🚨 Why Do Old Smoke Detectors Turn Yellow? 🚨
Take a look at this smoke detector. Notice the yellow color?
Many smoke detectors are made from a special flame-retardant plastic that naturally yellows over time as it's exposed to heat, sunlight, and the aging process. While yellowing often suggests the detector has been around for a long time, color alone doesn't tell you when it should be replaced.
🔍 Here's what really matters:
✅ Check the manufacture date on the back or side of the detector.
✅ Replace smoke detectors that are 10 years old or older.
✅ Test your smoke alarms monthly.
✅ Replace batteries annually, or follow the manufacturer's recommendations if your detector has a sealed 10-year battery.
Smoke detectors are one of the most important safety devices in your home. Taking a minute to check their age could make all the difference in an emergency.
Stay safe, and don't forget to check the date—not just the color!
