As the saying goes: fire and water are merciless. Water can carry a boat, but it can also capsize a boat. It's the same with fire.
In ancient times, our ancestors relied on fire for cooked food, fire for heating and lighting, and to some extent, it can be said that fire was the catalyst for human evolution and upgrading.
The premise is that it must be controllable, otherwise, it will "turn its face and deny people".
There was a story about a small town in the United States where fire accidents often occur. At first, the firefighters went everywhere to fight the fire, and they were so busy that they only felt that there were not enough people. However, the increase in personnel should be much better, but the result is still not much less.
What the hell is going on? At this point, reflective abilities come into play.
Since this road is impassable, let's change the way of thinking: there must be conditions for the occurrence of fire, one is combustibles, the other is oxygen, and there is a necessary condition: temperature, any combustion will only occur if the temperature reaches its ignition point.
Then start from "destroying" the burning conditions, like the Queen Mother will be the Cowherd and the Weaver Girl, build a galaxy in the middle, so that the two will never see each other, and there will be no "spark of love".
For fires, isolation can also be used. That is, from the thinking of fire extinguishing to prevention, as a result, the number of fires has decreased significantly, major fire accidents are almost zero, and as for the spark, it has also been nipped in the bud during the usual inspection.
How to "destroy" its "meeting conditions"?
Clause. 1. Let it be hypoxic. It is impossible to kill all the air, let alone it, we don't turn on oxygen for a second. It seems that it is not feasible to deal with the tung chai accelerant, i.e. air.
Clause. 2. Control combustibles. Keeping combustibles away from our lives and returning to the primitive state of drinking blood: covering shame with leaves? It's impossible and it's too extreme. As long as the flammable materials are kept away from the fire source, that is, the fire source is isolated, it is also controllable and effective.
Clause. 3. Control the temperature.
The mechanism of combustion occurs only when the combustible material reaches its ignition point, not only open flames. Of course, in an environment where flammable materials are present, it is still very necessary to strictly prohibit fireworks and smoke.
The legendary "ghost fire" is the combustion of phosphorus, and the ignition point of phosphorus is about 40 degrees Celsius, and the ignition point is low, which is spontaneous combustion. This phenomenon generally occurs in the hot summer.
Whether it is spontaneous combustion or "other combustion", the key is to control the temperature below its ignition point.
In life and work, I often hear that whoever is a firefighter is a person who can solve major problems, and once the problem is solved, the propaganda and reports are overwhelming, this is the hero.
In normal times, the "firefighters" who insist on conducting fire inspections regularly and irregularly are nameless.
In the same way, we only remember the heroes of the flood fight, but ignore those who usually block the anthill, and at this time, they often throw the "embankment of a thousand miles in the anthill" behind.
Unsung heroes are more worthy of respect.
Fire prevention is better than fire fighting!

Fire brings us a lot of convenience, but it also brings us danger, and if a fire breaks out carelessly, it will cause loss and harm to our property and life. Learn to use the fire. So how do you prevent fires from happening?
Fire prevention measures for TV: When the indoor temperature is too high, turn on the TV for 7-8 hours in a row and turn off the TV to rest for a while, in order to dissipate heat, remove the TV cover when watching TV. Prevent lightning strikes and do not turn on the TV during thunderstorms.
Fire prevention measures for electric mattresses When the electric mattress is used, do not fold it, so as not to damage the insulation part of the wire, causing a short circuit and causing a disaster. When not in use, be sure to cut off the power and include the old stool to avoid overheating and fire at high temperatures.
Fire prevention measures for electric irons.
When the temperature of the iron is too high, the temperature can ignite flammable items. So cut off the power supply when the iron is not in use.
Refrigerator fire prevention measures.
When the temperature of the refrigerator radiator is very high, please do not put flammable materials behind the refrigerator Please do not use the refrigerator to store flammable liquids such as ethanol, because sparks are generated when the refrigerator is started.
Do not wash the refrigerator with water to avoid a short circuit.
The switches and sockets of the lamps are always checked for insulation damage.
When the current of the incandescent lamp passes, it can produce a high temperature of 2000-3000 degrees, because the bulb is filled with inert gas to conduct heat, so the temperature of the glass surface is also very high, and no combustibles should be placed under the bulb.
The surface temperature of the cigarette butt that has just been discarded is between 200-300 degrees, and the temperature in the center can reach about 700-800 degrees.
