The construction features of fire hose
included on threaded couplings include shank, lugs, and higbee cut and indicator.
is the point of attachment to the hose.
assist in tightening and loosing connection
i. Males couplings have lungs on shanks while female lugs are on the swivel
Higbee cut and indicator
i. Higbee cut: special threaded design where the beginning of the thread is cut to help the coupling thread and eliminate crossthreading.
ii. Higbee indicator: an indention on the lugs marking where the higbee cuts begin.
Storz-type coupling
are sexless meaning identical couplings, connected with a one-third quarter turn.
What are the four methods of coupling?
1. Foot tilt method
2. Over-the-hip method
3. Knee-press method
4. Two-fire fighter method
Coupling method: foot tilt
i. Place one foot behind the male coupling.
ii. Apply pressure to tilt it upward.
iii. Bring the couplings together and turn the swivel completely onto the male end and align the flat sides of hose in same place.
Coupling method: Over-the-hip
i. Bring the female coupling over the hip.
ii. Attach the male coupling while holding the hose in place using the hip.
Coupling method: Knee-press
i. Stand male coupling on end
ii. Place the female coupling onto the male and place a knee onto the hose above the female coupling.
iii. Knee thigh in vertical plane with coupling and apply body weight to connections.
Coupling method: Two-fire fighter
i. One firefighter holds the male coupling with both hands against the upper thigh.
ii. The firefighter with the male end looks away to help prevent from working against each other.
iii. The second firefighter brings the female coupling to the male coupling and completes the connections.
What are the two methods of uncoupling?
knee-press method, and two-fire fighter stiff-arm method.
Uncoupling method: Knee-press
i. Stand male coupling on end
ii. Place the female coupling onto the male and place a knee onto the hose above the female coupling.
iii. Keep thigh in vertical plane with coupling and body weight to connection.
Uncoupling method: Two-fire fighter stiff arm
i. Both firefighters hold each coupling and press toward the other.
ii. Keeping their arms stiff and using their weight, they turn each coupling to loosen the connection.
Hose load term: Front
towards the front of the apparatus.
Hose load term: Rear
towards the rear of the apparatus.
Hose load term: Dutchman
is a short fold or reverse bend in a hose load, or simply the direction change in a hose and the location of the coupling.
» Forward Lay
is hose lay from the water source to the fire scene. It has an advantage with having the pumper at the scene. Primarily used at areas with hydrants which requires the female coupling to be the first coupling off.
» Reverse Lay
is where hose is lay from the fire scene to the water source. This requires the male coupling to come off first.
Some hose loading factors
a. Check swivel and gaskets before connecting couplings.
b. Keep flat sides in the same plane (lug position not important).
c. Donot use spanner to tighten coupling just hand tight couplings.
d. Remove wrinkles from inside the bends.
e. Use "Dutchman" where necessary.
f. Donot pack hose to tight as this can cause excess pressure on hose, cause couplings to snag when pulled out. It should be loosen enough to place hand between the folds.
The three main hose rolls
are straight roll, donut rose, and twin donut.
Straight roll
is used for storage, carrying hose to quarters for washing, and loading hose on apparatus, etc.
Accomplish by:
Step one: rolling the hose at the male end to protect threads and roll hose from male end to female.
Donut roll
used for situations when the hose is going to be deploy from the roll for use, it allows for both ends to be available quickly, is unrolled quickly, and is less likely to spiral when unrolled.
» To accomplish donut:
Step one: roll lay the hose in a straight line
Step two: start rolling five feet off center closer to male coupling
Step three: and roll towards female.
Twin donut roll
is a compact roll transportable for special application, such as high rise situations, both ends are available.
» To accomplish twin donut:
Step one: Place the male and female couplings together and lay the hose flat forming two parallel lines
Step two: Fold the loop end over and on to the two lines
Step three: Roll both lines simultaneously toward the couplings
Demonstrate hose and hose coupling cleaning, maintenance, and inspection procedures.
To clean use soapy water to free swivels, and brush to remove dirt and tar from threads. Do not oil
Maintenance really only includes doing your best to preserve and prevent damage. Avoid excessive dropping and do not allow vehicles to drive over hose.
Inspection procedures include basic check of damage to couplings, the round shape, and making sure the threads properly tighten.
Demonstrate procedures for replacing a burst section of hose using the kink or clamp method.
KEY THING TO REMEMBER: Use two hoseline to replace one burst section due to the fact that hoselines stretch under pressure. SHUT OFF water supply with clamp at least three feet behind coupling of damage section. Replace with two additional lengths and straighten hose as much as possible. Slowly release clamp and you are back in business.
Identify procedures for advancing an attack lines into a structure as a team.
a. All firefighters should be on the same side of the hose.
b. Feel the door for before entering.
c. Bleed air out before entering.
d. Stay low and out of doorway when opening the door.
Identify procedure for advancing up a ladder.
a. Dry hose can be simply draped cross chest with nozzle over the shoulder and toward the rear with both hands on the rungs.
b. Charge hoseline
i. Position firefighter on a ladder within reach of each other with each secured to ladder.
ii. Firefighters on the ground extend the hoseline up to the firefighter lowest on the ladder.
iii. The hose is than pushed from firefighter to firefighter.
Identify hose appliances and tools.
Hose appliances allow water to flow through them, while hose tools do not.
Hose appliance includes
valves, Siamese appliances, water thief appliances, gated wye appliance, fittings and reducers.
Siamese appliance
combines two hose into one. It will have two female ends and one male. Has a clapper valve so that even with one hose it would still work.
Water thief appliance
is a variation of wye appliance except it has more outlets.
divides one hose into 2 or more. Most common is one 2 and half female and two 1 and half male outlets.
Hose tools include
include hose roller, hose jacket, hose clamp, wrenches, mallet, ramp, straps, etc.
Identify and demonstrate the procedures for conducting annual fire hose service test
Lay hose no longer than 300 feet, charge at 250psi for 5 minutes and watch. Check for slipped or loose couplings.
