vegetable oil. Upon contact with the burningsurface, APC generates a soap-like froth thatcontains steam, which causes CO2 and glycerinebubbles to float on top of the burning oil. Thebubbles exclude air from the surface of the greaseor oil, which extinguishes the fire.Egress ProceduresEscape routes from below-deck spaces toweather decks should be clearly marked withdirectional arrows and appropriate labeling.Phosphorescent markings and appropriate emer-gency lighting of egress routes, hatches, andladders will ensure that personnel will be able tosafely find their way topside in the event of a lossof ship’s power.The emergency escape breathing device (EEBD)provides personnel with respiratory and eyeprotection in an atmosphere that will not supportlife.All personnel must learn to follow escaperoutes to weather decks by taking part in blind-fold drills. Additionally personnel should betrained on the location and the proper wearingof EEBDs. The method of and frequency requiredfor egress training are contained in type com-mander directives.CBR DefenseCBR defense means defense against chemicalor biological agents used in attacks or defenseagainst radiation from nuclear explosions.Personnel must be able to detect and identifycontamination, to decide on the protectivemeasures needed, and to decontaminate shipsurfaces, equipment, and personnel.In studying CBR defense, remember thatweapons are always developed and new defensemeasures are being established to deal with them.You will need to keep up to date with thesechanges.The ship’s bills that apply to shipboard CBRdefense include the general emergency bill; theCBR defense bill; and the ship’s battle bill. Allpersonnel must be indoctrinated and trained tocarry out the duties described in these bills. Forinformation on the ship’s battle bill and foradditional information on other bills, seeStandard Organization and Regulations of theU.S. Navy, OPNAVINST 3120.32.Personnel under CBR attack should be pro-tected through individual and group measures.Individual protection is of immediate concern.What you do in the first few moments after a CBRattack may determine whether or not you survive.Know the symptoms of exposure to radiation andto biological and chemical agents. Know theaction to take when you are exposed and any self-aid and first-aid measures that might help you oryour shipmates. This knowledge may mean thedifference between life and death.COMPARTMENT CHECKOFF LISTSCompartment checkoff lists (fig. 7-5) providean itemized listing of all classified fittingsand closures used in damage control to set thespecified material condition of readiness. They areoriginally prepared and furnished by the shipbuilder’s design agent during the construction ofa ship or class of ships. It is each ship’s respon-sibility to keep the lists current. Follow theguidelines listed in the Naval Ships’ TechnicalManual, chapter 079, volume 2, when you checkand update your compartment checkoff lists.All compartments must have a compartmentcheckoff list permanently posted within them inclear view of the space access. Weather decks thathave damage control facilities must also have acompartment checkoff list posted. The compart-ment name and number are entered on the listalong with all classified fittings and certain otherdamage control facilities in the compartment thatare necessary to help damage control personnelin the performance of their duties. The informa-tion listed for each of the classified fittings andother facilities on a compartment checkoff listincludes the following:• Name of item• Number of item• Location of item• Purpose of item• Classification of item (if classified)• Division responsibility for the properoperation of each fittingWhen a compartment has more than oneentrance, duplicate compartment checkoff listsmust be posted at each entrance. The compart-ment checkoff lists shall be clearly labeledDUPLICATE. Partial compartment checkoff listsmay be desirable when a compartment contains7-14
