According to NFPA 58, vertical tanks shall be designed to withstand the _____ anticipated at the sites.

• A. Humidity
• B. Rainfall
• C. Wind, High Winds, and Seismic Forces
• D. Snow Load

Answer: (C)

The main idea is that vertical propane tanks must be built to resist the actual environmental forces they’re likely to face at their location. NFPA 58 requires these tanks to be designed for the anticipated wind loads at the site, including high winds, and for seismic forces. This is because strong winds and ground shaking can cause lateral movement, tipping, or structural failure if the tank isn’t properly anchored and supported, which could lead to leaks or spills with serious safety consequences. Humidity and rainfall aren’t the primary structural design loads addressed for these tanks, and while snow load can matter in some climates, the standard emphasizes wind and seismic forces as the decisive design factors.
