What age threshold triggers the replacement of a smoke detector?

What age threshold triggers the replacement of a smoke detector?

• A. 5 years
• B. 7 years
• C. 10 years
• D. 15 years

Answer: (C)

Smoke detectors are designed to ensure an effective response to smoke and fire threats, and as they age, their sensors can become less reliable. The established guideline is that smoke detectors should be replaced approximately every 10 years. This timeline is based on the degradation of the sensing technology and overall performance of the device over time. After 10 years, the reliability of the unit is significantly compromised, and it is advisable to replace it to maintain safety standards. Regular maintenance, such as testing and cleaning, should also occur throughout the life of the detector, but replacement after the 10-year mark is critical for ensuring optimum functioning and safety. Therefore, the age threshold triggering the replacement of a smoke detector is 10 years.
