Because there are many tiny particles in the flour, if the flour is completely held in the air and touches the fire, the small particles in the flour will burn and release energy, so a large area of flour together will definitely explode due to the fire. But this kind of explosion is not that kind of impact, but the shock wave produced by the accumulation of energy combustion. But don't worry, the flour at home is not big enough at first, so it is impossible to lift all the flour into the air and light it again.
However, one of the biggest hazards of flour at home exists objectively, that is to say, if a handful of flour is sprinkled on the gas stove when it is burning, it will definitely turn into a small-scale fire, even if it does not cause a fire at home, it will do us some harm. In this way, we should be cautious about this matter, especially for the elderly at home, and we should always remind them of these things to prevent problems.
As old people get older, they will be slower to respond to many things. Because my hometown is in the countryside, once when my mother was using a gas tank, natural gas came out directly because the hardware valve of the gas tank was broken. If it weren't for me, it would be very dangerous, because my mother was in a mess. I resolutely picked up the gas tank, took it to the yard, and then closed the main valve to prevent danger.
