At the beginning of the fire scene, I was rescuing people, and I was broadcast live as a firefighter

After receiving Xu Liguo's arrangement, the members of the third squad immediately concentrated on the vehicles carrying concentrated sulfuric acid.

At the same time, a semi-arc simple guardrail made of sandbags is slowly taking shape.

However, leakage of dangerous liquids is not a common disaster in the first place.

Therefore, the number of sandbags stored in the fire station is not large, and the number of sandbags that can be transported by three fire trucks at one time is only less than 100.

Even the guardrail, which is made of sandbags, is only placed on the side close to the scene of the accident.

The number of sandbags is also stretched, and if there is an accident, only a knee-high guardrail on this side can only serve as a comfort.

Firefighters from the second and third squads quickly rescued the trapped people closest to the vehicle loaded with concentrated sulfuric acid.

The firefighters of the first squad began to spray some chemicals behind the sandbags.

Because they didn't know at first, the trucks labeled with Class II dangerous goods were actually loaded with concentrated sulfuric acid.

As a result, they carried an equally small amount of alkaline neutrals in their cars.

If you encounter a general leak, you may be able to make do with it.

But in the current situation, no one can guarantee how much effect these dozens of liters of calcium hydroxide can play.

And the foam of the foam car has already been sprinkled all over the scene at this time.

This was done because of concerns about a fuel leak from a car accident or an explosion that could result from a battery squeezing failure.

At this time, Li Xiao was also saving people, while thinking about how to break such an impasse.

He glanced at his empty kindness and couldn't help but regret it a little.

I really shouldn't have spent my kindness value early, otherwise I can exchange some firefighting items in the mall now.

Among them, barium hydroxide, which can smoothly carry out a non-toxic neutralization reaction with concentrated sulfuric acid, is among them.

Through the chemical reaction formula learned in high school, we can know that

H2SO4 + Ba(OH)2=BaSO4<沉淀> + 2H2O

barium hydroxide reacts with concentrated sulfuric acid, which will turn into barium sulfate precipitate and a large amount of water.

Barium sulfate forms a barrier layer, while water dilutes concentrated sulfuric acid and lowers its chemical concentration.

The price is not too expensive, 100 points of kindness can be exchanged for a ton of barium hydroxide.

The truck at the scene only has three tons of concentrated sulfuric acid, which means that only about three tons of barium hydroxide can neutralize all the concentrated sulfuric acid in the truck.

However, Li Xiao also knew that now was not the time to regret it, so he shook his head and put unrealistic ideas behind him.

However, at this moment, a pungent sour smell rushed into his nostrils.

This pungent sour smell is not only unpleasant, but also very chemically strong.

The powerful acidic substance made Li Xiao cough again and again, and the fragile lining in the nasal cavity was immediately damaged.

Of course, it was not only Li Xiao who was recruited, but all the firefighters who were close to the truck were treated the same.

The violent cough even made everyone have to temporarily stop what they were doing.

For a moment, the scene was in chaos, and there were painful coughs everywhere.

Zhang Wenxin, the captain of the third squad, and Huang Jiajie, the captain of the second squad, immediately shouted to the team members:

"Put on the breathing mask." "

Be careful, acid gas leaks!" However,

the firefighters had breathing masks, but the crowd trapped at the scene of the crash did not.

If it were the usual crowds trapped in the car, they only needed to close the windows to resist the attack of such an acid mist.

But after the serial car accident, not a single car at the scene was intact.

Moreover, around the truck, it is still the sandwich area with the most serious crash situation.

Don't talk about good damage, it's hard to find a piece of car window in the neighborhood that isn't broken.

One by one, the already injured people immediately coughed.

Seeing this situation, Li Xiao subconsciously wanted to take off the breathing mask on his face.

But his move was pressed down by Zhang Wenxin, who was quick to do it next to him.

His mouth came to Li Xiao's ear, and he shouted in the lowest possible voice:

"You guy really don't want to die, right?"

"Those were just ordinary smoke from the fire last time, and you can

smoke it when you smoke it!" "Now it's the acidic gas released by concentrated sulfuric acid, and if you take a few more breaths, your lungs will be corroded!"

"What you have to do now is to save people immediately, instead of doing senseless self-sacrifice here!".

"But .......

" "No, if even we ourselves lose the ability to rescue, then who can rescue these trapped people

?" "Even if he has a breathing mask, he can't only wait to die if he is trapped in the car

!!

?" After listening to Team Zhang's words, the struggle on Li Xiao's original face finally disappeared.

That's right, even if you can let the breathing mask out, so that the trapped people are less painful.

But because they lost the ability to save people, the trapped people could only wait for the concentrated sulfuric acid to explode, and then disappear with their car.

Thinking about the gains and losses, pros and cons, Li Xiao did not continue to be indecisive, and the movements in his hands were more diligent.

·· Dividing line...

In the live broadcast room.

"This doesn't look right!"

"No, normal concentrated sulfuric acid is not volatile.

"It is true that concentrated sulfuric acid is normal, if it is not sealed, it will absorb moisture in the air after a long period of storage, and the volume will become larger and the concentration

will be lower" "The chemistry upstairs must be half-understood, it is at room temperature and pressure, if it is under high temperature and high pressure, it will be different."

"The inner tank of the current carriage loaded with concentrated sulfuric acid is in a low-pressure environment, while the sealing layer in the middle and the outside are in a high-pressure environment.

"If the inner tank is ruptured, it is equivalent to pressurizing the concentrated sulfuric acid at the same time as the sealing layer and the outside world, and it may change from liquid to gaseous state.

"What can I do, will

the anchor be in danger now?" "How can the anchor be in danger? He's wearing a protective mask, but it's hard to say about the trapped people." "

Why are these firefighters so selfish, one by one they only bring breathing masks to themselves, do you see how uncomfortable that young lady coughs

?" "It's really three views to follow the facial features, do you go to save people if the firefighters don't wear masks?"

"As a firefighter, you should be selfless

!" "What a group of keyboard warriors!"

"Okay, okay, don't argue, the anchor is working hard to save people, you are arguing hard, are you embarrassed?".

·· Dividing line...

And the first team closest to the truck loaded with sulfuric acid, although because of the early wearing of full-body chemical protective suits.

So there was no smell of acidic gases exposed to the air, but they also noticed something was wrong.

Xie Yinglong shouted in a lost voice:

"Oh no, another crack has

appeared next to it!!" In his frightened call, a crack thicker than a fingernail appeared next to the first crack.

Several people nearby immediately cast their eyes to the position Xie Yinglong was pointing at, and their faces changed wildly, this crack was bigger, thicker and longer than before.

Some of them had better eyes, and they could even see wisps of white gas coming out of the cracks.

The faces of the first team turned ugly, and a terrible thought could not be suppressed from their hearts.

The inner tank in the carriage has reached the limit of bearing, and I am afraid that the preparation will not be able to hold up.

But everyone didn't know how to deal with it except for cold hands and feet and panic.

Hydrated lime and sand, which can neutralize concentrated sulfuric acid, have not arrived for a long time, do they have to resist it with the mortal womb of the flesh?
