Which statement about atmospheric-type storage tanks is correct regarding siting?

• A. They may be moved
• B. They shall be solidly mounted and permanently located
• C. They can be relocated
• D. They must be placed above ground only

Answer: (B)

The main idea here is that atmospheric-type storage tanks must be fixed in place to ensure reliable and safe operation of the foam system. They are required to be solidly mounted and permanently located so they won’t shift or be damaged by vibrations, handling, or accidental contact, which could affect the feed of foam concentrate and the integrity of the system. This permanence helps keep piping connections, vents, and control devices aligned and functioning as designed, and it supports safe maintenance and inspection. The other statements imply movement, relocation, or a specific placement above ground, which aren’t the criteria for siting under the standard; the key point is that the tanks are intended to remain in a fixed, stable position.
