What the subject wants to ask is "What are the problems in fire safety of Nanning subway?" Facilities and equipment are aging and crowded.

1, subway facilities and cable equipment are aging. In the operation of the existing subway, the aging of cable equipment is a major cause of subway fire, because most subway managers follow the technology of the traditional period and do not clearly realize the problems brought by the traditional model. Most managers do not often check cables and cannot fully understand the harm to cables.

2. The problem of crowded people. In the process of fire safety management, it is necessary to consider the congestion of pit stop, transfer and waiting, adjust the site area, ease the flow of people, ensure the smooth flow of fire exits and enhance the escape efficiency.
