Which of the following locations is not recommended for smoke detector installation?

Smoke detectors are essential for safety, but their placement significantly impacts their effectiveness. The location where a smoke detector is installed matters because certain environments may lead to frequent false alarms or hinder the detector's performance.

In the context of the question, installing smoke detectors near bathrooms is not recommended primarily due to the high humidity and steam that can occur during showers and baths. This moisture can create false alarms or cause the sensor in the smoke detector to malfunction, reducing its reliability when it is actually needed.

When considering the other locations, installing smoke detectors near kitchens is generally discouraged because cooking often produces smoke, leading to false alarms. However, it is recommended to put them a certain distance from cooking appliances to minimize this issue. Smoke detectors in stairwells are crucial for alerting individuals in multi-story buildings, while utility rooms, depending on their function, can be safe zones for installation, provided they are not subject to excessive dust or heat.

Overall, the emphasis on avoiding installation near bathrooms stands out as it poses unique challenges that can affect the operation of smoke detectors.
