Building contractors may grumble about emergency lighting and safety regulations, but in an emergency the name of the game is egress. While local codes may vary somewhat in language, the International Building Code (IBC) states that "means of egress is a continuous and unobstructed path of vertical and horizontal egress travel from any occupied portion of a building or structure to a public way. A means of egress consists of three separate and distinct components: the exit access, the exit, and the exit discharge."
