They were all reborn and became firefighters again?

Chapter 171: Living in this world, one must listen to advice
When we left the cafeteria, there was a big group.

The car left the squadron, but only one car and four or five people got in.

Only one of the new recruits went to Fang Huai, but this time, the Chief Secretary, who had always been reclusive, was actually summoned by Cao Yi.

When getting on the bus, Cao Yi told everyone about the police situation.

Fatal accident, three people died, a proper police officer.

High-voltage power lines touched the ground and the incident occurred on the side of a sidewalk.

The chief of staff used to be an electrician, so he was specially called by Cao Yi.

When Fang Huai heard this, he felt some nosebleeds in his heart. He did not hesitate to exchange 1 point of military merit for a piece of high-voltage electricity safety knowledge.

Once knowledge enters the brain, the nervous heart begins to calm down.

Fang Huai was touched by electricity once in his previous life. The palpitations and uncomfortable feeling all over his body made him afraid of electricity for many years.

Moreover, high-voltage wires are extremely dangerous in the eyes of Fang Huai, who used to watch short videos in his previous life.

Anyone who has ever died knows that once a high-voltage line is touched, there is no chance of escape.

There used to be a widely circulated joke:
A man's shoe got gravel in it. He took off his shoe while holding on to a telephone pole and started shaking. People behind him thought he was getting an electric shock and went up to him and broke his hand.

This thing is somewhat misleading.

The three wires on the telephone pole are all high-voltage electricity.

If someone really touches a telephone pole and gets an electric shock, there must be a cause of conduction. You must see clearly before helping.

[-]. Is it a rainy day?

[-]. Did the high-voltage wire fall to the ground and cause an electric shock?

In both cases, the rescuer will be electrocuted.

The first one is only possible, while the second one is inevitable.

Just as Fang Huai was thinking about it, Cao Yi had already started asking:
"Chief Secretary, in this case, how many meters away should we set up a warning?"

The chief of staff thought for a while and said: "20 meters is okay. It's sunny today. Anyone without electrical insulation clothing must not get close."

Fang Huai answered: "Instructor, it is best to be 30 meters. The specific situation depends on the height of the wire. If it is a 6-meter pole, it is best to wear insulating clothing and stay away from it."

Cao Yi turned around in surprise: "Do you understand this?"

Fang Huai nodded.

At this time, not expressing a clear attitude will only make people doubt their own judgment.

After sorting out his thoughts, Fang Huailanglang said:

“Except for telephone lines, the national standard for wire heights is based on the voltage of high-voltage lines.

The 4-meter one has a voltage of less than 1000 volts, and the 6-meter one has a voltage between kilovolts and ten thousand volts. Our electrical insulation clothing has a maximum voltage resistance of 5000 volts. If it exceeds this voltage, it will be broken down.

Moreover, a high-voltage line touching the ground will radiate voltage to the surrounding ground, creating a high-voltage field with the grounding point as the center.

This electric field will gradually reduce the voltage from the center of the circle to the outside.

Once it is found that the high-voltage line is grounded, it cannot be moved arbitrarily. Once a person's two feet are stepped apart, a voltage difference will be formed between the two feet at the moment of landing.

Commonly known as step voltage.

At that time, the human body becomes a path from high voltage to low voltage, forming an electric current.

The larger the step, the greater the voltage difference and the greater the current.

If the voltage of 20 volts in the center spreads out in a radius of [-] meters, think about it, what is the voltage difference in one step?
If it exceeds 30 volts, the human body will clearly feel the current. If it exceeds 36 volts, it exceeds the safe voltage. If it exceeds [-] volts, it will be impossible to escape.

Therefore, the longer you run, the faster you die.

Once you enter this electric field, you must not run. The safest way is to jump away with one foot. If one foot is on the ground, your body will not be able to create a voltage difference. If you have poor balance, you can only move your feet together as slowly as possible. .

Also, the human body does not have much resistance at all. If it comes into direct contact with a charged person, it is not much different from touching a wire.

If the current exceeds 50 milliamps, it only takes one second to cause death.

Moreover, electric shock may cause chronic atrial fibrillation in the heart. It may be fine at the time, but after an hour or two, the heart will begin to malfunction, leading to death.

No matter how strong our bodies are, we are all very vulnerable to electricity. We still have to keep an absolute safe distance from this kind of thing.

By the way, Director Cao, has the power supply bureau received the news?The power needs to be cut off. "

There was a brief silence in the car.

Everyone was immersed in Fang Huai's "eruditeness" and what he just explained.

Cao Yi slowly replied: "The 119 command center has already notified the police. The person who called the police was very smart. He didn't know the phone number of the power supply bureau and called 119 first.

But they may be slower to arrive. The command center called and asked us to evacuate first. "

Fang Huai then said: "The car is parked 50 meters away. There are only two sets of electrical insulation suits on the car. Squad leader Xiaohei and I will go in with the insulation hooks and warning devices to deal with it."

But the chief of staff said: "Don't go, Xiao Hei. I'll go. I've worked in electricity, so I'm familiar with it."

Fang Huai smiled and said: "Chief Secretary, you are a veteran and you are still in a logistics position. In your last year, you can still rest peacefully.

Veterans are most likely to get into trouble when they go to the police. If you go, I feel unsafe following you. "

"Hahaha…"

There was a fatal accident at the scene, and everyone felt a little bit sad in their hearts, but when Fang Huai interrupted, they all laughed.

