High fire temperature or spontaneous combustion of wood
Naga city fire chief Hiroshi shimako said frankly that once the painted building catches fire, it will be more difficult to put out the fire than ordinary buildings.
At the same time, due to the extremely high temperature of the fire site, even the wood far away from the fire head will be ignited naturally due to the high temperature, and the firefighters cant be too close to the fire site to avoid being hurt by the high temperature, making the fire more difficult to control.
The authorities also announced that when the main hall of the capital city was on fire, the iron gate or was locked. After the guards arrived at the scene to unlock the lock, the hall was full of smoke. Moreover, because the fire-proof induction device of the main hall used the slow response air pipe technology, and there was no automatic sprinkler, the fire could not be controlled before the fire.
