Sprinkler Systems in Industry
Residential Sprinkler Myths and Facts
Have you ever heard someone say “If one sprinkler head goes off, they all go off.” or “The sprinklers may go off accidentally.”? Read the facts behind these myths about residential sprinklers.
Schools, office buildings, factories, and other commercial buildings have benefited from fire protection sprinkler systems for over a century. To prevent investments in buildings and machinery, the textile mills in New England began using sprinkler systems over 100 years ago following a series of devastating fires which claimed many lives and destroyed entire businesses.
Sprinklers in Homes
But what about our homes? Although we protect our businesses from fire, what actions do we take to protect our families, our homes, and our possessions from fire? Millions of Americans have installed smoke alarms in their homes in the past few years, but a smoke alarm can only alert the occupants to a fire in the house … it cannot contain or extinguish a fire. Residential sprinkler systems can!
Fires in residences have taken a high toll of life and property. In 2005 there were:
- 396,000 residential fires
- 3,055 civilian fire deaths
- 13,825 civilian fire injuries
- $6.9 billion in property damage

Studies by the Federal Emergency Management Agency’s United States Fire Administration indicate that the installation of residential fire sprinkler systems could have saved thousands of lives; prevented a large portion of those injuries; and eliminated hundreds of millions of dollars in property losses.
What Are Home Fire Sprinkler Systems?
Using quick response sprinklers and approved piping, homes can be built or even retrofitted to include low-cost automatic sprinkler systems connected to the domestic water supply.
Sprinkler systems offer advantages to the homebuilder:
- A low-cost reliable safety option that would attract many buyers.
- Trade-offs between sprinklers and code requirements that can result in lower construction costs, more units per area of land, etc.
For homeowners, the advantages include assurance of a safer environment for their families, protection of their investment and irreplaceable family possessions, and lower insurance rates 5 to 15 percent.
Advantages of Newly Designed Home Sprinkler Systems
Residential sprinklers, listed by Underwriters Labs, are now available. They are designed to respond to a fire much faster than currently available standard commercial and industrial sprinkler systems. The new home sprinklers react automatically to fires more quickly because of their improved sensitivity.
At the present time, cost of a home sprinkler system is targeted at approximately $1.00 to $1.50 per square foot in new construction. It is hoped that the cost will decrease as the use of home fire protection grows. It is also possible to retrofit existing homes with sprinkler systems.
For residential systems, the sprinklers will be smaller than traditional, commercial, and industrial sprinklers, and can be aesthetically coordinated with any room decor.
Minimal Installation Work
When homes are under construction or being remodeled, a home sprinkler system will require minimal extra piping and labor.
Low Water Requirement
These systems will require less water than the systems installed in industrial or commercial establishments and can be connected to the domestic water supply.
In addition to metallic pipe, the use of plastic pipe has brought down the cost of installation in new construction and the retrofit of existing structures.
Some notable successful applications of residential sprinklers and approved piping include:
- Addison, TX
- Prince George’s County, MD
- Scottsdale, AZ
A Growing Number of Communities Promote Home Fire Sprinklers
The fire loss in this country in residential occupancies is alarming. Manual firefighting methods are not the answer. The way to attack the problem is to limit the fire growth where it occurs in dwellings. We have the technology to do that.
Residential Automatic Sprinkler Systems. Ordinance No. 745; Adopted May 28, 1969; by the San Clemente, California City Council
Proposition 13 was a major factor in promoting the ordinance. There is also a shift within the fire service toward more fire prevention and less suppression emphasis. San Clemente and Corte Madera, California were some of the first communities in the United States to enact a home sprinkler ordinance. Other communities that have initiated or plan to initiate residential sprinkler ordinances include:
- Livermore, California
- Montgomery County, MD
- Long Grove, Illinois
- Chapel Hill, North Carolina
- Germantown, Tennessee
- Scottsdale, Arizona
- Altamonte Springs, Florida
Test Your Home Sprinkler System’s I.Q.
Here are five statements about home sprinkler systems. Are they true or false?
- When one sprinkler goes off, all the sprinklers activate.
False! Only the sprinkler over the fire will activate. The sprinkler heads react to temperatures in each room individually. Thus, fire in a bedroom will activate only the sprinkler in that room.
- A sprinkler could accidentally go off, causing severe water damage to a home.
False! Records, which have been compiled for well over 50 years, prove the likelihood of this occurring is very remote. Furthermore, home sprinklers will be specifically designed and will be rigorously tested to minimize such accidents.
- Water damage from a sprinkler system will be more extensive than fire damage.
False! The sprinkler system will severely limit a fire’s growth. Therefore, damage from a home sprinkler system will be much less severe than the smoke and fire damage if the fire had gone on unabated or even the water damage caused by water from firefighting hose lines.
- Home sprinkler systems are expensive.
False! Current estimates suggest that when a home is under construction, a home sprinkler system could cost less than 1% of the total building price.
- Residential sprinkles are ugly.
False! The traditional, commercial-type sprinklers as well as sprinklers for home use are now being designed to fit in with most any decor.
Sprinklers Are a Good Investment for Homebuilder’s
Through the use of construction trade-offs, homebuilders and developers can achieve reduced construction costs if residential sprinkler systems are installed. Home sprinkler systems offer both safety and financial advantages to homebuyers, a rare combination.
Sprinklers Are a Good Investment for the Homebuyer
- A fire occurs in a residential structure every 79 seconds, according to the U.S. Fire Administration. To the homebuilder, this fact means that a large share of potential customers now have knowledge of the terror and destruction caused by fire.
- Families with children, senior citizens, and handicapped members have special fire protection needs. Home sprinkler systems provide added protection for these people.
- In case of a home fire, firefighters will have less risk of injury or life loss since they will be fighting a fire of less intensity.
- Allocation of community resources can be improved with the adoption of home sprinkler technology.
- Communities will be able to make better utilization of available land and thereby increase their tax base.
Insurance from homeowner underwriters will vary depending on type of coverage. The discounts now range between 5-15%, with a projected increase in available discounts.
The Move Toward Home Sprinkler Systems
The U.S. Fire Administration’s research in home fire sprinkler systems successfully focused on systems that would be low cost, fast acting and reliable. As a result, residential fire sprinklers have gained increased acceptance.
In November 1980, the National Fire Protection Association adopted the NFPA 13D Residential Sprinkler installation standard. The standard is based on technical data from the comprehensive full-scale fire tests, which were sponsored by the U.S. Fire Administration.
Residential Sprinkler Program
Dedicated to reducing this Nation’s staggering loss of life and property caused by fire, the Federal Emergency Management Agency’s U.S. Fire Administration has joined with private industry and the fire service to advance the development of residential sprinklers. Since 1976, the Fire Administration has promoted research studies, development and testing, and demonstrations of residential sprinkler systems.
