The fire department recommends the use of fire doors in the kitchen and master bedroom of the home. When a fire breaks out and it is too late to escape, a fire-proof door will give the trapped people valuable waiting time for rescue.
Yesterday, the fire brigade conducted a set of comparative experiments to show everyone the importance of fire doors.
The experiment was conducted in an abandoned building. The two rooms on the site were arranged to look like rental houses, one of which was an ordinary wooden door and the other was a qualified wooden fire door.
The experimenter first lit the trash can in the room. After the trash can burst into flames, the doors and windows were closed tightly. It can be seen from the surveillance video that the fire in the two rooms spread rapidly, igniting nearby sofas, tables, chairs and other items. Then, heavy smoke accumulates on the ceiling.
After burning for about 4 minutes, you can see from the outside that there is continuous thick smoke coming out of the ordinary wooden door, but no smoke can be seen on the side of the fire door. After continuing to burn for 10 minutes, the ordinary wooden door was burned through, and a large amount of black smoke gushed out.
Subsequently, the experimenters put out the fire. Comparing the back of the two doors, the ordinary wooden door has been charred, and the lump will fall off when it is touched hard. The fire door just looked a little black, with a thin layer of soot on the surface, and the door was still intact after erasing it.
Fire doors are the line of protection for people's lives. "In addition to the function of ordinary doors, fire doors also have the effect of preventing the spread of fire and smoke. If there is a fire and cannot escape, the trapped persons can hide in rooms equipped with fire doors and wait for fire rescue. .
In addition, the kitchen and the master bedroom are two places with a high probability of fire, so he suggested that every household can replace these two doors with fire doors. "But there is one more thing to be aware of. Inferior fire doors can not only prevent fire when a fire occurs, but can also expand the fire.
