Thks for clarification.
I deduce this storage area is not currently involved with anyone's BRC-related activities.
From BRC's POV, the storage stage within a manufacturer's production plan is typically auto-included within their scope of "Production" since it will presumably be on the manufacturer's production flowchart. The storage is usually BRC-designated as an "Enclosed area" of relatively low risk of contamination.
Not sure if you know (?) but BRC offer a variety of FS Standards other than Manufacturing, eg Storage/Distribution, Agent-Brokering. The relevance will depend on yr specific intentions/options. Their detailed requirements for each situation are spelled out in the (afaik free) downloadable Standards from BRC website.
It all depends on what you want to do.
