2. Emergency exit panels.
(1) The enclosure shall be securely fastened to the car platform and so supported that it cannot loosen or become displaced in ordinary service or on application of the car safety or on buffer engagement.
(2) The enclosure walls shall be of such strength and be so designed and supported that when subjected to a pressure of 75 pounds applied horizontally at any point on the walls of the enclosure, the deflection will not reduce the running clearance below the allowed minimum.
(3) No elevator car shall have more than one compartment. Two compartments in the same horizontal plane will be permitted, provided that access to the landings can be had through only one of them.
EXCEPTIONS: Passenger elevators or freight elevators may have two compartments, one of which is located immediately above the other provided the compartmented elevator conforms to the following requirements:
1. The elevator shall be used exclusively for passengers or exclusively for freight at any one time.
2. Each compartment shall conform to the requirements of this Section except that a trap door in the floor of the upper compartment shall provide access to the top emergency exit for the lower compartment.
3. Where either or both compartments are intended for passenger service, the minimum rated load for each compartment shall conform to the requirements of Section 3037(a).
Where one compartment is intended for freight use, its minimum rated load shall conform to the requirements of Section 3037(a) or shall be based on the freight loads to be handled, if greater than the minimum rated load required by Section 3037(a).
Where both compartments are used exclusively for freight, the minimum rated load of each compartment shall conform to the requirements of Section 3037(a).
The rated load of the elevator shall be the sum of the rated loads of the individual compartments.

The composition will be two lites of minimum 1/4-inch glass with a tolerance of + 1/32-inch. The inner lite may be heat treated or plate glass. The outer lite may be tinted, or reflective, but shall not have a rated strength and impact resistance less than 1/4-inch plate glass. Heat treated glass may be annealed, heat strengthened or fully tempered.
Joining or laminating the two glass lites together shall be an interlayer of polyvinyl butyral not less than .060 inches thick.

(F) These are minimum standards for glass and glazing in elevators. For unusual designs or other applications, it is suggested that a responsible professional engineer be consulted. The technical representative of glass suppliers may be consulted regarding size availability and glazing details. Maximum glass area, per lite, shall be reviewed in each application with reference to applicable codes or building authority requirements.
