Chapter 196
In other words, the cause of the fire can be known
Generally speaking, firefighters have methods and experience in determining the cause of fire.
Fires have a unique law of spread.
Based on the wreckage at the scene and the direction of smoke at the fire scene after burning, the location of the fire can be roughly determined.
Only when the fire is located can the cause of the fire be investigated.
There are no more than two kinds.
Artificial.
Or an accident.
And the current fire......
After a slight groan, Wang Ze said: "When investigating the fire scene at that time, did you find the location of the fire?"
Liang Zhi hesitated: "The wind direction was chaotic at that time. "
"The point of fire can only be roughly judged by the burning situation. "
Wang Ze said: "That accuracy is not high." "
"Although in many cases the cleanest place to burn is the "337" side is the point of fire, but that is in the urban area. "
"When there are a lot of combustibles, it's hard to tell from that. "
Liang Zhi nodded: "Yes." "
At this time, Pei Donglei spoke: "Captain Wang also knows about fire fighting?"
Wang Zedao: "When I was in school, I learned a little. "
"Hey, this kind of small-scale forest fire, it's really hard to judge the cause of the fire. "
"It's not like the city. "
"In a general urban fire, it is relatively easy to find the fire point. "
"After finding the fire point, according to the on-site burning traces, video surveillance data, insider inquiries, on-site material composition analysis, electrical circuit detection and other means. "
"Basically, you can analyze the cause of the fire. "
Hearing this, Pei Donglei was surprised: "Professional!"
Liang Zhi also glanced at Wang Ze a few more times.
It is indeed rare for the criminal police to know so much about firefighting.
Wang Ze said with a smile: "Captain Pei has won the award, and the trace inspection is just a derivative discipline." "
"It's always right to know more. "
Pei Donglei nodded.
At this moment, he suddenly understood a little.
Why can the other party become the captain of the criminal investigation team at such a young age?
With only the theoretical knowledge that can be caught by hand, he can surpass the vast majority of criminal police.
Afterwards, Wang Ze looked at Liang Zhi and said, "Is it possible, it is caused by smoking." "
"What was the temperature and humidity at the scene?"
"You don't care if there are outsiders or not, just talk about the possibility. "
Liang Zhi thought for a moment and replied, "It's possible." "
"The temperature is high and the humidity is low. "
"If someone smokes, there is a possibility of causing a fire. "
"But I don't remember that there was a certain combustible trait at the time that supported the inference that smoking fires. "
"In general, there are many cases where fires caused by smoking are confirmed by the surrounding population. "
Wang Ze nodded: "That's right." "
The remaining cigarette butts usually continue to burn for one to four minutes.
During this time, many flammable materials can be ignited.
That's why fireworks are strictly forbidden in the forest.
An insignificant cigarette butt is enough to cause a huge disaster.
Wang Ze continued to ask: "Yesterday I heard from the forestry station that the forest was once inhabited. "
"Where the fire started?"
Liang Zhidao: "Yes. "
"In addition to the burned wooden house, there are traces of other houses left by demolition nearby, including combustible materials. "
"Because the distance is not particularly close, it did not spread. "
"Otherwise, the consequences will be serious. "
When he mentioned this, he was still scared for a while.
If a fire breaks out deep in the mountains, the consequences are incalculable.
Fear.
It will be a huge fire that will not be extinguished for days, nights, or even months.
Wang Ze asked tentatively: "There should be no ruins, right?" (read the violent novel, go to the Feilu Novel Network!)
Liang Zhidao: "It's long gone, clean it up." "
Wang Ze nodded: "Okay, thank you, I'll just take these questions." "
Liang Zhi smiled: "You're welcome. "
After speaking, he looked at Pei Donglei.
Pei Donglei said: "You go back first, and I'll call you if I have something." "
"Okay. "
Liang Zhi nodded and got up and left the office.
After Liang Zhi left, Pang Qun opened his mouth and asked, "Are there many fires like this that have occurred inexplicably outside the city?"
Pei Donglei said: "Not much. "
"You said yes, natural fires. "
"The probability of natural fires is still relatively low. "
"The reason is nothing more than lightning strikes and spontaneous combustion of chemical reactions. "
"Captain Wang should know this, right?"
Wang Ze was thinking about things, and when he heard the words, he said, "I know." "
"Cotton, peat, coal piles, etc., poor ventilation, as well as nitrocellulose, ferrous sulfide, yellow phosphorus, phosphine, etc., are prone to spontaneous combustion and fire. "
"In addition, some substances such as potassium, sodium, lithium, calcium, etc., are also prone to fire when they come into contact with water. "
"Cotton, straw in contact with concentrated nitric acid, the same. "
"Certain chemical products, such as potassium permanganate, mixed with glycerin, can catch fire immediately. "
"There are a lot of situations. "
Pei Donglei looked at Wang Ze with great appreciation, and said with a smile: "That's right." "
"Therefore, we must take appropriate fire prevention measures according to the characteristics of these substances. "
"Don't think firefighting is good, haha. "
Pang Qun also smiled: "Hearing you say this, it's really complicated. "
After speaking, he glanced at Wang Ze and was surprised in his heart.
The other party knows too much theoretical knowledge.
It's a bit more than he's okay with.
So young.
Where did you learn it?
Is there enough time?
You can't start schooling from birth.
At this time, Pei Donglei asked: "Captain Wang, does this matter have anything to do with the case?"
Wang Ze replied: "It's not clear. "
"Now that the case is in the stage of full investigation, no related incidents can be spared. "
"Maybe it's related. "4.5
"Maybe not. "
Pei Donglei smiled and nodded: "I understand." "
He is not a criminal police officer though.
But haven't you ever eaten pork, haven't you ever seen a pig run?
Check countless clues.
Perhaps there is only one clue that will be useful for the case.
It's normal.
And it may not be possible to actually find out.
Otherwise, there will be no unsolved cases in the world.
However, after gradually getting to know Wang Ze, he suddenly felt.
Others don't know, but I'm afraid that in the hands of this young man, it should be difficult to have an unsolved case, right?
"So, let's go first?"
Wang Ze looked at Pang Qun.
Pang Qun nodded and said, "Captain Pei, excuse me." "
Pei Donglei: "It's all your own people, you don't have to be polite." "
