“…They also often assume that the green area will be in front of the outpatient entrance, in the outpatient department and the entrance hall, that the yellow area will be in the outpatient department and the entrance hall, that the red area will be in the emergency department, and that the black area will be near the morgue, the outpatient department, and the radiation department. 8 With reference to the above and considering that certain areas can be indicated in the architectural plans of the target hospital, we assumed that the treatment and recovery spaces for the green area correspond to the outpatient waiting area on the 2nd floor, the treatment space for the yellow area corresponds to the entrance hall (payment waiting area) on the 1st floor, the recovery space for the yellow area corresponds with the outpatient waiting area on the 2nd floor, the treatment and recovery spaces for the red area correspond to the emergency department, and the treatment space, when possible, and morgue space for the black area correspond to the radiation waiting area (Figure 2). 1 In the case of green-tag spaces, when the target hospital's useable outpatient waiting area of 543 m 2 , is multiplied by 70% (rental ratio) and the result is divided by 2 m 2 (minimum space necessary per person), it is revealed that 190 casualties can be accommodated in that space (note: in the outpatient waiting room 9 , the area per seat is 1.9 m 2 , so the figures quoted are rounded to the nearest whole number).…”
