USE OF DISTRESS SIGNALS (Cont)
SIGNALING BY DAY.
The official daylight signal is the Buoyant Orange Smoke Signal. These, however, have a very limited visibility range
especially in a stiff breeze.
Many tests have shown that in normal daylight conditions a hand flare or a rocket parachute signal can be seen at a
greater range than can an orange smoke signal. The ideal combination, therefore, is smoke and flare.
RADAR REFLECTIVE ROCKET SIGNALS
These signals, not widely used as yet, eject a cloud of radar reflective material which produces a distinctive echo on a
ship or aircraft radar for a period of 10 to 20 minutes and from a considerable range.
They can therefore be used both by day and night when it is considered that a search for survivors is in progress.
READ THE INSTRUCTIONS
Whatever the signals, always carefully read the Instructions affixed to them before attempting to fire them and follow
those instructions precisely.
FIRST AID
The following instructions are also included in the first aid kit with Illustrations of use on each package.
