Occupancies including bulk petroleum facilities, and parking garages, are classified as:

• A. Target hazards
• B. Business occupancies
• C. Storage occupancies
• D. Mercantile occupancies

Answer: (C)

Occupancy classifications are about the primary use of the space. A storage occupancy is defined as a space whose main purpose is to store goods, materials, or vehicles. Parking garages fit this since their primary function is to store vehicles. Bulk petroleum facilities fit as well because they store large quantities of flammable liquids. The key idea is that the space is designed for storage, not for serving customers (mercantile), conducting offices or business activities (business), hosting gatherings (assembly), or manufacturing (factory/industrial). So, these facilities are categorized as storage occupancies, with any additional fire code considerations for hazardous materials applied on top of that base classification.
