I'm in a mental hospital, Bai Fumei forces me to be her boyfriend

In other words, knowing the cause of a fire.

Generally speaking, firefighters have methods and experience to determine the cause of a fire.

Fire has a unique spread pattern.

Based on the debris at the scene and the direction of smoke at the fire scene after burning, the location of the fire can basically be judged.

Only when the location of the fire is found can we continue to investigate the cause of the fire in depth.

There are no more than two types.

Man-made.

Or an accident.

And the current fire...

After pondering for a while, Wang Zedao said:"When we investigated the fire scene, did we find the location of the fire?"

Liang Zhi hesitated:"The wind direction was relatively chaotic at that time."

"The origin of the fire can only be roughly determined based on the combustion conditions.

Wang Zedao:"The accuracy is not high.""

"Although in many cases the cleanest place where the fire started is the"337" area, but that is in urban areas."

"When there are many combustibles, it is difficult to judge by this. Liang Zhi nodded:"

Yes." At this time Pei Donglei said:"

Captain Wang also knows about firefighting?""

Wang Zedao:"When I was in school, I learned about some"

"Hey, it’s really hard to determine the cause of a small-scale forest fire like this."

"unlike city"

"In general urban fires, it is relatively easy to find the ignition point."

"After finding the fire point, we will use on-site combustion traces, video surveillance data, insider inquiries, on-site material composition analysis, electrical circuit detection and other means to"

"Basically, you can analyze the cause of the fire. Hearing this

, Pei Donglei was surprised:"Professional!""

Liang Zhi also looked at Wang Ze a few more times.

It's really rare for a criminal police officer to know so much about firefighting.

Wang Ze smiled and said:"Captain Pei's award, it's just a derivative of trace inspection."

"It's always good to know more."

Pei Donglei nodded.

At this moment, he suddenly understood why the other party could become the captain of criminal investigation at such a young age.

He could surpass most criminal police officers with just the theoretical knowledge he had at his fingertips.

Then, Wang Ze looked at Liang Zhi and said:"Is it possible that it’s caused by smoking?"

"What was the temperature and humidity like at the time?"

"Don't worry about whether there are outsiders, just talk about the possibilities.

Liang Zhi thought for a while and replied:"It's possible.""

"On-site temperature is high and humidity is low"

"If someone smokes, there is a possibility of causing a fire"

"But I don't remember that there was some kind of combustible property at the time that supported the inference of smoking fires."

"In general, fires caused by smoking are often confirmed through testimony from the surrounding population. Wang Ze nodded:"

That's true.""

The remaining cigarette butts can generally continue to burn for one to four minutes.

During this time, many flammable items can be ignited.

This is why fireworks are strictly prohibited in the forest.

An insignificant cigarette butt is enough to cause a fire A huge disaster.

Wang Ze continued to ask:"Yesterday, I heard from the forestry station that that forest was once inhabited."

"Where was the fire?

Liang Zhidao:"Yes.""

"In addition to the burned wooden house, there are also traces of demolition of other houses nearby, including combustible materials."

"Because the distance was not particularly close, it did not spread."

"Otherwise, the consequences will be serious."

When mentioning this matter, he was still scared.

Once a fire breaks out in the deep mountains, the consequences are immeasurable.

I'm afraid.

It will be a huge fire that cannot be extinguished for days, nights, or even months.

Wang Ze asked tentatively:" The ruins should be gone, right? (To read Baoshuang novels, go to Feilu Novel Network!)

Liang Zhidao:"It's gone a long time ago. It's been cleaned up." Wang Ze nodded:"

Okay, thank you, that's all I have to ask."

Liang Zhi smiled:"You're welcome." After saying that

, he looked at Pei Donglei.

Pei Donglei said:"Go back first. I'll call you if anything happens.""

"OK"

Liang Zhi nodded and stood up and left the office.

After Liang Zhi left, Pang Qun asked:"Do fires like this happen inexplicably outside the city happen often?

Pei Donglei said:"Not much.""

"Natural fire you said yes"

"The probability of natural fires is still relatively low"

"The reason is nothing more than spontaneous combustion caused by lightning strikes and chemical reactions."

"Captain Wang should know this, right?"

Wang Ze was thinking about something. Hearing this, he said:"I know."

"Poorly ventilated cotton, peat, coal piles, etc., as well as nitrocellulose, ferrous sulfide, yellow phosphorus, phosphine, etc., are all prone to spontaneous combustion and fire."

"In addition, some substances, such as potassium, sodium, lithium, calcium, etc., can easily catch fire when they come into contact with water."

"Cotton and straw come into contact with concentrated nitric acid, the same"

"Certain chemical products, such as potassium permanganate mixed with glycerin, can cause an immediate fire"

"There are many situations.

Pei Donglei looked at Wang Ze with admiration and said with a smile:"You're right.""

"Therefore, we must take appropriate fire prevention measures based on the characteristics of these substances"

"Don’t think that firefighting is easy, haha.

Pang Qun also smiled and said:"Listening to what you said, it's really complicated.""

After saying that, he glanced at Wang Ze and was surprised in his heart.

The other party knew too much theoretical knowledge. It was a bit beyond the scope of what he could accept.

So young.

Where did he learn it? Did he have enough time?

He couldn't have been born. Let's start learning.

At this time, Pei Donglei asked:"Captain Wang, does this matter have anything to do with the case? Is it important?

Wang Ze replied:"It's not clear yet.""

"The case is now in the comprehensive investigation stage, and any relevant incidents cannot be let go"

"Maybe related."4.5

"Maybe not relevant. Pei Donglei smiled and nodded:"

I understand, I understand.""

Although he is not a criminal policeman.

But he has never eaten pork or seen a pig running?

Check countless clues.

Maybe there is only one clue that is useful to the case.

It is normal.

And it may not really be found.

Otherwise, How can there be any unsolved cases in the world.

But after gradually getting to know Wang Ze, he suddenly felt that.

Others didn't know, but I'm afraid it would be difficult for an unsolved case to appear in the hands of this young man, right?

"So, shall we go first?"

Wang Ze looked at Pang Qun.

Pang Qun nodded and said:"Captain Pei, excuse me.

Pei Donglei:"We are all our own people, so there is no need to be polite.""
