Which feature of a building enhances resilience to fire hazards?

• A. Use of non-combustible materials
• B. Lack of fire exits
• C. Complex roof structures
• D. Lightweight construction

Answer: (A)

Using non-combustible materials significantly enhances a building's resilience to fire hazards. These materials do not ignite or burn easily, which reduces the likelihood of fire spread within and between structures. Examples include concrete, brick, and steel, which serve to contain fires and allow occupants more time to evacuate and firefighters more time to respond.

In contrast, the other options present factors that compromise a building's fire safety. The absence of fire exits can trap occupants during an emergency, complex roof structures can create challenges for fire suppression and contribute to the rapid spread of flames, and lightweight construction materials are often more susceptible to burning quickly, potentially leading to catastrophic structural failure under fire conditions. Thus, the choice of materials plays a critical role in overall fire safety and resilience.
