What is a major hazard of a Type V construction building under fire conditions?

In Type V construction, the framing is wood and highly combustible, so the interior structure can burn away quickly even while the exterior walls look relatively intact. The major danger is interior collapse—the load-carrying members inside the building (studs, joists, plates, and floor/ceiling assemblies) can burn and fail, causing the floors and roof to give way from the inside. This collapse often happens with little warning because it originates within the concealed spaces and load paths, making firefighters and occupants unaware of the shifting support until the structure suddenly drops. Other hazards, like glass breaking or debris from a localized or outward collapse, can occur, but they are not the primary, defining danger in a Type V fire. The interior collapse represents the most serious risk because it directly involves the loss of the building’s internal support and can trap occupants or firefighters inside.
