According to sprinkler spacing guidelines, the distance from sprinklers to walls must not exceed which fraction of the allowable distance between sprinklers?

In the context of sprinkler spacing guidelines, the distance from sprinklers to walls is vital for ensuring proper water distribution and effectiveness of the sprinkler system. The correct fraction that specifies how far from walls sprinklers can be placed, relative to the allowable spacing between the sprinklers themselves, is 1/2.

This means that the distance from a sprinkler head to the nearest wall should not exceed half of the maximum allowable distance between two sprinkler heads. This guideline is designed to guarantee that water is effectively sprayed across the area and that there are no dry spots due to inadequate coverage near walls. If the distance to walls were any greater than this fraction, it could lead to an ineffective sprinkler pattern, ultimately compromising fire protection in that area.

In a broader understanding, this guideline ensures that the sprinklers can perform as intended during a fire event, providing optimal coverage and contributing to overall safety.
