Certified Fire Protection Specialist (CFPS) — Question 36

The nature of the mechanical systems is to use networks of pipes and ducts to connect various parts of the building. Even when the systems are off, these networks can provide routes through the building that allow the spread of fire, smoke, and biological or chemical compounds, causing the danger to spread beyond the hazard's origin. Which of the following is considered to be a building design element that can limit the likelihood of such a system from spreading fire, smoke or chemicals through a building?

Answer options

• A. Open-loop systems
• B. Automatic dampers
• C. Common duct networks
• D. Defensible space

Correct answer: D

Explanation

Defensible space is a design concept that creates physical barriers to deter the spread of fire, smoke, or hazardous materials, making it the correct answer. In contrast, open-loop systems, automatic dampers, and common duct networks do not inherently limit the spread of these dangers and may even facilitate it instead.
