[Fire experiment] "Drease doesn't wet" to protect your baby

If there is a misfortune at home, what other items can protect the baby from the fire when it is rushed out of the fire? On September 19th , the fire brigade of the Weiwu Road Squadron in the brigade of the Lianyungang City Fire Fighting Brigade made a series of experiments to see which items in residents’ homes could temporarily become “protective equipment” in the event of a fire. Unexpectedly, infants' urine is not wet and can play a protective role in the fire after soaking in water.

At the scene of the experiment, firefighters brought towels, thick clothes, aluminum foil, and non-wet diapers. They then placed them on four plush toy rabbits to imitate the fire. The baby used these items for protection.

“We use soft toy rabbits instead of babies. Before we start the experiment, we first soaked towels and other props with water, and then put them on stuffed rabbits.” Firefighters introduced that they use firearms to simulate the fire scene. Open fire, the main component of this type of gun is butane, and the temperature is about 800 °C . Unless it is a chemical or a special fire caused by fuel, the fire in the home usually occurs. The central temperature of the fire is between 800 °C and 1000 °C .

The fire experimenter lit a fire against a plush rabbit wearing a towel. The flame quickly evaporated and the towel dried instantly. After burning for about 20 seconds, the towel was burned.

“The towel in the house is generally cotton. Once it is dried, the burning speed is very fast, and it burns immediately,” he said. Although the towels are wet, the moisture evaporates quickly under high temperatures, so the fireproof effect is not good.

Subsequently, the fire experimenters conducted experiments on thick clothes. Firefighters used spray guns on thick clothes that were filled with water. However, 20 seconds later, the experimental staff found that its material is also very easy to catch fire. As soon as it is baked, there is a fire coming out. This water has almost no effect, and the whole area of ​​the flame is burning up. It is very easy. Burned through.

What about aluminum foil? The firefighters turned the ignited spray gun on and the aluminum foil became red. In a matter of seconds, the aluminum foil burned.

The experimental personnel introduced that aluminum foil is suitable for grilling because it has thermal insulation and heat conduction. In the face of the 800 °C flame, it will only rapidly heat the burned skin, so it must not be used for fire protection.

Finally, the firefighters wrapped diapers filled with water in a plush toy rabbit. The spray guns burned for more than 30 seconds and only heard the sound of water evaporation, but the flames could not be burned. .

Why doesn't the humble urine not play a certain role in fire protection? Liu Longfei said, “Because the filler in the urine is mainly a kind of highly water-absorptive resin, a piece of urine can absorb more than 700 milliliters of water. And the gel after water absorption is very strong, and it is hard to squeeze. No water comes out, so in the fire scene, the use of wet urine wrapped around the baby can provide some protection, similar to the daily fire protection of people with wet quilts."
