SYMBOLIC REGULATORY MESSAGES

1. Figure 1. No Smoking (DOT) *

2. Figure 2. No Smoking (vertically challenged) *

3. Figure 3. Fire Extinguisher

4. Figure 4. Fasten Seat Belt

5. Figure 5. No Cigarette Disposal *

6. Figure 6. Return to Seat

7. Figure 7. No Stowage

8. Figure 8. Life Raft

9. Figure 9. Oxygen

10. Figure 10. Megaphone *Amendment 25-51, effective March 6, 1980, and AIRWORTHINESS DIRECTIVE (AD) 74-08-09, effective April 8, 1974, requires words for Lavatories.

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.

770 Figure 7. NO STOWAGE The circle-slash should be red and override the suitcase. The suitcase should be black and the background white.

Figure 8. LIFE RAFT The life raft should be red, the person and wave black.

Figure 9. OXYGEN The bottle and printing should be green and the background white.
