  2. Hose Appliances • Any piece of hardware used with fire hose to deliver water (Continued) Firefighter II

  3. Hose Appliances • Valves • Control flow of water in hoselines, at hydrants, at pumpers • Ball valves • Gate valves • Butterfly valves • Clapper valves (Continued) Firefighter II

  4. Hose Appliances • Valve devices • Allow number of hoselines operating on fire ground to be increased/decreased • Wye appliances • Siamese appliances (Continued) Firefighter II

  5. Hose Appliances • Valve devices • Water thief appliances • Large-diameter hose appliances • Hydrant valves (Continued) Firefighter II

  6. DISCUSSION QUESTION What are some other names for hydrant valves? Firefighter II

  7. Hose Appliances • Fittings (Continued) Firefighter II

  8. Hose Appliances • Intake strainers • Devices attached to drafting end of hard intake to keep debris from entering fire pump • Guidelines for use Firefighter II

  9. Hose Tools • Hose roller • Prevents damage to hose that can occur when dragged over sharp corners such as roof edges, windowsills (Continued) Firefighter II

  10. Hose Tools • Hose roller • Consists of metal frame with two or more rollers • Can be used for protecting rope from similar edges (Continued) Firefighter II

  11. Hose Tools • Hose jacket • Can be installed on ruptured section of hoseline to temporarily close rupture (Continued) Firefighter II

  12. Hose Tools • Hose jacket • Consists of hinged two-piece metal cylinder • Made in two sizes • Encloses hose so can operate at full power • Can be used to connect mismatched hose (Continued) Firefighter II

  13. Hose Tools • Hose clamp • Can be used to stop flow of water in hoseline (Continued) Firefighter II

  14. Hose Tools • Hose clamp • Three types — Screw-down, press-down, hydraulic press • Can injure firefighters/damage hose • Several general rules for use (Continued) Firefighter II

  15. Hose Tools • Spanner • Used to tighten/loosen couplings • May have other built-in features (Continued) Firefighter II

  16. Hose Tools • Hydrant wrench • Used to remove caps from hydrant outlets, open hydrant valves • Equipped with pentagonal opening fitting most standard hydrant operating nuts • May be equipped with spanner (Continued) Firefighter II

  17. Hose Tools • Rubber mallet — Strike lugs to tighten/loosen couplings • Hose bridge/ramp • Help prevent damage to hose • Should be used where hose laid across street (Continued) Firefighter II

  18. Hose Tools • Hose bridge/ramp • Can be positioned over small spills • Can be used as chafing blocks (Continued) Firefighter II

  19. Hose Tools • Chafing blocks • Used to protect fire hose where subjected to rubbing from vibrations • Useful where intake hose comes in contact with pavement • May be wood, leather, old truck tires (Continued) Firefighter II

  20. 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 Firefighter II

  21. Hose Loading Guidelines • Load large-diameter hose with all couplings near front of bed • Do not pack too tightly; should permit gloved hand between folds Firefighter I

  22. Accordion Load • Derives name from manner in which it appears after loading • Procedure • Advantages Firefighter I

  23. Horseshoe Load • Named for way it appears after loading • Procedure • Advantage • Disadvantages (Continued) Firefighter I

  24. Horseshoe Load • In single hose load, may be started on either side • Steps for split hose bed Firefighter I

  25. Flat Load • Easiest to load • Suitable for any size supply hose • Best way for large-diameter hose • Advantage • Disadvantage Courtesy of Sam Goldwater. (Continued) Firefighter I

  26. 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 Firefighter I

  27. Finishes for Forward Lays • Designed to facilitate making hydrant connection • Not as elaborate as finishes for reverse lays (Continued) Firefighter I

  28. 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 Firefighter I

  29. 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) Firefighter I

  30. Finishes for Reverse Lays • Reverse horseshoe finish (Continued) Firefighter I

  31. 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 (Continued) Firefighter I

  32. Finishes for Reverse Lays Firefighter I

  33. 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 50-250 feet (15-75 m) • Can be carried in several places Firefighter I

  34. 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 Firefighter I

  35. 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 Firefighter I

  36. 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 Firefighter I

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

  38. 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 Firefighter I

  39. Forward Lay (Continued) Firefighter I

  40. 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) Firefighter I

  41. Forward Lay • Advantages • Disadvantages • Information for firefighter at hydrant • Making hydrant connection • Using four-way hydrant valves Firefighter I

  42. Reverse Lay (Continued) Firefighter I

  43. 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) Firefighter I

  44. 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) Firefighter I

  45. 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) Firefighter I

  46. 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) Firefighter I

  47. Reverse Lay • Making hydrant connections with soft intake hose • Making hydrant connections with hard intake hose Firefighter I

  48. Split Lay (Continued) Firefighter I

  49. 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 Firefighter I

  50. Practical Exercises • Firefighter shall: • Identify, select, and demonstrate the use of the following nozzles: • Fog Nozzle (1 ¾’’ & 2 ½’’ ) • Smooth Bore Nozzle • Deck Gun • Blitzfire • Firefighter shall: • Demonstrate all hand hose lays • Firefighter shall: • Demonstrate all hydrant to fire apparatus hose connections
