Medford Residential Fire Statistics
Local In the 25-year period between 1989 and 2013, Medford experienced 22 fire related deaths that occurred inside of structures located on residential properties. Most fire deaths are caused from smoke inhalation and occur between midnight and 8:00am Each fire tragedy effects family, friends, firefighters, and the community Source: NFPA

Vulnerable Populations
Children Children under the age of 5 are 1 ½ times more likely to die in a home fire as the general public Young children often hide during fires or need assistance Children may sleep through a sounding smoke alarm Children have reduced reaction times Source: NFPA
9
Vulnerable Populations
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 Source: NFPA

Why Do We Still Lose People in Home Fires?
Safe Window of Escape Time Studies have shown that the average safe window of escape time has been reduced from 17 minutes in the 1970’s to as little as three minutes currently. This change is attributed to the widespread use of hydrocarbons (petroleum products) in modern furniture, such as plastics and polyurethane foams. These newer fuels cause more rapid fire growth. Smoke and products of combustion from these fires become deadly in a matter of just a few minutes. People are dying because they simply do not wake up or cannot get out in time. Source: NIST

Why Do We Still Lose People in Home Fires?
Some Would Say Smoke Alarms are Enough… They may not provide an early enough warning for everybody to escape todays fast moving home fires Smoke alarms were present and operated in 40% of home fire deaths There are maintenance issues 37% of fire deaths were in homes with missing smoke alarms 23% of fire deaths were in homes where smoke alarms were inoperable Source: NFPA’s Smoke Alarms in U.S. Home Fires, March 2014

The polyurethane foams and plastics in modern day furnishings are basically made out of hydrocarbons similar to gasoline. It has been said that polyurethane foam is just solidified gasoline. This is why we are experiencing such rapid and intense fires in homes. Source: NFPA 921; Kirk’s Fire Investigation

The Facts - Flashover Residents Do Not Survive Flashover
Flashover is caused when a fire produces enough radiant heat in a room to ignite all of the combustible items within the room simultaneously Flashover can occur in as little as 3-4 minutes Conditions can become fatal in about ½ the time to flashover Most victims in post-flashover fires are found remote from the room of origin Flashover is the most dangerous phase of a room fire, where the fire is turbulent and is producing massive amounts of smoke and toxic gases. It is a phase of the fire where there is sufficient radiated heat to simultaneously ignite all of the combustibles in a room. It can occur in as little as 3-4 minutes. If someone is still in the structure when flashover occurs, even remotely from where the flashover takes place, they will most likely perish. Source: NIST

Typical Fire Scenario w/o Fire Sprinklers
Ceiling temp reaches 1,400 degrees. Flashover occurs engulfing all contents of the fire room and extending fire throughout home A small fire starts in your home Smoke reaches the smoke detector Ceiling temp. reaches 165 degrees. Smoke begins to layer down Ceiling temp. reaches 1,000 degrees, visibility is reduced to zero Severe fire damage results. Extensive water is used for firefighting suppression efforts. Average time of displacement...6 months to a year. Time Line (minutes) You are awakened by the smoke detector You investigate and find a fire You awaken other family members and go to a neighbor to call 911 You give the 911 operator the information and she notifies the fire dept. The fire dept. responds A structure fire in an unprotected residence continues to grow. The atmosphere can become toxic within 3-5 minutes after ignition. The fire department rarely will be able to put water on the fire within 10 minutes after ignition. If flashover occurs, it is highly unlikely that anybody still in the structure will be able to survive. The fire dept. arrives, assesses the situation & applies 250 gpm per hose to fire areas. Windows are broken and holes are cut in the roof to vent fire gases and smoke. Typical Fire Scenario w/o Fire Sprinklers Source: Oregon Home Fire Sprinkler Coalition

What If Homes were Sprinklered?
NFPA 13D was first adopted in 1975. The purpose of this standard shall be to provide a sprinkler system that aids in the detection and control of residential fires and thus provides improved protection against injury and life loss. The standard is designed to prevent flashover (total involvement) in the room of fire origin, where sprinklered, improving the chance for occupants to escape or be evacuated. By percentage, most civilian fire deaths are attributed to fires that begin in the living room/family room/den (24%), a bedroom (24%), or the kitchen (14%). NFPA 13D By percentage, most civilian fire deaths are caused by smoking materials (23%), radiated heat from operating equipment (13%), or arcing (13%). NFPA 13D By percentage, the item first ignited for most civilian fire deaths are upholstered furniture (19%) or mattress or bedding (13%). NFPA 13D

Typical Fire Scenario with Sprinklers
A small fire starts in your home Smoke reaches the smoke detector Ceiling temp. reaches 165 degrees. The sprinkler head over the fire activates Fire is controlled or completely extinguished. Sprinkler head continues to spray water at 15 gpm. Average time of displacement from home days. Time Line (minutes) You are awakened by the smoke detector You investigate and find a fire You awaken other family members and go to a neighbor to call 911 You give the 911 operator the information and she notifies the fire dept. The fire dept. responds In a residence protected by fire sprinklers, the fire is controlled before it gets to it’s most destructive phase. A minimal amount of water controls the fire long before the fire department arrives. The fire dept. arrives, assesses the situation and limits water damage by shutting down the water supply to the sprinkler system. The fire department then assists with initial clean-up operations.

