter Zhang Yifu intern Cen Zhihe

experiment one:

The power of mosquito coils is not small

Let's look at mosquito coils first. At the experimental site, a firefighter ignited mosquito coils, and then covered some mosquito nets to the mosquito coil plate to simulate the mosquito nets to encounter mosquito coils.

In just about 1 minute, a small amount of white smoke was raised under the mosquito net. The mosquito nets were quickly burned and black appeared in the surroundings.

Mosquito coils ignite the surface temperature

Considering the influence of the material factors of mosquito nets, the firefighters conducted the next experiment: covering the sheets on the mosquito coil plate, and simulated the mosquito coils to touch the sheets.

Nearly 5 minutes, the sheets were gradually burned, and the surroundings were black. Nearly 7 minutes, the sheets were ignited, and the fire spread rapidly. The security officer on the side quickly used the fire extinguisher to extinguish it.

Experiment 2:

Electric mosquito shoots and various flammable spray are "enemies" and cannot be used at the same time

Electric mosquito shots encounter flower dew water to make a bright fire

Look at the electric mosquito shot.

At the experimental site, a firefighter in a protective clothing was holding an electric mosquito shot with the power supply, and another firefighter sprayed a common wine spray to shoot on the electric mosquito.

Firefighters have tried sunscreen spray, flower dew, etc., and electric sparks come out.

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 sprayed with alcohol spray. Firefighters put the electric mosquito that turned on the power supply into it, and he could hear a fierce burst sound of the scene.

Electric mosquito shoots are burned violently

Next, while a firefighter sprayed insecticides, another firefighter opened the igniter and instantly burned a large area. If the spray of fire source is far from the spray of insecticides, a large area of ​​burning will still occur, and the flame even extends to the pesticide spray mouth along the spray.

Electric mosquito shot pesticides

Experiments show that flammable spray and electric mosquito can not be used together! The pesticides cannot be encountered!

Experiment 3:

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

Many people have the habit of using electric mosquito coils before going to bed, and some people will insert it all night. As soon as the time is long, the electric mosquito and aromatherapy plate is easy to get hot, so how high is the temperature? Let's measure it.

Electric mosquito coil chip surface temperature

First test the electric mosquito coils. The reporter saw that the temperature on the industrial temperature measuring instrument reached 45 ° C. Next test the electric mosquito coil tablet, the machine temperature has reached 48 ° C. The firefighters took out the chip inside to test. With outdoor ventilation, the temperature reached 97 ° C.

Qu Danhuan, the instructor of the Xinyu Station of the Beilun District Fire Rescue Brigade, told reporters that if the electrical mosquito coil tablets are in power for a long time, it will easily cause the fire; Failure, poor contact with sockets, and fires are also prone to fire.

Fire reminder:

Use mosquito repellent products to be scientifically regulated, so don't mix it blindly

Mosquito repellent is risky, and you need to be cautious. The following points of summer anti -mosquito security tips, everyone needs to keep in mind:

1. When ordering mosquito coils, be sure to put it on a metal bracket or in the metal plate, and keep a certain distance from the desk, chair, bed, mosquito nets and other combustible materials; Essence 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 that there is no safety risk before going to sleep.

2. 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; , Check whether the wires, plugs, and thermal components should be checked in each time. After each use, the power plug should be unplugged. After cooling, check the cleaning work; check whether the electric mosquito semiram is sufficient before going to bed to prevent the electric mosquito coils from burning. 3. When buying a mosquito -extinguishing gas fog, we must recognize regular products; do not knock or extrude 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.

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