November 25, 2022 at 2:00 pm, in the School of Resources and Environmental Engineering, Building 25, A105 laboratory held a laboratory high-pressure gas cylinder (argon) leakage emergency exercise activities, teachers and students involved in this exercise are the Asset and Laboratory Management Department and the College Experiment Center. of the experimental teachers, graduate student instructors, Laboratory supervisor, as well as some graduate students, undergraduates, the activities of the laboratory safety emergency drill professional laboratories to participate in the whole process of guidance.

The emergency drill was divided into two parts. Firstly, the engineer  introduced in detail the professional knowledge related to high-pressure  gas cylinders in the laboratory to the teachers and students  participating in the drill, helped them learn and master the use of  high-pressure gas cylinders and precautions, understand the storage,  stacking and transportation requirements of gas cylinders, and recognize  the common high-pressure gas cylinders' indicator signs. At the same  time on the potential dangers of high-pressure gas cylinders to focus on  tips: for example, high-pressure gas cylinders due to improper  operation of the container material leakage will cause experimental  personnel to suffer from mechanical injury, frostbite, or asphyxiation  and other injuries; encountered when the tipping, falling or collision,  easy to trigger a physical explosion; encountered at high temperatures,  easy to cause the increase in internal pressure of cylinders can cause  cracking and explosion and other injuries. And especially remind  everyone, when the high-pressure gas cylinder accident, due to the  rescue difficulty, professionalism, complexity of the accident scene and  other factors, once the rescue operation is not appropriate, the  accident scene personnel are vulnerable to oxygen deprivation,  frostbite, explosion and other dangerous secondary injuries.

Immediately after the laboratory high-pressure gas cylinder (argon)  leakage accident emergency exercise activities under the guidance of the  exercise engineers officially began: from the discovery of  high-pressure gas leakage (fainting students), the first time to open  the laboratory doors and windows, to report to the Head of the  Laboratory, Head of the College, the school laboratory safety  management, and then to the emergency incident Rescuers enter the scene  to remove the source of danger, medical personnel to implement rescue,  and finally complete the emergency accident investigation report.  Teachers and students participating in the drill completed the first  task of the drill according to the requirements, and at the same time  learned the professional use of positive pressure air respirator.

The development of this emergency drill activities to help  experimental teachers and students in practice to master the correct  handling of high-pressure gas leakage, improve the emergency protection,  self-help and collaborative rescue capabilities; to further strengthen  the safety awareness, and deepen the understanding of the importance of  safe experiments.
