Hard suction and/or soft suction Also know as soft or hard sleeve

Identify the types of fire hose damages and their preventions. 2-7.3

Mechanical Damage Worn spots Rips Abrasions Cracked inner lining
Crushed or damaged couplings

Mechanical Damage Prevention
Avoid laying or pulling hoses over sharp corners. Provide warning devices to divert traffic. Prevent vehicles from running over hoses and couplings. Close nozzles slowly. Change the bends in the hose when re-bedding. Provide chaffing blocks Avoid excessive pump pressures on hose lines.

Thermal Damage Charring Melting Drying out of rubber lining

Thermal Damage Prevention
Protect hose excessive heat/fire. Do not allow hose to remain in heated area after drying. Use a moderate temperature for drying Keep outer jacket dry. Run water through hose that has not been used for some time. Avoid drying hose on hot pavement and/or direct sunlight Prevent hose from being laid to close or form coming in contact with vehicle exhaust. Use hose bed covers to shield hose from elements. Freezing temperatures(snow and ice) also damage hose.

Mildew/Mold Damage(Organic)
Decay Mold Mildew Deterioration

Chemical Damage Exposure to petroleum products Exposure to run off
Exposure to alkali and acids Exposure to chemical materials and vapors

Organic Damage Prevention
All wet hose should be removed from apparatus, and replaced with good, dry hose. Hose should be removed, inspected, swept, and reloaded every thirty days if not used. Exercise hose every thirty days. Run water through all hose every 90 days.

Chemical Damage Prevention
Thoroughly scrub all traces of acid contacts with baking soda and water. Periodically remove hose from the apparatus, wash it, and run water through it. Properly test hose if any suspicion of damage. Avoid laying hose in the gutter. Properly dispose of hose that has been exposed to hazardous materials and cannot be decontaminated.

General Care and Maintenance of Hose
Brush of loose dirt and such broom Washing hose Several different ways Wash with warm water and a mild soap Commercial or generic hose washers Rinse hose with water in different are than washed

Drying hose Rubber jacket hose can be re-bedded wet, woven jacket and such cannot! Use commercial hose dryer Hang in hose tower

Storing Should be stored rolled On acceptable racks Well ventilated room

Identify the construction features of fire hose couplings. 2-7.4

Materials Brass alloy Aluminum alloy Magnesium

Types of Couplings Threaded Storz (pronounced stortz) Others
Quarter turn Oil filled rocker jug Snap or Jones

Manufacturing Techniques of Couplings
Drop forged: hardest Extruded: somewhat weaker than drop forged Cast: weakest

Threaded Couplings Three piece Five piece Used on intake hoses
Usually found on appliances and adapter fittings

Parts of Couplings Shank Swivel Higbee cut and Indicator Lugs

Shank Also called tailpiece, bowl, or shell
Male has rocker lugs or pins Female shank is smooth

Swivel Contains female threads Permits coupling without turning hose
Has rockers/lugs/pins Shanks is smooth

Higbee Cut and Indicator
On both couplings Special type thread designed to provide a positive connection between couplings Indicator is a shallow indention of one of the lugs Helps eliminate cross threading

Lugs Pin Rocker Recessed Not to common anymore, usually older hose
Tends to snag when hose is dragged Rocker Rounded to prevent hang ups Found on all modern hose Usually two to three lugs Recessed Usually found on booster lines

Storz Couplings “Sexless” Coupled by a 1/3 turn
No distinct male and/or female coupling Coupled by a 1/3 turn Newer ones have locking components to prevent water pressure spinning of hose Grooved lugs Insert rings built into the swivel

Care of Fire Hose Couplings
All parts of couplings are susceptible to damage Male threads can be damaged if not protected Female threads are not exposed, but the swivel is subject to bending damage

Avoid dropping and/or dragging Do not permit vehicles to ride over them Examine couplings when washing hose Clean threads to remove tar, gravel, and oil Inspect gasket, and replace if cracked or creased Remove the gasket and twist the swivel in warm, soapy water.

