Abstract: With the gradual improvement of people's requirements for the quality of life, the consumer group of large shopping malls is increasing, which makes the density of personnel in some large commercial places increase, and also puts forward higher standards and requirements for the fire safety work of buildings and related places. Therefore, it is necessary to strengthen the fire supervision and management of large public places. At the same time, the reasons for the existence of fire safety hazards in large public places in China are not only the inadequate fire supervision and management, but also closely related to construction and fire fighting equipment. Therefore, based on the actual situation, this paper analyzes the hidden dangers of fire control and the key and difficult points of fire control supervision in public places, and puts forward relevant solutions and suggestions based on theoretical knowledge.
