Hygiene: Hands-free door opening is of course a major advantage in situations where infection can be spread by hands touching contaminated door handles and knobs. SafeOpen doesn't just protect against viruses, but also a host of other pathogens - whether they are bacterial, fungal or even parasitic.
Head and Body Clearance: SafeOpen is designed to allow users to approach the door from the side - staying clear of the opening swing of the door. This means that they are less likely to be caught unawares by the door opening suddenly. Contrast this with approaching face on and attempting to pull the door with one's foot. In this case, the user is within and opening swing of the door.
There are situations where this can't be helped, for example, an "Alcove Door" with a wall perpendicular to the opening edge. This prevents a user from approaching from the side. Even in this situation, the angled grip plate encourages the user to adjust their body and approach in a protective manner - rotating the hips and anchoring on the foot outside the opening circle.
Rotating the hips makes people stand side-on, thereby protecting their head Anchoring outside the opening circle naturally causes the body and head to lean in that direction too - any good cricketer will understand how the head and leading foot operate together! We'll upload some photos to show you - a picture paints a thousand words!
Foot and Ankle Clearance: SafeOpen is elevated above the bottom of the door, so that should the door open unexpectedly, there is little chance of impact on the foot. Indeed the risk of impact would be with the door, as if SafeOpen were not there at all. Even better, it is really difficult to bring any soft tissue into contact with SafeOpen, as a shoe will impact the underlying door before an ankle can get close. Nonetheless all angles have been softened with radii.
