In areas with obstructions, how should sprinkler spacing be adjusted?

Increase coverage based on guidelines

In areas with obstructions, increasing coverage based on guidelines is essential to ensure effective fire protection. The presence of obstructions can inhibit the proper distribution of spray from the sprinkler heads, which can lead to inadequate coverage of areas that require protection.

By following established guidelines for adjusting sprinkler spacing in obstructed areas, it becomes possible to ensure that fire suppression efforts are not compromised. These guidelines typically suggest modifying the placement and distance of sprinklers to account for the impact of obstructions, allowing for a more comprehensive and effective coverage pattern. This approach helps to minimize potential fire hazards by ensuring that all areas are adequately protected despite physical barriers that may disrupt the water spray from the sprinklers.

The other options may not effectively address the unique challenges posed by obstructions in a space.
