Always approach storage vessels at ______ degree angles, NEVER from the ends or at right angles to them.

• A. 30
• B. 45
• C. 60
• D. 90

Answer: (B)

Approach at a 45-degree angle because this stance reduces your exposure if the vessel vents or ruptures and gives you a better view of openings, valves, and indicators. Coming from the ends or directly perpendicular to them puts you in the most likely path of a sudden discharge and limits your visibility and mobility to retreat. The 45-degree angle keeps you out of that direct line, while still staying close enough to observe and control the situation.
