Fire Department Incident Safety Officer Practice Test

What feature distinguishes Type V building construction from other types?

1. Use of non-combustible materials

2. Entirely made of metal

3. Reliance on wood framing

4. Exclusive use of masonry

The correct answer is: Reliance on wood framing

Type V building construction is characterized primarily by its reliance on wood framing. This type of construction typically utilizes wood for the structural framework, which can include elements like walls, floors, and roofs. The significance of this feature lies in the combustible nature of wood, which greatly influences fire behavior and safety considerations. In contrast to other construction types, which may integrate more non-combustible materials or rely on metal or masonry, the wood framing in Type V construction poses different risks and challenges during a fire incident. It's important for safety officers to recognize that the combustible nature of wood can lead to faster fire spread and structural failure when compared to buildings made primarily of non-combustible or fire-resistive materials. Therefore, understanding that Type V construction is framed with wood helps inform safety measures and tactics during firefighting operations.
