(a) Landing openings shall be protected by doors of the horizontally swinging or sliding type. Grille or lattice-type construction shall not be used when fire-resistive hoistway enclosures are required.

(b) When swing-type doors are used the clearance between the hoistway enclosure door or gate and the hoistway edge of the landing sill shall not exceed two inches and the distance between the hoistway face of the landing door and the car door or gate shall not exceed four inches. When sliding-type doors with door closures are used the clearances specified may be increased to 2 1/4 inches and 5 1/2 inches respectively.

(c) The hoistway face of the landing door or gate shall not project into the hoistway beyond the landing sill. No hardware, except that required for door-operating devices, locks, contacts, or signals shall project into the hoistway beyond the line of the landing sill.

(d) Hoistway doors or gates shall be provided with locking devices and electric contacts conforming to the requirements of §§ 7.54 and 7.73 (relating to landing doors and locking devices; automatic control passenger elevators).

(e) No means shall be provided to open any landing door from the landing side when the car is not in the landing zone.

(f) Hoistway doors shall be so arranged that it will not be necessary to reach behind any panel, jamb, or sash to operate them.

(g) Means shall be provided to prevent hangers for sliding hoistway doors from jumping the track. Stops shall be provided to prevent the hanger carriage from leaving either end of the track, or suitable stops shall be provided on the door.
