58 Hose Tools Hose strap, hose rope, hose chain Used to carry, pull fire hose Provide more secure means to handle pressurized hose when applying water 13 57

59 Straight Roll Simplest Starts at one end, usually male coupling; to complete roll hose toward other end When complete, female end exposed and male protected in center of roll (Continued) 13 58

60 Straight Roll Used in situations When loaded back on apparatus at fire When returned to quarters for washing When placed in storage Easy loading of minuteman load Methods to indicate need for repair/test 13 59

61 Donut Roll Used in situations where hose is likely to be deployed for use directly from roll (Continued) 13 60

62 Donut Roll Advantages over straight roll Better control Hose rolls out easier Facilitates connecting to other couplings Can be performed by 1-2 firefighters 13 61

63 Twin Donut Roll Works well on 1½-inch (38 mm) and 1¾-inch (45 mm) hose Creates compact roll that is easily transported, carried If couplings offset about 1 foot (0.3 m), can be coupled together after roll tied 13 62

64 Self-Locking Twin Donut Roll Twin donut roll with built-in carrying loop formed from hose itself Loop locks over couplings to keep intact Length of carrying loop may be adjusted 13 63

65 Hose Beds Hose compartments on fire apparatus Vary in size, shape Sometimes built for specific needs Front of hose bed Rear of hose bed Split beds 13 64

66 Hose Loading Guidelines Check gaskets, swivel before connecting couplings Keep flat sides of hose in same plane when two sections connected Tighten couplings hand-tight Remove kinks, twists when bent to form loop in hose bed (Continued) 13 65

67 Hose Loading Guidelines Make short fold/reverse bend in hose during loading so couplings not too close to front or rear of hose bed and will not flip over when pulled out of bed Load large-diameter hose with all couplings near front of bed Do not pack too tightly 13 66

68 Accordion Load Derives name from manner in which it appears after loading Procedure Advantages 13 67

69 Horseshoe Load Named for way it appears after loading Procedure Advantage Disadvantages (Continued) 13 68

70 Horseshoe Load In single hose load, may be started on either side Steps for split hose bed 13 69

71 Flat Load Easiest to load Suitable for any size supply hose Best way for large-diameter hose Advantage Disadvantage (Continued) 13 70

72 Flat Load May be started on either side of single hose bed In split hose bed, lay first length against partition with coupling hanging appropriate distance below hose bed Large-diameter hose 13 71

73 Finishes for Forward Lays Designed to facilitate making hydrant connection Not as elaborate as finishes for reverse lays (Continued) 13 72

74 Finishes for Forward Lays Straight finish Last length or two of hose flaked loosely back and forth across top of hose load Associated with forward-lay operation Hydrant wrench, gate valve, adapters strapped to hose near female coupling 13 73

75 Finishes for Reverse Lays Reverse horseshoe finish Similar to horseshoe load One or two 100-foot (30 m) lengths of hose Can be used with any size attack hose Can be used for preconnected line Can be loaded in two or three layers Can be pulled from bed for arm carry (Continued) 13 74

76 Finishes for Reverse Lays Skid load finish Folding last three lengths of hose into compact bundle on top of rest of load Begins by forming 3+ pull loops extending beyond end of hose load Rest of hose accordion-folded across hose used to form pull loops 13 75

77 Preconnected Hose Loads for Attack Lines Primary lines used for fire attack by most departments Connected to discharge valve, placed in area other than main hose bed Range from feet (15-75 m) Can be carried in several places 13 76

78 Preconnected Flat Load Adaptable for varying widths of hose beds Often used in transverse beds Similar to flat load for large supply hose except Preconnected Loops provided to aid in pulling from bed 13 77

79 Triple Layer Load Begins with hose folded in three layers Designed to be pulled by one person Disadvantage Can be used for all sizes attack lines Often preferred for larger lines 13 78

80 Minuteman Load Designed to be pulled, advanced by one Advantage Pays off shoulder as firefighter advances toward fire Well suited for narrow hose bed Disadvantages 13 79

81 Booster Hose Reels Used for booster lines May be mounted in any of several places on apparatus May be hand- or power-operated Should be loaded one layer at a time in an even manner 13 80

82 Guidelines When Laying Hose Do not ride in standing position to lay hose when apparatus moving Drive apparatus at speed no greater than one that allows couplings to clear tailboard as hose leaves bed Lay hose to one side of roadway 13 81

83 Forward Lay Hose laid from water source to fire Used when source is a hydrant and pumper must be positioned near fire Hose beds should be loaded so first coupling off is female Operation (Continued) 13 82

84 Forward Lay Advantages Disadvantages Information for firefighter at hydrant Making hydrant connection Using four-way hydrant valves 13 83

85 Reverse Lay Hose laid from fire to water source Used when pumper must first go to fire location so size-up can be made before laying supply line Most expedient way to lay hose if apparatus must stay close to water (Continued) 13 84

86 Reverse Lay Hose beds should be loaded so first coupling off hose bed is male Has become standard method for setting up relay pumping operation when using 2½-inch or 3-inch (65 or 77 mm) hose as supply line (Continued) 13 85

87 Reverse Lay Long lays of large hose may require pumper at hydrant to increase pressure in supply hose Most direct way to supplement pressure, set up drafting operations Disadvantages (Continued) 13 86

