How far from walls must sprinklers be installed in light hazard areas?

• A. 2 feet
• B. 4 feet
• C. 6 feet
• D. 8 feet

Answer: (B)

In light hazard areas, sprinklers must be installed a minimum of 4 feet from the walls. This requirement is established to ensure that the spray pattern of the sprinkler can fully cover the area without obstruction and provide adequate fire protection. The distance from the wall allows the water to disperse effectively, maximally covering the space that could potentially catch fire. By adhering to this spacing, it eliminates dead spots where the sprinkler's water discharge might not adequately reach, ensuring that the system operates efficiently in extinguishing or controlling fires. This is crucial in light hazard areas, where quick fire response is essential because of the types of materials stored or used, often being less combustible compared to higher hazard categories.
