At the beginning of the fire to save people, I was broadcast live as a firefighter

After receiving Xu Liguo's arrangement, the members of the third team immediately gathered towards the vehicle carrying concentrated sulfuric acid.

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

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

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 a time is less than 100.

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

The number of sandbags is also limited. If there is an accident, there is only a guardrail that is less than knee height on this side, which can only serve as a comforting effect.

The firefighters of the second and third teams quickly rescued the trapped people closest to the vehicle loaded with concentrated sulfuric acid.

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

Because they didn't know it at the beginning, the truck marked with the second-class dangerous substance was actually loaded with concentrated sulfuric acid.

As a result, the amount of alkaline neutralizers they carry on board is also low.

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

But in the current situation, no one can guarantee how effective these dozens of liters of calcium hydroxide can be.

The foam from the foam car had already been sprinkled all over the scene at this time.

The reason for this is the fear of a fuel leak caused by a car accident or a possible explosion caused by a faulty battery squeeze.

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

He glanced at his empty goodness value and couldn't help feeling a little regretful.

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

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

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

h2so4+ba(oh)2=baso4<沉淀>+2h2o

Barium hydroxide reacts with concentrated sulfuric acid to form barium sulfate precipitate and a large amount of water.

The barium sulfate forms a barrier layer, while the water dilutes the concentrated sulfuric acid, reducing its chemical concentration.

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

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

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

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

This pungent sour smell is not only unpleasant, but also very strong in chemical nature.

The powerful acidic substance made Li Xiao cough repeatedly, and the fragile inner membrane in the nasal cavity was immediately injured.

Of course, it wasn't just Li Xiao who was recruited, but all firefighters who approached the truck received the same treatment.

The severe cough even made everyone temporarily stop their work.

For a while, the scene fell into chaos, and painful coughing was everywhere.

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

"Put on a respirator."

"Be careful, the acid gas is leaking!"

While the firefighters had breathing masks, those trapped at the scene of the crash did not.

If it were the people trapped in the car at ordinary times, they only need to close the windows to resist the attack of such acid mist.

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

What's more, the area around the truck is still the most severely damaged area.

Not to mention intact, it is difficult to find a car window that is not damaged around here.

The people who were already injured immediately coughed.

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

But his move was suppressed by Zhang Wenxin, who was beside him with quick eyes and quick hands.

He put his mouth close to Li Xiao's ear, and shouted in the lowest possible voice:

"You guys really don't want your life, right?"

"The last time the fire was just ordinary thick smoke, just smoke it!"

"What's present is the acid gas released by concentrated sulfuric acid. If you take a few more breaths, your lungs will be corroded!"

"What you have to do now is to rescue people immediately, instead of making unnecessary self-sacrifice here!"

"but......."

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

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

!!!

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

That's right!Even if I can let out the breathing mask, it will make the trapped people less painful.

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

After thinking about the pros and cons of the pros and cons, Li Xiao did not continue to be indecisive, and worked harder with his hands.

··Dividing line··

in the live room.

"This situation 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 time of storage, and its volume will increase and its concentration will decrease."

"I must have learned a little about the chemistry upstairs. It was under normal temperature and pressure. It would be different if it was under high temperature and pressure."

"Currently, the tank containing concentrated sulfuric acid is in a low-pressure environment, while the sealing layer in the middle and the outside world are in a high-pressure environment."

"If the inner tank breaks, it means that the sealing layer and the outside world pressurize the concentrated sulfuric acid at the same time, and it may change from liquid to gas."

"What can I do? Will the anchor be in danger now?"

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

"Why are these firefighters so selfish, and they only wear breathing masks for themselves. Do you see how uncomfortable that young lady is coughing?"

"It's true that the three views follow the five senses. Are you going to save people without the firefighter wearing a mask?"

"To be a firefighter is to be selfless!"

"What a group of keyboard warriors!"

"Okay, okay, stop arguing, the anchor is working hard to save people, and you are fighting hard. Are you embarrassed?"

··Dividing line··

The first team, which was closest to the truck loaded with sulfuric acid, was wearing a full-body chemical protective suit early on.

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

Xie Yinglong lost his voice and shouted:

"Not good, another crack appeared next to it!!!"

In his terrified cry, a crack thicker than a fingernail appeared next to the first one.

Several people nearby immediately turned their eyes to the position Xie Yinglong was pointing at, and their faces changed wildly. This crack was bigger, thicker and longer than the previous one.

Some have better eyesight, and even wisps of white gas can be seen emerging from the gaps.

The faces of everyone in the first team became ugly, and a terrible thought came out of their hearts uncontrollably.

The liner in the carriage has reached its limit, and I am afraid that it will not be able to hold it.

But other than having cold hands and feet and panicking, everyone didn't know how to deal with it.

The slaked lime and sand that can neutralize concentrated sulfuric acid have not yet arrived. Are they going to use their mortal bodies to resist?
