An overhead door manufacturer was cited a violation from the local AHJ stating that the Storage exceeded 12-ft.
The building in question has two warehouses protected by the same wet system. One side of the warehouse has an approximately 30-ft high ceiling, and the other side is approximately 20-ft high.
The lower side stores doors up to 12-ft in height, on pallets or dunnage in cardboard with strapped packaging. Most of this is straight off the flow without any racking. On small racking unit along the wall with a mixture of cardboard boxes.
The higher ceiling has a few cantilever style racks with overhead doors wrapped in either plastic or cardboard while being strapped. It also has a single-row rack with boxes on conventional pallets. The bottom row has plastic pallets.
The existing system is currently designed for Ordinary Hazard Group 2.
What classification should this storage fall under? Is OH2 appropriate given the heights and contents?
Are there further evaluations that would need to be had to arrive at the hazard classification for this?
Thanks in advance.
