Evacuation of Bed-bound Patients-STEPS Simulations

摘要：

　　Fires in hospitals occur, and evacuation of bed-bound patients might be necessary in case of emergency.The current study concerns the evacuation of bed-bound patients from a fire section in a hospital using hospital porters.The simulations are performed using the STEPS program.The aim of the study is to investigate the evacuation time of bed-bound hospital patients using different walking speeds from the literature, and the influence of the number of hospital porters on the total evacuation times of bed-bound patients.Different scenarios were carried out with varying staff-to-patient ratios that simulate the horizontal evacuation of 40 bed-bound patients into a different fire section.It was found thatthe staff-to-patient-ratio affects the total evacuation times.However, the total evacuation times do not decrease linearly and a saturation effect is seen at a staff-to-patient ratio above 1 : 2.5.Simulations of evacuation of one bed-bound patient vertically, through a staircase 11 storeys high, were carried out using three different movement speeds from the literature.The simulations overestimated of the experimental results.The time difference is explained by a lack of detailed knowledge of evacuation procedure, resulting in a lack of input times for the simulations.Further studies on the procedure and subsequent times are needed.
