座位数
Safety is a primary concern in determining the seating capacity of a venue: "Seating capacity, seating layouts and densities are largely dictated by legal requirements for the safe evacuation of the occupants in the event of fire". The International Building Code specifies, "In places of assembly, the seats shall be securely fastened to the floor" but provides exceptions if the total number of seats is fewer than 100, if there is a substantial amount of space available between seats or if the seats are at tables. It also delineates the number of available exits for interior balconies and galleries based on the seating capacity, and sets forth the number of required wheelchair spaces in a table derived from the seating capacity of the space.
