NOTE: The FAA historically accepted the use of a red cross on a white background as being satisfactory for indicating first aid kits. The agency has been advised by the American Red Cross that the use of this symbol is limited by international and federal law, with the exception of certain pre-1905 users, military establishments and the American Red Cross. At this time the FAA does not have a recommended symbol for first aid kits.
768 Figure 1. NO SMOKING (DOT) Preferred version. Use wherever dimensional constraints permit. The circle-slash should be red, the cigarette and smoke black and the background white. The circle-slash should override the cigarette.
Figure 2. NO SMOKING Vertically challenged version - square "field" not applicable. If the sign is unlit, the cigarette may appear in positive form (dark gray) or negative (white). In the negative unlit version, provide sufficient background contrast for the red circle-slash. The negative form shown is recommended for a lighted sign. The circle-slash should be red and override the background or cigarette.
Figure 3. FIRE EXTINGUISHER (DOT) The fire extinguisher should be red and the background white.
Figure 4. FASTEN SEAT BELT For lighted sign use. Square "field" not applicable and may be cropped to fit a small vertical dimension. The arrow should be red, the seat belt white, and the background black or sufficiently contrasting to the red arrow.
769 Figure 5. NO CIGARETTE
DISPOSAL This symbol is intended for application to waste disposal openings.
The circle-slash should be red and override the cigarette and receptacle.
The cigarette smoke and receptacle should be black and the background white. Caution: Use of etch and fill media for reduced symbols should be avoided as metal necessarily exposed between colors diminishes symbol’s understanding.
Figure 6. RETURN TO SEAT To be used in lighted signage exclusively. The figure and seat may appear in either the positive form (dark gray) or negative form (lighted-white).
The arrow should be red.

777 APPENDIX 4
TEST PROCEDURES FOR EVALUATING NONSTANDARD EXITS
FOR TRANSPORT CATEGORY AIRPLANES
1. Where it is necessary to determine the acceptability of a non-standard exit arrangement for which an applicant has requested an exemption from the applicable 14 CFR, full scale testing should be employed using representative subjects under conditions such that accurate comparisons may be made.
2. PURPOSE OF THE TEST. The purpose of the test is to determine that the mean escape time using the proposed exit configuration is equal to or better than the time required to use an exit configuration defined by pertinent CFRS applying to Transport Category Airplanes. The results can be used to substantiate equivalency for an exemption or an equivalent level of safety determination. This test procedure should not be used for determining the rating of an exit or exit configuration, since it is not extensive enough for such a determination.
3. EXPERIMENTAL CONDITIONS.
a. Direct comparisons are to be made between escape time using the proposed exit or exits and corresponding acceptable arrangements. A proposed exit arrangement may be one or more openings not conforming in all respects to applicable CFR's which would, if approved, replace such opening or openings specified in the regulations.
b. A mockup of a section of the fuselage may be used such that arrangement of exit, passenger seats, step-up distance from cabin floor to exit sill and step-down distance from sill to wing or step simulate those proposed for the airplane. If high-density seating is to be used, the minimum distance between the seats should be simulated. Where over-the-wing exits are being tested and the step-down distances of two or more proposed exits differ, either the greater step-down distance should be used, or the several proposed exits should be simultaneously compared with the conventional arrangement they are designed to replace. In the case of floor level exits which are not located over the wing, or Type III and Type IV exits which are not located over the wing, or overwing exits which are at a greater distance than is specified in the CFR, the step, or descent device, shall simulate those designed for operational use and the device or conditions of use shall be fully described, including details of the dimensions. If production devices are available, they should be used.
c. At the start of each trial, subjects may either be seated with belts fastened or may be standing in line, whichever is more convenient, provided that the procedure is maintained consistently for each trial included in the test.
