Turns around an Obstruction

A U-turn around an obstruction less than 48 inches (1220 mm) wide may be made if the passage width is a minimum of 42 inches (1065 mm) and the base of the U-turn space is a minimum of 48 inches (1220 mm) wide.

Overhead Hazards

Overhead Hazards. As an example, the diagram illustrates a stair whose underside descends across a pathway. Where the headroom is less than 80 inches, protection is offered by a railing (2030 mm) which can be no higher than 27 inches (685 mm) to ensure detectability.
