In spring, cities with willows will be covered with snowflakes, and catkins can cause skin allergy. The latest news even says that catkins can detonate cars. Is that true?
A few days ago, a fire broke out in a parking lot in Chaoyang District of Beijing, causing 90 motor vehicles to catch fire. After firefighters put out the fire, preliminary investigation found that the cause of the fire was the rapid burning of poplar catkins, which ignited the parking lot. Further reasons are still under investigation.
Is willow catkins really inflammable? How fast is the fire spreading? This morning, Daxing fire brigade used willow catkins to do a test of igniting a car. Willow catkins quickly burned in 2 seconds when encountering an open fire, and ignited the car in about 1 minute.
Daxing fire brigade used Yang LiuXu to conduct a test of igniting a car in an automobile disintegration plant at 10 am this morning.
The reporter saw that in the field test, the fire officers and soldiers used lighters to ignite the willow catkins under the bottom of an abandoned car. The willow catkins burned rapidly within 2 seconds after encountering an open fire. In addition, today's wind is relatively strong. With the burning of willow catkins, the fire spread rapidly, igniting the car in about one minute.
Less than 2 minutes after burning, the car gave out a bang, and the fire became even bigger. According to the fire officers and soldiers on the scene, the loud noise was caused by a tire burst caused by the fire.
The firemen on the scene used fire extinguishers to put out the open fire, but there was still open fire burning under the car. The firemen then used water guns to put out the fire. It took several minutes to put out the open fire under the car completely, but the ignition time was only a few seconds.
Analysis of the flammability of willow catkins falling everywhere is not easy to control
Wang Jian, director of Huangcun squadron of Daxing fire brigade, said: 'catkins are flammable substances. Experiments show that catkins can burn rapidly in 2 seconds when they meet open fire. Some children playing with fire and adults throwing cigarette butts will lead to the ignition of willow catkins and become the fuse of fire. '
Wang Jian, Yang catkins fire spread fast. Because of its falling everywhere, everywhere, whether it is the edge of the haystack, around the houses, or in the ditch, on the shed, if it is not controlled in time, it is very easy to form a large fire.
Yangliuxu fires mostly occur in rural areas. Due to the poor traffic conditions, large fire engines of fire squadron can not enter, and sometimes they even need to carry equipment on foot, which increases the difficulty of fire fighting.
