How can dust accumulation affect a smoke detector's performance?

• A. It improves sensitivity
• B. It has no effect
• C. It can hinder smoke sensing
• D. It makes the detector louder

Answer: (C)

Dust accumulation can significantly hinder the performance of a smoke detector by obstructing the sensor's ability to detect smoke particles in the air. When dust builds up inside or on the sensor surfaces, it creates a barrier that can prevent smoke from reaching the sensing elements. As a result, the detector may fail to respond to smoke, thereby compromising its primary function of alerting occupants to smoke or fire hazards. Regular cleaning and maintenance of smoke detectors are essential to ensure that they operate effectively and maintain their sensitivity to potential fire situations. This understanding reinforces the importance of routine maintenance practices in fire safety protocols.
