Step-by-step explanation:
The described continuous and unobstructed path of vertical and horizontal egress travel from any occupied portion of a building, structure, or premises to a public way is called an exit route. The exit route consists of three components: the exit access, which is the portion leading to an exit; the exit itself, which is the portion that provides a means of egress; and the exit discharge, which is the portion that leads from the exit to a public way. These exit routes are essential for the safety and evacuation of occupants during emergencies.
