Maine Journeyman Oil Fuel Board Rules Practice Test

The foundation for tank supports must be made of solid concrete due to its strength, durability, and ability to provide a stable base for the weight of the tanks. Concrete offers excellent load-bearing capabilities, ensuring that tanks are securely supported and won’t shift or settle over time, which could lead to leaks or structural failures. Furthermore, concrete is resistant to environmental factors such as moisture and corrosion, making it suitable for outdoor applications where tanks may be exposed to the elements.

Other materials like wood may not provide the necessary durability or resistance to decay and moisture over time. Steel, while strong, can rust and degrade if not properly treated or maintained, especially in the presence of fuels and oils. Plastic composites, while potentially resistant to certain chemicals, may not offer the same level of structural integrity or stability as solid concrete, particularly under heavy loads. Thus, solid concrete is the optimal choice for ensuring a safe and lasting foundation for tank supports.
