How many of you know what TYPE of smoke alarm you have?Does it Matter?
Based on industry information, what has the fire service been promoting for 30 years?
In spite of their differences, either one of the two types of smoke alarms is acceptable for home use.
Find the least expensive smoke alarm that is UL Listed.
Smoke Alarm History1970 - 1st battery smoke alarm (Apx. $30)1977 - National Institute of Standards & Technology (NIST) conducted smoke alarm testing1980s - 75% of homes had smoke alarms2004 - 96% of homes had smoke alarms2008 96% of homes had smoke alarms, 20% of homes do not have a working smoke alarm.
IONIZATION: Contains a small amount of radioactivity that conducts electricity. Ionization alarms are more sensitive to the tiny particles of combustion that cant be seen or smelled, those emitted by FLAMING FIRES.
Ionization alarms are more PRONE TO FALSE ALARMS from cooking and steam from bathrooms.
PHOTOELECTRIC: Contains a beam of light and a photocell within the chamber. Photoelectric alarms are more sensitive to the large particles of combustion emitted by SMOLDERING FIRES.
The Difference Does Matter.Here Is What We Have Learned
Andrea Dennis, Kyle Raulin,Al Schlessman, Erin DeMarco,and Christine Wilson
These five students died atOhio State University onApril 13, 2003 (Palm Sunday)
Julie Turnbull, Kate Welling & Steve Smith died in this house on April 10th, 2005 (Palm Sunday) at Miami University
Some of the Many Studies International Assn. of Fire Chiefs (IAFC) study-1980
Texas A & M-2 1/2 year study: 1990s
National Institute of Standards & Technology (NIST) sponsored private industry study-2001
The ResultsHave been consistent
Ionization alarms sounded tens of seconds faster than photoelectric alarms in flaming fires in many of the tests.Photoelectric alarms sounded tens of MINUTES faster in smoldering fires in many of the tests.Ionization smoke alarms failed to sound at all in some smoldering fires tests.
The ResultsIonization smoke alarms are more prone to nuisance false alarms from normal cooking and steam from the bathroom/shower.These false alarms cause residents to remove the batteries. The batteries do not get replaced.
What if a resident has only ionization smoke alarms?
Educate them on the sensor differences.Recommend they replace their ionization smoke alarms with photoelectric or add photoelectric smoke alarms in addition to their ionization alarms per our guidelines.Remind them to maintain all of their existing smoke alarms until they replace them.
How do you tell what sensor you have?
National statistics:90% of homes in the US are equipped with Ionization smoke alarms only.20% of homes have non-working smoke alarms.53% of these non-working alarms were due to missing/removed batteries; the leading reason being nuisance alarms.Non-working smoke alarms were found in 23% of home fire deaths.Investigations of fires in (Your City Here), at the minimum, support these national statistics.
By the wayWhat types of alarms are being used to protect our most vulnerable citizens?
Photoelectric smoke detectors are now the only type being utilized in all commercial buildings including hospitals, nursing homes, schools, day cares & apartments!

Your City HereThe majority of home fires occurring within Your City are of the slow burning smoldering type creating heavy smoke.In the past XX years all but one fire fatality occurring in Your City were caused by smoke inhalation.Fire investigations conducted by fire department personnel have found operational smoke alarms that failed to operate in smoke conditions.
Fire Department RecommendationBased on this information, the Fire Department is already recommending that Photoelectric smoke alarms be placed in all the recommended areas throughout the home.Amend the city ordinances that require smoke alarms to require photoelectric smoke alarms as the primary alarm.
The passage of this legislation is important for promoting and enhancing the life safety of the residents of Your City, furthering our continued commitment to exemplary service and safety for our citizens.
