(1) Hoistway doors shall be not less than 6 feet 6 inches high.

(2) Hoistway doors and gates including their components, such as guides, guide shoes, tracks, locking devices, hangers, hinges, etc., shall be so designed, constructed, installed and maintained that the fully closed door or gate shall not deflect beyond the centerline of the car-to-landing sill clearance when subjected to a force of 75 pounds applied perpendicular to the door or gate and distributed over an area of 1 square foot on any part of the door or gate, including the components.

(3) When subjected to a force of 250 pounds applied as described in subsection (a)(2), doors or gates and their components shall not be displaced from their supports, guides, tracks, hinges, latches and locking devices, or be permanently deformed or otherwise made inoperative.

(4) Where multi-section doors or gates are used, each panel shall withstand the forces specified in subsections (a)(2) and (a)(3).

(5) Solid doors, where used, shall be provided with a vision-panel or panels having an opening width of not more than 6 inches, and an area not more than 80 square inches per panel covered with expanded metal or wire mesh which shall reject a 3/4-inch ball or clear material having equivalent strength. The vision panel shall withstand a force of 75 pounds applied perpendicularly to any part of the panel and distributed over an area of 1 square foot with no greater deflection than any other part of the door as allowed in subsection (a)(2).

(b) Door Locking Devices.

Landing doors shall be provided with a means that will lock the doors mechanically so that they cannot be opened from the landing side.

These locks shall, at the landings other than the lowest landing, be of a type that can be released only by a person in the car.

If the door at the lowest terminal landing is locked automatically when closed with the car at the landing, it shall be provided with means to unlock it from the landing side to permit access to the car. The means provided shall be accessible only to authorized persons. A hook and eye shall be prohibited as a door locking device.
