Considering the value of fire apparatus, I wouldn’t short cut the criteria. I’d do no less than OH2. Honestly I would be curious to see how an OH criteria was deemed adequate for an Apparatus Bay.
Want another zinger? EV Fire Apparatus. You can throw your OH criteria out the window.

The apparatus bays of a fire station have been designated on the plan as ordinary hazard, group 1. When I look at the examples in §A.4.3.3.2, it seems to me that those spaces would be similar to (2) "automobile parking garages", or (14) "machine shops", or (24) "repair garages." This would make the space similar to ordinary hazard group 2, which increases the required density from 0.15 gpm/ft² to 0.20 gpm/ft². Am I looking this incorrectly?
