How do catkins start fires?
Firefighters conducted an experiment
Restored in different scenarios
The process of "arson" of willow catkins
What happens when catkins meet an open flame?
01
What happens when catkins meet an open flame?
At the experimental site, the firefighters wore fire-fighting uniforms and protective gloves, held a ball of willow catkins in one hand and a lighter in the other hand for ignition operation. The moment it came into contact with the open flame, the catkins burned and spread rapidly, and burned out in 2 seconds.
02
How long does it take for a cigarette butt to ignite catkins?
The firefighters placed the pre-collected catkins in a cardboard box, and then threw the unburned cigarette butts onto the catkins, and the catkins that came into contact with the cigarette butts gradually turned yellow with the naked eye, and smoke came out from time to time, which immediately caused an open flame.
03
How dangerous is it for catkins to encounter a large pile of combustibles?
The firefighters found some discarded cardboard boxes, scattered the catkins on and around the cartons, and lit the catkins with a lighter, the flames spread instantly, and the fire became bigger and bigger, and the reporter clearly felt the heat wave generated by the burning one meter away, and the whole pile of cartons was swallowed by the flames and turned into ashes in less than 30 seconds.
Several experiments have shown that poplar catkins are ignited when they encounter open flames, and the fire spreads rapidly, which is very easy to cause fires with large fire areas. The on-site firefighters introduced: "Willow catkins contain a lot of oil, fluffy texture, and a large contact area with oxygen, so it is very easy to burn once it encounters an open flame. Because the rate of combustion and spread is particularly fast, if other combustibles are not found in time, the consequences will be unimaginable. ”

How to prevent catkins fires?
For gas stations, chemical enterprises, wooden processing plants, woods and grasses, garbage heaps, parking lots, kitchens and other key areas, clean frequently, and use humidification, cleaning and burial to clean up the catkins in a timely manner to avoid leaving fire hazards;
