granted by the officer of the deck in port or thecommanding officer when under way. Guidance forrequesting permission should be included in the signalbridge standing orders.OPNAVINST 5100.19, Navy Occupational Safetyand Health (NAVOSH) Program Manual, containsinstructions and general precautions for going aloft.MAINTENANCE AND MATERIALMANAGEMENT (3-M) SYSTEMLEARNING OBJECTIVE: Explain the purposeof the 3-M system, the Hazardous MaterialUsers Guide and material safety data sheets(MSDS).Although this chapter points out that Electrician'sMates generally are responsible for electrical repairsof signal equipment, signal bridge personnel doperform routine upkeep and maintenance functions onassigned equipment. Periodic checks and adjustmentsmust be made, for example, and there are stipulatedtimes when equipment should be lubricated for bestperformance.To achieve maximum efficiency in the use ofmaterial, as well as manpower, the Navy implementedthe 3-M system. The basic purpose of the systems isto provide for managing maintenance andmaintenance support in a manner that will ensuremaximum equipment operational readiness. The 3-Msystem standardizes preventive maintenancerequirements, procedures, and reports on a fleetwidebasis.OPNAVNST 4790.4, Maintenance and MaterialManagement (3-M) Manual, is the basic source ofinformation on the 3-M system.HAZARDOUS MATERIALUSERS GUIDEThe Hazardous Material Users Guide wasdeveloped to provide Navy personnel, particularly thedeckplate sailor, with safety data for hazardousmaterials commonly used on ships. The Users Guideis written to avoid the need for technical jargon,chemical symbols, or coded information frequentlyfound in material safety data sheets (MSDS).The Users Guide gives control measures, safetyprecautions, health hazards, and spill control anddisposal guidelines for each of 20 hazardous materialgroups (for instance, adhesives, cleaners, greases,paints, and solvents).The Control Measures section identifies andprescribes personal protective equipment (PPE)that is appropriate for the chemical hazards in aparticular group.The Safety Precautions section gives safetyguidance for using and storing hazardousmaterials in the group.The Health Hazards section points out commonsigns and effects of overexposure to thehazardous materials and provides “‘what to do”instructions to the hazardous materials user.The Spill Control section provides informationfor responding to a spill.The Disposal Guidelines section givesacceptable methods for disposing of materialswithin the group.Materials not included in the Users Guide areitems such as ammunition, explosives, propellants,medical/pharmaceutical supplies, and radioactivematerials.Material Safety Data SheetsMSDSs are technical bulletins containinginformation about materials, such as composition,chemical and physical characteristics, health andsafety hazards, and precautions for safe handling anduse. MSDSs should be readily available for every itemof hazardous material aboard ship.When performing maintenance and working withhazardous materials, use of the Users Guide andMSDSs is mandatory. Guidelines contained thereinare vitally important and MUST NOT be ignored. Theinformation will help reduce the risk of injury andlong-term health effects.SUMMARYIn this chapter you were informed of some of theequipment you will come in contact with during yourdaily routine aboard the signal bridge. This equipmentranges from the 12-inch searchlight to the Mk 37 NVS.You were informed how to operate and maintain thisequipment. You were also informed about the care andmaintenance of flags, pennants, and halyard line. Asyou know by now, knowing how to operate signalbridge equipment is a valuable part of being a<strong>Signalman</strong>. Learn your equipment well!2-28
CHAPTER 3MESSAGESA message can be defined simply as acommunication sent from one person to another. TheNavy defines a message as "Any thought or idea brieflyexpressed in plain or cryptic language, prepared in aform suitable for transmission by established means ofrapid communication." The visual message, with whichyou are most concerned, is prepared for transmission bymeans of flashing light, flaghoist, or semaphore.Incidentally, a message that contains the names of signalflags in its text, regardless of the method by which it istransmitted, is a signal.ORIGINATING MESSAGESLEARNING OBJECTIVES: Explain theprocedure for originating, drafting, andreleasing messages. List the types of messagestransmitted by communications means.ORIGINATORThe originator of a message is the authority inwhose name a message is sent, or agency under directcontrol of the authority approving a message fortransmission. The originator is responsible for thefunction of the drafter and releasing officer. Otherresponsibilities of the originator include determiningwhether the message is necessary (a message is not tobe used when a letter or other form of communicationwill suffice), determining the addressees and type ofmessage, and determining the security classificationand precedence. The originator must make sure thatthe prescribed message form is properly used, that thetext is drafted according to procedure, and that themessage is signed by the releasing officer. Theoriginator is also responsible for forwarding themessage to the appropriate agency for transmission.DRAFTERThe drafter is a person who actually composes amessage for release.RELEASING OFFICERThe releasing officer is a person who authorizesthe transmission of a message for and in the name ofthe originator.TYPES OF MESSAGESThe types of messages transmitted by communicationmeans are the following:Single addressMultiple addressBookGeneralSingle AddressA single-address message is one destined for onlyone addressee.Multiple AddressA multiple-address message is one that is destinedfor two or more addressees, each of whom must beinformed of the other addressees. Each addressee mustbe indicated as ACTION or INFORMATION. Thenumber of multiple-address messages must bereduced to the essential minimum, since processingthem is one of the major factors contributing to delayin message handling. In addition, originators shouldalways consider specifically whether all addresseesmust be informed of the other addressees of eachmessage, and if not, a BOOK message should be used.BookA book message is one that is destined for two ormore addressees and is of such a nature that theoriginator considers that no addressee need beinformed of any other addressee. Each addressee mustbe indicated as action or information.GeneralGeneral messages are messages that have a widestandard distribution. They are assigned an identifyingtitle and usually a sequential serial number; example,ALCONCEN 50.Book and general messages are normally receivedby radio.3-l
