A Top 10 of Reasons Why Smoke Detectors Commonly Go Off…..


There is no secret of the importance of having smoke detectors throughout your home or business.


Whether battery operated units or units that are hard-wired to the local fire department should they be set off, their purpose is the same:


To alert us as quickly as possible if there is a potential fire in the area where the smoke detector has been set up.

The intent of smoke detectors is obviously to help save as many lives as possible in the event of a fire, here is a quick ‘Top 10’ list of the most common reasons a smoke detector’s alarm is triggered:



  1. Burning food on the stove
  2. Smoke from the fireplace
  3. High humidity
  4. Insects
  5. Burn toast
  6. Low batteries
  7. Chemical odors
  8. Dust
  9. Steam
  10. An actual fire!

Knowing the above can help you perhaps stay ahead of the game and limit your smoke detector from going off for reasons other than true emergencies.

Obviously if there is an actual fire, I am sure we all want the smoke detector blaring as annoyingly possible.

Short of an actual fire though, I believe most people would rather limit the number of times the sound of the smoke detector alarm occurs.

Simple things such as making sure that the toaster is not located directly under a smoke detector or that your smoke detector batteries are changed out frequently (to avoid the maddening “chirping” that can occur as the batteries gradually run their useful life) can be helpful in limiting your smoke detector’s alarm from sounding.

Other things may not be as controllable (such as a random insect somehow getting into the smoke detector and setting the alarm off).

Whether easily preventable or not, I am hoping this list may be helpful in providing some type of guidance as to the variety of things that may be responsible for activating the blaring alarm of a smoke detector in your home or business.
