Abstract:

In order to formulate safety management countermeasures and optimize laboratory safety training for hazardous chemical laboratories in universities, taking the explosion accident of a dangerous chemical laboratory in a university as an example, 24Model of behavior safety was used to to study the direct cause deeply, indirect cause, root cause and the root cause of the accident from the individual level and the organization level. Then the accident behavior analysis model of the dangerous chemical laboratory was established. The model provided specific requirements for the daily supervision and inspection of the laboratory, the construction of the laboratory risk control system and the construction of the laboratory accident emergency response system. Based on this model, the current domestic laboratory teaching models were investigated, and the safety education and training system of hazardous chemical laboratories in colleges and universities was constructed. The results hold that the model analysis security 24Model is generally applicable to the cause of the accident analysis. Analyzing accidents in laboratories in colleges and universities by the model, putting forward suggestions for improvement from the individual level and organizational level, can improve college for laboratory safety management, improve the students' consciousness of security risks, fundamentally to prevent accidents.
