Clear floor space dimensions on a handicapped accessible urinal shall be ________ by ________ inches.

The correct dimensions for clear floor space around a handicapped accessible urinal are 30 inches by 48 inches. This specification is designed to ensure that individuals with disabilities have adequate space to maneuver safely and comfortably. The 30-inch width allows for sufficient clearance for wheelchairs to approach and access the urinal, while the 48-inch depth provides enough room for positioning and support.

These dimensions are aligned with the requirements set forth in accessibility standards, which aim to foster inclusivity and usability in public restrooms. By establishing a clear floor space that accommodates a range of movement, regulations ensure that accessible facilities truly meet the needs of all users, thereby promoting independence and dignity.

Other options may reflect different dimensions that do not meet the standards necessary for accommodating individuals who may require extra space for mobility devices, therefore failing to provide the ideal environment for users needing accessible facilities.
