What should a building owner do if they notice faulty smoke detectors?

The correct approach for a building owner noticing faulty smoke detectors is to replace them and ensure they are functioning properly. Smoke detectors are critical safety devices that provide early warning in the event of a fire, thereby protecting lives and property. If they are faulty, they not only fail to alert occupants but can also create a false sense of security that leads to dangerous situations.

Replacing faulty detectors demonstrates a proactive stance in fire safety and compliance with safety regulations. It is important for building owners to regularly test and maintain smoke detectors as per local fire codes and standards. This includes ensuring that all detectors are operational, appropriately located, and equipped with fresh batteries if they are battery-operated.

By taking this action, the owner not only meets legal and safety obligations but also contributes to the overall safety of the building's occupants. The other options present either negligence or insufficient action that could compromise safety.
