When training new hires, a large retail store asks employees to study the evacuation map posted at both of the store’s main exits. Pierre has low vision, and during his orientation his manager realizes that Pierre will need help to understand the map. He explains the map in detail and walks Pierre through the escape route until he feels comfortable with it. Pierre says that he is worried about obstacles, like clothing racks, that get moved around and that he might bump into. So his manager decides to establish a “buddy system” for emergencies.
