Smoke Alarms Save Lives.
65% of home fire deaths happen in homes with no smoke alarms that work or no smoke alarms at all. When there is a fire, smoke spreads fast and you need smoke alarms to give you time to get out.
Smoke alarms that are properly installed and maintained play a vital role in reducing fire deaths and injuries. Having a working smoke alarm cuts the chances of dying in a reported fire in half.
Smoke alarms are the single most important item to help you survive a fire. While fire doesn’t have to happen, when it does, early warning is imperative for escape. The smoke alarm laws in the state have become more complicated in recent years. Here are the facts to help sort it out and make your life safer.
In January of 1998, state law changed for smoke alarms. Where we once asked citizens to change their smoke alarm batteries each time they changed their clock, the advent of the 10-year lithium battery has changed all that.
ANY smoke alarm that has reached the age of 10 years has lost much of its reliability and should be replaced. The replacement must be a state legal smoke alarm in one of three configurations:
- Ionization Type that contains a long life lithium battery and a hush feature
- Photoelectric Type that contains a conventional 9-volt battery (no hush feature required)
- Either Type of smoke alarm can be hard-wired into the electrical system so no battery is needed (a conventional backup battery alone may be included and Ionization still need the hush feature)
- A combination Ionization/Photoelectric smoke alarm may also be available, combining the best qualities of each alarm.
Never change the battery in a new technology smoke alarm. The battery will be good but the alarm unit itself simply does not work reliably for longer than the 10-year lifespan (dust build up in the sensing chamber, reductions in the effectiveness of radioactive elements in ionization types, and failure of electronic components). Smoke Alarms using lithium batteries are not under warranty when the battery is replaced.
Ionization smoke alarms also have a hush feature. This is a button that silences the alarm when nuisance smoke or shower steam accidentally set it off. By pushing the button, it will silence the device for up to 15 minutes before it resets itself. Taking the battery out to silence the alarm is no longer needed!
None of these features reduces the need to test every smoke alarm every month. There is no guaranteed lifespan for a lithium battery so you may only know it is dead when the test does not sound the alarm. Also, new alarms have the date recorded on the back so their age can be tracked.
- Install smoke alarms in every bedroom, outside each separate sleeping area and on every level of the home, including the basement. Interconnect all smoke alarms throughout the home. When one sounds, they all sound.
- Carbon monoxide alarms are not a substitute for smoke alarms.
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, both types of alarms or a combination alarm (photoelectric and ionization) should be installed in homes.
- Test alarms at least monthly by pushing the test button.
- Place smoke alarms on ceilings. Smoke rises: the higher up the alarm is, the sooner it will warn you of smoke. Avoid the space within 12 inches of a wall (if on the ceiling). If wall mounted, the top must be at least 4 inches below the ceiling and the bottom not more than 12 inches below the ceiling.
- Replace batteries in all smoke alarms at least once a year. If an alarm “chirps”, warning the battery is low, replace the battery right away.
- Replace all smoke alarms, including alarms that use 10-year batteries and hard-wired alarms, when they are 10 years old or sooner if they do not respond properly.
- Be sure the smoke alarm has the label of a recognized testing laboratory.
- Alarms that are hard-wired (and include battery backup) must be installed by a qualified electrician.
If cooking fumes or steam sets off nuisance alarms, replace the alarm with an alarm that has a “hush” button. A “hush” button will reduce the alarm’s sensitivity for a short period of time.
- An ionization alarm with a hush button or a photoelectric alarm should be used if the alarm is within 20 feet of a cooking appliance.
- Smoke alarms that include a recordable voice announcement in addition to the usual alarm sound, may be helpful in waking children through the use of a familiar voice.
- Smoke alarms are available for people who are deaf or hard of hearing. These devices use strobe lights. Vibration devices can be added to these alarms
- Smoke alarms are an important part of a home fire escape plan.
- If you have ceilings that are pitched, install the alarm near the ceiling’s highest point.
- Don’t install smoke alarms near windows, doors, or ducts where drafts might interfere with their operation.
- Never paint smoke alarms. Paint, stickers, or other decorations could keep the alarms from working.
