FIRE HOSE TERMSFIRE HOSE TERMS

• Expansion-ring gasket Expansion-ring gasket — Gasket used at the end of hose where it is expanded into coupling shank

• Fire hose Fire hose — Type of flexible tube used to carry water under pressure from source of supply to point where it is discharged

• Hose bed Hose bed — Hose storage compartment

• Dutchman Dutchman — Reverse bend at coupling of bedded hose that allows it to be payed out without bending

• Flake Flake — To lay out fire hose in a loose accordion pattern to reduce chances of hose tangling and kinking when pulled

ACCORDION LOADACCORDION 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 LOADHORSESHOE LOAD

• Advantage Advantage — Fewer sharp bends than accordion or flat loads

• DisadvantagesDisadvantages

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 LOADFLAT 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

DONUT HOSE ROLLDONUT HOSE ROLL

• Used when hose is going to be deployed Used when hose is going to be deployed directly from a rolldirectly from a roll

• Advantages over straight rollAdvantages 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
