Usually, the evacuation is split into two main stages: pre-movement-phase and movement-phase. For both a large number of studies investigate different representations of behaviour and impacts. But the influence of impairments is usually not taken into account. In addition, most of the scientific researches focus the investigation of the movement phase. This publication presents a novel approach to score the need for assistance and to estimate the effect on evacuation performance. The proposed score considers characteristic impairments in three dimensions of behaviour: reception, perception and realisation. In an unannounced evacuation training in a sheltered workshop, the evacuation behaviour and pre-movement phase were analysed. The analysis indicates that the pre-movement time depends on the kind of impairment as well as on organisational boundaries. Despite the special needs for assistance, the evacuation process in a sheltered workshop is quite similar to other sub-populations. T2 - 5.
