11. Firefighter I 17–10 Salvage and Overhaul Most effective means of loss control Restoration of the property

12. Firefighter I 17–11 Salvage Operations that aid in reducing primary and secondary damage during fire fighting Primary damage is caused by the fire Secondary damage is caused by fire suppression activities

13. Firefighter I 17–12 Salvage Both primary and secondary damage can be minimized through salvage Some damages cannot be avoided Starts as soon as adequate personnel are available May be done simultaneously with fire attack

14. Firefighter I 17–13 Overhaul Consists of operations involved in searching for and extinguishing hidden or remaining fires Protecting the scene and preserving evidence are components of overhaul

15. Firefighter I 17–14 Overhaul If possible, do not start overhaul operations until Fire is under control Fire cause has been determined Evidence has been identified and protected

16. Firefighter I 17–15 Salvage Methods and operating procedures by which firefighters attempt to save property and reduce further damage Removing property Covering property Other means

17. Firefighter I 17–16 Salvage Proper salvage operations Early planning Knowing the procedures Being familiar with tools and equipment

18. Firefighter I 17–17 Planning for Salvage Operations Efficient operations require planning and training SOPs should be developed

19. Firefighter I 17–18 Planning for Salvage Operations Preincident plans High-value contents Residential occupancies Commercial occupancies Work with loss-control representatives

20. Firefighter I 17–19 Salvage Procedures Operations can be started at same time as fire attack Group building contents into compact piles

25. Firefighter I 17–24 Salvage Covers Synthetic covers Lightweight Easy to handle Economical Indoor and outdoor use Some covers may be disposable

26. Firefighter I 17–25 Salvage Cover Maintenance Proper cleaning, drying, and repairing increases service life

27. Firefighter I 17–26 Salvage Cover Maintenance Canvas salvage covers Wetting or rinsing with hose stream and scrubbing with a broom Detergent solution if needed Don’t let dry when dirty Should be completely dry before being folded and placed in service

28. Firefighter I 17–27 Salvage Cover Maintenance Synthetic salvage covers Do not require as much maintenance as canvas May be folded wet Usually better to let dry first After salvage covers are dry, examine for damage

29. Firefighter I 17–28 Salvage Cover Maintenance Look up at the underside to locate holes Mark holes with chalk or marking pen Repair holes

30. Firefighter I 17–29 Salvage Equipment Should be located in a readily accessible area on apparatus SOPs dictate where equipment is carried and who performs operations

31. Firefighter I 17–30 Salvage Equipment Keep smaller tools/equipment in a salvage toolbox Plastic tub may be used for supplies

32. Firefighter I 17–31 Typical Salvage Equipment Electrician’s pliers Sidecutters Various chisels Tin snips Tin roof cutter Adjustable wrenches Pipe wrenches

43. Firefighter I 17–42 One-Firefighter Spread with a Rolled Salvage Cover One person can quickly unroll a cover May be carried on the shoulder or under the arm

44. Firefighter I 17–43 One-Firefighter Spread with a Folded Salvage Cover Two firefighters are needed to make fold May be carried in any manner

45. Firefighter I 17–44 Two-Firefighter Spread with a Folded Salvage Cover Large salvage covers cannot be easily handled by a single firefighter Carry this fold on the shoulder with open edges next to neck

46. Firefighter I 17–45 Two-Firefighter Spread with a Folded Salvage Cover Position cover so carrier can grab lower pair of corners and second firefighter can grab uppermost pair

47. Firefighter I 17–46 Two-Firefighter Spread with a Folded Salvage Cover Balloon throw is most common method for deployment

48. Firefighter I 17–47 Using Chutes: Removing Water Practical way to remove water that comes through the ceiling from upper floor May be constructed on floor below fire fighting operations

49. Firefighter I 17–48 Using Chutes: Removing Water Prepared chutes are approximately 10 feet (3 m) long Chutes can be constructed from plastic sheeting, a heavy-duty stapler, and duct tape

50. Firefighter I 17–49 Using Chutes: Constructing a Catchall Constructed from a salvage cover placed on the floor to hold small amounts of water

51. Firefighter I 17–50 Using Chutes: Constructing a Catchall Temporarily control large amounts of water Place into position as soon as possible Usually requires two people

52. Firefighter I 17–51 Splicing Covers Used when: Objects/groupings are large Long chutes or catchalls need to be made Splice covers with watertight joints

53. Firefighter I 17–52 Splicing a Chute to a Catchall Method of removing accumulated water should be prepared Submersible pumps may be used Water chute spliced to the catchall

64. Firefighter I 17–63 Supervision of Overhaul By a supervisor/officer not directly engaged in overhaul tasks Fire investigator should be involved

65. Firefighter I 17–64 Fire Safety During Overhaul Size of charged hoselines in overhaul may not be the same Disconnecting fire apparatus from hydrants Departmental SOPs may dictate one supply line left in place

66. Firefighter I 17–65 Fire Safety During Overhaul Attack lines used for overhaul are typically 1½ inch (38 mm) or 1¾ inch (45 mm) Water fire extinguishers or booster hoses may be used for small fires One attack line should be available

67. Firefighter I 17–66 Fire Safety During Overhaul Place nozzle so it will not cause additional damage Do not allow water damage from leaking hoselines Use a 100-foot (30 m) hoseline as the first section on attack lines

68. Firefighter I 17–67 Overhaul Safety Considerations Maintain situational awareness Work in teams of two or more Maintain awareness of exit routes Maintain a RIC

74. Firefighter I 17–73 Overhaul Procedures Begins in the area of most severe fire involvement Looking for fire extension should begin as soon as possible after fire is declared under control Systematically carried out

75. Firefighter I 17–74 Overhaul Procedures If fire extended to other areas, path must be determined When floor beams are burned at ends or where they enter a party wall, flush the voids in the wall with water

76. Firefighter I 17–75 Overhaul Procedures Check far side of the wall to see if fire or water has come through. Thoroughly check insulation materials

77. Firefighter I 17–76 Understanding Basic Building Construction Assists firefighters in searching for hidden fires Windows or doors Fire may remain within frames or casings Open these areas to ensure complete extinguishment

78. Firefighter I 17–77 Building Construction and Overhaul When fire has burned around combustible roof or cornice, open cornice and inspect for hidden fires Balloon construction — Check the attic and basement for fire extension

79. Firefighter I 17–78 Building Construction and Overhaul Opening concealed spaces Move the furnishings of the room to locations where they will not be damaged Consider electrical wiring, gas piping, or plumbing Make neat, planned openings to ensure extinguishment and facilitate restoration

80. Firefighter I 17–79 Building Construction and Overhaul Ceilings may be opened from below using a pike pole or other tool The plaster must first be broken on some ceilings When pulling a ceiling, do not stand directly under area to be opened

81. Firefighter I 17–80 Building Construction and Overhaul Always position body between area being pulled and doorway to keep exit route from being blocked Always wear full protective clothing, including eye and respiratory protection

82. Firefighter I 17–81 Building Construction and Overhaul Small burning objects Submerge entire objects in containers of water Bathtubs, sinks, lavatories, wash tubs Remove larger furnishings to the outside

83. Firefighter I 17–82 Building Construction and Overhaul Scorched or partially burned articles may prove helpful to an investigator Use of wetting agents such as Class A foam is valuable Cotton, upholstery, and baled goods Must break bales of rags, cotton, hay apart
