Chapter 3: Safety No. 1

　　 Xu Qiu hurriedly clicked on the email to check.
　　##
　　RE: Research group internship
　　 Yes. Come to my office for an interview this afternoon. Materials in Room 218 on the first floor.
　　 Wei Xingsi
　　##
　　 Xu Qiu opened the course selection website and checked his class schedule.
　　 Seeing that there was no class this afternoon, he quickly replied to the email.
　　##
　　RE: RE: Research group internship
Ok. Then I will arrive at your office around two o'clock in the afternoon.
　　 I wish you success at work and good health!
　　 Xu Qiu
　　##
　　 Xu Qiu closed his mailbox and switched back to the homepage of Mr. Wei's research group to focus on the research content and research results.
　　The research content is in both Chinese and English. There are many professional terms in it, but some of them have appeared in professional courses. Therefore, with the translation of You Pi and Gu Gou, there are not many obstacles to reading.
　　…………
　　 After preparing, Xu Qiu arrived at the first floor of the material ten minutes early.
　　 This is an old building that has been built for more than 20 years. The building is covered with traces of time.
　　 Teacher Wei's office is at the end of the corridor on the second floor.
Xu Qiu walked in the slightly dim corridor. There were a few lights above his head that were still on and off. A greenish "safe passage" sign hung on the wall below his feet, and I didn’t know what equipment he heard. The hum of operation.
　　 Hey, weird, when can the school renovate the old building?
　　 Room 218 arrived, Xu Qiu stopped.
　　 The office door is bluffing, and a slight light shines through the cracks in the door.
　　 Xu Qiu took a deep breath and slowly knocked on the door three times.
　　 "Please come in!"
　　 An energetic male voice came from the door.
　　 Xu Qiu gently pushed the door in, and looked around a little.
　　 A house of more than 20 square meters has two desks, a bookcase, a sofa bed, a few chairs, and a fish tank that is "cuckling clamshell".
　　 A middle-aged man is sitting at the desk facing the door. It must be Teacher Wei Xingsi.
　　 Teacher Wei is about forty years old, with piercing eyes.
　　 When he saw Xu Qiu coming in, he stopped working, with a smile on his face.
　　 Xu Qiu closed the door, stood still, and explained directly:
　　 "Hello, Teacher Wei, I contacted you this morning, Xu Qiu, a junior in the Department of Materials Science."
　　 Teacher Wei smiled, and pointed to the chair next to him and said, "Xu Qiu, sit down first."
　　 The two asked and answered.
　　 "What kind of professional?"
"material chemistry."
　　 "How are your grades and what are your grade points?"
　　 "It is 3.46 now, ranking third in the material chemistry major."
　　 "Oh, isn't it? That's amazing." Teacher Wei replied, getting up and taking out two boxes of honey grapefruit tea from the refrigerator behind him.
　　 He opened one box himself, and handed the other box to Xu Qiu, and said:
　　 "In June, the sky is getting hot, come and have a drink."
　　 "Thank you." Xu Qiu took it. It was cold, he thought about it and still didn't open it.
　　 Teacher Wei didn’t care, and continued:
　　 "I recently decided on an undergraduate undergraduate program, one year older than you, also majoring in materials chemistry, and the grade point seems to be similar to yours.
　　 She is preparing for her graduation defense recently, and she doesn't come to the laboratory much. You can see each other when you have the opportunity. "
　　 Teacher Wei paused, and suddenly said, "Xu Qiu, are you interested in coming to me to study graduate school?
　　 You should apply for the undergraduate program. It is not a problem to apply with your grades. "
　　 Xu Qiu scratched his head and replied: "I'm sorry, Teacher Wei, I haven't considered such a far away."
　　 "That's okay." Wei Xing thought:
　　 "Then you do it here first, looking for feelings, there is still more than a year to consider."
　　 "Yeah." Xu Qiu nodded.
　　 "Okay, you go to the next 216 laboratory and call Chen Wanqing over."
　　 He was waiting to get up, and heard Teacher Wei say: "I'll take you there, come with me."
　　…………
　　 The room types of 216 and 218 are similar.
When 　　 entered, there was a large desk for students' office use, and then a transparent glass wall as a partition. At the other end of the glass wall was the laboratory, filled with various experimental equipment that Xu Qiu didn't recognize.
　　 Wei Xingsi introduced:
　　 "The space here is relatively small now, but on the new campus of Zhangjiang, we still have a large laboratory, which is currently under construction."
　　 Then, he pointed to the girl who was sitting at the desk operating the computer and said:
　　 "This is my PhD student, Chen Wanqing, Xu Qiu, please follow her first."
　　 Xu Qiu looked at Chen Wanqing. Although she was a Ph.D. sister, she looked like she was just in her early twenties.
