Myth Smoke Alarms Alone are Enough While Smoke Alarms are a
proven life-saving fire protection device, they serve as a
notification of smoke, and can do nothing to remove or reduce the
heat or smoke.
Slide 3
Smoke Alarm Trends in Fatal Fires Smoke Alarm Trends in Fatal
Fires Sources: NFPA; UFSA; Public/Private Fire Safety Council 40%
of fire deaths in homes each year occur in homes with working smoke
alarms. This is trending in the wrong direction!
Slide 4
Vulnerable Populations Source: NFPA Children Children under the
age of 5 are 1 times more likely to die in a home fire as the
general public Babies cannot self-evacuate Young children often
hide during fires or need assistance Children may sleep through a
sounding smoke alarm Children have reduced reaction times
Slide 5
Vulnerable Populations Source: NFPA Older Adults The elderly
are nearly 3 times more likely to die in a home fire as the general
public Older adults may suffer from reduced sensory abilities such
as smell, touch, vision, and hearing Inability to smell smoke
Inability to feel if something is hot Inability to see fires or
notice fire causes Inability to hear smoke alarms or fire sounds
Older adults may suffer from disabilities Older adults have reduced
reaction times
Slide 6
Myth If My Smoke Alarm has a false activation, the Sprinklers
will Activate Fire sprinklers and Smoke alarms have different
operating principles Smoke Alarms respond to particles in the air
Sprinklers rely on heat to activate Cigars, cigarettes, etc will
not activate sprinklers!
Slide 7
Myth If My Smoke Alarm has a false activation, the Sprinklers
will Activate Fire sprinklers and smoke alarms are not connected

Myth - New Homes are Safer Most residential fire deaths result
from fire caused directly or indirectly by people, and arent
related to the homes age While older homes (+40 years) are more
vulnerable to fire due to older wiring, there are new risks: Modern
fuels and lightweight construction. Smoking is the leading cause of
fire deaths Cooking is the leading cause of residential fires

Slide 13
Myth If fire deaths have declined over the years in the US, we
have less of a need to have active protection. Home fire deaths
have declined since 1977, but a 2500 per year average has been
occurring consistently since the late 1990s Source: NFPA Annual

Myth Home Fire Sprinklers Leak A residential sprinkler system
is not any more likely to leak than fixtures in a plumbing system

warranty their work!
Slide 15
Myth When One Head Activates, They All Activate This is a myth
that is sometimes perpetuated by Hollywood Sprinklers are each
independently heat- sensitive. They activate separately! Commonly,
only a single sprinkler will activate in a home fire.

Myth Home Fire Sprinkler Systems Require A Lot of Maintenance
The Maintenance Standard, NFPA 25, excludes One & Two Family
Dwellings 13D maintenance requirements are simple: Walk the
sprinklers periodically (no specific time requirement) to look for:
Obstructions to discharge (storage, etc) Painted or damaged heads

Myth Home Fire Sprinkler Systems Use A Lot of Water The
Scottsdale Report revealed that a typical sprinkler activation in a
home uses an average of 341 gallons of water, compared to an
average fire department suppression amount of 2,935 gallons.
Source: HFSC
Slide 20
Myth Home Fire Sprinkler Systems Use A Lot of Water -13D allows
for a design using the same water demand of the domestic system The
fire sprinkler demand and the domestic system demand do not need to
be added together; they can be concurrent Source: NFPA 13D

50% and 92% in a 2010 FM global Study Source: FM Global

Upgrades Water Meters 5/8 Rated for 20 gpm max. Recommend staying
within rating, but tests have shown meter will not fail with excess
flow 3/4 Rated at 35 gpm Should work for most systems Requirement

Myth Sprinkler Requirements Will Slow Down a Housing Market
Sources: NFPA; NAHB Impact on Housing Supply and Costs A 2009 study
found no evidence that the enactment of of sprinkler ordinances
caused any detrimental effects on housing supply and costs
Statistics on the website of the National Association of Home
Builders (NAHB) show single-family home building permits increased
on average by 28 percent in the United States between April 2012
and April 2013, but California experienced a 55 percent increase in
permits in the same period

Myth My Insurance Rates Will Increase If I Have Sprinklers
Nationally, on average, you not only dont get penalized, you get
rewarded. Most insurance companies offer a premium discount for
having a fire sprinkler system in the home. Sources: 2008 FPRF
