Division 2 differs from Division 1 in what way?

Division 2 differs from Division 1 in what way?

• A. Higher safety factor
• B. Lower safety factor
• C. Same safety factor
• D. Longer construction time

Answer: (A)

Division 2 uses a more conservative design approach with greater safety margins than Division 1. This means the pressure boundary is designed and inspected under stricter rules, material and fabrication controls are tighter, and more rigorous analysis is required for critical or high‑risk applications. The overall effect is a larger factor of safety in Division 2 compared to Division 1, which is why it’s chosen for vessels where the consequences of failure must be minimized.
