in chapter 5, the OSCAR should always be made upfor the break). When a person is lost over the side atnight, the peacetime procedure is to display twoflashing red lights arranged vertically. These two redlights, visible 2 miles all around the horizon, are thenot-under-command lights. They are pulsated 50 to 60times a minute by means of a crank on the light panelin the pilothouse.In addition to the two red lights, the ship losingthe person sounds, either by day or night, at least sixshort blasts on the ship's whistle and/or fires one whitestar.Another surface ship emergency is emergencybreakaway, which is covered later in this chapter.SIGNALMAN AS A MEMBER OF THEBOATCREWLEARNING OBJECTIVES: List and explainthe duties of the boatcrew Signalman, includingday and night movements, the use of the Mk135 pyrotechnic signaling kit, and safetyprecautions for using the pyrotechnic kit.One of the most important single billets you canfill in your naval career is that of boat Signalman. Youwill be on your own; you won't have any otherSignalmen on whom to rely. The success of aparticular mission depends on your ability to send andreceive communications, both by visual means and byvoice radio. Your ability to recognize and interpretsignals will have a direct bearing on the success of thatmission.The normal boatcrew allowance does not includea Signalman; however, there will be one assignedwhenever the boat is used for distress or emergencypurposes.In the event of a man overboard, a downed aircraft,or other cases where personnel are to be rescued, aSignalman is assigned to the boat. In a small boat, therange of visibility is very limited, because of the lowheight of eye. For this reason, other personnel areassigned to stations high in the ship to keep the personin sight. The ship can then direct the lifeboat to thevicinity of the person in the water by means offlaghoist, semaphore, flashing light, pyrotechnics, orvoice radio. It is your job to receive these directionsand pass them on to the boat officer and coxswain.The emergencies that arise at sea that require aboat Signalman are many. So that you will not befound wanting in one of these emergencies, you mustbe familiar with all phases of visual communicationsand proper voice radio procedures.DIRECTING THE BOAT BYVISUAL SIGNALSMost boat signals are made by pyrotechnics(signal flares fired by the Mk 135 signal kit),multipurpose lights, semaphore, and flaghoist.Vari-Color Illumination Signal KitThe Vari-color Illumination kit (fig. 8-4) or Mk135 is a small, lightweight unit used primarily fordistress signaling. A complete kit consists of aprojector and a plastic bandoleer containing three redsignals, two white signals, and two green signals. Aninstruction sheet is included with each kit. Othercombinations of signals and projectors are alsoavailable. When fired from the projector into the air,the flare burns for a minumum of 4.5 seconds at aaltitude of no less than 250 feet. The signal in thesekits produces a single red, green, or white star.OperationTo operate the Mk 135, first cock the firing pin ofthe projector by moving the trigger screw to thebottom of the vertical slot and slipping it to the rightso that it catches at the top of the safety slot. Bend theprotective tab away from a signal in the bandoleer toallow removal of the signal flare. Signalmen must befamiliar with the arrangement of colors in thebandoleer in the case of night operations to preventfiring of the incorrect color signal. A good practicewould be to arrange the signals in the bandoleer withthe green signals to starboard (right), the red to port(left), and the white in the middle.CAUTIONThe projector must not be loaded untilimmediately before firing. If after loading asignal it is not used, it must be removed andreturned to the bandoleer.After locating the correct color signal, mate theprojector with the signal. Hold the projector over thehead with the arm fully extended. The projector should8-12
Figure 8-4.-Vari-color signal illumination kit (Mk 135).be pointed at a slight angle to the body. While firmlygripping the projector, fire the signal by slipping thetrigger screw to the left out of the safety slot and intothe firing slot. If the signal fails to fire, try again bydepressing the trigger screw to the bottom of the firingslot with the thumb and releasing it quickly. Unscrewthe spent signal case or a signal that has failed to fire.Discard by throwing it overboard.8-13
