Objectives (1 of 4) • Identify and explain the construction of fire hose. • Demonstrate the care and maintenance of fire hose. • Identify the types of hose couplings and threads. • Demonstrate the care and maintenance of hose couplings.
Objectives (2 of 4) • Identify and explain the use of hose tools and appliances. • Demonstrate the coupling and uncoupling of fire hose. • Demonstrate the rolling, carrying, and loading of fire hose. • Demonstrate the advancing of fire hose lines, both charged and uncharged.
Objectives (3 of 4) • Demonstrate the establishment of a water supply connection. • Demonstrate the extending of hose lines. • Demonstrate the replacement of burst hose sections. • Demonstrate the procedures for laying hose lines for water supply.
Objectives (4 of 4) • Demonstrate the deployment of master stream devices. • Demonstrate the service testing of hose.
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) • 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 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 Rolls • Roll hose storage or to have it ready for use. • Several options • Straight/storage hose roll • Single-donut roll • Twin or double-donut roll
Hose Carries (1 of 2) • Drain and carry method • Shoulder loop carry • Hose/street drag

Advancing Hoselines • Into structures • Up and down stairs • Using a standpipe system • Working hose off a ladder
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) • 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 • 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 • 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) • 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) • 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) • 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) • 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 • 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.
