DCC SUPERVISOR/LOCKER LEADER.-

The DCC supervisor assumes overall charge of the in-port fire party. This person is normally a chief petty officer or a junior officer. (On ships where a DCC supervisor is not assigned, the locker leader assumes the overall charge of the in-port fire party.) The supervisor stays in the vicinity of the repair locker or DCC during all emergency evolutions. As the person in charge, the supervisor organizes and trains the fire party to work effectively as a team in combating any situation that arises. The supervisor must also analyze and evaluate any situation and provide information and guidance to the on-scene leader by message. The DCC supervisor will have schematics of various ship's systems and the ship's compartmentation available. These are helpful to persons who plot damage reports and provide guidance to the on-scene leader.

The DCC supervisor should be qualified as an on-scene leader, an investigator, a fire fighter, a DC repairman, and in CBR evaluation. An investigator is normally a collateral duty of the nozzleman. However, all personnel on a fire party should complete their PQS for investigator, nozzleman, and hoseman. DC repairmen should be qualified in shoring, dewatering, desmoking, and making temporary repairs. Temporary repairs are normally made to piping, bulkheads, the hull, and other structural members of the ship.

ON-SCENE LEADER.- The on-scene leader is the person in charge of the fire party at the scene. To qualify for the job of on-scene leader, you must complete the appropriate PQS. Once assigned the job, you will direct all efforts of the fire part y to combat the emergency situation. You will report to the DCC supervisor, using DC message blanks and sound-powered telephones. All other personnel on the fire party will report directly to you. To qualify as an on-scene leader, you should be qualified as an investigator, a fire fighter, and a DC repairman.

NO. 1 NOZZLEMAN.- As the No. 1 nozzleman, you will man the attack hose nozzle. You will be in charge of the fire team that enters the compartment to extinguish the fire. For your protection, you will be required to wear an OBA. Once the fire is extinguished, you will order the backup hose to be pulled back to the entrance of the space and the reflash watch set. Then you will use your personnel available inside the compartment to overhaul the fire, conduct atmospheric tests, desmoke the compartment, and investigate the damage. When conducting atmospheric tests, you will have the accessman/ compartment tester check the space for the percentage of oxygen content and the presence of explosive and toxic gases. (The duties of the accessman/compartment tester will be explained later in this section.) You should be qualified in first aid, the operation of all fire-fighting equipment, and the procedures for overhauling a fire.

In the event of a collision or flooding, you will act as an investigator. Here you will check for heat, smoke, flames, fumes, parted electrical cables, leaking pipes or seams, visual damage, and any other unusual condition. Do the initial investigation quickly but thoroughly. You will then report to the on-scene leader. The on-scene leader will then have you make a slower, more detailed investigation. Investigators should be qualified in investigation procedures, making damage reports, use of the legend system, and fire fighting.

NO. 2 NOZZLEMAN.- AS the No. 2 nozzleman, you will man the back up hose nozzle with an applicator attached to it. Your task is to provide protection for yourself and the No. 1 nozzleman. You do this by maintaining a lowvelocity water screen between yourselves and the flames. After the fire is out, you will help the accessman/compartment tester conduct the atmospheric tests. Until the compartment is determined to be safe to enter, only persons wearing an OBA may enter the space. Your qualifications are the same as those for the

No. 1 nozzleman. You will help the No. 1 nozzleman conduct investigations in the event of a collision or flooding.

NO. 1 HOSEMAN.- As the No. 1 hoseman, you will have several duties. You will wear an OBA. You will run the attack hose from the fire plug to the scene, and you will keep the hose from getting fouled while fighting the fire. The No. 1 nozzleman will be able to handle the hose and nozzle better if you keep the weight and tension of the hose off the No. 1 nozzleman. Your other duties include the relaying of spoken messages and orders between the on-scene leader and the No. 1 nozzleman. You will assume the duties of the reflash watch when directed to do so. After the fire is out, overhauled, and the space is safe to enter, you will help clean up the compartment.

In the event of a collision or flooding, you will be on the shoring detail. There you will reinforce weakened bulkheads, brace warped watertight closures, and patch holes in bulkheads and piping. Shoring, plugging, and patching procedures will be discussed in a later chapter.

NO. 2 HOSEMAN.- As the No. 2 hoseman, you will wear an OBA and have duties similar to those of the No. 1 hoseman. You will run the backup hose from the fire plug to the scene. Ensure that the appropriate applicator is installed in the nozzle. While fighting the fire, keep the hoses from getting fouled. Also, the No. 2 nozzleman can handle the hose and nozzle better if you keep the weight and tension of the hose off the No. 2 nozzleman. Your other duties are to relay spoken messages and orders between the on-scene leader and the No. 1 nozzleman. When directed, you will assist in the overhaul of the fire and any other action required.

In the event of a collision or flooding, you will be part of the pump detail. The pump detail transports the dewatering equipment to the scene and sets it up. Once the equipment is on the scene and rigged, notify the on-scene leader. The onscene leader will tell you when to activate your equipment. As a No. 2 hoseman, you should be able to operate all types of dewatering equipment and to troubleshoot problems that arise.

NO. 1 PLUGMAN.- As the No. 1 plugman, you will connect the hose to the fire plug. When directed to do so, and while the nozzle is closed, open the fire plug valve to activate the hose. You will need to keep an eye on the hose for loss of water pressure or a hose rupture. If there is a loss of water pressure, flush out the marine strainer by using the strainer lever. In the event of a ruptured fire hose, secure the fire plug, replace the ruptured section of hose, and reactivate the hose as quickly as possible. In the event of a collision or flooding, you will be assigned to the shoring detail.

