2.14.1 Passenger and Freight Enclosures, General
(a) not be unfastened from inside the car by the use of common tools
(b) be permitted to be removed from inside the car when perforations, exceeding that which would reject a ball 13 mm (0.5 in.] in diameter, in the enclosure used for panel hanging or support have permanent means to prevent straight-through passage beyond the running clearance
The enclosure walls shall be designed and installed to withstand a force of 330 N (75 lbf) applied horizontally at any point on the walls of the enclosure without permanent deformation and so that the deflection will not reduce the running clearance below the minimum specified in 2.5.1, nor cause the deflection to exceed 25 mm (1 in.).
Where one compartment is intended for freight use, its minimum rated load shall conform to 2.16.1 or shall be based on the freight loads to be handled, if greater than the minimum rated load required by 2.16.1.
Where both compartments are used exclusively for freight, the minimum rated load of each compartment shall conform to 2.16.2.
The rated load of the elevator shall be the sum of the rated loads of the individual compartments.
(a) The top emergency exit opening shall have an area of not less than 0.26 m2 (400 in.2) and shall measure not less than 400 mm (16 in.) on any side.
(b) The top emergency exit and suspended ceiling opening, if any, shall be located to provide a clear passageway, unobstructed by fixed equipment located in or on top of the car. Equipment is permitted directly above the exit opening, provided that
(1) it is not less than 1070 mm (42 in.) above the top of the car
(2) the exit is located to allow unobstructed passage of a parallelepiped volume measuring 300 mm x 500 mm x 1500 mm (12 in. x 20 in. x 59 in.) at an angle not less than 60 deg from the horizontal (see Nonmandatory Appendix C)
(c) The top emergency exit cover shall open outward. It shall be hinged or securely attached with a chain when in both the open and closed positions. If a chain is used, it shall be not more than 300 mm (12 in.) in length and shall have a factor of safety not less than 5. The exit cover shall be openable from the top of the car without the use of special tools and shall be permitted to be openable from within the car by means of a keyed spring-return cylinder-type lock having not less than a five-pin or five-disk combination. This key shall be Group 1 Security (see Section 8.1). The exit cover of the lower compartment of a multideck elevator shall be openable from both compartments. On elevators with two compartments, if the emergency exit of the lower compartment does not open directly into the upper compartment, a guarded passageway shall be provided between the lower compartment roof and the upper compartment floor.
(d) The movable portion (exit panel) of the suspended ceiling that is below the top exit opening shall be restrained from falling. It shall be permitted to be hinged upward or downward, provided that the exit permits a clear opening with the top exit opening.
(1) A minimum clear headroom of 2030 mm (80 in.) above the car floor shall be maintained when downward-swinging suspended ceiling exit panels are used.
(2) Upward-opening suspended ceiling exit panels shall be restrained from closing when in use and shall not diminish the clear opening area of the corresponding top exit opening.
(3) The movable portion and the fixed portion of a suspended ceiling shall not contain lamps that could be shattered by a rescue operation using the top emergency exit. The movable portion of the suspended ceiling shall be permitted to contain light fixtures connected to the stationary portion of the suspended ceiling wiring by means of a plug and socket or by flexible armored wiring. Flexible wiring shall not be used to support or restrain the exit opening in the suspended ceiling in the open position.
(e) Where elevators installed in enclosed hoistways are provided with special car top treatments such as domed or shrouded canopies, the exit shall be made accessible, including the car top space specified in (f).
(f) Immediately adjacent to the top emergency exit there shall be a space available for standing when the emergency exit cover is open. This space shall be permitted to include a portion of the area required in 184.108.40.206.2. All exit covers shall be provided with a car top emergency exit electrical device (see 220.127.116.11) that will prevent operation of the elevator car if the exit cover is open more than 50 mm (2 in.), and the device shall be designed so that it
(1) is positively opened
(2) cannot be closed accidentally when the cover is removed
(3) must be manually reset from the top of the car and only after the cover is within 50 mm (2 in.) of the fully closed position
(4) shall be protected against mechanical damage
(a) when the car has reached its maximum upward movement (18.104.22.168)
(1) 100 mm (4 in.) vertically
(2) 300 mm (12 in.) horizontally toward the center-line of the car enclosure top
(b) throughout the hoistway, 100 mm (4 in.) horizontally in the direction toward the hoistway enclosure
NOTE (22.214.171.124.2): See Nonmandatory Appendix G.
(a) be constructed of laminated glass that complies with the requirements of 16 CFR Part 1201, Sections 1201.1 and 1201.2; or be constructed of laminated glass, safety glass, or safety plastic that complies with CAN/CGSB-12.1, CAN/CGSB-12.11, or CAN/CGSB-12.12, whichever is applicable (see Part 9)
(b) be provided with a handrail or framing designed to guard the opening should the panel become detached, where wall panels are wider than 300 mm (12 in.)
(a) it conforms to ANSI Z97.1; 16 CFR Part 1201, Sections 1201.1 and 1201.2; or CAN/CGSB-12.1, whichever is applicable (see Part 9)
(b) the glass is not subjected to further treatment such as sandblasting, etching, heat treatment, or painting that could alter the original properties of the glass
(c) the glass is bonded to a nonpolymeric coating, sheeting, or film backing having a physical integrity to hold the fragments when the glass breaks
(d) the glass is tested and conforms to the acceptance criteria for laminated glass as specified in ANSI Z97.1; or 16 CFR Part 1201, Section 1201.4; or CAN/CGSB-12.11, whichever is applicable (see Part 9)