　　 Maybe it's a direct Ph.D student?
　　 He took the initiative to say hello: "Hello, Sister Chen Wanqing."
　　 "Hello, brother." Chen Wanqing stood up and responded.
　　 Teacher Wei patted Xu Qiu on the shoulder and said:
　　 "Okay, then you talk, I'll go back to the office first."
　　 I don't know if it was an illusion, Xu Qiu found that Chen Wanqing felt relieved after Teacher Wei left.
　　 But it was the first time we met after all, so it was difficult for him to ask directly.
　　Senior sister seemed to be relatively cold, she didn't speak, but looked at Xu Qiu curiously.
　　 He had to take the initiative and introduce himself again:
　　 "Hello, senior sister, I am a junior in the Department of Materials Science, Xu Qiu. I want to come here for an internship. I have already talked with Teacher Wei just now."
　　 "Okay," Chen Wanqing nodded slightly and said, "Are you okay with the wait?"
　　 "It's okay, there is no class this afternoon."
　　 "Okay, let's go to the supplies department first."
　　…………
　　 On the way, Xu Qiu looked through the history of system information.
　　 [The task has been completed, get 100 points, access level +1. 】
　　 [The current permission level is level 1, and the proficiency system, auxiliary system and deduction system are enabled. 】
　　【Get the Novice Mission II. Raise the proficiency rating of any experimental operation to level 3 or above, and reward 100 points for task completion. 】
　　 Seeing the three newly opened system functions, Xu Qiu was a little excited.
　　 After turning on the auxiliary system, he can get real-time operation instructions when he is doing experiments, and he can also exchange points for higher-level guidance
　　 Why can't the experimental technology be improved quickly?
　　 At the material office, Chen Wanqing reported her name, student ID and Wei Xingsi's name, and signed the receipt.
　　 Then, she got two lab coats of 165 and 180 yards, 5 bags of disposable PE gloves, 1 box of disposable syringes, and 100 magnetic stirrers the size of rice grains.
　　 "Do you need to pay for things here?" Xu Qiu said.
　　 "Our group keeps accounts here, and settles on a monthly basis, and we go directly to the project funds." Chen Wanqing explained.
　　 "That's it, is the elder sister a direct Ph.D student in this school?" Xu Qiu asked.
　　 "No, my master's degree was at East China University, and I took the exam from there."
　　 Xu Qiu nodded, and took the initiative to help Chen Wanqing pick up the supplies she had just received, and said: "Senior sister looks young, it feels like she has just graduated from a bachelor's degree."
　　 "Nothing," Chen Wanqing covered her mouth with a chuckle, and said, "Xu Qiu, are you planning to study in this school?"
　　 "Yes, I just submitted an application to the instructor for the research program a few days ago." Xu Qiu said.
　　 The two became acquainted a lot, and went back to the laboratory chatting all the way.
　　…………
　　 "The first lesson of introductory education, safety education. UU reading www.uukanshu.com"
　　 Chen Wanqing opened the "Laboratory Safety Education" PDF file on the computer desktop and began to read.
　　 "First of all, you must wear laboratory clothes, disposable activated carbon filter masks, disposable PE gloves, and wash your hands before and after the experiment."
　　 "Secondly, you can't wear skirts and high heels, uh... sorry," Chen Wanqing said embarrassingly: "Forget that you are a boy. There are more girls in our laboratory."
　　 "Hey, this is too long, you should watch it yourself." Chen Wanqing pushed the laptop to Xu Qiu, and added:
　　 "The most important point is that there may be residues of toxic and harmful drugs in every corner of the laboratory, so you must protect yourself."
　　 Xu Qiu nodded and took the computer.
　　 There are many experiment courses in his undergraduate course, including "General Chemistry Experiment", "Basic Physics Experiment", "Analytical Chemistry Experiment" and so on.
　　 He is naturally no stranger to laboratory safety education.
　　 I have also heard about the laboratory safety accidents that have occurred in recent years.
　　 For example, a senior in the chemistry department exploded one arm when using the hydrothermal kettle due to improper operation.
　　 A postgraduate student of the Department of Materials poured experimental waste of lithium-ion batteries directly into the sewer, triggering a fire alarm.
　　 A research group in the Department of Physics exploded due to improper storage of steel cylinders. At that time, it was like an earthquake, and the entire building felt obvious.
　　 A graduate student in the polymer department was doing a synthesis reaction, and the reaction vessel caught fire. In a hurry, he threw the reaction vessel out of the building directly through the window, but fortunately no casualties were caused.
　　 So Xu Qiu summarized his own laboratory survival guide:
　　Life safety first, instrument safety second;
　　 The situation is not right, and immediately ran away.
