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

As the barium hydroxide in the sky rose and fell, Li Xiao could feel the tingling from his skin getting stronger and stronger.

click, click...

A few slight shattering sounds of glass came from inside the compartment.

Li Xiao felt his heart beat a little faster, and he could clearly understand where the sounds came from. It was the glass liner filled with three tons of concentrated sulfuric acid that shattered.

Glass shattered, one after another.

In less than two seconds, a puff of white smoke rose from the metal carriage.

The concentrated sulfuric acid flowing out of the inner tank instantly corroded a hole the size of a fist on the outer wall of the carriage.

The appearance of concentrated sulfuric acid is like water, without any color.

But the corrosiveness is extremely terrifying, and the land it passes through is a mess.

In just a few breaths, the hole that was originally the size of a fist suddenly became the size of a head, and it continued to expand and spread.

However, a thick layer of barium hydroxide has already been spread around the carriage, and the transparent concentrated sulfuric acid and the white barium hydroxide react when they come into contact with each other.

However, the reaction is not violent. After all, barium hydroxide is the best neutralizer for concentrated sulfuric acid.

Barium hydroxide + concentrated sulfuric acid → barium sulfate + water

The original white barium hydroxide undergoes a rapid displacement reaction, forming a layer of protein-colored substance at the position in contact with concentrated sulfuric acid, and the volume begins to expand continuously.

During the reaction between barium hydroxide and concentrated sulfuric acid, a large amount of heat is released.

A wave of heat spread from around the carriage to the surroundings. Even though Li Xiao was seven or eight meters away from the reaction center, he could still feel the heat from the carriage.

Seeing this scene, Li Xiao heaved a sigh of relief, the inner tank was damaged better than everyone expected.

At least for now, it's not too serious.

From the flow of concentrated sulfuric acid continuously flowing out of the compartment, we can actually infer how big its source is.

He did a little visual inspection, and the current flow was about the amount of a 500ml bottle of mineral water flowing out every second.

Not too small, but completely within the acceptable range.

At least the current situation is much better than what they had expected, when the liner exploded and the three tons of concentrated sulfuric acid inside overflowed to the surroundings at the same time.

But no one dares to take it lightly. After all, once glass is broken, it will easily fall apart.

No one knows if the entire liner will explode in the next second.

Everyone waited in suspense, while more and more barium hydroxide was transported to the outermost line of defense.

Concentrated sulfuric acid reacts stably with barium hydroxide, producing a large amount of water, a large amount of sediment, and a large amount of heat.

The white solid piled up next to it was less and less, and a large amount of off-white barium sulfate appeared at the same time.

Li Xiao wiped the sweat from his forehead, a lot of heat released from the chemical reaction.

It even made him feel that what he was in now was not an empty viaduct, but a closed fire scene.

However, he was a little fortunate to be able to wait here peacefully for all the concentrated sulfuric acid and barium hydroxide to be neutralized.

Since the line of defense is designed to surround three and miss one, the concentrated sulfuric acid that has no time to react chemically flows towards the gap.

The concentrated sulfuric acid is undergoing chemical reactions while flowing towards the gap.

The chemical reaction produces sediment and large volumes of water that are mixed with concentrated sulfuric acid to become less harmful dilute sulfuric acid.

Continue to flow to a lower place.

However, in farther places, the firefighters have long been prepared to kill a large layer of barium hydroxide, and they can be safely neutralized when the dilute sulfuric acid flows through.

Everything is going on step by step, and concentrated sulfuric acid is constantly flowing out, and it is constantly reacting with barium hydroxide to form sediment and water.

in the live room.

Seeing that the carriage was finally corroded by concentrated sulfuric acid, everyone was a little panicked.

But when everyone saw that the concentrated sulfuric acid did not explode, it corroded the surrounding firefighters into a plume of blue smoke.

Instead, it quietly flowed out from the bottom of the carriage like a good baby.

Everyone was nervous all the way, and finally let go.

"Great, luck in misfortune!"

"All thanks to the boss who generously provided the barium hydroxide!"

"The boss is big, the boss makes a fortune!"

"Indeed, if the boss hadn't provided it in time, the asphalt floor next to the carriage might have been corroded long ago."

"It's a pity that the boss of Guangxing Chemical Factory didn't start the live broadcast, otherwise I would have gone over and rewarded him with a few rockets!"

"Actually, we don't just want to thank the boss, but also those veterans who helped deliver the barium hydroxide."

"Indeed! Everyone helped me as much as I could"

"If every disaster happens, everyone can work together and come to our country to deal with any difficulties!"

··Dividing line··

After relaxing, Li Xiao finally glanced at the live broadcast room in the corner of his sight.

Seeing everyone's messages warmed his heart.

It is true that the slaked lime and sand that had been prepared in advance were delayed, and the barium hydroxide that was temporarily applied was even more distant.

Fortunately, the big brother in the live broadcast room generously supported so much barium hydroxide, and fortunately, the audience who just saw the live broadcast gave their best help.

Otherwise, I can't imagine how this accident will develop.

Li Xiao looked at the hole in the carriage again. The flow of concentrated sulfuric acid did not expand, and the reaction was very stable.

He quickly adjusted his clothes and said to the audience in the live broadcast room:

"Thanks to the veterans for their support, and especially to the boss of Guangxing Chemical Factory for their help in times of crisis."

"This batch of barium hydroxide really came too timely. Without the help of the eldest brother, we are really helpless."

"We will report the consumption of this batch of barium hydroxide to the leader as soon as possible for reimbursement."

"If there is any economic loss during the period, we will also give sufficient compensation here."

"Of course it doesn't mean that I look down on Big Brother's help, I'm just worried that the batch of barium hydroxide we temporarily seconded will delay the construction schedule of Big Brother's factory and cause losses.

"After all, we can't let our enthusiastic people give us help, but we have suffered heavy losses."

"In addition, I would also like to thank all the brothers and sisters who drove to help transport the barium hydroxide, as well as the brothers and sisters who went to the factory to help transport it."

"Thank you, I really appreciate your help."

"This rescue can be so smooth, it all depends on everyone's concerted efforts, if there is no step, our rescue will fail this time."

"The success of this rescue is a success for all of us and I'm so proud of you!"
