indicate the fire evacuation plan of a certain place and area, make drawing marks, draw directions, such as what represents what, indicate the layout of fire-fighting equipment, facilities, regional articles, etc., and most importantly, indicate the fire exits and evacuation routes, and post them in obvious positions.

The design standard is based on the Code for Fire Protection Design of Buildings. The most basic thing is to have drawings of each floor or factory building, which can clearly see the indoor and outdoor layout, people gathering places and so on. It is necessary to indicate the specific entrances and exits, indicate the safety indicator lights, and also indicate the specific placement positions of fire extinguishers and fire hydrants.

in order to ensure safe evacuation from dangerous areas, buildings should be equipped with necessary evacuation facilities, such as fire exits, evacuation stairs, overpasses, escape holes and evacuation protection areas. The evacuation plan should be made in advance, and the evacuation plan and evacuation route should be studied, such as doors, walkways and stairs. Determine the time and distance from a certain point in the building to the safety exit. For example, the straight-line distance from any point in the hall to the nearest evacuation exit of a shopping mall should not exceed 21 meters.

calculate the evacuation flow and the evacuation time for all personnel to evacuate from the dangerous area, so as to ensure the traffic capacity of walkways and stairs. For example, the total width of stairs should be calculated according to the number of people passing through 111, and the minimum clear width should be specified. For example, the width of evacuation stairs in hospitals should be not less than 1.3m, and that of houses should be 1.1m. Audio-visual signals must be set to instruct people to evacuate and leave the dangerous area.
