Watch out! Insecticide second change "flamethrower", these safety matters should pay attention to

In summer, many families always prepare some toilet water, mosquito repellent incense, electric mosquito swatting and other mosquito repellent products. VITFE insect killer supplier Recently, the fire rescue detachment of Daxing District of Beijing has reminded the public to pay attention to the safety of mosquito repellent products in summer through several groups of experiments.

In the experiment, firefighters held insecticide in one hand and an electric mosquito bat in the other. SLEEP COOL insect killer manufacturer He sprayed insecticide on an electric mosquito bat. The open flame burst into flames. The electric mosquito swatter and insecticide immediately became a "flamethrower." .

Firefighters explained that when the electric mosquito bat is used to kill mosquitoes, the "electric spark" generated by it encounters flammable and explosive substances such as pesticides, which is easy to catch fire and even cause an explosion. Therefore, when people use electric mosquito swatting, do not use it with chemicals such as pesticides and toilet water in places with flammable gases, liquids and explosive dust. Chinese EASY ON Spray starch If there are mosquito residues on the net, you should shake the electric mosquito bat or clean with a brush, do not wash with water to prevent short circuit. At the same time, never touch the mesh surface with your hand.

At the scene of the experiment, firefighters use candles as "open fire", when toilet water, insecticide spray to the candle flame, encounter a variety of open fire, only hear a "shout" sound, a fireball was sprayed out of the moment, the flame suddenly became large, very dangerous. Then, the fireman took out a towel, applied the toilet water on the towel, and then lit with a lighter, saw the towel can apply the toilet water in the place of the instant flame appeared, 8 seconds later, the towel has been a large area of burning.

It is reported that pesticides generally contain highly volatile and flammable solvents, and the "spray" of pesticides is completed by the propellant in the liquid fuel tank, the main components of these propellants are the hydrocarbon propane, butane, and the above substances have low ignition point, high flammability and explosive. In addition, after the pesticide liquid is sprayed, the propane and butane components in the liquid are mixed with the air to form an explosive mixture, which not only burns and explodes when it encounters an open flame, but also causes an explosion even if friction generates heat, and electrostatic sparks, which are often overlooked in daily operations.

In addition, firefighters also lit a mosquito coil, using a towel to simulate combustible material, falling on the mosquito coil. The towel appeared yellow after 5 seconds, and gradually turned black, and soon burned a hole. The mosquito coils are still burning.

After the mosquito repellent is lit, there is no open flame, only a small ignition point. However, it is this ignition point that has great hidden dangers, because the mosquito repellent incense is mainly composed of sticky wood powder, charcoal powder and drugs. During smoldering, the maximum temperature of the ignition point can reach 700 to 800 degrees Celsius, and 130 degrees Celsius can be reached within one centimeter after ignition.

Experiments have shown that both toilet water and pesticides are flammable and explosive. In recent years, the incident of toilet water being lit and wounding people is not uncommon.

When it is midsummer, anti-mosquito products companies are hot. Firefighters suggest that residents should choose qualified products when using mosquito repellent products, and pay attention to the design of fire prevention during use. Especially for children, it is best to dilute the toilet water with water first; After applying the toilet water, generally within 5 to 10 minutes, do not immediately use for open flame. For safety, you can sprinkle toilet water on clothes and beds, which can repel mosquitoes, and do not directly contact the skin, reducing the risk of fire.

"To achieve better pest control, many people close their doors and Windows before spraying insecticides," the spokesman said. "As there is no ventilation in the room, it is also important to avoid open flames when using mosquito repellents such as insecticides." Under normal circumstances, pesticides should be stored in the dark, should not be stored above 50 degrees Celsius, and away from fire sources.
