Objectives: Through the reflection on the city’s response to the crisis in the process of tobacco control, a comprehensive and systematic public safety prevention and control system will be built to help cities cope with future risks and challenges. Methods: By using the methodological
principle of the unity of subject and object and systematic research, this paper analyzes the problems from the three aspects of subject, object and means, and puts forward three important links of prevention, response and guarantee to construct a large urban public security system, and these
three links support each other form a closed loop of risk prevention and control urban public security. Results: Under the background of tobacco control, it is feasible to a reliable whole-cycle management system for urban emergency response and accident rescue, a sound basic public safety
guarantee system and a whole-society participation system. Conclusions: Due to the change of global climate conditions and the increase of flow people in the social environment, human beings will face a more complex living environment in the future and may encounter more extreme problems.
It can be said that at present and even in the future, global urban public security risk management work is facing a grim situation. WHO research shows that smoking will increase the risk of new crown virus infection among smokers and their surrounding population.China is a big smoking country
and in the stage of rapid urbanization. Many citiesare densely populated. Once there is an epidemic infection, the cities will face a severe public security situation. Smoking will not only have an adverse impact on personal health, but also the fires in factories, homes and forests caused
by smoking.Since the Chinese government’s tobacco control in 2014, various accidents caused by smoking have caused great adverse effects.Smoking in public places has great hidden dangers of public safety, which leads us to think about the risk management of urban public safety.In the
context of tobacco control, we should use scientific thinking and methods to construct a new pattern of urban public security risk management. Another important concept is to implement the risk management concept and the value of prevention first in the management of public affairs, so as
to create a situation of risk sharing and coordinated response of the whole society.
