1. Fire Hoses, Nozzles, Portable lighting, appliances, and ladders.

2. Sizes of Hoses Fire hoses range in size from 1” to 6” in diameter
a. small diameter hose – 1” to 2”
1. used in small outdoor fires
b. medium diameter hose – 2 ½ “ to 3”
1. used to attack larger fires
c. large diameter hose – 3 ½ or more

4. Types of Hoses
Booster hose – type of attack hose usually carried on a hose reel holding 150’ or 200’ of rubber hose; limited to small outdoor fires
Forestry lines- type of attack hose small in diameter, often used for fighting wildland and ground fires; sometimes extended for hundreds of feet
Soft suction hose- type of supply hose that is a short section of large diameter hose; used to connect fire department engine directly to the large streamer outlet on a hydrant
Hard suction hose- special type of supply hose; drafts water from a static source such as a river, lake or portable drafting basin

8. Functions of Fire Hoses
Hoses are used for two main purposes
a. used to discharge water from an attack engine onto the fire
b. used to deliver water to a fire department connection that supplies a standpipe or sprinkler system inside a building

9. Uses of Hoses designed to be used as either an attack or supply hose
a. attack hose – withstands higher
pressures when subjected to
sharp surfaces, abrasions and other
potentially damaging conditions
b. supply hose – constructed to
operate at lower pressures and in
less severe operating conditions,
but must still be durable and resist-
ant to external damage

10. Nozzles, Hose Adapters, Hose Appliances
Explaining The Uses
Nozzles, Hose Adapters, Hose Appliances

13. Uses of Nozzles
Defines the pattern and form of the water discharged onto the fire
Smooth bore or adjustable nozzles can both produce a fire stream
Nozzle discharge patterns first major distinction is between a fog stream and a straight stream

15. Hoses Adapters Appliances
Connects hose couplings of the same diameter having dissimilar threads
Connects threaded couplings to Storz-type couplings
Double male and double female adaptors commonly used to perform a reverse hose lay
The conjunction of any device with a fire hose for the purpose of delivering water
Wye, water thief, Siamese connection, double-male and female adaptors, reducers, hose clamps, hose jackets and hose rollers are all examples of hose appliances

18. Connecting A Fire Hose To A Hydrant
Remove cap from outlet
Look inside hydrant for any objects that may have been thrown inside
Double check the remaining hydrant caps are snugly attached
Place hydrant wrench on the stem nut; check top of hydrant for the arrow indicating which direction to turn the nut to open the hydrant valve
Open the hydrant enough to determine there is a good flow of water and to flush any objects
Shut off the flow of water
Attach the hose or valve to the hydrant outlet

19. Coupling/Extending Fire Hoses
Analyzing Techniques
Coupling/Extending Fire Hoses
Demonstration
One set or pair of connection devices attached to a fire hose allowing hose to be interconnected to additional lengths of hose

20. Procedures for Inspection and Maintenance of Fire Hoses, Coupling and Nozzling
Common damage to hoses include mechanical causes, chemicals, heat, cold weather and mildew
Nozzles inspected on regular basis, along with all of the department equipment
Defective hoses must be marked; replace worn coupling gaskets

21. Procedures for Inspection and Maintenance of Fire Hoses, Coupling and Nozzling
Possible debris inside nozzle will affect the performance reducing flow
Any problems should be referred to a competent technician for repair

22. Illustrating Hydrant-To-Pumper Hose Connections

23. Uses For Portable Lighting
When emergency incidents happen at night
Illuminates the scene, enabling safe, efficient operations
Interior lighting essential due to heavy smoke blocking out natural
Different types of lighting equipment are used for different situations; spotlight projects a narrow concentrated beam of light and floodlights project a more diffuse light over a wide area

25. Identifying Types of Ladders
Aerial
Portable
permanently mounted and power-operated from piece of fire apparatus
1. Vary in design and function
2. Often referred to as straight- stick aerials
3. has an elevated platform apparatus
designed to be removed and used in other locations
1. straight
2. roof
3. extension
4. bangor
5. combination
6. folding
7. fresno
8. pompier

26. Ladders

27. Importance of Ground Ladder Maintenance
Must be visually inspected at least once a month and after each use
Regular maintenance of keeping the ladder in proper operating condition
Should be cleaned regularly to remove road grime and dirt build-up
Service testing required periodically evaluating the continued usefulness of a ladder during its life

28. Procedures for Carrying, Positioning and Raising Ladders
Full turnout clothing and protective equipment are essential for working
Teamwork is essential
Must always use proper lifting techniques, coordinate all movements
Fire fighter should survey area where ladder is going to be used in case ladder is placed in potentially hazardous location
Rather than risking injury, it is better to ask for help especially over uneven terrain, through gates or over snow and ice

30. Significance of Safety In Climbing Ladders
Set at proper angle for maximum load capacity and safety, dogs must be locked and the halyard tied before anyone climbs to prevent from falls occuring
To prevent slipping, another fire fighter should secure the base by footing the ladder
Ladders should have ability to accommodate weight limit of 750 lbs or the equivalent to that of one person and two firefighters

31. Review What type of ladder exponent is a halyard?
Name one importance of ground ladder maintenance?
Name two different types of hoses used for fire fighting?
Define coupling
