Even though regulations didn't require a fire sprinkler system, the building was equipped with one from the beginning.

The sprinkler system cost 4 million dollars.

See rainwater, sprinkler system, drip irrigation, tap water, greywater, hand pump and watering can.

When the sprinkler arrives back at the reel the system shuts off.

This type of system is known to most people as a " waterreel " traveling irrigation sprinkler and they are used extensively for dust suppression, irrigation, and land application of waste water.

A fire sprinkler system is often provided to control a full scale fire if it develops.

Clean agent fire suppression gaseous systems are sometimes installed to suppress a fire earlier than the fire sprinkler system.

The argument could be made that the installation of a sprinkler system could pay for itself quickly, instead of having to pay a fire fee each year.

She locks the doors and turns on the sprinkler system.

The Borland main office was near the epicenter of the Loma Prieta earthquake and the building was severely damaged when the sprinkler system was triggered.

New and old building design, building systems like the building standpipe system, HVAC systems ( Heating, Ventilation and Air conditioning ), fire sprinkler system and other things like stairwell and elevator evacuations pose significant problems.

There are internal and external stairways with a standpipe and sprinkler system throughout, only fed with water by an engine during training.

** The installation of a pressurized sprinkler system.

A National Institute of Standards and Technology ( NIST ) investigation of the fire, using computer simulations with FDS and a mock-up of the stage area and dance floor, concluded that a fire sprinkler system would have contained the fire long enough to give everyone time to get out safely.

However, because of the building's age ( built in 1946 ) and size ( 4, 484 square feet ( 404 m² )), many believed the Station to be exempt from sprinkler system requirements.

On the night in question, the Station was legally required to have a sprinkler system but did not ; outcry over the event has sparked calls for a national Fire Sprinkler Incentive Act but those efforts have so far stalled.

While the type of foam used and the lack of a sprinkler system were important factors in the fire, the Great White fire could likely have been prevented had those involved paid attention to standard safety practices around the use of pyrotechnics.

A fire sprinkler system is an active fire protection measure, consisting of a water supply system, providing adequate pressure and flowrate to a water distribution piping system, onto which fire sprinklers are connected.

The world ’ s first recognizable sprinkler system was installed in the Theatre Royal, Drury Lane in the United Kingdom in 1812 by its architect.

The first automatic sprinkler system was patented by Philip W. Pratt of Abington, MA, in 1872.

Once there is no more water pressure in the lateral line, the sprinkler head will retract back into the ground.

A glass bulb type sprinkler head will spray water into the room if sufficient heat reaches the bulb and causes it to shatter.

For example, the presence of a sprinkler system will usually permit doubling of compartment sizes and increases in travel distances ( to fire exits ) as well as allowing a reduction in the fire rating of internal compartment walls.

A sprinkler activation will do less damage than a fire department hose stream, which provide approximately 900 liters / min ( 250 US gallons / min ).

However, a typical Early Suppression Fast Response ( ESFR ) sprinkler at a pressure of will discharge approximately.

In addition, a sprinkler will usually activate between one and four minutes, whereas the fire department typically takes at least five minutes to arrive at the fire site after receiving an alarm, and an additional ten minutes to set up equipment and apply hose streams to the fire.

Prior to fire detection, if the sprinkler operates, or the piping system develops a leak, loss of air pressure in the piping will activate a trouble alarm.

In this case, each sprinkler head is usually marked, so that landscaping crews will not cover or bury them with soil or sod, or damage them with tractors or other construction equipment while digging holes for trees, shrubs, or other large plants or fenceposts.

In March 2012, the St-Mathieu exit of the station is undergoing renovation work that will include new flooring, ceilings, walls, lighting, as well as sprinkler and electrical systems.

Under standard testing procedures ( 135 ° C air at a velocity of 2. 5 m / s ), a 68 ° C sprinkler bulb will break within 7 to 33 seconds, depending on the RTI.

