How long should smoke alarms be replaced according to the information?

• A. every year
• B. every five years
• C. every ten years
• D. every fifteen years

Answer: (C)

Smoke alarms should be replaced every ten years because over time, the sensors inside them can become less effective at detecting smoke and fire. This lifespan recommendation ensures that the alarms remain reliable and functional in providing adequate safety. As alarms age, their mechanisms may degrade, making it crucial to adhere to this timeline for ensuring optimal performance and protection for occupants in case of a fire. Regular testing of smoke alarms is also advised, but it’s important to remember that the entire unit must be replaced after ten years, regardless of whether it appears to be functioning properly or not.