NO. 2 PLUGMAN.- As the No. 2 plugman, you will connect the backup hose to the fire plug. Your duties are the same as those of the No. 1 plugman. In the event of a collision or flooding, you will also be assigned to the shoring detail.

ELECTRICIAN.- When there is fire or flooding, the repair party electrician will immediately secure electrical power to all compartments that are affected by the casualty. The electrician will report to the on-scene leader when the electrical power is secured. The electrician is responsible for the plugging in, energizing, and de-energizing of the electrical submersible pumps, red devil blowers, and any other electrical equipment required. Other members of the fire party may set up the equipment for use; however, they are not to plug in, energize, or de-energize the equipment. Once the casualty is corrected, the electrician will investigate the compartments for electrical damage when directed to do so by the on-scene leader. The electrician will complete repairs to vital electrical systems as soon as possible. Repairs to nonvital electrical systems will be completed as time allows.

ACCESSMAN/COMPARTMENT TESTER.- If you are assigned as the accessman/compartment tester, you will have dual responsibilities. First, you will provide forcible-entry tools at the scene. Second, you will provide the compartment atmosphere-testing devices. When the hose teams are ready to enter a space, you will open the door, hatch, or scuttle. If the space is locked, you will have to decide which forcible-entry tools to use. There are times when you have to clear a route so that the fire party can gain access to the fire.

Once entry has been made, you will stand by to assist where needed until the on-scene leader orders you to test the atmosphere within the compartment. When conducting the tests, you will operate the test equipment from out side the space. A hoseman or nozzleman with the sensor probe or sampling hose will move about the compartment being tested. These tests are used to check for explosive gases, toxic gases, and sufficient oxygen content to sustain life. In the event of a collision or flooding, you will be on the pump detail.

STRETCHER BEARER.- If you are assigned as a stretcher bearer, you will be required to take the repair locker first-aid kit, or box, to or near the scene. If medical department personnel are available, you will help them in administering first aid, as required. In the absence of medical department personnel, you will render basic first aid and then assist in the evacuation of injured personnel to battle dressing stations.

BOUNDARY SETTER.- There are two boundary setters assigned to a fire party. One is responsible for setting the forward boundaries while the other is responsible for setting the aft boundaries. Fire/flooding boundaries are set to contain a casualty within the smallest area possible. In other words, a fire should be confined to one compartment if possible. Flooding should be confined to keep it from progressing and seriously affecting the ship's stability. The forward and after bulkheads of a compartment are normally used as the fire boundaries.

When acting as boundary setter during a fire, you will need a means to keep the bulkheads and decks cool. A fire hose is normally used if available. Otherwise, you may use a bucket of water and a swab. You will also need to move all combustibles away from the bulkhead that is adjacent to the fire, if possible.

In the case of flooding, the first set of watertight transverse bulkheads forward and aft of the flooded compartment are used as the flooding boundaries. While acting as boundary setter during flooding, you will have to keep a watchful eye on the situation. If a closure or seam begins to leak or if the bulkhead starts panting, report it to the on-scene leader.

C02 MAN.- As the person in charge of CO2, you will provide portable CO2 fire extinguishers to the scene. Persons wearing the OBAs will use the CO2 extinguishers to fight electrical fires. The number of extinguishers required will vary depending on the size of the fire. However, a minimum of two extinguishers are to be provided. In the event of a collision or flooding, CO2 bottles will not be required initially. Therefore, you will assist the accessman on the pump detail.

FOAM MAN.- As the foam man, you will be responsible for the operation of the aqueous film forming foam (AFFF) stations and equipment. If the fire's location is not protected by an installed AFFF system, you will deliver two cans of foam to the location of the portable foam-producing equipment. You might be required to obtain additional AFFF to fight a class BRAVO fire. In the event of a collision or flooding, you will be assigned to the pump detail. Chapter 5 will discuss the AFFF systems.

SPRINKLEMAN.- A Gunner's Mate is normally assigned as the sprinkleman. The sprinkleman will stand by the appropriate magazine sprinkling control station in the event that an order is given to activate the system. The sprinkleman informs the on-scene leader when a magazine control station is manned. In the event of a collision or flooding, the sprinkleman will assist the pump detail.

DCC/REPAIR LOCKER PHONE TALKER.- If you are assigned as the DCC/ repair locker phone talker, you will report to DCC or the repair locker. There you will man the phone between the DCC supervisor and the on-scene leader. You will receive messages from the on-scene leader, via the on-scene phone talker, and relay them to the DCC supervisor. You will relay all messages from the DCC supervisor to the on-scene phone talker.

ON-SCENE PHONE TALKER.- If you are assigned as the on-scene phone talker, you will man the phone at the scene. Here you will receive messages from the DCC supervisor, via the DCC phone talker, and relay them to the on-scene leader. You will also relay all messages from the on-scene leader to the DCC phone talker.

MESSENGER.- If you are assigned as the messenger, you will be responsible for carrying messages between the on-scene leader and the DCC supervisor. You will need to be thoroughly familiar with your ship and know how to get from one place to another. You are to stay near the on-scene leader at all times except when you are taking a message to the DCC supervisor. When you are carrying a message from one point to another, do so quickly. The on-scene leader may have another message ready for you when you get back.
