Wheeling a hand truck, this 1996 image depicted a man departing a grocery store transporting a number of boxes to his vehicle. In order to pass out through the doorway safely, both his hands were needed to control the hand truck, therefore, had there have been a door with which to contend, it would have made negotiating the portal more complicated, and more difficult. Widely used, 'no-touch' automatic doors accommodate all types of users, including the mobility-challenged, as well as those whose hands are filled with purchases. Simple, and in common use, the wide automatic door is an excellent example of Universal Design. Other facilities should, where possible, consider this option.
