NFPA 497 Fig 5.10.16
I noticed this in the 2017 edition. It's in the 2024 edition the same way.

1. Shouldn't this diagram list "Division 2" instead of "Zone 2"? 5.10 is for Divisions; 5.11 is for Zones. Is it a typo?
2. Assuming the section on the left is a view from above, the left shows a 15ft ground level radius, but the right side shows a 10ft radius. Am I looking at it wrong?