88 Reverse Lay Procedures if operation involves two pumpers Does not require four-way hydrant valve Also used when pumper arrives at fire and must work alone for extended time (Continued) 13 87

89 Reverse Lay Making hydrant connections with soft intake hose Making hydrant connections with hard intake hose 13 88

90 Split Lay Any of a number of ways to lay multiple supply hoses with a single engine Various types If equipped with sexless couplings, direction of lay is unimportant May other options when hose bed is divided 13 89

91 Pulling Preconnected Hoselines Preconnected flat load Minuteman load Triple layer load 13 90

92 Other (Not Preconnected) Hoselines Usually 2½-inches (65 mm) or larger Wyed lines Shoulder loads from flat/horseshoe loads Shoulder loads from accordion or flat loads 13 91

93 Working Line Drag One of quickest, easiest ways to move fire hose at ground level Use limited by available personnel 13 92

94 Advancing Hoselines Difficult when deploying up or down stairways, from standpipes, up ladders, deep into buildings Easier when uncharged 13 93

95 Guidelines When Advancing Hoseline into Burning Structure Bleed air from charged hoselines before entering Position nozzle operator, all members of hose team on same side of hoseline Check doors for heat before opening (Continued) 13 94

96 Guidelines When Advancing Hoseline into Burning Structure Stay low, avoid blocking ventilation openings Chock self-closing doors open Check for, remove kinks from line 13 95

97 Advancing Hose Up Stairway Should be advanced up stairways uncharged when conditions allow Lay uncharged hose against outside wall to keep stairs clear as possible, avoid sharp bends and kinks in hose If possible, position firefighter at every turn/point of resistance 13 96

98 Advancing Hose Down Stairway Advancing uncharged hoseline easier than charged Advancing uncharged line recommended only when no fire, very minor fire (Continued) 13 97

99 Advancing Hose Down Stairway Excess hose should be flaked outside stairwall Firefighters must be positioned at corners, pinch points 13 98

100 Advancing Hose From Standpipe Getting hose to upper floors of high-rise buildings can be challenging One solution is to have hose rolls or packs on apparatus ready to carry aloft and then connect to standpipe system (Continued) 13 99

101 Advancing Hose From Standpipe Hose must be brought to fire floor over aerial ladder or by interior stairway Crews normally stop one floor below fire floor and connect to standpipe If standpipe in enclosed stairwell, it is acceptable to hook up on fire floor (Continued)

102 Advancing Hose From Standpipe Steps once at standpipe connection Be alert for pressure-relief devices and follow SOPs for removal/connection If using certain sizes of hose, place gated wye on standpipe outlet (Continued)

103 Advancing Hose From Standpipe 2½-inch (65 mm) attack line may be used depending on size, nature of fire Extra hose should be flaked up stairs toward floor above fire During pickup operations, carefully drain water to prevent unnecessary damage

104 Advancing Hose Up Ladder Easier and safer with uncharged line Advancing charged line Operating hoseline from ladder

105 Controlling Loose Hoseline Very dangerous because it may flail about or whip back and forth Firefighters, bystanders may be seriously injured or killed Methods for controlling

106 Replacing Burst Sections Hose clamp or kink can be used to stop flow of water when replacing burst section of hose Two additional sections of hose should be used to replace any one bad section

107 Operating Small Handlines One Firefighter Method Only used during overhaul after fire or for very small outdoor nuisance fires Requires hoseline to be straight at least 10 feet (3 m) behind nozzle Firefighter should hold nozzle with one hand and hose with the other

108 Operating Small Handlines Two Firefighter Method Usually needed when nozzle must be advanced Nozzle operator duties Backup firefighter duties

109 Operating Large Handlines One Firefighter Method NOT recommended when nozzle is connected to large handline May be used during exposure protection/overhaul operations if master stream device unavailable (Continued)

110 Operating Large Handlines One Firefighter Method Large loop formed that crosses over line behind nozzle Firefighter sits on intersection where hose crosses and directs stream (Continued)

111 Operating Large Handlines One Firefighter Method To reduce fatigue, nozzle operator can use hose strap or utility strap looped over shoulder or reduce nozzle flow if conditions allow Does not permit much maneuvering

112 Operating Large Handlines Two Firefighter Method #1 Uses means of anchoring hose because of nozzle reaction Nozzle operator duties Backup firefighter duties

113 Operating Large Handlines Two Firefighter Method #2 Uses hose rope tools or utility straps to assist in anchoring hose Nozzle operator duties Backup firefighter duties

114 Operating Large Handlines Three Firefighter Method In all cases, positioning of nozzle operator same as for two-firefighter method (Continued)

115 Operating Large Handlines Three Firefighter Method Some departments prefer first backup firefighter to stand behind nozzle operator with third firefighter kneeling on hose behind second firefighter Another method is for all firefighters to use hose straps and remain standing

116 Summary To fight fires safely and effectively, firefighters must know the capabilities and limitations of the various types of fire hose used in their departments. (Continued)

117 Summary Firefighters must know the differences between supply hose and attack hose and how to use each one. Firefighters must know how to load hose onto apparatus and how to make the various hose load finishes used in their department
