What is the minimum depth required for hinge approach on the push side of a door?

The minimum depth required for a hinge approach on the push side of a door is 42 inches. This standard is critical because it ensures that there is enough space for individuals using mobility devices, such as wheelchairs, to maneuver effectively around the door.

Having a 42-inch minimum depth allows for a sufficient clear area so that a user can approach the door at an angle, align themselves with the door, and use the door's hardware comfortably without obstruction. This dimension is based on accessibility guidelines, specifically within the framework of the Americans with Disabilities Act (ADA).

In practical terms, if the depth were any less, individuals might struggle to approach the door properly, leading to potential accessibility issues. Thus, the correct answer reflects the necessary compliance with established standards to promote safety and ease of access for all users.
