What is the maximum distance from the wall for sprinkler spacing?

1. 1/4 the required spacing

2. 1/2 the required spacing

3. Equal to the required spacing

4. Twice the required spacing

The correct answer is: 1/2 the required spacing

The maximum distance from the wall for sprinkler spacing is 1/2 the required spacing. This guideline is crucial for ensuring that water coverage is effective and that the sprinklers can adequately protect the space against fires. When installing sprinklers, the effectiveness of distribution and the ability to provide adequate coverage is paramount. Limiting the distance from the wall to half of the required spacing helps prevent water from missing areas close to the walls, which are often critical points to cover. This approach ensures that those areas receive sufficient water in the event of a fire, minimizing potential hazards. Sprinkler coverage must be designed with safety as a priority, and understanding these spatial limitations helps in creating effective fire protection systems. In contrast, other options present distances that could lead to inadequate coverage or overspreading, increasing the risks during a fire incident.
