I understand per guidance in the annex of NFPA 13 (2016 edition, A.5.3.2(25)) stages are an example of an OH2 hazard, but would this apply in an auditorium/theater with a platform (no curtains)?
220.127.116.11 Ordinary hazard (Group 2) occupancies shall be defined as occupancies or portions of other occupancies where the quantity and combustibility of contents are moderate to high, stockpiles of contents with moderate rates of heat release do not exceed 12 ft (3.7 m), and stockpiles of contents with high rates of heat release do not exceed 8 ft (2.4 m).
A.5.3.2 Ordinary hazard (Group 2) occupancies include occupancies having uses and conditions similar to the following: (25) Stages
I'm not quite clear why a stage is considered an ordinary hazard instead of a light hazard.