Swivel gaskets and expansion gaskets should be tested after use and/or cleaning of the hose. Swivel gasket- used to make the connection water tight. Expansion Ring Gasket- used at the end of the hose where it is expanded into the shank of the coupling. See pictures. Pinch the gasket between together between the thumb and index finger. This usually show any defects or signs of determination.

Identify the uses of hose rolls. 2-7.5

Straight Roll Placed in storage Returned to quarters for washing
Loaded back on the apparatus

Donut Roll Situations when it is going to be deployed directly from a roll for use. Used when both ends to be together.

Twin Donut Roll Used for a compartment roll which may be transported and used for high-rise operations. Self-Locking Twin Donut Same as above, except a carrying strap is formed.

Forward and Reverse Hose Lays
Identify the difference between a forward and a reverse hose lay. 2-7.6

Hose Lays Forward Lay Reverse Lay Split Lay

Forward Hose Lay Also called a straight lay.
From the water source to the scene. Laid form the water source to the fire.(tagging the hydrant) Hose bed set up with female coupling coming off first. Primary advantage is that pumper is at fire scene so hoses, tools, etc. can easily and quickly e obtained. Operator also visual contact with crew and react better to changing conditions.

Forward Hose Lay Disadvantage
Longs lays are near impossible and smaller diameter supply lines (21/2 and 3 inch) may need a second pumper to boost pressure. One firefighter must be left at the hydrant to secure the water supply.

Reverse Hose Lays Hose is laid from the fire scene to the water source. The pumper must first stop at the scene, do a size up and drop the supply line. Should be loaded with the male coupling coming off first. Usually done with relay operations and/or drafting operations.

Reverse Hose Lays Disadvantages
Essential tools and equipment are located far from the fire scene This is also done when the initial engine attacks the fire and the second engine lays a supply to the initial attack engine.

Split Lays Two lines laid forward Two lines laid reverse
Reverse lay followed by a forward lay Two lines laid forward followed by one or two lines laid reverse Two lines laid reverse followed by the one or two lines laid forward.

Precautions while Advancing Hose Lines
Identify precautions to be followed while advancing hose lines to a fire. 2-7.7

Advancing Hose Lines Safety!!!!!!!!! Be alert for potential dangers especially of backdrafts, flashover, and potential or occurring building collapse. All firefighters should be on the same side of the hose. Check door for heat!, before you open it. Bleed excess air from hose line and check nozzle pattern before entering. STAY LOW! Avoid blocking ventilation openings such as doors and windows.

Some General Guidelines.
Loading Hose Some General Guidelines.

Hose Loading Check gaskets and swivels before connecting any hose.
When two sections are connected keep flat sides on same plane. Hand tighten connections. When the hose is bent to load, smooth the bend. Avoid loading hose so that the coupling “turns”. Use a “dutchmen” to prevent this. For LDH load all couplings in the front of the bed. Do not pack hose tightly.

Identify three (3) types of hose rolls. 2-7.8

Straight Roll Lay hose out straight and flat on a clean surface. Roll male coupling over onto hose to start the roll. Form a coil that is open enough to allow the fingers to be inserted. Continue rolling the coupling over onto the hose, forming an even roll. As the roll increases in size, keep edges aligned. Lay roll flat on ground when completed. Using a foot, tamp any protruding coils down into the roll.

Donut Roll 2 Methods 2-7.8.2 Method One
Lay section of hose flat and in a straight line. Start the roll from a point 5 to 6 feet off center towards the male coupling. Roll towards female end. Leave sufficient space at center loop to insert the hand for carrying. Near the completion of the roll, the male coupling is enclosed within the roll as the hose is rolled over it. Check to make sure the male coupling is inside the roll with the female coupling about 3 feet ahead of it.

Donut Roll 2 Methods Method 2 Grasp coupling and carry to other end.
Check to make sure the looped section laying flat, straight, and w/o twists. Face coupling ends and start rolling 2 ½ feet from bend towards male coupling. Pull the female side back to relieve tension. As roll approaches the male coupling, lay the roll flat on the ground and bring the female end around the male coupling to complete the roll.

