What could happen if a smoke detector is not properly maintained?

If a smoke detector is not properly maintained, it might stop working during an emergency, which is critical for ensuring safety. Smoke detectors rely on their sensors and mechanisms to detect smoke effectively. Regular maintenance, such as cleaning and testing, ensures that these devices remain in optimal condition and responsive to smoke. When dust, debris, or other obstructions accumulate, the detector could malfunction, leading to failure in alerting occupants to a fire—which could have devastating consequences. The importance of maintaining smoke detectors cannot be overstated, as they are vital tools for life safety in the event of a fire. Ensuring that they are functional and reliable is essential for providing accurate warnings during emergencies.
