What characterizes Type V construction?

Type V construction is characterized by its use of combustible materials, primarily wood. This construction type includes buildings where the major structural elements, such as walls, floors, and ceilings, are made of wood or other similar materials that are not fire-resistant. This has significant implications for fire behavior and the overall fire risk associated with Type V structures.

The reliance on these materials means that fires can spread rapidly, as they ignite easily and can burn quickly. This construction type is commonly found in residential buildings, especially single-family homes and townhouses where cost-effectiveness and accessibility of materials are priorities.

In contrast, the other options describe characteristics of different construction types. For example, buildings made entirely of steel belong to Type I or Type II categories, which emphasize its non-combustible nature, while masonry walls are more aligned with Type II, III, or IV constructions. Heavy timber elements are often associated with Type IV construction, which allows for increased structural stability but does incorporate some combustible elements. Understanding these distinctions is crucial for fire fighters when assessing hazards and planning response strategies.
