When I came out of the cafeteria, there was a big bunch.

The car went out of the squadron, but only one car, four or five people.

The recruits only went to Fang Huai, but this time, the secretary general, who had always lived in seclusion, was actually called by Cao Yi.

When getting into the car, Cao Yi told everyone about the police situation.

Fatal accidents, three deaths, proper police.

The high-voltage power line touched the ground and the incident occurred on the side of a sidewalk.

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

When Fang Huai heard this, he also had a nosebleed in his heart, and he did not hesitate to exchange 1 point of military merit for a high-voltage safety common sense.

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

Fang Huai had been touched by electricity once in his previous life, and that kind of palpitations and uncomfortable feeling all over his body made him afraid of electricity for many years.

And the high-voltage line is 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 the high-voltage line is touched, there is no chance of detachment.

There used to be a widely circulated joke:

A man got his shoe into a stone, took off his shoes on a telephone pole and began to shake, and the people behind thought he was electrocuted, so they went up and broke his hand.

This thing is somewhat misleading.

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

If someone really touches a telephone pole and is electrocuted, there must be a conductive cause, so we must see it clearly and then rescue.

1. Is it a rainy day?

Second, whether the high-voltage wire fell to the ground and caused the electric shock.

In both cases, the rescuer will be electrocuted together.

The first is only possible, and the second is inevitable.

Fang Huai was thinking about it, and Cao Yi had already begun to ask:

"Secretary, in this case, how many meters away should we set up a cordon?"

The secretary thought for a while and said, "20 meters, it's okay, it's sunny today, and those who are not wearing electrical insulating clothing must not approach." ”

Fang Huai answered: "Instructor, it is best to be 30 meters, the specific situation, it also depends on the height of the wire, if it is a 6-meter telephone pole, it is best not to approach it in insulated clothing." ”

Cao Yi looked back in surprise: "You know this?" ”

Fang Huai nodded.

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

After sorting out his thoughts, Fang Huai Langlang said:

"In addition to telephone lines, the height of wires set by the state is based on the voltage of high-voltage lines.

4 meters is below 1000 volts, 6 meters, is the voltage between 10000 volts and 10,000 volts, our electrical insulating clothing can withstand up to 5000 volts, and if it exceeds this voltage, it will be broken down.

In addition, the high-voltage line that touches the ground will emit voltage to the surrounding ground, generating a high-voltage field centered on the contact point.

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

Once it is found that the high-voltage line is grounded and cannot be moved, once the two feet of the person step across, the voltage difference between the two feet will be formed at the moment of landing.

Commonly known as step voltage.

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

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

If the voltage in the center of 10,000 volts is spread in a radius of 20 meters, do you think, what would be the voltage difference in one step?

If it exceeds 30 volts, the human body will clearly feel the current, and 36 volts will exceed the safe voltage, and hundreds of volts will not be able to get out.

So, the bigger you run, the faster you die.

The safest way is to jump away with one foot, and if you land on the ground with one foot, your body will not be able to form a voltage difference, and if your balance is not good, you can only move slowly with both feet together as much as possible.

Also, the human body doesn't have much resistance at all, and if you directly touch a charged person, it's not much different from touching a wire.

If the current passes through more than 50 milliamps, it only takes one second and can be fatal.

And electric shock may cause brady-atrial fibrillation, which may be fine at the time, but after an hour or two, the heart begins to malfunction, leading to death.

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

By the way, Director Cao, did you receive the news from the power supply bureau? I have to cut off the power. ”

There was a brief silence in the car.

Everyone was immersed in Fang Huai's "erudition" and the content just explained.

Cao Yi replied slowly: "The 119 command center has been notified, and the person who called the police is also very smart, I don't know the phone number of the power supply bureau, so I called 119 first."

However, they may be slower to come, and the command center called and told us to evacuate first. ”

Fang Huai said: "The car is parked 50 meters away, there are only two sets of electrical insulating clothing on the car, and the little black squad leader and I will take the insulating hook and the warning device to enter the processing." ”

The secretary said: "Xiao Hei don't go, I'll go, I've done electricity, get familiar with it." ”

Fang Huai said with a smile: "Secretary, you are a veteran, or a logistics post, in the last year, you can rest in peace."

Veterans go to the police, and they are most likely to have accidents, and if you go, I feel that it is not safe to follow you. ”

"Hahaha..."

The fatal accident at the scene was somewhat shadowy in everyone's hearts, but Fang Huai laughed when he interrupted like this.

……

Wearing insulating clothing and entering the scene with equipment, Fang Huai finally knew why the caller was so sure that it was a fatal accident.

There was a large truck at the scene that was in an upside-down state, and the wires were caught by a truck bucket, and one was pulled off.

