A fire broke out in the basement of the Peking University School of Life Sciences, and some laboratories were damaged. The fire site was one of the zebrafish water body laboratories. Thousands of fish died, accounting for about 2/3 of the total. The cause of the accident was suspected to be the aging and short circuit of the water circulation system. For this reason, some doctoral students may delay graduation due to loss of data.
Laboratory fire student rescues zebrafish
The building of the Academy of Life Sciences is located near the East Gate of Peking University. Its basement "fish room" is one of the largest zebrafish water laboratory in Asia.
According to informed students, at 0 o'clock in the morning on the 18th, they successively received phone calls from classmates to inform Yufang of the fire and hurried to rescue. When arriving at the building, several fire trucks were lined up in front of the door and were blocked by the cordon.
When the fire was under control, almost all the students related to the experiment were present. After waiting for the firefighters to evacuate, they put on gas masks and flashlights in batches and rushed to the scene to rescue them. The student recalled, "We are all worried about the safety of (zebra) fish. The smoke inside is very heavy, and the fish box is covered with thick soot. When the lid is opened, the zebrafish are smoked and float on the water. Everyone Very sad. "
2/3 fish death subject affected
According to the students, the zebrafish water laboratory is equipped with fish boxes of various sizes, which contain zebrafish of various ages, ranging from small fish eggs to large adult fish. These fish are used for experiments. Because the zebrafish has a short cultivation period and transparent appearance, it is easy to observe the phenomenon, so it is used to study the growth and development of the human body. The cultured fish is suitable for the research of undergraduates, graduate students, and doctoral students. In the accident, thousands of fish were burned to death, accounting for two-thirds of the total. Due to the heavy loss of samples, everyone needs to re-make the corresponding samples. "Some doctors' research is more complicated, and the observation period is longer. It takes relatively more time. Re-study of new samples may cause them to postpone graduation."
At present, the school has sent e-mails to students of the college to remind students to pay attention to the safety of circuits in the laboratory.
Official statement
At around 23:20 on June 17, the security guard of the School of Life Sciences discovered a large amount of smoke from the zebrafish house on the ground floor during the patrol. It immediately reported to the school's security department and organized the evacuation of the building. The emergency unit of the Ministry of Security and the police station immediately rushed to the scene to deal with it, and dialed 119 to call the police. When the firefighters arrived, there was no open flame, but the smoke was heavy. After disposal, the fire was eliminated and there were no casualties. The fire brigade preliminarily judged that the thick smoke was caused by the burning of the power box of the zebrafish house, and the fire site has been protected. The cause of the fire is subject to further investigation and determination by the fire investigation section of the Beijing Fire Bureau.
After overnight rescue, some experimental zebrafish were moved to a safe location, minimizing losses. According to the person in charge of the laboratory, the zebrafish transgenic technology and gene site-directed mutation technology are very mature. There are no technical obstacles to the various strains of zebrafish needed to reconstruct the experiment. Zebrafish of important strains have frozen sperm storage There is a need to be able to recover at any time. In addition, there are many important commonly used fish lines. Many laboratories at home and abroad have farmed. Currently, many domestic and foreign counterparts have said that they can provide these fish lines at any time. Subsequent inventory and sorting work is currently being carried out in an orderly manner. It will take some time for the laboratory to restore the normal operation of the entire zebrafish system. Although it is not yet possible to accurately estimate the length, the impact on the postgraduate studies of the laboratory is not without Recoverable.
