Chapther 12 Flashcards
Who must be notified of a water loss situation?
What should the engine officer do in this situation?
The I.C. all units operating on the fire floor and floors above.
He shall ensure the fire is confined by closing a door and/or moving all members to a safe area of refuge if necessary.
(Engine Ops Chap 12 Sec 2.1)
When do kinks constitute a water loss?
What shall be done when this is recognized by any member?
Kinks constitute a water loss when they are severe enough to reduce the extinguishment capabilities of a hose line.
“Urgent” message shall be transmitted via handie talkie.
(Engine Ops Chap 12 Sec 2.1)
Who is responsible for eliminating kinks?
Engine officer calls for additional pressure, ECC responds that sufficient pressure is being supplied, what will show that there are kinks in the line?
Who must initiate action to correct kinks?
All members operating engines and ladders included.
(Engine Ops Chap 12 Sec 2.4)
The outlet flow meter will show a reduction in flow.
(Engine Ops Chap12 Sec 2.4)
Engine Officer
(Engine Ops Chap 12 Sec 2.6)
Who besides the 1st due control man should address a water loss situation?
Who should be notified when the water loss problem has been corrected?
The 2nd due Engine aka The Water Resource Unit if at the scene.
(Engine Ops Chap 12 Sec 2.6)
The I.C. all units operating of the fire floor and floors above.
(Engine Ops Chap 12 Sec 2.7)
When is a burst length considered to be a water loss?
Engine officer reports little or no water, ECC reports adequate pressure, what will the flow meter and pump RPM’s show?
When it is severe enough to reduce the extinguishment capabilities of the hose line.
(Engine Ops Chap 12 Sec 3.1)
Increased flow showing on outlet flow meter with RPM’s increasing automatically.
(Engine Ops Chap 12 Sec 3.2)
True or False
Once a burst length is confirmed an “Urgent” message shall be transmitted
Who must be notified?
Who must take immediate action to correct this problem?
True
I.C. all units operating on fire floor and floor(s) above
The Engine Officer
(Engine Ops Chap 12 Sec 3.3)
What are all engines required to carry in case of a burst length or short stretch?
Where is it to be kept?
What can be used to replace a burst length or added to a short stretch?
Who will the Engine officer send to obtain the appropriate replacement lengths
An extra length of 1 3/4 hose rolled or folded with a controlling nozzle
An easily accessible location
The extra length of 1 3/4 or one of the 2 1/2 hose folds used for standpipe ops
Any member
(Engine Ops Chap 12 Sec 3.4)
A burst length problem can be corrected in two ways either by adding a length of hose to replace the burst length or eliminating that length and reconnecting the existing lengths if enough hose is available, when can this be done?
This shall only be accomplished upon Engine officer’s orders, after the fire has been confined by closing a door and/or members have been moved to a safe area of refuge
(Engine Ops Chap 12 Sec 3.5)
What is line pressure and what is it determined by?
Line pressure is the pressure necessary to obtain the correct water flow. Line pressure is determined by the size+number of lengths+nozzle pressure and elevation.
(Engine Ops Chap 12 Sec 3.6 table)
In a short stretch water shutdown in the line is required when adding hose to the _________
Of the stretch?
If it is a standpipe operation where will the shut down of the line take place?
ECC or other members notify Officer of all connections being complete, do they automatically start water?
Back of the stretch with either 1 3/4 or 2 1/2
Floor outlet
No on orders of the Engine officer
(Engine Ops Chap 12 Sec 4.1)
When adding 1 3/4 length to the front of the line what is brought to the front of the line?
The tip is removed from which nozzle?
The extra length is added to where?
How do you charge the new lead length?
The original nozzle is acting as what?
Water is shut down at the original nozzle but not where?
In a non fire proof MD without a well hole how may sufficient hose be found
A length of 1 3/4 with the nozzle attached
The original
Connect female butt of extra hose to shut off of original
By opening the shut off from the original nozzle
An inline gate
The pumper
(Engine Ops Chap 12 Sec 4.3)
By raising the already charged hose over the newel post onto the railing
(Engine Ops Chap 12 Sec 4.4)
When adding a length of 2 1/2 to the front of a stretch what is brought to the front of the line and and attached?
True or False
There will be a slight increase in water flow after the additional length is added?
1 1/2 “ x 2 1/2” increaser should be attached to the original nozzle after the tip is removed. This increaser should be carried in the standpipe kit attached to the extra 2 1/2” nozzle for easy access.
(Engine Ops Chap 12 Sec 4.5 +4.7)
False, a slight reduction in water flow due to the friction loss of the additional fitting and hose.
(Engine Ops Chap 12 Sec 4.5)
