EMERGENCY AND ADMINISTRATIVE
The flags and pennants (figs. 4-14 and 4-15)
represent only a few of the thousands of signals that can
be transmitted by flag hoist. Since they may be frequently
seen displayed aboard Navy ships or stations, it would be
to your advantage to learn to identify them and
understand their meaning. Your own personal safety may
someday depend on recognizing a particular signal flag.
Table 4-3 contains only those international signals
most commonly used and having the same meaning as
(International) I have a diver(s) down; keep well clear at slow speed.
