introduction 1 of 2
Introduction (1 of 2)
  • Hose is the tool used to move water.
  • Firefighters must know how to store hose on the apparatus and how to deploy it.
  • Fire hose is a flexible conduit used to move water, or other agent, from a source to the fire.
  • Couplings, adapters, and appliances are used to connect hose.
introduction 2 of 2
Introduction (2 of 2)
  • Today, many departments use National Standard Hose Threads.
  • Other departments use adapters to make connections to standard threaded couplings.
  • Adapters and appliances have been created or made lighter to make firefighting easier.
hose tools and appliances
Hose Tools and Appliances
  • Hose tools help move or operate hose lines.
  • Appliances are devices that water flows through, including adapters and connectors.
  • Tools include rope hose tools, wrenches, rollers, hose clamps, and other items.
  • Various types of valves are also used to control water flow and distribution.

Hose Loads (1 of 3)
advancing hoselines
Advancing Hoselines
  • Into structures
  • Up and down stairs
  • Using a standpipe system
  • Working hose off a ladder
establishing a water supply line
Establishing a Water Supply Line
  • Several methods exist for establishing a water supply depending on:
    • Type of water source
    • Hydrant style
    • Hose lays used
    • Pumper use at water source
extending hoselines 1 of 2
Extending Hoselines (1 of 2)
  • Firefighters should be familiar with techniques used to extend hose lines.
  • The preferred method is the use of a break-apart nozzle.
  • The other method is the use of a hose clamp.
    • Use the clamp carefully and cautiously.
replacing sections of burst line
Replacing Sections of Burst Line
  • Bursting of a hose section is very dangerous.
    • It can cause personal injury and additional property damage.
  • Hose line must be shut down to remove the section replaced.
hose lay procedures
Hose Lay Procedures
  • Supply lines and the hose beds on apparatus are designed to use one of three lays.
    • Forward lay
    • Reverse lay
    • Split lay
deploying master stream devices 1 of 6
Deploying Master Stream Devices (1 of 6)
  • Water applicators are capable of flowing over 350 gallons of water per minute.
  • A wagon pipe is a permanently mounted stream device.
  • A deluge set is not permanently mounted.
  • A monitor type device is a permanently mounted master stream device with a prepiped waterway on an aerial ladder or platform.
deploying master stream devices 2 of 6
Deploying Master Stream Devices (2 of 6)
  • A ladder pipe is a non-permanently mounted device needing a hose line.
  • Master stream devices are rigged and then charged.
  • For every foot of vertical reach needed, the device is moved one foot away. (solid stream tip)
deploying master stream devices 3 of 6
Deploying Master Stream Devices (3 of 6)
  • For horizontal reach, each pound of pressure equals 1 foot of reach.
    • Maximum reach is usually 3 floors.
  • A wagon pipe is a permanently mounted device.
  • The monitor pipe has a direct discharge.
  • Deluge set on top of an engine may be prepiped.
deploying master stream devices 4 of 6
Deploying Master Stream Devices (4 of 6)
  • When using a deluge on the ground, intakes should be facing the fire building.
  • A ladder pipe needs a hose line for rigging it up a ladder and another for supply.
summary
Summary
  • Fire hose, adapters, and appliances allow firefighters to move water.
  • It is important to know how to use the various appliances and tools.
  • Appliances and tools provide firefighters greater abilities to facilitate fire suppression.
  • Proper techniques of connecting, advancing, and operating tools must be understood.
