Can usually be described as a horizontal standpipe
Term
Ideally stretching from the pumper at fires in buildings with horizontal SPs
Definition
Should become the primary method-it is the safest
Term

Definition
Typically found in many parking garages
Term
Combination systems
Definition
Where the sprinkler system and the standpipe for manual firefighting are actually supplied by the same standpipe riser
Term
SP and sprinkler are separate, not a combination system
Definition

Decision: FDC for the stand pipe supplied first.

sprinkler and FDC  SP must be pumped into.

Term
Standpipe defined in NFPA 14;
Definition
 as an arrangement of piping, valves, hose connections located in such a manner that water can be discharged in streams through attached hose and nozzles, for the purposes of extinguishing a fire, thereby protecting a building or structure and its contents in addition to protecting occupants
Term
Water supply for standpipe system

According to NFPA 14
Definition

The pipe, fittings, and valves used for the standpipe system are rated for pressures of up to only 300

nfpa14 also recommends that the maximum pressure within the system at any point should not exceed 350 psi

Term
Valves located throughout a typical standpipe system
Definition
  • Pivs, os&y, check valves and sectional control valves control the flow of water throughout the stand pipe system 
Term
Hose connection valves
Definition
Hose connections should be unobstructed, and are required to be located not less than 3 feet or more than 5 feet above the floor
Term

pressure regulating devices

Pressure reducing valves (prvs)

Definition

In most cities, SPs, especially those in tall high rise buildings, are typically equipped with pressure regulating valves

Can be found in 2 locations: zone floor control valves for combination SP/sprinkler or at SP hose valve outlets

Term
PRVs
Definition
  • Nfpa14
  • Designed for the purpose of reducing, regulating, controlling, or restricting water pressure in order to limit SP outlet pressure
  • 3 types: pressure-rwatricting devices, Pressure-reducing valves, Pressure-control valves
Term
orifice plate
Definition
A metal disk with a restricting orifice. If used, should always be installed at hose couplings to allow for easy removal.
Term
PRVs
Definition
Nfpa14 recommendarions, most fire codes require them for outlets of systems where static pressure could exceed 175 psi. Most prvs act as check valves
Term
device vs. Valve
Definition
  • Valve: internal components assoc. With its pressure regulation that cannot be removed.
  • Device: when there are either external componenets such as limiting devices, or internal components such as an orifice plate. Seperate from actual valve and can be removed.
Term
4 categories of pressure-regulating and reducing valves
Definition
  1. Factory preset
  2. Field adjustable

Definition

Standpipe inline gauge

probably the most important of the water delivery appliances second only to the nozzle

Term

Definition
To establish a sustained water supply
Term
Proper weapon selection
Definition
Items such as bldg construction, type of occupancy, size of the bldg including the area and height. What type of auxiliary appliances exist within the bldg, whether the bldg has standpipes
Term

the colder the weather and the higher the bldg the greater the stack effect

Term
Stratification of smoke
Definition
As the smoke rises inside a tall high rise building, it cools down, loses its buoyancy, stops traveling upward, stratifies and begins to spread laterally
Term
Mushrooming of smoke at the upper levels of a fire building
Definition
Smoke can quickly bank down and build up. Dangerous smoke conditions on several upper floors
Term

spotting the pumper so that the FDC is on the opposite of the pumper from the pump panel

Term
Precontrol overhaul
Definition

Most important of the two overhauls

check all six directions

begiat with the fire apt. Then any exposure apts. if fire extended into public hallway, then other apts. must be checked for extension

next, the apt. on the floor above directly above the fire apt. Then the top floor
