Committee Statement

CommitteeStatement:

Many times a convenience stair will be located in a building that requires standpipes. Many AHJ'sinsist that if the stair is provided, it must be required and therefore a standpipe must be provided.Many times this stair is in a lobby or open area and providing hose outlets is difficult to accomplish.

Committee Statement

CommitteeStatement:

Currently the standard requires hose connections in required exit stairs. A typical arrangementfound on many garden style apartments is to have (2) egress stairs spaced rather close whichprovides occupants two means of egress. These stairwells are generally open. Many AHJ's require astandpipe for each stairwell. Since the stairs are open, allowing a single standpipe/hose connectionin the corridor should not pose any greater risk. The attached PDF is for reference only to illustratethe scenario and is not intended to be used for a figure.

We have seen more than a few pressure gauge installations in the field where the gauge wasinstalled in a location where it was impossible to remove the gauge for inspection or replacement ofthe gauge. The existing text does not have anything about locating the gauge assembly as to permitremoval of the gauge. if the gauge is inaccessible, this makes it more difficult to perform requiredtesting and maintenance, and the building owner has additional costs of repairs to make the gaugesaccessible.

NFPA-13 8.1.2: "System valves and gauges shall be accessible for operation, inspection, tests, andmaintenance."

NFPA-13 8.17.3.4: "Gauges shall be installed to permit removal and shall be located where they willnot be subject to freezing."

A.6.3.1.5

Manual wet standpipe systems can be installed by themselves or as part of a combination system. Usually with a combination system, there will be the required valves as part of the sprinkler system requirements from either NFPA 13, Standard for the Installation of Sprinkler Systems or NFPA 13R, Standard for the Installation of Sprinkler Systems in Low Rise Residential Occupancies. In systems with only a manual wet standpipe, connection to any readily available water source is acceptable. The control and check valves only need to be approved. A common scenario is to connect the system to the potable water system which may require some form of cross connection control which may satisfy the valving requirement. There is no minimum size requirement for this connection.

There should be no need to require the control and check to be the same size as the connection. Ifthe hydraulic calculations for the sprinkler system prove it works, then the size shouldn't beregulated. An example might be where a single saddle is drilled into the standpipe and 2 1/2" ispiped out and teed to a hose connection. Then the piping is reduced to 1 1/2" for the sprinklersystem because it is all that is needed. As written, the sprinkler control and check would need to be2 1/2" which makes no sense.

The term systems is not clear. As an example a single zone standpipe with a water storage tankand fire could be located above the pumping capacity of the fire department (example floors100-130) and because the "system" is a single zone, a back up supply would not be required. Usingthe term "building" would include all standpipe zones in the building even if there are multiplestandpipe systems.

A.7.8

Where determining the pressure at the outlet of the remote hose connection, the pressure loss in the hosevalve should be considered.

It is very important that fire departments choose an appropriate nozzle type for their standpipe fire-fightingoperations. Constant pressure- (automatic-) type spray nozzles ( ( seeNFPA 1964 ) NFPA 1964 ,Standard for Spray Nozzles ) should not be used for standpipe operations because many of these typesrequire a minimum of 100 psi (6.9 bar) of pressure at the nozzle inlet to produce a reasonably effective firestream. In standpipe operations, hose friction loss could prevent the delivery of 100 psi (6.9 bar) or 75 psi(5.2 bar) to the nozzle.

In high-rise standpipe systems with pressure-reducing hose valves, the fire department has little or nocontrol over hose valve outlet pressure.

Many fire departments use combination (fog and straight stream) nozzles requiring 100 psi (6.9 bar)residual pressure at the nozzle inlet with 11⁄2 in., 13⁄4 in., or 2 in. (40 mm, 44 mm, or 50 mm) hose inlengths of up to 150 ft (45.7 m). Some use 21⁄2 in. (65 mm) hose with a smooth bore nozzle or acombination nozzle.

Some departments use 50 ft (15.2 m) of 21⁄2 in. (65 mm) hose to a gated wye, supplying two 100 ft (30.5m) lengths of 11⁄2–2 in. (40–50 mm) hose with combination nozzles, requiring 120–149 psi (8.3–0.3 bar) atthe valve outlet. (See Table A.7.8.)
