What are some common causes of false alarms in smoke detectors?

• A. Water leakage
• B. Dust accumulation, steam, or cooking smoke
• C. Low battery power
• D. Improper installation

Answer: (B)

The choice identifies common environmental factors that can trigger a smoke detector erroneously. Smoke detectors are sensitive devices designed to detect the presence of smoke particles in the air, but they can also react to other elements that mimic smoke or create similar conditions. Dust accumulation can obstruct the sensor or create interference, leading the detector to interpret dust as smoke. Additionally, steam from cooking or high humidity levels can create vapor that sets off the detector, confusing it with smoke. Cooking smoke, especially from burnt food, is a well-known source of false alarms in residential settings. These factors highlight the importance of regular maintenance and situating smoke detectors in appropriate locations to minimize unnecessary alarms while still providing essential safety alerts when genuine smoke is present.
