Question 1 of 27070

A safety outlet is provided on the CO₂ discharge piping to prevent __________.

🔍 Key Concepts

• CO₂ fixed firefighting systems and how they discharge into a protected space • Purpose of a safety (relief) outlet or relief valve in any pressure system • Where the highest pressure risk actually occurs: in the cylinder, in the protected space, or in the piping

💭 Think About

• Think about what happens to pressure in the CO₂ piping the moment the system is activated and valves open or close. • Ask yourself: which part of the system needs a path to safely relieve excess pressure so that metal components are not damaged? • Consider the difference between protecting people in the space and protecting equipment from over‑pressure. Which one is the specific job of a safety outlet on discharge piping?

✅ Before You Answer

• Verify which component is being protected: cylinder, protected space, or discharge piping. • Distinguish between life-safety functions (protecting personnel) and mechanical protection (preventing rupture from over‑pressure). • Confirm that a safety outlet is a type of over‑pressure protection device and ask: over‑pressure of what, exactly, according to the wording of the question?
