Summary

Taking care of our safety and health during experiments not only protects us from injury and illness but can it also lower the possibility of getting injuries and illnesses. During the first day of experimenting, we listened to a lecture from professor Zhang talking about safety and devices. She led us to the lab and introduced all the instruments we might use during our experiment. She then instructed us on biosafety precautions, including the necessity of wearing rubber gloves, a lab coat, and a mask during the experiments to protect us and prevent the contamination of the experimental reagents. We were also instructed to wash our hands after conducting experiments because this can help us to get rid of germs and bacteria. To have a safer experimental procedure, our teammates and the teachers would occasionally admonish us when we were not adhering to the safety standards. In conclusion, we finished all our experiments by following the safety guide.

 

Personal habits 

1 Keep the environment clean and don’t bring any daily necessities and food into the labs.

2 Girls must tie their hair up to prevent contaminating the bacteria or touching the chemicals.

3 Wear lab coats and gloves.

4 Don’t use gloves to touch personal items, elevator switches, or any other things unrelated to the experiment.

5 Train first, and then operate.

6 Don't smell, taste, or touch any chemicals and reagents up close.

7 Clean the experimental items as well as sewerage system regularly.

8 Waste chemicals should be poured into special tanks, don’t dump chemicals into the sink.

9 Sharp or blunt instruments should be placed in a safe place to prevent possible injury.

10 Dispose of experimental waste by following the standard.

11 Be cautious of fire and electric shock.

12 Prevent poisoning.

13 Conform strict sterile procedures to avoid infection.

14 Protect yourself against ultraviolet lights.

15 After the sample is made, make sure it is labeled in time, including the time of manufacturing, the sample name, the name of the producer, etc.

16 Experimenters should disinfect their hands before entering and leaving the laboratory and should wash their hands regularly during the experiment.

17 If an accident happens, researchers should report to the instructor in time.

18 Electric appliances should be turned off before leaving.

19 After completing the experiment, the test bench should be cleaned, and the waste should be carefully disposed.

 

Special Rules:

1 Working hour is 8:30-18:00, from Monday to Friday.

2 When entering the lab, dress neatly and wear a white coat lab coat.

3 Eating or storing food in the lab is prohibited.

4 Personal belongings should be kept properly.

5 Obey the instruction from laboratory personnel.

6 Avoid making a loud noise, smoking, eating food, or littering in the laboratory.

7 Liquid and solid waste should be collected separately and stored at the designated place.

8 The operation of the advanced instruments should be completed under the supervision of the teacher.

9 Do not touch the scientific instruments in the laboratory without permission.

 

COVID-19 prevention requirements:

1 Complete the required nucleic acid tests regularly.

2 The laboratory should be disinfected and ventilated as often as possible.

3 Wear masks in the laboratory to prevent the spread of the virus.

4 The COVID-19 vaccination should have been completed before entering the laboratory.

5 Report any abnormalities or accidents in time and stop working immediately.

 

 

Requirements for biological waste:

For waste liquids, we collect them uniformly in the waste tank and eventually rinse them into the laboratory hand-washing sink. Discarded solids, such as ribose gel, gun tip, etc., are uniformly thrown into the trash can and collected and discarded by professional staff.

 

Requirements for handling biological samples in experiments:

To prevent misuse, the biological samples we collect—including RNA, protein, probes, breast cancer cells, etc.—will typically be stored in the refrigerator and appropriately labeled with the name of our instructor. The remainder of the samples, including the LB solution, will be sterilized in a chamber before being taken out and set on a bench to cool. After that, the aftermath is carried out in accordance with the requirements for the treatment of biological waste.
