Chapter 64 Concealed Poisonous Gas

This small warehouse is so full that it is not easy to find a place to leave it.

Lan Dun was a little embarrassed, and explained: "The rent of this house is cheap, and the place is a bit small, but it is basically enough. More importantly, the location is quite convenient."

In fact, Yu Fan doesn't dislike the small place, he just sympathizes with Lan Dun. The job of the courier boy is actually not easy. He runs here and there every day, and is often prone to complaints from customers who make things difficult. In fact, those who like to make things difficult for others , They are also very inferior and cowardly in their hearts, and they are usually bullied, so they can only transfer their pain to others in this way.

Lan Dun gave Yu Fan a brief introduction: "I arrange these shipments by area. These are from the south, these are from the north, and these are from those connected large and small areas." Hand gestures.

At this time, Lan Dun pointed to a small courier in the corner, probably a small paper shell, its box seemed to have been bleached, and the words on the courier slip were blurred.Lan Dun said: "The last time the courier liquid leaked, the courier items in the entire warehouse seemed to have been bleached, and there was a pungent smell. Whose is it, I have already thrown away this express, it smells too bad."

Yu Fan leaned over to take a look, and the pungent smell really came from there, and the closer it got, the stronger it became, Yu Fan asked: "Can I open this box?"

Lan Dun: "It's ok, anyway, this courier has been damaged."

Yu Fan carefully opened the box. After the box was soaked in liquid, it was already thin and soft, so it was easy to tear open.There are only two bottles inside, which look similar to household laundry detergent bottles. One of the two bottles is white and the other is orange. The labels on them can no longer be seen clearly. The bodies of the two bottles are wrapped with anti-collision foam. Yes, but the bottom of the bottle is not wrapped, the problem is the bottom of the bottle, there is a small hole in the bottom of the bottle of the two bottles, and the liquid flows out of it, it seems that the package is due to something during the transportation The reason is that the bottom of the bottle was hit or squeezed violently, which caused the bottom of the bottle to be damaged.

The liquid leaked from the two bottles mixed together and turned yellow-green, exuding a pungent smell.Yu Fan picked up the two bottles and observed them carefully, then nodded thoughtfully.

Lan Dun asked curiously: "Brother, how is it? What is it? Is it poisonous? Is it a dangerous product?"

Yu Fan stood up and said earnestly, "It wasn't considered a dangerous product in the first place, but now it is."

Lan Dun was puzzled: "It wasn't originally, but now it is again? You scholars just like to play tricks, and I don't understand what you say."

Yu Fan also smiled: "The liquid in the white bottle is colorless, and with the smell, I think it should be 84 disinfectant, that's right. The liquid left in the orange bottle is blue liquid, which should be toilet cleaner .”

Lan Dun scratched his head, puzzled: "This is our usual daily necessities, it's not dangerous, how can it have such a big lethality?"

Yu Fan continued: "It is true that there is no lethality, but it is very troublesome to mix the two liquids. The active ingredient of toilet cleaner is hydrochloric acid, and the active ingredient of 84 disinfectant is sodium hypochlorite. Two moles of hydrochloric acid and one mole of Sodium hypochlorite reacts to produce one mole of sodium chloride, one mole of water, one mole of chlorine gas. That's where the problem lies."

Yu Fan put the damaged box on top of the two bottles again, and continued: "Chlorine gas has a strong bleaching effect in a humid environment, and your room is damp and not ventilated, and there are too many express packages in your warehouse. It is made of paper, easy to absorb water, and will be bleached naturally. Moreover, the maximum allowed chlorine gas in 1L of air is 1mg. Exceeding this amount will cause human poisoning. You should throw these two bottles of liquid out quickly, otherwise it will continue to release' Toxic gas', and you have to open the doors and windows immediately, the toxicity of chlorine gas is no joke."

Lan Dun suddenly realized, slapped his thigh hard, and sighed: "It turns out you are a bad thing, see if I don't deal with you." After that, he hurriedly carried the box and walked to the door, intending to throw the box out first, but just opened it There was a crack in the door, suddenly a strange force struck, the door was pushed in from the outside forcefully, a person rushed in from outside the door, Lan Dun was defenseless, was directly bounced by the huge force, staggered backwards, He squatted down, sat on the ground, took a deep breath subconsciously, and coughed hard.

Yu Fan was also taken aback, various possibilities flashed through his mind, he subconsciously touched the weapon in his pocket that he was planning to defend himself.

"Old Yu, are you okay?" A familiar voice, a familiar figure.Yu Fan took a closer look, isn't this Chen Xingyang?
Chen Xingyang said viciously to Lan Dun who was sitting on the ground: "Boy, who do you want to deal with? Ah?" Bian raised his fist after speaking.

Lan Dun was so frightened that he took another two steps back, covering his face with his hands: "Don't...don't, it won't happen, brother, it's just an invoice, what's the point?"

It seems that Chen Xingyang heard Lan Dun say in the room that he wanted to "pack up" the express, and mistook it for Yu Fan.Yu Fan hurried forward to stop him: "Old Chen, I made a mistake, I made a mistake."

Chen Xingyang was a little dazed, put down his fist, and looked at Yu Fan carefully, he was intact, he was relieved, and asked: "I saw the message you sent me on WeChat, but I didn't see it in time at first. When I saw it, I replied to you but you didn’t respond, and I didn’t answer your phone call.”

It was only then that Yu Fan remembered to take out his cell phone to check. There were several missed calls from Chen Xingyang. He had been walking on the road just now, so he might not have heard them.

Chen Xingyang continued: "I saw your last message saying that I must find you. I had a premonition that you might be in danger, so I came here quickly."

Yu Fan patted Chen Xingyang on the shoulder, what a good brother.Yu Fan: "It's all a misunderstanding. I'm here to help this courier boy solve some problems. By the way, how do you know I'm here? Are you following me?"

Chen Xiangyang laughed loudly: "In this day and age, as long as your mobile phone is in your pocket, it is not easy for me to know where you are? In order to come to you, I didn't eat dinner, and you have to make it up to me later."

Yu Fan also smiled: "Okay, let's get up in a while." While speaking, he helped up Lan Dun who was on the ground in shock. "

Chen Xingyang curled his lips: "Eating Yongji dry pot again? Are you afraid that you have invested in this dry pot restaurant?", looking at Lan Du who stood up, Chen Xingyang went up to pat the ashes on his pants: "Brother, I'm sorry just now."

Lan Dun smiled cheerfully.Yu Fan said to Lan Dun again: "Okay, the cause of the problem has been found, and the matter has come to light. From now on, you must pay more attention to chemicals such as laundry detergent, 84 disinfectant, and toilet cleaner, pack them well, and don't leak them again. Sometimes some seemingly harmless daily necessities can be fatal when mixed together."

Lan Dun was very grateful to Yu Fan.Yu Fan and Chen Xingyang said goodbye to Lan Du, and the two left. According to the agreement, they bravely remembered the dry pot and treated Yu Fan.

The tea was poured, and the two sat opposite each other. Yu Fan picked up the tea and said with a smile, "Come on, I'll replace the wine with tea, thank you Lao Chen for caring about me."

Chen Jiayang also smiled and picked up the tea, touched it, took a sip, and suddenly his face became very serious: "Old Yu, do you have something to hide from me?"
