Entrances, doors and gates: approach clearances

Chapter 4: Accessible Routes Entrances, Doors, and Gates Recommendation: Wheelchair space 30” min. by 48” min. beyond the swing of a door in other configurations, such as vestibules with doors on adjacent walls, will provide room to clear one door before opening the next. Door and Gate Hardware [§404.2.7] Door and gate hardware must:  allow one-hand operation  not require tight grasping, pinching, or twisting of the wrist  operate with 5 lbf maximum  be located 34” to 48” above the floor or ground. Hardware that can be operated with a loose grip or closed fist, such as lever-shaped handles and U-shaped pulls, accommodates the greatest range of users. (Closed-fist operation, while advisable, is not mandated by the Standards). Round door knobs do not comply because they require twisting of the wrist. Latches and locks with small parts that must be manipulated can be difficult to use and will not comply if pinching is necessary. However, keys and access cards that are not part of the lockset are not required to comply (but those that do not require pinching or turning provide better access). Hardware that does not require simultaneous actions are better, but some types, such as handles with thumb latches are acceptable. Recommendations:  Specify hardware that is usable with a closed fist of loose grip  Bars, pulls, and similar hardware should provide sufficient knuckle clearance (1½” minimum) to facilitate gripping  Avoid hardware that requires hand or finger dexterity, fine motor movement, or simultaneous actions. 10
