2.1.2.5. All doors, except as provided in paragraph .2.9, shall be provided with a combination mechanical lock and electric contact. Locking devices shall be protected against tampering from the landing side. The locking devices shall permit a door to be opened only if the platform floor is within 51 mm (2 inches) of the respective landing. The platform shall be permitted to move away from the landing under control of the normal operating device if the door is closed but not locked, provided that the device will cause the platform to stop if it moves more than 51 mm (2 inches) away from the landing before the door is locked.

B. ASME A18.1-2017 2.1.2 Partial runway enclosure provided, is amended by adding a new paragraph 2.1.2.9 to read as follows:

Where the lift is installed at a location that does not have guards at the upper landing as allowed by building codes (see definition), the requirements of paragraphs .2.2, .2.3, and .2.4 shall be permitted to be omitted when platform gates are provided. They shall extend to a height at least equal to the top terminal landing height plus 152 mm (6 inches) measured when the platform is at its lowest position. The gates shall be of unperforated construction, self-closing, and be provided with electric contact to prevent movement of the platform if the gates are not closed. The gates shall not be permanently deformed when a force of 556 N (125 lbf) is applied on any 102 mm (4 inches) by 102 mm (4 inches) area.

C. ASME A18.1-2017 2.1.2 Partial runway enclosure provided, is amended by adding a new paragraph 2.1.2.10 to read as follows:

2.1.2.10. The clearance between the platform floor and the upper landing sill shall be permitted to be increased to 76 mm (3 inches) if a platform gate complying with paragraph .2.9 and an automatically folding ramp to service the upper landing is provided. When deployed, the ramp shall have a minimum overlap at the upper landing sill of 51 mm (2 inches) and shall be substantially level. It shall be provided with an electric contact, which will stop the movement of the platform within 152 mm (6 inches) of travel away from the upper landing if the ramp has failed to rise to its retracted position.

D. ASME A18.1-2017 2.1.3 Runway enclosure not provided.

For purposes of A18.1-2017 section 2 Vertical platform lifts, 2.1.3 is deleted in its entirety. However, as referenced in A18.1-2017 section 5.1 Runways, 2.1.3 remains in full force and effect.
