Fire Department Incident Safety Officer Practice Test

What is the primary fire hazard associated with Type V construction?

1. Electrical hazards

2. Structural collapse

3. Combustibility and rapid fire spread

4. Explosive materials

The correct answer is: Combustibility and rapid fire spread

The primary fire hazard associated with Type V construction is its combustibility and rapid fire spread. Type V construction typically involves lightweight, wooden materials that are more susceptible to ignition and can burn quickly when exposed to flames. This type of construction often features wooden framing, sheathing, and interior finishes, all of which can contribute to a fire's rapid development and spread throughout the structure. In residential structures, for instance, the limited fire-resistance rating of the materials used can lead to quicker structural compromise. Once a fire ignites, the potential for rapid engulfment increases due to the interconnected nature of the framing, allowing flames to move swiftly from one area to another. This characteristic constitutes a significant hazard during firefighting operations, as the danger of flashover and structural failure heightens under these conditions. Understanding the behavior of fires in Type V construction is crucial for firefighter safety and effective incident management.
