COMPARTMENT CHECKOFF LISTS

Compartment checkoff lists (fig. ^{3-8) provide} an itemized listing of all classified ^{fittings and} closures used in damage control to set the specified material condition of readiness. They are originally prepared and furnished by the ship builder's design agent during the construction of a ship or class of ships. After that it is each ship's responsibility to keep the lists current. Follow the guidelines listed in the Naval Ships' Technical Manual, chapter 079, volume 2, when you check and update your compartment checkoff lists.

All compartments must have a compartment checkoff list permanently posted within them in clear view of the space access. Weather deck areas that have damage control facilities must also have a compartment checkoff list posted. The compartment name and number are entered on the list along with all classified fittings and certain other damage control facilities in the compartment that are necessary to help damage control personnel in the performance of their duties. The information listed for each of the classified fittings and other facilities on a compartment checkoff lists includes the following: . Name of item . Number of item . Location of item l Purpose of item . Classification of item (if classified) l Division responsible for the proper operation of each fitting

When a compartment has more than one entrance, duplicate compartment checkoff lists must be posted at each entrance. The compartment checkoff lists shall be clearly labeled DUPLI-CATE. Partial compartment checkoff lists may be desirable when there are alcoves or areas included within a compartment. The partial compartment checkoff list shall be clearly labeled PARTIAL. The item numbers on the partial list must correspond with the numbers on the original list. Compartment checkoff lists for the weather decks, and some other decks, may be divided by sections;

for example, Main deck, frame 90-120, port side. The DCA maintains a master copy of each original and partial compartment checkoff lists on file in DC central. The DCA, together with the DCPOs, is responsible for ensuring that the compartment checkoff lists are posted and correct.

The individual division officers are responsible for maintaining the list in good physical condition.

The commanding officer, assisted by the DCA, is responsible for filling in the column marked DIVISION RESPONSIBILITY.

The divisions concerned are responsible for securing fittings that are classified as XRAY or YOKE. The ship's repair parties are responsible for securing ZEBRA fittings.

DAMAGE CONTROL CLOSURE LOG

All ships are required to prepare and maintain a damage control closure log (fig. 3-9). To

complete your General Damage Control PQS, you are required to know what the damage control closure log is and how to use it correctly. Strict discipline must be maintained in the modification of a material condition of readiness. As mentioned before, you must obtain permission before you change a material condition setting in any way. Obtain the permission from the DCA or the OOD. During general quarters, repair party officers control the opening and closing of all fittings in their assigned areas. The repair party officers must keep DCC informed so that the ship's DC closure log can be kept up-to-date.

The closure log is maintained at all times, whether the ship is in port or underway. The closure log is used to show the following:

Where the existing material condition of readiness has been modified

The fitting's type, number, and classification

The name, rate, and division of the person who requested permission to open or close the fitting

The date and time the fitting was opened or closed

The date and time the fitting was returned to its specified material condition of readiness setting

The name and rate/rank of person granting permission

The commanding officer prescribes the limit to which the modification of a material condition of readiness may be approved by the DCA or OOD. Reporting the temporary closing of a fitting that should be open is just as important as reporting the opening of one that should be closed. For example, a ZEBRA watertight hatch that is secured at the time general quarters is sounded could seriously interfere with personnel trying to get to their battle stations.

The damage control closure log is normally kept on the quarterdeck in port, on the bridge at sea, and in DCC during genera} quarters. However, if your ship has a 24-hour watch in DCC at all times, the closure log will be kept there no matter where the ship is. The closure log is updated when there is a change in the status of a classified closure or fitting. If a classified closure is to remain open for several days, it must be logged open each day. The maximum time a closure or fitting may be logged open is 24 hours.
