What is the distance from the FZB to the Quick Disconnect Fittings?

• A. 10 ft
• B. 5 ft
• C. 15 ft
• D. 20 ft

Answer: (A)

Maintaining proper clearance between the Fire Zone Boundary and Quick Disconnect Fittings is about ensuring safety and operability: you need enough room to reach, connect, and disconnect the fittings without crowding the area or forcing awkward, unsafe motions near the hazard boundary. Ten feet gives a practical balance. It provides enough space to stretch and maneuver the hose and coupling under typical conditions, while keeping you clear of the boundary and away from heat, splash, or entanglement risks. It also fits with standard hose layout and stowage practices, avoiding excessive length that could create clutter or tripping hazards.

Choosing a shorter distance makes deployment and disconnection cramped and more error-prone. A much longer distance adds unnecessary hose length, which can complicate handling, storage, and line management without adding meaningful safety benefits. So ten feet is the most workable, safety-conscious compromise.