What If Homes were Sprinklered?
Model Building Codes: National Standard of Care National Fire Protection Association (NFPA) Required fire sprinklers in all new homes in 2005 International Code Council (ICC) Required fire sprinklers in all new homes in 2009 State Adoptions of Model Codes CA required fire sprinklers in all new homes 2011 First ordinance in San Clemente 1970’s 153 ordinances when starting to talk about statewide requirement 4 years later passed a statewide requirement MD required fire sprinklers in all new homes in 2011 Where Are We at in Oregon? Statewide multi-family requirement (2010) for new construction (3+ units) No statewide requirement to protect one and two family homes

Proven Case Studies Residential Fire Sprinklers
Scottsdale, AZ (15 Year Study)1 Ordinance enacted in 1986 Over 50% of houses sprinklered No fire deaths in sprinklered homes 13 people died in non-fire sprinklered homes Over $20 million in property loss prevented Average fire loss was: $2,166 in fire sprinklered residences $45,019 in non-fire sprinklered residences The Scottsdale fire sprinkler ordinance has been credited with saving 13 lives. In the Scottsdale Report, the average fire loss in a residences protected with fire sprinklers was a fraction (< 5%) of the potential fire loss had the structures not been protected.

Proven Case Studies Residential Fire Sprinklers
Prince George’s County, MD (15 Year Study) 1 Ordinance Enacted in 1992 Reported Home Fires: 13,494 Reported Home Fire Sprinkler Activations: 245 Homes Protected with Fire Sprinklers 446 people present in homes Fire Deaths: 0 Fire Injuries: 6 (all minor in nature) Total Fire Loss: $ 1,352,820.00 Potential Fire loss: $ 42,578,420.00 Unprotected Homes: Fire Deaths: 101 Fire Injuries: 328 The Prince George County fire sprinkler ordinance has been credited with saving 154 lives. In addition, the total fire loss in residences protected with fire sprinklers was just 1% of the potential fire loss had the residences not been protected. Source: Home Fire Sprinkler Coalition

Case Study Conclusions
Fire Sprinkler Experience Studies in jurisdictions that had long-standing fire sprinkler ordinances have proven that residential fire sprinkler systems are effective in saving lives, reducing injuries, and reducing property damage The National Institute of Technology (NIST) compared sprinklered and non-sprinklered homes over a period of time and came to the following conclusions: Houses equipped with smoke alarms and a fire sprinkler system experienced 100 % fewer civilian fatalities, 57 % fewer civilian injuries, and 32 % less direct property losses and indirect costs resulting from fire than houses equipped only with smoke alarms.

The Solution + => Survival
Your Chances of Surviving a Fire Increase Significantly with: A fire sprinkler system and Smoke alarms Resident Benefits in Addition to Life Safety Value Much less property damage Valued possessions will most likely be spared Will not have to relocate for an extended period of time while residence is rebuilt Your chances of surviving a residential structure significantly increase when the structure is protected with both fire sprinklers and smoke alarms. The added benefit is the protection and preservation of your property. Source: NFPA; Firesafehome.org

Community Benefits Available Personnel & Economics
Serious Residential Fire without Fire Sprinklers Residential Fire with Fire Sprinklers Average Staffing for Extended Duration 15.5 personnel 60.1 staff-hours Mutual aid required for other normal responses + Overtime crews + Overtime investigation A structure fire in a residence takes a lot of water and manpower to extinguish and overhaul. When all is said and done, there is usually considerable damage to both the structure and the contents. Frequently, the occupants are barely able to escape and they lose everything they own. Average Staffing for Short Term 3 personnel 6 staff-hours No overtime crews Units immediately available for another response Possible short duration overtime Investigation

Community Benefits Environmental Considerations
Environmental Impact of Sprinklered vs. Non-Sprinklered Homes Greenhouse gas emissions were cut by 97.8% Water usage was reduced between 50% and 92% Fewer persistent pollutants, such as heavy metals, were found in sprinkler wastewater versus fire hose water The high PH level and pollutant load of non-sprinkler wastewater are an environmental concern Source: Home Fire Sprinkler Coalition and FM Global
31
Public Perception 2014 National Harris Poll
74% of U.S. homeowners said they would be more likely to buy a home with fire sprinklers than one without Seven in 10 said a sprinklered house has more value Nearly 8 in 10 (78%) said fire sprinklers provide the ultimate protection for residents Source: Home Fire Sprinkler Coalition

Sprinkler Ordinances: Is There an Impact on Housing?
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. 1. 2.
