How much space should be provided between each smoke detector within a corridor?

1. 20 feet

2. 30 feet

3. 40 feet

4. 50 feet

The correct answer is: 30 feet

The standard spacing of smoke detectors within a corridor is crucial for ensuring that smoke is detected in a timely manner during a fire emergency. The generally accepted guideline is to position smoke detectors no more than 30 feet apart in corridors. This spacing helps to create a reliable detection area, minimizing the risk of smoke getting past a detector unnoticed. When smoke detectors are installed close together, there is a heightened chance that they will pick up smoke quickly, alerting residents and staff effectively. Proper placement also helps reduce the likelihood of false negatives, which can occur if detectors are too far apart. Based on these guidelines, the recommendation of having smoke detectors spaced 30 feet apart is designed to balance coverage and sensitivity, contributing to the safety of a nursing home environment.