Twin Donut Roll 2-7.8.3 Place the male and female couplings together.
Lay the hose flat w/o twisting, to form two parallel lines from the loop end to the couplings. Fold the loop end over and upon the two lines to start the roll. Continue to roll both lines simultaneously towards the coupling ends, forming a twin roll with a decreased diameter.

Self-Locking Twin Donut Roll 2-7.8.4
Place the male and female couplings together. Lay the hose flat, w/o twisting, to form parallel lines from the loop end to the couplings. Move one side of the hose up over 2 ½ to 3 feet to the opposite side w/o turning. Adjust the size of this shoulder loop to the proper length for carrying. Facing the coupling ends, bring the back side of the loop forward toward the couplings, and place it on top of where the hose crosses forming a loop on each side w/o twist.

Self-Locking Twin Donut Roll 2-7.8.4
Start rolling towards the opposite ends, forming two rolls side by side. When rolls are completed, allow the couplings to lie across the top of each roll, and adjust the loops, one short and one long, by pulling only one side of the loop through. Place the long loop through the short loop, just behind the couplings, and tighten snugly forming a shoulder sling.

Coupling and Uncoupling Procedures
Identify different types of coupling and uncoupling techniques. 2-7.9

Coupling Hoses Foot Tilt Method 2-7.9.1
Stand facing the two couplings so that one foot is near the male end. Place the foot directly on the hose behind the male coupling and apply pressure to tilt it upward. Position feet apart apart for balance. Grasp the female end by placing one behind the coupling and the other hand on the coupling swivel. Bring the two couplings together and turn the swivel clockwise with the thumb to make the connection.

Coupling Hoses Female Coupling 2-7.9.2
Grasp female coupling with both hands. Bring both couplings together. Align them using the Higbee indicator. Turn the female coupling counterclockwise until a click is heard. Turn the female coupling clockwise until tightened.

Uncoupling Hose 2-7.9.3 Knee Press Method
Grasp the hose behind the female coupling. Stand the male coupling on end. Set feet well apart for balance. Place on knee upon the hose and shank of the female coupling. Snap the swivel quickly in a counterclockwise direction as body weight is applied to loosen the connection.

Uncoupling Hose 2-7.9.4 2 Firefighter Stiff Arm Method
Take a firm two-handed grip on your respective coupling and press the coupling toward the other firefighter, thereby compressing the gasket in the coupling. Keep arms stiff, and use the weight of both bodies to turn each hose coupling counterclockwise, thus loosening the connection.

Identify different types of hose carries. 2-7.10

Hose Carries Shoulder Loads 2-7.10.1 (from flat or horseshoe loads)
Attach nozzle to end of hose. Position carrier at tailboard facing in the direction of travel. Place the initial fold of hose over the carrier’s shoulder so that the nozzle can be carried chest high. Bring the hose from behind over the shoulder so the first fold ends at the knee and the rear fold ends at the back of the knee.

Hose Carries Complete the above procedure for each carrier until the desired length of hose is loaded. Uncouple the hose from the bed when desired length is loaded. Hand the coupling to the last carrier.

Hose Carries Shoulder Loads 2-7.10.1(from flat or accordion loads)
Facing the hose bed, grasp the nozzle and the number of folds needed to make the desired length. Pull the folds about one-third of the way out of the bed. Twist the folds into an upright position. Turn and pivot onto the folds placing them on top of the shoulder. Make sure the hose is flat with the nozzle and/or coupling in front of the body.

Hose Carries Hose Carry/Drag 2-7.10.2
Stand along side the hoseline and pick up the nozzle or coupling. Place the hoseline over your shoulder with the coupling (nozzle) in front, rest it on chest. Hold the coupling in place while pulling with your shoulder, arm, and legs dragging hose to desired location.

Hose Carries Hose Drag/Carry 2-7.10.3
Stand alongside hoseline and pick up the nozzle or coupling. Walk 25 feet. Place the hoseline over your shoulder with the coupling in front resting it on your chest. Pick up hose with other hand. Hold coupling in place while pulling with your shoulders, arms, and legs dragging the hose to the desired location.

