Damage control.

First of all, fair winds and following seas to CWO2 Robert Morrow and thank you for all the work you have done for Submarine Damage Control, and the Submarine Auxiliary community.

I am MMC/SS Fannin reporting from the USS Jefferson City SSN-759. I am qualified on 637, and 688I class submarines, with tours as Damage Control Petty Officer on both classes of boats. So I know how important good information in a FLASH and support from the Safety Center can be at the deck plate level.

School--In the 7 surveys I have done, it is apparent that the Damage Control Petty Officer School (CIN A-495-2054) is being underutilized. This school offers a great opportunity to conduct PMS and maintenance on things like SCBAs (which continue to lead the way in the world of material deficiencies with under pressurized cylinders) and the Galley Range Guard (a close second with cable travel, and cleanliness issues) and provides a great level of knowledge foundation for our young sailors. This school is designed to provide the ship's DCPO's a more in depth look at the gear that they own and how to maintain it. Don't forget this is a required school per the STMPS report and is available at all bases. If you cannot find this course in the normal catalog call your local training facility and attempt to schedule a special convening.

AFFF extinguishers--Everyone knows the requirements for the pms to be performed and how to fill out the extinguisher tags properly. But after several surveys of boats on both coasts and different classes, it is becoming apparent that some problems are coming up. The scale required to perform the R-2 and the R-48 pms (NSN 9V-6670-01-035-5507) is not being maintained in calibration or in operational condition. Also the correct weights are not being recorded on the proper tags (NAVSEA 9555/1 S/N 0116-LF-114-3100). This scale is a 0-60 lb scale in 1 oz graduations. The trick is that the face only reads 0-20 lbs. So in order to weigh the extinguishers properly you have to watch the needle make one complete revolution and then see where the needle stops. You then should add the number where the needle stopped plus 20 lbs to get the accurate weight of the extinguisher. This weight is recorded on the tag in the manner of lbs and oz. That means the reading should not be rounded up or down to the nearest whole pound. The correct range is from 27 lbs 9oz-28 lbs 4 oz. And please do not forget to transfer the weight value over to the next line or new tag, when you are performing the R-2, R-48 or the Q-10R and you need a new tag.

Band-It Buckles--Here is some more follow up on the buckle issue from the last FLASH. I am still currently awaiting word from NAVSEA as to how and what will be done with these buckles. But I have more info to help segregate these new buckles from the old reliable ones. The part number for the authorized buckles is C25499. The part number for the buckles that need to be removed from use for the time being is C15499.
