1. Damage Control Lesson 10 and 11

2. Learning Objectives Lesson 10 Know the reqs. for looking ahead in shipboard DC training and preparedness. Know DC organization and responsibilities of key personnel Know how shipboard watertight integrity is obtained Know conditions of readiness Know importance of preventative DC

3. Who said it? “Hit hard, hit fast, hit often!”

4. WHY ?

6. DC Overview Ships at sea are isolated from shore help and usually help from other ships; therefore, the crew must be capable of handling any damage the ship may encounter. Ships are dangerous! –Compressed systems –Liquid fuels, other flammables –Water everywhere –No escape!

7. Damage control is a 3-phase activity: Prevent the damage Minimize the effects of damage Restore the ship to an effective fighting unit

8. Plugging Plugging and Praying Shoring First Aid Pipe patching

9. Effective damage control requires: Organization Education Training Maintenance of equipment –Ninety percent of the damage control needed to save a ship takes place before the damage occurs. –Damage control is an all-hands evolution. The crew must be capable of handling damage because there is no place to go at sea. Everyone on a ship must be general damage control qualified and train regularly.

10. HOSEHANDLING!

11. Damage Control Organization POSITION/COC LOCATION COCIC/Bridge CHENG (DC Officer)Main Control DC Assistant DC Central Locker Officers/LeadersRepair Locker Scene LeadersScene of damage Hose teams Scene of damage

12. DCC Damage Control Central –The “brain” of the DC central nervous system. –DCA controls repair parties from here.

13. Repair parties The larger the ship the greater the number of repair parties. REPAIR PARTYLOCATION Repair 2Forward repair Repair 3After repair Repair 5Propulsion repair

14. Watertight Integrity Navy ships are extensively compartmented. This compartmentation acts as a barrier to fires and flooding and prevents further damage. Navy ships are built to withstand the solid flooding of a certain number of compartments without sinking. This passive defense is surrendered if watertight integrity is not maintained through training and repair. Watertight doors and hatches must be maintained and closed properly.

15. Material condition of readiness Explains which doors, hatches and fittings are permitted open (the ship’s level of watertight integrity).

16. Material condition of readiness X-ray (X): Provides the least protection and is set when there is no danger of attack or damage. All fittings marked with a black “X” shall be closed.

17. Material condition of readiness Yoke (Y): Set and maintained at sea and in port during wartime or outside normal working hours. All fittings marked with a black “Y” shall be closed in addition to all “X” fittings.

18. Material condition of readiness Zebra (Z): Set during general quarters; provides the maximum protection for the ship and personnel in battle and emergency situations. All fittings marked with a red “Z” shall be closed, in addition to those marked with an “X” and “Y."

19. Special classifications William (W): Sea suction valves and fittings which serve vital systems’ cooling water, and other fittings and equipment necessary for fire protection and mobility. They are closed only to prevent further damage.

20. Special classifications Circle X and Circle Y: Letter within a black circle. Signifies that may be opened without special permission, but must be secured immediately after use

21. Special classifications Circle Z: Letter within a red circle. May be opened with permission of the CO during general quarters for the comfort of the crew. Guarded when opened for immediate closure, if necessary

22. Special classifications Circle W: Letter within a black circle. Signifies ventilation fittings that are normally open and operating, but may have to be closed to prevent contamination from CBR attack or smoke. When closed, the habitability of the ship decreases rapidly. Should be closed for only very short periods

23. Special classifications Dog Z: Fittings marked with a red “Z” inside a black “D” are closed to darken the ship. (Accesses to weather decks not equipped with light traps or door switches; porthole covers, etc.) D z

24. All Hands It is the responsibility of all hands to maintain the material condition in effect. If it is necessary to break the condition, permission must be obtained (from OOD or DCC). A DC closure log is maintained in DCC at all times.

25. EVERY sailor a FIRE FIGHTER!

26. DC Systems and Equipment Lesson 11 Know how to combat fire and underwater hull damage. Know the four classes of fire and how to combat each. Know the use of equipment and tools used to fight the ship. Know the principles of the fire main system. Know how to DON fire fighting gear.

27. FIRE!...What makes up a fire?

28. A Fire? What makes up a Fire? The Fire Triangle: (free radicals/chemical reaction) Fuel Oxygen Heat

29. What is it? Fuel: The part of the triangle that burns. Paper,wood Oil/gas Paint Wires Textiles/cloth Metal

30. What is it? Oxygen: The part of the triangle that allows for combustion to take place or to burn.

31. What is it? Heat: The temperature that is needed for a substance to exceed it’s flash point, or temp where it burns.

32. HOW!!! The last missing piece! The missing link! FREE RADICALS The chemical reaction between all points of the Fire Triangle. Triangle sometimes called the fire tetrahedron.

33. Classes of fires Alpha: Ash producing fire (paper, clothing, PEOPLE/Screaming Alpha)) Bravo:Oil/fuel fire (JP5, DFM, lube oil) Charlie:Electrical fire (motors, generators) Delta:BAD, Metal fire (magnesium, phosphorus, etc)

34. Colors of smoke Alpha:White, greyish Bravo:BLACK, very BLACK and thick Charlie:Colorful, blueish, orange, purple, red, etc. What ever coloring of wires or type of metal the wire is made of. Delta:VERY bright, white or clearish

35. Extinguishing agents Water CO2 AFFF (Aqueous Film Forming Foam) 94/6 PKP (Purple Potassium Powder) HALON 1301 APC (Aqueous Potassium Carbonate) – Grease Fires in the Galley Jettison

36. What agents to use? Alpha: Any, best is water. – Fire main, sprinkler systems Bravo: AFFF, PKP, APC. AFFF is best. Charlie: CO2, water (fog!), PKP. CO 2 is best, first secure power. Delta: Solid stream, fog or jettison

37. Fire Fighting Equipment

38. SCBA Self Contained Breathing Apparatus –All Ships –All fire party members 30-45 minutes of HP air30-45 minutes of HP air Positive PressurePositive Pressure Worn on backWorn on back

39. SCBAs

40. OBA Oxygen Breathing Apparatus –Being phased out by SCBA –Chem Rx produces OXYGEN –At least 30 min of O2 dependent upon physical activity –Problems Pure O2 Heat Canisters

41. OBAs

42. TEAMWORK!

43. EEBD Emergency Escape Breathing Apparatus –Scott & Ocenco –Min 10 min of air –Escape Only!! –100% Oxygen – stay away from flames after taking it off

44. Installed Systems FIREMAIN HALON 1301 AFFF CO2

45. FIREMAIN Water from the sea Types; –Single main –Horizontal loop –Vertical loop –Composite versions

46. Flooding? Second Biggest Danger on Ship –Watertight Integrity CRITICAL –Pipe patching, plugs, etc

47. The Fire Team…

48. CBR Chemical, Biological, Radiological defense –Newest, and most worrisome threat to ships and soldiers –Ships have advanced methods of prep

49. MCU-2P Standard Navy Gas Mask –Utilizes charcoal filter –Filters all agents –Can drink H2O through fitting –Must replace filter

50. ACPG Advanced Chemical Protection Garment –MOPP (Mission Oriented Protective Posture) Level 3 and 4

51. What does a MIDN need to know on a ship HOW TO EGRESS! General Quarters In the event of a fire: –Call it in (type of fire, who, what space) –Extinguish if possible –Contain –ESCAPE!
