While modern sprinkler systems have been a standard for decades, with more sprinkler system advances coming on line every year, it’s fascinating that sprinkler systems actually got their start in the 15th century.
It should be no surprise that the brilliant Leonardo da Vinci designed a sprinkler system for a wealthy patron that included conveyor belts and a super-oven for entertaining large groups of people. Alas, things did not turn out as expected. During a huge banquet, a fire started and the sprinkler system worked so well that it washed away all the food and part of the kitchen!
Several hundred years later, Ambrose Godfrey developed the first automated sprinkler system in 1723 – with gunpowder used to release a tank of fluid designed to extinguish fires.
In 1812, architect William Congreve developed and installed the first sprinkler system in a commercial building. This first commercial sprinkler system made its debut in the United Kingdom at the Theatre Royal, Drury Lane.
In 1881, Frederick Grinnell enhanced a sprinkler system design from Henry Parmalee, and patented it. Grinnell continued his R&D work, and invented the glass disk sprinkler in 1890 that is still used today.
Fast forward roughly 100 years, and a series of deadly fires drove the development of new mandates for sprinkler systems in buildings including:
- 1977, May 28 – Beverly Hills Supper Club Fire, Kentucky (165 deaths)
- 1980, Nov. 21 – MGM Grand Hotel (85 deaths)
- 1980, Dec. 4 – Stouffer’s Inn, NY Fire (26 deaths)
- 1981, Feb. 10 – Las Vegas Hilton Fire (8 deaths, 200+ injuries)
“After the MGM fire, Bill Marriott started retrofitting his hotels with sprinkler systems,” recalled Asurio President Top Myers. “Soon after that, the Hilton CEO followed suit.”
This started a groundswell for installing sprinkler systems as well as making significant upgrades & changes to fire codes. “Once those fires occurred, the next question was: ‘What happeneds if the sprinkler system doesn’t work?’ That’s when a task force at NFPA started looking at how to handle this, which resulted in the birth of NFPA 25 inspection standards,” said Mr. Myers. (Editor’s note: Asurio President Top Myers has served on the NFPA 25 committee since the day it was founded. He also participates in the development of new standards and code enhancements for NFPA 72 & NFPA 915.)
Insights Into Pending Sprinkler System Advances
History is important because it provides context on the development of sprinkler systems & the evolution of fire code standards. Fire protection contractors & facility managers also will find it helpful to gain an insider perspective on technical innovations in sprinkler systems & related code changes.
With that in mind, here are Top Myers’ insights on four pending sprinkler system advances that will come to fruition in coming years.
Sprinkler System Advances – Take 1: NFPA 915, i.e. Remote Testing
The computer is getting involved in fire-life safety in a way that it’s never been done before. This refers to an increasing use of technology such as video, drones & electronics that will monitor & control fire sprinkler systems. (Editor’s Note: Asurio President Top Myers has just been appointed to the NFPA 915 code standards committee.)
Sprinkler System Advances – Take 2: Water Mist Sprinkler Systems
When you sit in an outdoor patio in a hot climate, you probably enjoy a fine mist that helps keep you cool. This concept is being applied to new water sprinkler systems. Water mist sprinkler systems are used when the fire suppression goal is to create a heat-absorbent vapor. Water mist sprinkler systems help lower the heat of the fire because the mist turns to steam more quickly and cools the room. When water mist sprinkler systems hit the market, they will be most used in two scenarios: 1) When you want to minimize water damage, and 2) When the supply of available water is limited.
Sprinkler System Advances – Take 3: Smart Water Flow Switches
A key development in sprinkler systems will be the development & introduction of smart water flow switches. These new water flow switches will be able to self test & monitor themselves 24/7. Smart water flow switches will have a big impact on the industry because these switches ultimately will be applied & incorporated into a wide variety of fire safety equipment.
Sprinkler System Advances – Take 4: Specialty Sprinkler Heads
One sprinkler head design does not fit all applications. As a result, fire contractors can expect to see more and more specialty sprinkler heads hitting the market that are designed for use in very specific circumstances. For example, some sprinklers heads are being especially designed to work in attics. Others will be designed to spray water on three-dimensional items located within buildings. Still other specialty sprinkler heads will be designed for low water flow, either to minimize water damage or to conserve water in areas or facilities where water is at a premium.
The common denominator for most of the sprinkler system advances coming on line have to do with computer automation, according to Mr. Myers. “We are going to see a tsunami of new technology with smart, self-monitoring sprinkler systems and components as well as alarm systems and fire suppression equipment,” he noted. “As these new developments in fire-life safety come on line, it will require an inspection system that can incorporate the new equipment into inspections – so that fire-life safety contractors & facility managers can properly inspect and maintain them.”
