He was reborn and became a firefighter again?

Chapter 460: Continuous Targeting

Fang Huai's throat was choked and he sat down.

The rest of the time, he was distracted while listening to the lecture.

The religious official told him that he was indeed not ready yet.

Before handing in this series of plans, he had thought about the possibility of a defense stage before a group of experts, and also thought about how to prepare theoretical knowledge.

But from the beginning of this plan, everything went so smoothly that he ignored this problem at the time.

Until this moment, the teacher said that the leader had already shown the plan to their teaching and research team.

I don’t know which leader it is, Leader Yu, Leader Chen, or someone else.

He regretted a little. The leader asked the teaching and research team whether the expert's conclusion would affect the leader's judgment.

The current plan does not even have a catalog, let alone theoretical support.

The teacher's conclusion is correct. He really hasn't studied theory very systematically. Most of the time, he just checks what he needs and combines it with his own understanding of the future. As long as he feels it is right, he will use it.

During this period, I also had some ideological changes. As my position improved, I even began to want to change the fate of the entire fire brigade, from a slightly leftist to a more radical hawkish thought. The set of things I gained from this, It will be chaotic, for sure, and there will even be some inconsistencies.

Moreover, the idea of ​​​​systematizing is to put everything in order and slowly compile it into a book from all aspects. This plan was originally intended to be done step by step. It will take more than half a year to train, so there is no time to slowly organize it.

It's really a big difference.

It’s up to you whether to pick peaches or not, but I really don’t need guidance on this matter.

Especially for such teaching and research personnel, let alone the teaching and research team, there are many people who can guide them. Before submitting their ideas, they have to fight with conservative-minded experts and waste a round of time.

Time is the most precious thing.

He must prove that he is better than those theoretical experts.

On the stage, he is still talking.

"However, Fang Huai just said it well. The three elements of fire are the key to controlling the fire.

However, he spoke in a somewhat general way.

Temperature and oxygen supply, if we control one of them, we can suppress the fire or even completely eliminate the fire.

How to control the temperature, we have already talked about it in the previous lesson.

Accurate water injection is the key to cooling down and controlling fires, and is also the prerequisite for internal attack in a violent fire scene. We should first quickly use detection methods such as circle observation and related instruments to determine the location of the fire and set up an internal attack plan.

Comrade Fang Huai, you were not in the last class. Do you know how fire investigation is divided into several parts and how to conduct fire investigation? "

Fang Huai was thinking about something when he heard the teacher call him to turn on the microphone again, and his pupils shrank slightly.

Damn, is that a bit much?

I keep asking myself, is this going to be unsolvable if I don’t let you get some light?

Fang Huai stood up helplessly again, and a probability master sitting in front of him laughed so hard that his back twitched.

Sure enough, only one will suffer, and luck will take care of most people.

Preliminary investigation of the fire, just theory, gave a whole class two days ago, it was many and complicated, it was not just Fang Huai who didn't know this? Few of those who have attended the lecture here can fully understand it!

Fang Huai gritted his teeth, trying to calm down and pay attention to his problem.

After a moment, he replied: "If I were to divide it, it should be divided into two parts: remote reconnaissance and incoming reconnaissance.

Remote detection is to determine the fire intensity and wind direction, which will affect the next step of the fire's spread. This step only needs to be felt with the eyes.

Arrival investigation is to determine the specific location of combustibles and fires. This step requires the use of all our senses. Fire can be heard, and heat can also be felt through the body.

Therefore, in this step, we must first observe the building in a circle as much as possible.

If there is a trapped person, you should first determine the signs of life, such as figures by the window, fingerprints left on the window, messy blinds, etc.

If there are no trapped persons, you must first observe the fire floor and smoke concentration, find the entry point, whether there is an opportunity to spray water from a long distance to cool down, etc., set up water distributor positions and internal attack tactics, and rely on the judgment of the fire layer and fire intensity. …”

Fang Huai kept adding to it and spoke in great detail.

To be honest, his experience in fire scenes is not lacking in his previous life. Fire extinguishing is his old skill, and he has a kind of mysterious confidence.

Therefore, in this life, he focused on emergency rescue and various disasters, and did not have much time to read about fires.

At this moment, I can only pour out what I know, just like answering liberal arts questions. If I answer more questions, I can always get the right two, right?

The students around him nodded repeatedly.

Well, that's quite right. It sounds like he often goes to fire scenes.

However, when Fang Huai had been answering for nearly a minute, the religious officer raised his hand and stopped him.

"It's still a problem, the lack of professional theory."

Fang Huai suddenly became quiet, and the students around him were also a little confused.

These things have been passed down from generation to generation of firefighters. Why are they so unprofessional?

Seeing everyone's expressions, the religious officer pushed up his glasses on the beam, smiled, and his voice became louder than the flat tone just now.

"Lack of theory is a common problem among you. Our grassroots backbones often judge problems through experience without systematic guidance. Your unsystematic thinking will lead to errors and omissions, and you will ignore some key factors.

For example, fire detection, what did we talk about in the last class? "

The religious minister turned around and wrote on the blackboard:

Visible and invisible signs.

"These are the two categories of fire investigation."

After the religious priest finished writing, he threw the chalk on the table and said with a smile:

“This is the content connected to this lesson. After the first battle force arrives on the scene, the determination of the building type starts from the pre-planning stage and becomes specific when a fire occurs.

After judging the building structure, Fang Huai was right and walked around the site to observe.

First, there's the smoke. "

The religious priest picked up the chalk again and started writing on the blackboard.

"During the field observation, the shape of the smoke partly explains what the main burning substances are. As for which burning substance corresponds to which smoke shape, it is in the book, so we will not go into details.

In addition, the direction of the smoke is also very important.

When you find that smoke is emitted from one side of the building and there is a vent on the other side, but there is no smoke, then it means that this is the air intake.

So during the field observation, we can deal with it, that is, we can close these vents. Modern buildings usually have limited ventilation, which reduces the internal oxygen inlet, which can effectively suppress combustion.

If obvious flames are found while circling the field, you can quickly draw out the gun and suppress the flame outlet to achieve the purpose of quickly controlling the fire and cooling down.

This is the efficiency that needs to be reflected in the circuit.

What should we do if there is no smoke or fire?

Then we need to use a thermal imaging instrument to judge. The extremely high thermal radiation of the fire source is enough to show the shape of any intact thermal imaging instrument. But so far, I have not seen this instrument play its correct role. You guys The subconscious judgment of this thing is that it is an instrument used only to search and rescue trapped people. "
