A low-hazard storage is classified as which occupancy?

In building codes, specifically the International Building Code (IBC), low-hazard storage is typically classified under Group S occupancies, which encompass storage facilities. The Group S division is further divided into three categories based on the nature of the stored materials and their associated hazards.

Group S-1 is designated for moderate-hazard storage, including materials that pose a greater risk than those in low-hazard conditions, whereas Group S-2 is classified for low-hazard storage. This means that materials stored in a Group S-2 occupancy are generally non-combustible or present minimal risk in terms of fire and safety concerns.

The choice of Group S-2 is correct because it accurately represents storage conditions where the risk to life safety and property due to hazards in storage is low, aligning perfectly with the definition of low-hazard storage. This helps ensure proper design, construction, and safety requirements, ultimately protecting occupants and property in the built environment.
