Physical Access: Issue 2 of 2

Issue: Sufficient clear floor or ground space is not provided.

If sufficient clear floor or ground space is not provided in front of a kiosk, users in wheelchairs may have difficulty positioning themselves in a location from which they can interact with the machine. In some situations, users may need to turn around in order to depart from the machine after completing a transaction, and sufficient space must also be provided to allow users in wheelchairs to turn around.

Populations Impacted: Users with lower mobility impairments.

Potential Solutions:
  • Provide a minimum clear floor space of 30" by 48" in front of the device. The minimum space required for a single stationary wheelchair and its occupant is 30" by 48", so a clear space of at least that size should be provided either parallel or perpendicular to the machine. Ideally, a 48" by 48" clear space should be provided, to accommodate both forward approach and parallel approach to the machine. The slope of the clear space should not exceed 1:48.

  • If applicable, provide sufficient clear space for a wheelchair to turn around in front of the device. If a kiosk is installed in a location where users in wheelchairs will need to turn around after using the machine (for example, a machine located against a wall, where users would approach the machine from the front and then turn around and depart), a circular or T-shaped turning space should be provided in front of the machine. A circular turning space should be a minimum of 60" in diameter. A T-shaped turning space should be within a 60" square minimum, with the arms and base 36" wide minimum as shown in the figure below.

  • ADA-ABA image showing a T-shaped turning space.  The arms and base of the T are each 36 inches wide, within a 60 inch by 60 inch square.
  • Provide an appropriate floor or ground surface in front of the device. The floor or ground surface should be stable, firm, and slip resistant. Carpet should be securely attached, with a firm pad or no pad. The pile height of carpet should not exceed ". Openings in the floor or ground surface should not allow passage of a sphere more than " in diameter, and elongated openings should be placed so that the long dimension is perpendicular to the dominant direction of travel.