Identify the different types of loading hose loads or finishes.

Accordion Load Lay the first length of hose in the bed on edge against the partition with the coupling at the rear of the bed. At the front of the bed, fold the hose back on itself, and lay it back to the rear next to the first length. At the rear of the hose bed, fold the hose so that the bend is even with the rear edge of the bed, and then lay the hose back to the front. Continue laying hose folds across the bed staggering the fold so that every other bend is approximately two inches shorter than the edge of the bed. When another tier must be started, angle the hose upward to the front of the bed.

Horseshoe Load Place the female coupling in a front corner of the hose bed with the hose on edge and against the wall Make a fold at the rear even with the edge of the hose bed Lay the hose to the front and then around the perimeter of the bed so that it comes back to the rear along the opposite side Make a fold at the rear in the same manner as Step #2. Lay the hose back around the perimeter of the hose bed inside the first length of hose.

2-7.16

Definitions Appliance- A device other than a coupling that is used with the hose and through which water must pass Tool- A device that makes handling of hose and appliances easier. Some devices help protect hose against unnecessary wear and damage.

Appliances Valve Devices
Wye Appliance- divides one hose line into two or more lines. Wye appliances are gated and may be controlled at the gate. Siamese Appliance- takes two or more hose lines and makes one hoseline or device. May or may not have a clapper. Usually used to overcome problems encountered due to friction loss in hose lays which need to carry a large flow or cover a long distance. Also used to supply ladder pipes that do not have permanent waterway.

Ball-used in pumper discharges and gated wyes. They are open when in line with the hose. Also used in the pumps themselves. Gate-used to control the flow of water from a hydrant Butterfly-used on LDH intakes. A quarter turn handle Clapper-used in Siamese's to allow only one intake hose to be connected and charged before additional hoses are added. It is flat hinged disk.

Water Thief- A variation of the wye. It has one (1) 2 ½ inch inlet and one (1) 2 ½ inch outlet and two (2) 1 ¾ outlets. Hydrant Valves- Used when the hose lay id made from from the water supply source to the fire scene. It allows for the initial supply to be charged and by using valves allows other lines to be connected w/o shutting down the hydrant.

Fittings Adapter Reducer Double Male Double Female Elbows
Hose Caps- male couplings- 2 ½ “ discharge on pump panel Hose Plugs- female couplings- 2 ½” intakes on pump panel

Intake Device Hose strainers Two types
Barrel Low level high volume Most commonly used in drafting operations

Tools Hoist (hose roller) Jacket Clamp
Spanner, hydrant wrench, rubber mallet Bridge Chaffing block Strap, rope, chain

Hoist Also called hose roller
Hose can be damaged when dragged over sharp corners or edges The roller consists of a metal frame with a roller in the middle that is either secured with rope or a “c”-clamp

Hose Jacket Placed over a section of hose that bursts or develops an aneurysm (bulge) It is applied at the point of rupture on the hose line Usually comes in 2 ½” and 3” sizes It allows the line to be flowed at full pressures It can also be used to connect hose with mismatched or damaged screwed couplings

Hose Clamp Used to stop the flow of water
To prevent hose in the hose bed to be charged To allow replacement for burst sections To allow extension of a hoseline w/o shutting down water supply To allow advancement of a charged line upstairs 3 types Screw down Press down Hydraulic press Keep at least 20 feet behind apparatus Apply approx. 5 feet from the incoming water side Stand to one side when applying or releasing the press down hose clamp

Spanner, Hydrant Wrench, Rubber Mallet
For tightening and loosing hose connections It has a wedge for prying Openings that fit gas meters Slot for pulling nails Flat surface for hammering Hydrant Wrench Used to open a hydrant Rubber Mallet Used to strike lugs

Hose Bridge/Ramps Helps to prevent injuries to hoses where they cross streets where vehicular traffic cannot be diverted Also used over small spills to protect hoses

