Many ships, such as carriers, tankers, andtugs, have independent diesel-driven fire pumps.If ship’s pumps and firemain are damaged, thesediesel-driven pumps can be used to furnish largeamounts of water for firefighting purposes.LIGHTING SYSTEMOn ships using a.c. generators, the ship’s serv-ice and emergency lighting systems are energizedfrom the generator and distribution switchboardsthrough a bank of transformers. Thesetransformers supply power to the lighting systemthrough the lighting distribution panels.Lighting throughout the machinery spaces issupplied from the normal switchboard for thecompartments involved, with some lights in eachspace supplied from the alternate switchboard. Afew lights in each compartment are suppliedthrough automatic bus transfer equipment fromcircuits originating at the emergency switch-boards. A few lights in each compartment are sup-plied through automatic bus transfer equipmentfrom circuits originating at the emergencyswitchboards.Automatic type hand lanterns are provided tosupply an instantaneous source of illumination,in the event of complete failure of the ship’s serv-ice and emergency lighting systems. These relay-operated hand lanterns are installed at vitalstations. In addition to these, nonautomatic typehand lanterns are also installed at these stations.An EN1 or ENC in charge of an engineeringspace has the supervisory responsibility to see thatthe hand lanterns, especially the automatic type,are not removed except for actual intended use,and that hand lanterns are available for use at alltimes. Although the Electrician’s Mates have theresponsibility for the maintenance of the handbattle lanterns, it is the duty of the petty officerin charge of the space to see that personnel donot remove the lanterns or use them forunauthorized purposes.The EN1 or ENC should also ensure that per-sonnel have an adequate number or flashlightsavailable for use should all the lights in anengineering space go out.ELECTRICAL POWER PANELSAND TERMINALSPower panels are supplied with two or threesources of power—normal, alternate, andemergency. These panels are equipped with cir-cuit breakers or switches which permit the transferfrom one source to another in the event of acasualty.Regular electrical outlets are installedthroughout the engineering spaces for use withsmall portable tools; multipurpose outlets are in-stalled in selected locations for use with portablesubmersible pumps and portable welding sets.These outlets are located so that it is possible touse two portable submersible pumps in any water-tight compartment. Portable triple outlet ex-tension cables are provided to permit theconcentration of all submersible pumps in onearea. An adapter provided with these extensioncables permits connection of the submersiblepumps to the casualty power terminals. All thisequipment is stowed in the damage controllockers.Engineroom personnel should be trained in theemergency use and operation of submersiblepumps as well as other damage control equipment.They should know the location of both normaland emergency power outlets in their spaces, andshould understand the different methods used tosupply electrical power for operating submers-ible pumps in the engineroom.Engineroom personnel should also be familiarwith sources of electrical power provided to thedifferent power panels in an engineroom. Dur-ing engineering casualty control drills and duringactual emergencies, the Enginemen should be ableto shift from one source of electrical supply toanother.BATTLE CASUALTIESAs an EN1 or ENC you will be responsiblefor handling battle casualties, you will have toknow the location of isolating and cross-connecting valves, and recognize which of thevalves are remotely controlled. As a general rule,personnel safety will be your first considerationin handling casualties.Effective control of battle casualties dependson a good knowledge of the principal engineer-ing piping systems and related equipment. Thisinformation may be found in the ship’s Engineer-ing Casualty Control Manual, in the DamageControl Book, in the plans of the principleChapter 9—ENGINEERING CASUALTY CONTROL9-13
