3. Objectives Identify various sizes of fire hose Identify construction features of hose and couplings Identify difference between forward and reverse and split lays Identify hose loads

4. Woven Jacket Hose Our attack hose Can be single or double jacketed Can be lined or unlined Lined hose reduces friction loss 1-6” sizes

5. Rubber Covered Construction Braided, rubber covered “through-the-weave” and three-ply Always rubber, cloth, rubber Booster hose is of this type ¾ and 1” sizes Sometimes braided Allows hose to be open even when rolled

6. Intake hose Noncollapsible and Flexible noncollapsible 2 ½ - 6” sizes Both are rubber lined and rubber covered Noncollapsible is fabric and wire (helix) reinforced Flexible is fabric and plastic (helix) reinforced

7. Coupling Construction Casting Molten metal pored into a mold Weakest of the types Extruding Metal “pushed” through a die with lug shaped protusions Forging Strongest type Pounding metal into a forging die

8. Coupling metals Typically made from brass or aluminum alloy Brass is more resistant to corrosion, but heavier than aluminum alloy

9. Note on threaded hose couplings There are 3 piece and 5 piece Our standard coupling is 3 piece 5 piece couplings are used when needed coupling size is SMALLER than the hose

10. Forward Lay What coupling comes off the truck first? What do you need to catch the hydrant?

11. Reverse Lay What coupling comes off the truck first?

12. Split Lay Combination of the other two types, for example…

13. Hose Loads Definition – The way hose is placed in the hose bed Major types Accordion Horseshoe Flat (the type we use)

14. Hose loading guidelines Check gaskets and swivels first Keep hose sections flat Hand tighten couplings only Use “dutchman” when necessary Don’t pack hose too tightly

15. Accordion Load See page 417 Figure 12.58 Easy to load Hard on hose edges, many sharp bends in hose Not recommended for LDH

16. Horseshoe Load See page 418 Figure 12.59 Fairly easy to load Fewer sharp bends in hose Very hard to shoulder carry Problems with wide hose beds Not recommended for LDH

17. Flat Load Easiest to load Hose does have many sharp bends

18. Final Notes All hose loads and finishes are constructed essentially the same way Should review material from 419-end
