Certified Fire Protection Specialist (CFPS) — Question 10

When constructing the foundation for a tank or tower installation, the compressive strength of the concrete should be not less than:

Answer options

• A. 1,000 psi (6.89 MPa)
• B. 2,000 psi (13.79 MPa)
• C. 3,000 psi (20.69 MPa)
• D. 4,000 psi (27.59 MPa)

Correct answer: B

Explanation

The correct answer is B because a compressive strength of 2,000 psi (13.79 MPa) is generally considered the minimum acceptable for the stability and safety of tank or tower installations. Options A, C, and D do not meet the minimum requirement, as they are either too low or higher than necessary for foundational support.
