Ye Zhenzhen watched Nan Zhiqiao close the door of the laboratory and lock it, and then pasted the paper just now in a conspicuous position on the glass wall: "Biological danger, no entry!"

Ye Zhenzhen asked, "What are you doing?"

"Basic steps in the emergency response to a terrorist attack. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ”

Seeing Nan Zhiqiao busy, Ye Zhenzhen was a little dazed and couldn't intervene.

Nan Zhiqiao used the landline in the laboratory to make a call, and the first thing was to inform Professor T, who was the big boss of the experimental group and the person in charge of biosafety in the entire laboratory, and was the first person to be notified if there was a problem.

The two hurriedly said a few words on the phone, and Nan Zhiqiao hung up the phone with a heavy face.

Ye Zhenzhen asked, "What is the situation now?"

"Professor T will inform the staff of the relevant departments that the two of us will be quarantined in place. ”

"What does 'quarantine in place' mean?"

"Don't you know the steps of emergency response? Why is the concept of in-place isolation unclear?"

Ye Zhenzhen defended: "I haven't studied the course of terrorist attack emergency response, how do you know, I also said it by feeling just now." ”

"Ordinary colleges and universities don't offer this course, if you want to learn, you have to study on your own, and I suggest a reference book for you, "Response and Disposal of Bioterrorism". ”

Nan Zhiqiao said lightly, Ye Zhenzhen listened carefully, and thought to herself, at such a terrifying and tense moment, Nan Dashen is still in the mood to say that the reference book is worthy of being a great god.

Nan Zhiqiao found two sets of biosafety protective clothing, one set was thrown to Ye Zhenzhen, and one set was worn by himself.

Ye Zhenzhen followed Nan Zhiqiao's example, put the white biosafety protective suit on her body, and wondered, "Are we going to experiment with this equipment?"

"Yes, deal with the white powder and do pathogen testing by the way. ”

Nan Zhiqiao put the newspaper back into the box with white powder and ice packs, and then wrapped two layers in a yellow plastic bag with biosafety markings, and pointed in the direction of the P3 laboratory.

Ye Zhenzhen understood, "Can I go in too?"

Nan Zhiqiao nodded, "Although you don't have authorization, but in extraordinary times, in times of emergency, you can learn and use it now." ”

Nan Dashen is going to personally demonstrate the operating procedures of the P3 laboratory, and the excitement slightly dilutes Zhen Zhen's nervous mood.

Ye Zhenzhen followed behind Nan Zhiqiao and walked towards the P3 lab.

After a long hallway, P3 Lab is at the end.

Although the P3 laboratory is connected to the ordinary P1 laboratory through a long corridor, its building structure is independent and self-contained.

Nan Zhiqiao first put the carton into the sample channel, and then took Ye Zhenzhen into the buffer room.

In the buffer room, the automatic disinfection device sprays a mist of disinfectant, which has a somewhat pungent smell.

After the disinfection of the buffer room, the two entered the changing room and changed into P3 laboratory protective clothing.

After disinfection again, through two biosafety doors, the two entered the experimental area of the P3 laboratory.

The experimental area is square, with a biological safety cabinet on each side, a wide test bench in the middle, and several commonly used instruments on one side of the test bench: PCR instrument, centrifuge, ultra-low temperature freezer, liquid nitrogen tank......

Nan Zhiqiao took the packaged carton out of the sample channel, put it in the biosafety cabinet, and instructed Ye Zhenzhen to observe it from a distance of one meter behind her.

Ye Zhenzhen asked, "Why do you want to stand at such a distance, I can help." ”

Nan Zhiqiao explained: "Standing at a distance of one meter outside the biosafety cabinet, in order to prevent interference with the surrounding airflow, this time it is a sub-packaging sample, I can alone, when I want you to do something, I will naturally call you, now you pay attention to observe my operation." ”

Ye Zhenzhen remembered that when she was in junior high school, the first time she entered the laboratory, the teacher was like this, for fear that the students would make mistakes, so she just let me look at it, Nan Zhiqiao regarded herself as a junior high school student.

The samples were quickly divided into portions, each of which was packaged, one of which was layered and placed in a small shipping box.

"Do you want to take this sample out?" asked Ye Zhenzhen.

"Well, send it outside for testing. ”

"Didn't our lab do the pathogen testing for this sample ourselves?"

"We have a limited range of kits in our lab, and the biosafety level here is not the highest. ”

The variety of kits is limited, which is understandable, the experimental group has several fixed research objects, there are so many pathogenic pathogens, and it is impossible to have all the detection reagents, but "the biosafety level is not the highest", Zhen Zhen is a little puzzled, isn't this P3 laboratory the laboratory with the highest biosafety level at the Institut Pasteur?

Ye Zhenzhen said the question in her heart, Nan Zhiqiao frowned, and the expression on her face seemed to say, I don't know such a simple question.

Zhen Zhen immediately regretted it, as if she had asked a low-level question, her original intention was to ask, the sample was to be sent out of the Pasteur Institute, but the question she asked became as if she didn't understand the level of the biosafety laboratory, but after a while, Nan Zhiqiao patiently explained: "The biosafety laboratory is divided into four levels, P1 to P4, and the biosafety level is gradually increasing, we are here in the P3 laboratory, and there are P4 laboratories with a higher security level. ”

"Where is this sample going to be sent to P4 labs?"

"Lyon, the second largest city in France, is home to the world's most advanced P4 laboratory, the Jean Merrieux laboratory. ”

Before going abroad, she had seen a report on TV that China's only public P4 biosafety laboratory was built in Wuhan, and later, when I read comments on the Internet, they all said that the P4 laboratory configuration in Wuhan was some distance worse than that of a Jean Merrieux P4 laboratory in France.

I don't know, after a check, Zhen Zhen was also convinced, this Jean Merrieux P4 laboratory, named after a vaccinator, the experimental building is an all-glass structure, the interior is fully controlled by a computer, and there are voice assistants to help, 15 safety doors, the entire laboratory covers an area of 600 square meters, the main operation area has 60 square meters, there are 2,000 animal materials, the safety buffer zone is three kilometers in the center of the laboratory, the buffer zone has the French permanent army to ensure safety, and set a five-kilometer no-fly zone. As the world's most advanced biological laboratory, Jean Merrieux preserves all the pathogens that humans can collect.

In the past, Ye Zhenzhen only learned about it from the Internet, but now it is related, thinking of Jean Merrieux's biosecurity level, Zhen Zhen has another layer of fear about this uncertain bioterrorism incident.

After disinfection, through the security doors, the two changed into protective clothing and walked out of the P3 laboratory.

Nan Zhiqiao took out the sample box to be sent away from the sample channel and walked all the way through the corridor between P1 and P3.

Walking back to the familiar P1 laboratory, Ye Zhenzhen was stunned.

Ye Zhenzhen and Nan Zhiqiao had only been in the P3 laboratory for an hour, and the outside of the laboratory building had been turned upside down beyond recognition.

Cordons and rows of heavily loaded policemen surrounded the entire experimental building.
