Understanding Smoke Alarm Safety

Smoke detectors were an amazing invention and has since saved thousands of lives every year. Every home should have a smoke detector, actually new code requires one on every floor and outside every bedroom. This is done to save as many lives as possible during a home fire.
Smoke Detectors need to be changed out every 10 years and Sparky the Fire Dog has a cute little video to show you how to check the date on your alarms!

All smoke detectors consist of two basic parts: a sensor to sense the smoke and a very loud electronic horn to wake people up. Smoke detectors can run off of a 9-volt battery or 120-volt house current.
Three out of five home fire deaths in 2009-2013 were caused by fires in homes with no smoke alarms or no working smoke alarms.
Working smoke alarms cut the risk of dying in reported home fires in half.
In fires considered large enough to activate the smoke alarm, hardwired alarms operated 94% of the time, while battery powered alarms operated 80% of the time.
When smoke alarms fail to operate, it is usually because batteries are missing, disconnected, or dead.
An ionization smoke alarm is generally more responsive to flaming fires and a photoelectric smoke alarm is generally more responsive to smoldering fires. For the best protection, or where extra time is needed to awaken or assist others, both types of alarms, or combination ionization and photoelectric alarms are recommended.