Chaffing Blocks Used to prevent hoses from being abraded from vibrating on cement, asphalt, curbs, etc. during operations Can be made from wood, leather, or old truck tires

Hose Straps/Ropes/Chains
Also called rope hose tool Used to carry and/or pull fire hose Also provides a means to handle and secure pressurized hoses Especially to ladders

Advancing Uncharged Hose Lines
Identify the procedures for advancing uncharged attack lines from a pumper. 2-7.17

CAUTION! An uncharged hose line should never be advanced into a fire or through a door that is hot to the touch. The line should be charged and the nozzle person should bleed the air from the nozzle and select the proper pattern before ever entering the fire area.

Into a Structure Select hose line, properly remove from rig, and deploy toward entrance Nozzle person and back up person on same side of hose Nozzle person at nozzle and back up person a few feet back, if available the third person is midway between end of first section of hose and coupling Fell the door for heat. This can give an indication of extreme heat build up, signifying the potential for a flashover or backdraft Stay low and do not block ventilation openings

Up a Ladder to Second Floor Landing 2-7.17.2
Select hose line, properly remove from rig, and deploy to base of ladder If carrying a shoulder load lay it to the left side of the ladder Nozzle person takes nozzle and pulls it under left arm pit, across the chest and over right shoulder, so nozzle rests in the small of the back Nozzle person, with both hands free, climbs the ladder to the second floor landing Nozzle person steps off ladder onto the building, second firefighter drapes large loop of hose over his/her shoulder and starts up the ladder.

Up a Ladder to Second Floor Landing 2-7.17.2
The above process continues until an adequate amount of hose has been advanced

Up an Inside Stairway to an Upper Floor 2-7.17.3
Select hose line, properly remove from rig, and deploy to the base of the stairs Advance up stairway feeding hose off of a shoulder load if used Lay the hose on the stairs against the outside wall to avoid sharp kinks and bends Once desired landing is reached, excess hose can be flaked up the stairs toward the floor, above the fire and looped back down (use extreme caution when placing FF’s above the fire floor w/o a charged line) When the hose line is in place, nozzle person prepares to advance the line

If possible FF’s should be placed at every turn or point of resistance to assist deployment

Down an Inside Stairway to a Lower Floor 2-7.17.5
Select hose line, properly remove from rig, and deploy to the base of the stairs Advance down stairway feeding hose off of a shoulder load if used Lay the hose on the stairs against the outside wall to avoid sharp kinks and bends Have all hose in place when reaching fire floor When hose line is in place, nozzle person has line charged, bleeds off air, checks pattern and prepares to advance line If possible FF’s should be placed at every turn or point of resistance to assist deployment

Down an Outside Stairway to a Lower Floor 2-7.17.6
See last slide

To an Upper Floor by Hoisting 2-7.17.7
See other slides, in addition Lower rope of appropriate length from intended destination Have a hose roller, if available Fold nozzle end of hose line back over the rest of the hose until an overlap of four or five feet is formed Tie a clove hitch w/ an overhand safety around the tip of the nozzle and the hose it is folded against Place a half hitch on the doubled hose about 12 inches from the loop end

Operating Charged Attack Line from a Ground Ladder
2-7.19

CAUTION OPERATING A HOSE LINE FROM A GROUND LADDER RREQUIRES THE LADDER TO BE SECURELY TIED AND HEELED.

Operating a Charged Hose Line from a Ground Ladder
Hose brought to base of ladder where it is charged and bled Nozzle person and FF’s space themselves on the ladder within reach of each other Each FF ties into the ladder with a leg lock of ladder belt Using both hands the hose line is then pushed upward from FF to FF The nozzle person projects the nozzle through the ladder rungs allowing for approx. I foot to be extended beyond the rungs at the level, and secures ladder w/ straps or belt

Operating a Charged Hose Line from a Ground Ladder
Secure the hose w/ ladder belt or rope hose tool several rungs below the one on the nozzle person is standing on Once the hoseline, nozzle, and all FF’s are tied in and secure the nozzle can be opened slowly