Automatic fire sprinklers operate at a predetermined temperature, utilizing a fusible element, a portion of which melts, or a frangible glass bulb containing liquid which breaks, allowing the plug in the orifice to be pushed out of the orifice by the water pressure in the fire sprinkler piping, resulting in water flow from the orifice.

Because each sprinkler activates independently when the predetermined heat level is reached, the number of sprinklers that operate is limited to only those near the fire, thereby maximizing the available water pressure over the point of fire origin.

Rainguns are similar to impact sprinkler, except that they generally operate at very high pressures of 40 to 130 lbf / in² ( 275 to 900 kPa ) and flows of 50 to 1200 US gal / min ( 3 to 76 L / s ), usually with nozzle diameters in the range of 0. 5 to 1. 9 inches ( 10 to 50 mm ).

* Lower design flexibility-Regulatory requirements limit the maximum permitted size ( i. e., 750 gallons ) of individual dry-pipe systems, unless additional components and design efforts are provided to limit the time from sprinkler activation to water discharge to under one minute.

Contrary to motion picture representation, the entire sprinkler system does not activate, unless the system is a special deluge type.

* Increased fire response time-Because the piping is empty at the time the sprinkler operates, there is an inherent time delay in delivering water to the sprinklers which have operated while the water travels from the riser to the sprinkler, partially filling the piping in the process.

In addition to rain pouring in from the holes in the roof, there was also water damage from the sprinkler system and broken water pipes.

It is named after John C Erfurt and Walter E. Runkel ( which are now both in suspension there ), and has a sprinkler system for additional security.

This reflected an ongoing debate at the time among archivists and librarians about the relative merits of sprinkler systems: Some felt that there was a greater chance for water damage from the activation of one or more sprinkler heads, whether in a fire or accidentally, than the chance of fire damage without sprinklers to suppress it, while others were of the opposite opinion.

But since fibreglass resin is highly flammable, and there was no sprinkler system, the fire spread to the 6 dhows and the fibreglass resin barrels in the yard.

It is possible to define the intensity of the water coming from a garden sprinkler, but intensity is used most frequently with waves ( i. e. sound or light ).

In sprinkler or overhead irrigation, water is piped to one or more central locations within the field and distributed by overhead high-pressure sprinklers or guns.

As the tubing is wound on the drum powered by the irrigation water or a small gas engine, the sprinkler is pulled across the field.

Other travelers use a flat rubber hose that is dragged along behind while the sprinkler platform is pulled by a cable.

Center pivot irrigation is a form of sprinkler irrigation consisting of several segments of pipe ( usually galvanized steel or aluminum ) joined together and supported by trusses, mounted on wheeled towers with sprinklers positioned along its length.

Center pivot irrigation is a form of overhead sprinkler irrigation consisting of several segments of pipe ( usually galvanized steel or aluminum ) joined together and supported by trusses, mounted on wheeled towers with sprinklers positioned along its length.

An example is the fire sprinkler lobby, which favours active fire protection, whereas members of the passive fire protection trades, for instance the International Firestop Council would argue the merits of its members ' work.

Henry S. Parmalee of New Haven, Connecticut is considered the inventor of the first automatic sprinkler head.

Consequently, the total building cost is often less by installing a sprinkler system and savings money in the other aspects of the project, as compared to building a non-sprinklered structure.

In the UK, since the 1990s sprinklers have gained recognition within the Building Regulations ( England and Wales ) and Scottish Building Standards and under certain circumstances, the presence of sprinkler systems is deemed to provide a form of alternative compliance to some parts of the codes.

Each closed-head sprinkler is held closed by either a heat-sensitive glass bulb or a two-part metal link held together with fusible alloy.

In a standard wet-pipe sprinkler system, each sprinkler activates independently when the predetermined heat level is reached.

When one or more of the automatic sprinklers is exposed, for a sufficient time, to a temperature at or above the temperature rating, it opens, allowing the air in the piping to vent from that sprinkler.

In regions using NFPA 13 regulations, the time it takes water to reach the hydraulically remote sprinkler from the time that sprinkler is activated is limited to a maximum of 60 seconds.
