Which hazard is most associated with Type V (wood frame) construction?

• A. Rapid fire spread
• B. Slow fire growth
• C. No hazards
• D. Fire resistance

Answer: (A)

Wood frame construction uses readily combustible materials and often has open framing with many concealed spaces. When a fire starts, these factors allow flames to travel quickly through studs, joists, and voids, driving rapid fire spread and early structural involvement. Because the framing itself contributes fuel and there’s typically limited inherent fire resistance, the hazard most associated with this type is rapid fire spread. While protective measures can improve fire performance, a standard wood-frame building is not inherently fire-resistant, and slower growth or no hazards aren’t accurate descriptions of its typical behavior.