There were two men near the truck who were very close to the place where the wires landed, and judging by the open doors on both sides and the clothes they were wearing, both of them were on the truck, jumped out of the car and were electrocuted.

Another woman on the side of the road was also motionless, still carrying vegetables in her hand, and the onions in the bag rolled to the side.

Others should have been electrocuted, but they may have been far away, and they were all rescued.

These three people, probably no one dares to touch them.

The clothes of the three were charred and very fragmented, and their calves and thighs were also charred on the outside.

The body should have been on fire, some of the exposed parts have been penetrated, but they have dried up, and the current drying has increased the resistance of the body, and there is no combustible material around, so it is not on fire again.

In this case, the internal organs are already paste.

The scene was silent, and on the other side of the street, there was a traffic police officer directing, and when he saw them enter the electric field, he immediately crossed his hands sharply and made a stop gesture to them, signaling them not to approach any longer.

Someone should have tried to get close and suffered a loss.

Seeing the situation, Fang Huai immediately waved his hand at Xiao Heiye.

There is no help.

The body is scorched on the outside and tender on the inside, and pulling people with an insulating hook will only destroy their body.

There is a traffic police on the other side, and the people on the left and right sides have also withdrawn, so retreat.

Damn, let's just say trucks don't go into town blindly.

If you break the line, don't jump out of the car, at least it's safe inside, a natural Faraday cage.

It's okay now, I hurt the women who passed by, and I was gone.

Hope for three families.

In this case, the insurance company will not pay, if the car has a boss, this time it is enough to choke.

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

Fang Huai and Xiao Hei shouted around the neighborhood, observed everywhere along the street within ten meters, and made sure that there was no one before they began to withdraw from the high-voltage electric field and began to place a guard in the fire truck parking place.

Cao Yi, the secretary general, and Jiang Jun from the rescue 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, padding their feet enough to look over there, and some people took out various photo tools to take pictures, but they were all stopped.

Fang Huai pulled off the hood of the electrical insulating suit, approached Cao Yi's side and said:

"There's no one inside, those three can't be saved, wait until the power goes out, 110 will hand over, let's withdraw."

Cao Yi looked back at Fang Huai, who had a stupid face, pulled Fang Huai to the side, and pointed to the police lane parked on the side of the road not far away:

"110 has arrived, discuss with us, let's dispose of the body.

Why, the scene is horrible and scares you out? ”

Fang Huai shook his head and didn't speak.

I just thought of the tragic situation of the three of them, and I really wanted to smoke a cigarette.

This was the first time since he was reborn that he couldn't rescue the police, and he didn't even dare to touch it.

It can only be said that people live in the world and must be persuaded.

A short time later, a yellow pickup truck from the power supply bureau arrived, and two electricians put on their gear and entered.

After a while, one came out, informing that the electricity had been cut off, and the power was being repaired, so let them go in and get the corpses out first, or it would be difficult to work.

Cao Yi beckoned: "Sun Jingwu, you get out of the car and be responsible for guarding, and a few of us will go in and deal with the corpse!" ”

In this case, it is still necessary to close the scene until the body is disposed of, and it is up to them how the police take over.

The things on the car, Fang Huai was clear, Fang Huai took a few pieces of paper cloth that the squadron used to put under the equipment area behind the car, and followed Cao Yi inside.

Many of these useless cloths were received in the car, just for the current situation.

Before the family arrives, the deceased should be covered with a cloth to prevent the family from losing control of their emotions.

Several people arrived at the scene, all with varying degrees of discomfort.

The three of them, the parts that were charred by the electric shock were all different.

The woman is slightly better, mostly on the body and neck, and the face is a little darkened, but it is still relatively intact.

The two men who were relatively close together, one had half of his face burned, the other was all burnt, and there was a large dry hole on the outside of his right calf, and his blood had already coagulated.

It's closer, and there is a scorching smell, like the smell of some rubber burning, a little sour.

Probably shoes.

Several people wore gloves and carefully carried the three to the side of the road.

Some of the injured places can't be dragged hard, and no one knows how much the electric shock will be, anyway, the fire is burned to death, and the skin is easy to break.

When he lifted the man with a burnt face, his neck was still loose, and he felt as if his head was about to fall off, which frightened Jiang Jun, who was lifted up, and wanted to scold, but he still held back.

The three of them were quickly stacked in a row.

Fang Huai untied the oiled paper cloth that had been tied up, took out three sheets, and covered them one by one.

110 and 120 arrived soon.

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

110 got out of the car and shook hands with Cao Yi.

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

Fang Huai was a little speechless.

Is she afraid? Aren't you afraid?

I'm a little scared!
