Do not permit vehicles to run over fire hose. Examine couplings when hose is washed and dried. Examine couplings when hose is washed and dried. Remove gasket, and twist swivel in warm, soapy water. Remove gasket, and twist swivel in warm, soapy water. Clean threads to remove tar, dirt, gravel, and oil. Clean threads to remove tar, dirt, gravel, and oil. Inspect gasket, and replace if cracked or creased. Inspect gasket, and replace if cracked or creased. TS 12A–8

HOSE LOADING GUIDELINES Check gaskets and swivel before connecting any coupling. Check gaskets and swivel before connecting any coupling. Keep flat sides of hose in same plane when connecting two sections. Keep flat sides of hose in same plane when connecting two sections. Tighten couplings hand-tight when two sections are connected. Tighten couplings hand-tight when two sections are connected. Remove wrinkles from hose when it must be bent to form a loop in the hose bed — press with the fingers so that inside bend is smoothly folded. Remove wrinkles from hose when it must be bent to form a loop in the hose bed — press with the fingers so that inside bend is smoothly folded. TS 12A–9a

HOSE LOADING GUIDELINES (cont.) During loading, make a short fold or reverse bend in the hose so that couplings do not have to be turned around to be pulled out of bed. During loading, make a short fold or reverse bend in the hose so that couplings do not have to be turned around to be pulled out of bed. Load large diameter hose with all couplings placed at front of bed. Load large diameter hose with all couplings placed at front of bed. Do not pack hose too tightly. Do not pack hose too tightly. TS 12A–9b

HOSE LOADING METHODS Coupled and folded into hose bed Coupled and folded into hose bed — Attack and supply lines Preconnected and folded into hose bed — Preconnected and folded into hose bed — Collapsible attack and supply lines Racked, compartmentalized, or secured to apparatus Racked, compartmentalized, or secured to apparatus  Preconnected or unconnected soft-sleeve and hard- suction intake hose  Attack and intake hose that is loaded on raised trays or in tailboard compartments, side bins, or front bumper wells TS 12A–10a

HOSE LOADING METHODS (cont.) Preconnected and reel wound Preconnected and reel wound  Noncollapsible booster line  Some large diameter hose  Some attack handlines Tied bundles or rolls Tied bundles or rolls  Standpipe hose  Wildland attack hose TS 12A–10b

ACCORDION LOAD Advantages Advantages  Simple design  Easily loaded  Easily shoulder-loaded for carrying Disadvantage Disadvantage — Loaded on edge, subjecting edges to wear from apparatus vibration TS 12A–11

HORSESHOE LOAD Advantage Advantage — Fewer sharp bends than accordion or flat loads Disadvantages Disadvantages  In wide hose beds, hose may come out in a wavy, snakelike lay in the street as hose is pulled from one side of the bed to the other  Folds for shoulder carry cannot be obtained as easily as for accordion load  Large diameter hose tends to fall over in bed and may become entangled TS 12A–12

FLAT LOAD Advantages Advantages  Easiest to load  Suited to any size supply hose (best way to load large diameter hose)  Folds lie flat rather than on edge so is not subject to edge abrasion Disadvantages Disadvantages  Folds contain sharp bends at both ends  Hose must be reloaded periodically to relocate the bends TS 12A–13

PRECONNECTED HOSE LOADS FOR ATTACK LINES Preconnected Flat Load Triple Layer Load Minuteman Load TS 12A–14

HOSE LOAD FINISHES Straight Finish Reverse Horseshoe Finish TS 12A–15

STRAIGHT HOSE ROLL Used when hose will be placed in storage, especially rack storage Used when hose will be placed in storage, especially rack storage Used when hose will be returned to quarters for washing Used when hose will be returned to quarters for washing Reversed (male coupling exposed) to identify a damaged coupling or hose section Reversed (male coupling exposed) to identify a damaged coupling or hose section TS 12A–16

DONUT HOSE ROLL Used when hose is going to be deployed directly from a roll Used when hose is going to be deployed directly from a roll Advantages over straight roll Advantages over straight roll  Both ends are available on the outside of the roll  The hose can be quickly unrolled and placed in service  The hose is less likely to kink or spiral when unrolled  One or two firefighters can perform a donut roll TS 12A–17
