Be careful! Insecticide second change is "flamethrower", pay attention to these safety concerns

Most families prepare toilet water, fly killer mosquito repellent incense, electric mosquito swatters, and other mosquito repellent products in the summer. Recently, the fire rescue detachment of Daxing District of Beijing reminded the public to pay attention to the safety of mosquito repellent products in summer through several groups of experiments.

A firefighter held insecticide in one hand and an electric mosquito bat in the other. He sprayed insecticide onto the electric mosquito bat. cockroach insecticide spray The open flame burst into flames.

According to firefighters, the electric mosquito bat can create an "electric spark" that can ignite flammable materials like pesticides when used to kill mosquitoes. This could lead to a fire or even an explosion. mosquito killer Therefore, it is important to avoid using the electric mosquito bat with harsh chemicals like pesticides and toilet water in areas with flammable gases, liquids, or explosive dust. If there are any remaining mosquitos on the net, shake the bat or use a brush to clean it – do not rinse with water as this may cause a short circuit. Additionally, it is crucial to never touch the mesh surface with your hands.

While conducting the experiment, the firefighters utilize candles as a source of open fire. They expose the candle flame to various substances such as toilet water and insecticide spray, resulting in a loud eruption and dangerous surge of flames. In response, one firefighter grabs a towel and coats it with toilet water before igniting it with a lighter. Almost instantly, the towel catches fire, engulfing a large area in just 8 seconds.

According to reports, most pesticides contain flammable and highly volatile solvents. The propellant in the liquid fuel tank is responsible for dispersing the "spray" of pesticides, and it mainly consists of propane and butane hydrocarbons. These substances have a low ignition point and are highly flammable and explosive. When sprayed, the pesticide liquid mixes with air, creating a potentially explosive mixture. This mixture can cause fires and explosions when exposed to open flames, as well as through friction-generated heat or electrostatic sparks. These risks are often overlooked during everyday operations.

Further, firefighters burned mosquito coils with a towel to simulate combustible material, falling on the coils. The towel turned yellow after 5 seconds, and gradually turned black, and soon burned a hole in the coil.

As soon as the mosquito repellent is lit, there is no open flame, only a small ignition point. However, this ignition point is very dangerous, since the mosquito repellent incense is primarily made up of sticky wood powder, charcoal powder and drugs. The ignition point can reach 700-800 degrees Celsius during smoldering, and it can reach 130 degrees Celsius within one centimeter of ignition.

It has been shown that both toilet water and pesticides can be flammable and explosive. People have been burned by toilet water in recent years.

In the midst of summer, there is high demand for anti-mosquito products from various companies. Firefighters advise residents to carefully select certified products and be mindful of fire safety measures when using mosquito repellents. This is especially important for children, who can dilute toilet water with water before use. After application, it is recommended to wait 5 to 10 minutes before exposing to open flames. For added safety, spraying toilet water on clothes and beds can effectively repel mosquitoes without direct contact with the skin, minimizing the risk of fire.

The spokesman said that many people close their doors and windows before spraying insecticides to achieve better pest control. As there is no ventilation in the room, it is also important to avoid open flames when using mosquito repellents such as insecticides." Pesticides should normally be stored in the dark, above 50 degrees Celsius, and away from flames under normal circumstances.
