Chapters 9-12 Flashcards
In order to have a safe and successful operation when using water fog for an indirect attack there must be what?
Extremely high heat, no ventilation, no occupants
Who began to Pioneer the use of water fog as an extinguishing agent?
Lloyd Layman
Next to the nozzle what is the most important of the water delivery appliances in a standpipe kit
Standpipe inline pressure gauge
What is the primary firefighting unit of all fire departments?
The engine company
Where most firefighters be positioned in order to efficiently Advance a 2.5 in handline?
At the corners, top bottom and middle of the stairs and on the floor below
The nozzle team operating the 2.5 inch handline must consist of what
At least two firefighters but preferably three or more and a company officer
At a typical residential high-rise fire, with the common public hallway, the second hand line can and in most cases should be stretched where?
Directly behind the first attack line up to the point of entry, typically the fire department door
Can fire attack be employed using the primary line and the backup lines simultaneously?
Yes
What type of stream has a greater chance of penetrating the wind currents typical of high-rise operations and thus allow for solid droplets of water to reach burning solid fuels?
Solid stream
What is a “campaign” fire ground operation?
Two engine companies for the initial attack, two engine companies to relieve them, and two additional engine companies located in staging for relief
What is the first of several engine company fireground responsibilities?
Water supply
What are the types of standpipe systems?
Wet and dry systems, automatic or non
What type of standpipe systems are most commonly found in most modern high-rise and standpipe equipped buildings?
Fully automatic wet standpipe systems
The standpipe system that requires immediate support from fire department Pumpers in order to establish and maintain a water supply to the standpipe system
Non-automatic dry system
In the event that one of the two Clapper valves is broken which connection should be made first?
The broken Clapper valve should be hooked up first
When supplying an FDC where should the pumper be located?
As close to the FDC as possible, preferably within 50 ft
Which discharge Outlets should be used to supply the standpipe system?
Discharges as remote as possible from the pump panel of the pumper apparatus as well as the engineer and any other member operating in this area
What is the recommended overall primary water supply for a high-rise or standpipe equipped building
Two separate Pumpers tandem pumping through at least two pumps and then into the building system
What is a good rule of thumb for supplying a standpipe system?
One standard two-stage Pumper for every 10 flights of vertical elevation
Where should the second do engine company be positioned
At the hydrant pumping to the First new engine
Where should the second do engine company be positioned?
At the hydrant pumping the first Pumper
What should the third and fourth new engine companies do on arrival?
Establish and maintain a separate secondary water supply on a different hydrant
The supply method that involves using an interior standpipe hose valve Outlet to backfill the stand pipe system riser
Bypassing the FDC
What is the minimum size supply line for a stand pipe system when bypassing the FDC
3 in
When is it not possible to bypass the FDC?
When the standpipe is equipped with a PRV.
What is the friction loss in the standpipe system itself
25 psi
What is a fast and relatively accurate formula and A good rule of thumb for figuring friction loss in a high-rise event
100 + 5psi per floor for every floor up to the fire floor
