About the basic parameters of safe evacuation, the number of evacuees in places with fixed seats should be calculated by 1.1 times, excluding cinemas and auditoriums.

evacuation number of basic parameters of safe evacuation: evacuation number = personnel density× building area

where the unit of personnel density is "person/m? Or m? /person ",the density of people in different places is as follows:

1) song and dance entertainment and entertainment venues

video hall: 1.1 person /m?

other song and dance entertainment venues: 1.5 people /m?

for song and dance entertainment venues, when calculating the number of evacuees, the construction area of auxiliary rooms such as evacuation walkways and toilets in the venue can be determined only according to the construction area of halls and rooms with entertainment functions in the venue, and the number of internal service and management personnel can be determined according to the approved number.

2) exhibition hall: 1.75 person /m?

3) places with fixed seats: 1.1 times the actual number of seats. (Note: Theaters, cinemas, auditoriums and gymnasiums are based on the actual seating capacity. )

Code for Fire Protection in Building Design

During the revision of this code, we followed the national guidelines and policies related to capital construction, implemented the fire protection policy of "putting prevention first and combining fire prevention with fire elimination", deeply learned the lessons from serious fire accidents in China in recent years, and earnestly summarized the practical experience and fire protection scientific and technological achievements of buildings at home and abroad;

In-depth research on the new situation, new problems and difficult problems encountered in the implementation of the code in the construction and development of the project, careful study and reference to the experience of developed countries, a large number of research projects, technical discussions and necessary experiments have been carried out, and opinions from relevant units such as design, production, construction, fire supervision, research and teaching have been widely solicited, and finally finalized through review. ?
