During inspection, which aspect of sprinkler heads should be checked?

• A. Orientation, damage, obstructions, and cleanliness of protective caps
• B. Height of ceiling
• C. Temperature of water in supply
• D. Distance to the nearest wall

Answer: (A)

During inspection, focus on the protective caps of sprinkler heads and ensure they are ready to actuate. The cap should be intact, properly seated, and free of damage. Its orientation must match the head type (upright, pendant, or sidewall) so the spray pattern will be correct. The area around the head must be free of obstructions and the cap and head must be clean; debris, paint, dust, or other material can interfere with the heat-sensitive element or prevent proper release. A damaged or dirty cap or anything blocking the head can delay discharge or alter the coverage area. Other factors like ceiling height, water temperature in the supply, or distance to a wall aren’t part of the immediate condition of the head itself during this inspection.
