The year was 1999 and my task was to complete an inspection of various existing sprinkler systems in a large multi-story warehouse. I’m aware that all that is required of those on inspection is normally a walk-through visual inspection (NFPA 25:1998/2-2.2: “Sprinkler pipe and fittings shall be inspected annually from the floor level.”). However, I occasionally like to stand on a ladder or chair and spot-check above the ceiling, especially when combustible construction is involved.
I stared at this curiosity for a bit and then looked at the building engineer. “That’s a bad head,” he said. Hmmm, more like bad consumer logic, and apparently a deferred maintenance issue.
