Approved by OAL on March 13, 2000
Effective April 1, 2000
Amend Section 3089(d) to read:
Article 13. Escalators
§3089. Construction Requirements.
* * *
(d) Balustrades.
(1) A solid balustrade shall be provided on each side of the moving steps.
The balustrade on the step side shall have no areas or moldings depressed or raised more
than 1/4 inch from the parent surface, except when skirt deflection devices, such as
brushes, are used per Section 3089(d)(7). Such areas or moldings shall have all
boundary surfaces beveled unless parallel to the direction of travel.
(2) Safety glass or plastic panels, if used in balustrades, shall conform to the
requirements of ANSI Z97.1, except that there shall be no requirement for the panels to be
transparent.
EXCEPTION: Plastic material bonded to a basic supporting panel.
(3) The clearance on either side of the steps between the steps and the adjacent skirt guard shall be not more than 1/4 inch and the sum of the clearances on both sides shall be not more than 3/8 inch.
(4) The width between the balustrades in the direction of travel shall not be changed
abruptly nor by more than 8 percent of the greatest width.
In changing from the greater to the smaller width, the maximum allowable angle of change
in the balustrading shall be 15 degrees from the line of travel.
(5) A solid guard shall be provided in the intersecting angle of the outside balustrade
(deck board) and the ceiling or soffitt.
EXCEPTION: Where the intersection of the outside balustrade (deck board) and the ceiling
or soffitt is more than 24 inches from the center line of the handrail.
(A) The vertical face of the guard shall project at least 14 inches horizontally from the
apex of the angle. On existing installations the vertical face of the guard shall be not
less than 6 inches.
(B) The exposed edge of the guard shall be rounded to eliminate shear hazard. Guards may
be glass or plastic, provided they meet the requirements of Section 3089(d)(2).
(6) Existing escalators shall comply with the following:
(A) Skirt deflection devices to protect against the accidental entrapment of body parts,
clothing, shoes, etc., shall be installed; or
(B) Clearances between the skirt and the step shall comply with ASME A17.1-1996, Rule
802.3e, hereby incorporated by reference; and the skirt panel shall comply with ASME
A17.1-1996, Rule 802.3f, hereby incorporated by reference.
(C) The escalator shall be inspected by the Division, following the
completion of Section 3089(d)(6)(A) or (B), and a new permit to operate issued. Escalator
owners shall have three years from April 1, 2000 to comply with Section 3089(d)(6).
(7) If provided, the skirt deflection device shall comply with the following:
(A) The rigid portion of the device shall not rise more than 3/4 inch from the parent
surface of the balustrade;
(B) The plans, drawings, and specifications on the planned installation of the deflection
device shall be submitted to the Division for review before they are installed. The
Division shall review the plans, drawings, and specifications to ensure the planned
installations and subsequent operation does not conflict with other requirements of
Article 13;
(C) The deflection device shall be inspected by the Division for entanglement, entrapment,
shearing, or tripping hazard.

Amend Section 3091(k) to read:
Article 14. Moving Walks
§3091. Design Requirements.
* * *
(k) Balustrades. Moving walks shall be provided with an enclosed balustrade on each side conforming to the following:
(1) Construction.
(A) Balustrades without moving handrails shall be designed so as to provide no surfaces
which can be gripped by a passenger. On the treadway side, the balustrade shall have no
areas or moldings depressed or raised more than 1/4 inch from the parent surface,
except when skirt deflection devices, such as brushes, are used per Section 3091(k)(4).
Such areas or moldings shall have all boundary surfaces beveled unless parallel to the
direction of travel. The balustrades shall extend at normal height not less than 12 inches
beyond the end of the exposed treadway.
(B) Glass or plastic panels, if used in the balustrades, shall conform to the requirements
of ANSI Z917.1 except that there shall be no requirement for the panels to be transparent.
(C) Balustrades shall be designed to resist the simultaneous application of a lateral
force of 40 pounds per lineal foot and a vertical load of 50 pounds per lineal foot, both
applied to the top of the balustrade.
(2) The height of the balustrade shall be not less than 30 inches measured perpendicular to the treadway surface. At this height, the inner surface of the balustrade shall be located not more than 8 inches outside the vertical projected edge of the exposed treadway.
(3) If the balustrade covers the edge of the treadway, the clearance between the top surface of the treadway and the underside of the balustrade shall not exceed 1/4 inch. Where skirt panels are used, the horizontal clearance on either side of the treadway between the treadway and the adjacent skirt panel shall be not more than 1/4 inch.
(4) Where moving walks are provided with skirt deflection devices to
protect against accidental entrapment of body parts, clothing, shoes, etc., the following
shall apply:
(A) The rigid portion of the device shall not rise more than 3/4 inch from the parent
surface of the balustrade.
(B) The plans, drawings, and specifications on the planned installation of the deflection
device shall be submitted to the Division for review before the deflection
device is installed. The Division shall review the plans, drawings, and specifications to
ensure the planned installation and subsequent operation does not conflict with other
requirements of Article 14.
(C) The deflection device shall be inspected by the Division for
entanglement, entrapment, shearing, or tripping hazards.