……

After putting on insulating clothing and entering the scene with equipment, Fang Huai finally understood why the caller was so sure it was a fatal accident.

There was a large truck that was in an inverted bucket state at the scene. The wires were caught in a truck bucket and one was pulled off.There were two men near the truck very close to where the power line fell. Judging from the open doors on both sides and their clothes, they were both in the truck. They jumped out of the truck and were electrocuted.

Another woman on the roadside was also motionless. She was still holding vegetables in her hand, and the onions in the bag rolled to the side.

There were probably others who were electrocuted, but they were probably far away and they were all rescued.

Probably no one would dare to touch these three people.

The clothes of the three people were burnt and in pieces, and their calves and thighs were also burnt black.

The body must have been on fire. Some of the exposed parts have been penetrated, but they have dried up. The dryness has increased the resistance of the body, and there are no combustibles around, so it has not caught fire again.

In this case, the internal organs are already mushy.

The scene was silent. On the other side of the street, there was a traffic policeman directing them. When they saw them entering the electric field, they immediately crossed their hands significantly and made a stop gesture to them, indicating that they should not get closer.

Someone must have tried to get closer and suffered a loss.

When Fang Huai saw the situation, he immediately waved his hand towards Xiao Hei.

Hopeless.

The body is burnt on the outside and tender on the inside. Pulling people with an insulated hook will only destroy their body.

There are traffic police on the other side, and the people on the left and right sides have also evacuated. Please retreat.

Damn it, just tell the truck not to drive into town blindly.

Even if the line is broken, don't jump out of the car. At least it's safe inside, a natural Faraday cage.

This time, it was better. He had harmed the woman passing by, and he himself was also dead.

The hope of three families.

In this case, the insurance company will not pay compensation. If this car has an owner, it will be a big deal this time.

Not to mention people, if the high-voltage power is cut off once, the compensation will be sky-high.

Fang Huai and Xiao Hei shouted around the area, looked around ten meters away along the street, and made sure there was no one there before exiting the high-voltage electric field and setting up a warning at the parking area of ​​the fire truck.

Cao Yi, the chief of staff, and Jiang Jun from the emergency team stopped pedestrians and cars on both sides and in the middle of the road, and were explaining to them loudly.

But many people stopped there, leaning on their feet to look over there. Some people took out various photography tools and wanted to take pictures, but they were all stopped.

Fang Huai pulled off the hood of his electrical insulation suit, approached Cao Yi and said:
"There's no one inside. Those three can't be saved. When the power goes out and 110 comes to take over, let's evacuate."

Cao Yi looked back at Fang Huai, who had a sullen expression on his face. He pulled Fang Huai aside and pointed to the police lane parked on the roadside not far away:

"110 has arrived. Discuss with us and let us dispose of the body.

Why, the scene was so scary that it scared you? "

Fang Huai shook his head and said nothing.

Just thinking about the miserable situation of the three people made me want to smoke a cigarette.

This was the first police call since his rebirth that he couldn't save, and he didn't even dare to touch it.

All I can say is that when people live in this world, they have to listen to advice.

After a while, a yellow pickup truck from the Power Supply Bureau arrived, and two electricians put on their equipment and entered.

After a while, someone came out and informed them that the power had been cut off and repairs were being carried out. He asked them to go in and call some people and get the bodies out first, otherwise the work would be difficult.

Cao Yi greeted: "Sun Jingwu, you get out of the car and take charge of security. We can go in and dispose of the body!"

In this case, the scene still needs to be sealed until the body is disposed of. It is up to the police how they take over.

Fang Huai had no idea what was in the car. Fang Huai took a few pieces of paper and cloth used by the squadron to store quilts under the equipment area at the back of the car, and followed Cao Yi inside.

Many of these useless cloths were collected in the car just for this situation.

Before the family members arrive, the deceased must be covered with a cloth to prevent the family members from losing control of their emotions.

Several people arrived at the scene, all feeling a little uncomfortable to varying degrees.

The parts burned by the electric shock were different for the three people.

Women are slightly better, mostly on the body and neck, and the face is a bit dark, but still relatively complete.

Of the two men who were relatively close to each other, one had half of his face burned, the other had his whole body scorched, and there was a big dry hole on the outside of his right calf, and the blood had long solidified.

Being so close, there was still a burning smell, like some burned rubber, a bit sour.

Maybe shoes.

Several people wore gloves and carefully lifted the three people to the roadside.

Some injured areas cannot be dragged hard. No one knows the extent of the electric shock. Anyway, the skin is easily broken after being burned to death in the fire.

When lifting the man with a burnt face, his neck was loose for a moment, as if his head was about to fall off. Jiang Jun, who was lifting him up, was startled. He wanted to curse, but he still held back.

The three people were quickly lined up in a row.

Fang Huai untied the tied oil paper cloth, took out three pieces, and covered them one by one.

110 and 120 arrived soon.

120 got out of the car, opened the paper, checked it symbolically, shook his head, and left.

I got off the bus at 110 and shook hands with Cao Yi.

"Excuse me, we have a lesbian here this time...she is afraid." The two young male policemen smiled and looked at the car on the road.

Fang Huai was speechless.

Is she afraid?Are you not afraid?
I'm so scared!
