The 2021 Laboratory Culture Month of Chongqing University was successfully held

In order to strengthen the construction of laboratory safety culture and continue to promote cultural education, Chongqing University launched a laboratory safety culture month activity with the theme of "Improving Laboratory Safety and Building Safety Together". On December 21, the "2021 Chongqing University Laboratory Culture Month" event jointly organized by SYSBEL and the School of Materials Science and Engineering of Chongqing University was successfully held in the laboratory building of Chongqing University.

Chongqing University Laboratory Safety Culture Month Launching Ceremony

At the launching ceremony, vice president of the School of Materials Science and Engineering, Chongqing University, Chen Zejun emphasized the need to establish the concept of laboratory safety management, strengthen the construction of laboratory culture, and do a good job in laboratory safety. Through the combination of theory and practice, major teachers and students can strengthen laboratory safety management, spread laboratory safety culture, and build laboratory safety together.

Wonderful moments of laboratory safety month activities

1. How to properly wear personal protective equipment (PPE)

Professionals were invited to the scene to demonstrate to the teachers and students how to choose the correct protective clothing, how to correctly put on and take off the fireproof clothing to avoid secondary injuries and so on in the face of different accident emergency scenarios. In addition to theoretical explanations, on-site students and teachers were also invited to conduct on-site practical operations, and pointed out the matters needing attention in the process of wearing protective clothing.

Through the explanation of personal protective equipment, demonstration of daily experiments or response to emergencies, teachers and students have a clearer understanding of how to do personal safety protection work, ensure personal life safety, and improve laboratory safety.

2. Hazardous chemical leakage prevention and leakage accident emergency drill

Considering the disciplinary characteristics of the School of Materials Science and Engineering, there may be dangerous chemicals with strong corrosiveness (HF, nitric acid, sulfuric acid, etc.) in daily experiments. In the case of leakage of dangerous chemicals in the laboratory scene, let the teachers and students of the whole school deal with it proficiently. Emergencies are handled in a correct, orderly and efficient manner to ensure the safety of the lives of teachers and students throughout the school.

In the situational exercise, each teacher and student participating in the exercise has its own "role", some are laboratory safety leaders, laboratory personnel, some rescue personnel, medical personnel, security personnel, etc., different roles correspond to different Responsibilities and tasks, simulating laboratory nitric acid spills, how to properly respond and deal with them. The lecturer of SYSBEL invited two groups of on-site teachers and students to practice the process of leakage emergency disposal, and commented on the irregular actions that occurred during the disposal process, so as to deepen the understanding of teachers and students on the leakage emergency disposal process.

3. Laboratory emergency drill for flammable, toxic and explosive gas leakage

According to the characteristics of the School of Materials Science and Engineering, there may be flammable and toxic gases, flammable and explosive gases in daily experiments. This drill simulates a sudden gas leak in the laboratory and issues an alarm. The students in the drill correspond to different identities, evacuation, vigilance, rescue, first aid and other steps, so that the students at the scene can learn how to properly deal with toxic gas leaks.

Because of the toxic gas involved, how to choose the correct professional equipment such as protective clothing, protective masks, and air calls, and how to deal with people who are poisoned and comatose before 120, all lecturers and experts gave explanations and demonstrations, and let them feel Interested teachers and students personally try how to wear and first aid.

4. Laboratory electric shock emergency treatment drill

Teachers and students often use scientific instruments and equipment that need to be electrified (material testing machines, tensile machines, box-type resistance furnaces, electron microscopes, etc.) in daily experiments for electric shock accidents in laboratory scenarios, and electrical equipment is also prone to corrosion and line aging due to time. The reason is easy to cause electric shock and personal injury. In order to improve the ability and level of teachers and students to prevent electric shock accidents, ensure that rescue work can be carried out quickly and effectively in the event of an accident, test teachers and students' ability to coordinate and cooperate in emergency rescue, and effectively avoid or reduce casualties and property losses. Lecturer SYSBEL organized teachers and students to conduct emergency drills for electric shock.

5. Laboratory staff first aid professional practice drill

In the laboratory or daily work scenarios, the personal physical conditions of teachers and students are unexpected, such as heart disease, suffocation, epilepsy, external bleeding, internal bleeding, fractures or sprains, burns, poisoning, etc., how to deal with them correctly, and avoid using wrong first aid The method aggravates the injury of the injured person. For this reason, the professional training instructor of Maison Medical, the partner of SYSBEL, introduced professional rescue knowledge such as AED defibrillator and cardiopulmonary resuscitation to the teachers and students on the scene.

After watching the drill, Director of the Field Equipment Department, Mr. Yuan was deeply impressed and was very satisfied with the organization of this event. The combination of theory and practice made the students on site truly understand the importance of laboratory safety.
