Fire Department Incident Safety Officer Practice Test

Which construction method in Type V buildings contributes to faster deterioration during a fire?

1. Synthetic materials

2. Wood framing

3. Precise engineering

4. Heavy masonry

The correct answer is: Wood framing

Wood framing is a key characteristic of Type V buildings, which are typically constructed using lightweight, combustible materials. This construction method utilizes wood as the primary structural framework, making it particularly susceptible to combustion when exposed to fire. During a fire incident, wood can ignite quickly and burn at a rapid rate, leading to faster deterioration and potential collapse of the structure. The characteristics of wood framing contribute to the scenario in which the fire can spread more easily, as wood allows flames to consume the material and release heat into the surrounding areas. This not only poses risks to the immediate integrity of the structure but also heightens the danger to responders due to the unpredictability of the burning wood. In contrast, synthetic materials, while potentially problematic, do not inherently contribute to faster deterioration of the building’s structural integrity in the same way that wood does. Precise engineering may enhance the overall design and safety features, while heavy masonry, being non-combustible, offers greater resistance to fire and does not deteriorate as quickly as wood framing.
