NFPA 14 also requires that a water supply for a Class II system be capable of delivering 100gpm for 30 minutes.
The minimum outlet pressure for Class I and Class II outlets is now ______ psi after a modification to NFPA 14 in 1993 changing it from the 65 psi.
The minimum outlet pressure for Class I and Class II outlets is now 100psi after a modification to NFPA 14 in 1993 changing it from the 65 psi.
When two or more sources feed a wet standpipe system, Which source will the standpipe system use to provide the water?
When two or more sources feed a wet standpipe system, the source providing the highest pressure will be the one that provides the water.
A ____________keeps possible contaminated water from entering the potable water system.
A check-valve keeps possible contaminated water from entering the potable water system.
*When available, a_________________almost always is used as the primary water source.
*When available, a public waterworks system almost always is used as the primary water source.
Gravity systems
They are mounted on the ground when supplying one and two story buildings or mounted above ground on taller structures. They may hold as much as 100,000 gallons of water.

how do Pressure tanks differ from gravity tanks?


where are they usually found?

Pressure tanks differ from gravity tanks because the top 1/3 of the tank contains air under pressure.




These are generally found only on smaller systems and supply house lines with water for initial attack by the occupants.

. FDCs are required on all Class___ and Class___ systems.
. FDCs are required on all Class I and Class III systems.

As a rule, most FDCs are provided with a


________ inlet for each _______gpm of design flow rate.

As a rule, most FDCs are provided with one 2-1/2” inlet for each 250gpm of design flow rate.
**If the fire is severe, a fire department __________________ can be placed on a standpipe connection intake and additional supply lines can be hooked into the system.
**If the fire is severe, a fire department siamese appliance can be placed on a standpipe connection intake and additional supply lines can be hooked into the system.
The best arrangement for supplying a standpipe system is to have a pumper positioned within _________ feet of the standpipe siamese.
The best arrangement for supplying a standpipe system is to have a pumper positioned within 100feet of the standpipe siamese.
When utilizing standpipes, the first hose line in the building should be at least ________ feet long and of a diameter dictated by the size and intensity of the fire.
When utilizing standpipes, the first hose line in the building should be at least 150 feet long and of a diameter dictated by the size and intensity of the fire.
An equipment staging area, or “equipment pool” should be set up usually _________ floors below the fire, depending on conditions on the fire floor or other ongoing activities within the building.
An equipment staging area, or “equipment pool” should be set up usually two or more floors below the fire, depending on conditions on the fire floor or other ongoing activities within the building.

Fire tends to extend vertically because of




LAPPING. what is that?




What Types of buildings is this especially true for? and why?

Fire tends to extend vertically because of lapping, or leap-frogging from window to window. Lapping refers to fire that jumps from floor to floor through exterior windows. This is especially true in fire-resistive buildings because heat is typically forced to the exterior windows which is the weakest part of the building
is it ok to use elevators on the lower floors?
Elevators should not be used for fires on lower floors. Stairways should be used to gain entry to these type fires.
is it ok to take a quick glimpse of the fire floor from the elevator?

no nonononononononono
if using the elevator, which floor should you get off ?
Fire fighters should stop TWO floors or more below the fire and then use the stairway to the fire floor.

If the fire is located some distance down the corridor from the stairway, the initial hookup can be made on the fire floor!




is this true? what precautions would have to be made?

If the fire is located some distance down the corridor from the stairway, the initial hookup can be made on the fire floor; however, this should not be attempted unless the firefighters are certain the fire is confined to an area off the corridor or at least some distance from their point of entry to the fire floor.

The most common type of sprinkler system?




tell me a little about it

The most common type of sprinkler system is the wet-pipe system




the piping is always filled completely with water from the source to the heads

sprinkler systems


Dry-Pipe System

Dry-Pipe System . The system contains water only from the source to a control valve, known as the dry-pipe valve

Pre-Action System


-What is it?


-is it dry or wet?


-What is it controlled by?



Devised to minimize the activation time by exhausting the compressed air before the head opens.




2. This is a dry system with the addition of air exhausters




3. This is controlled by a supplemental fire detection system.




4. Pre-Action systems can be used wherever dry pipe systems can be used.

Deluge System


-What is it?


-Control of the system is where?


-What types of buildings usually have them?

Contains only water from the source to a control valve. The piping from the valve to the heads contains only room air, and the heads are open at all times.




2. Complete control of the system is provided at the valve.




3. Deluge systems usually are installed in high-hazard locations such as aircraft hangers,chemical plants, laboratories, and transformer rooms, or other areas where fire might spread rapidly.

**During an actual fire incident, a fire fighter must be assigned to the ________ and _________to ensure a continued operation of the system.**
**During an actual fire incident, a fire fighter must be assigned to the main valve and fire pump to ensure a continued operation of the system.**
What is the NFPA Standard Recommended Practice for Fire Department Operations in Properties Protected by Sprinkler and Standpipe Systems
*NFPA 13E, Recommended Practice for Fire Department Operations in Properties Protected by Sprinkler and Standpipe Systems**
A pumping pressure of ___________ psi is recommended for sprinkler systems.
A pumping pressure of 150psi is recommended for sprinkler systems.
