According to NFPA 72, where should smoke detectors be installed in a residential setting?

1. In every room

2. In every kitchen

3. In every bedroom

4. In every hallway

The correct answer is: In every bedroom

The correct choice emphasizes that smoke detectors should be installed in every bedroom as per NFPA 72 guidelines for residential settings. This recommendation is based on the understanding that bedrooms are spaces where people sleep, and having a functioning smoke detector in this area is critical for early warning in the event of a fire, ensuring occupants have sufficient time to react and evacuate safely. It's also important to note that while smoke detectors in living areas and hallways contribute to overall safety, the unique risk posed when individuals are sleeping underscores why detection in bedrooms is prioritized. Placement in common areas, such as hallways, is essential, but ensuring coverage in the place where people typically are not aware of a fire - during sleep - is vital. This focus on bedrooms enhances safety, as it can significantly increase the likelihood of alerting residents to danger when they are most vulnerable.
