What materials are prohibited in the construction of fuel oil storage tanks?

The selection of untreated wood and reactive or combustible materials as prohibited in the construction of fuel oil storage tanks is rooted in safety and compliance with industry standards. Untreated wood is susceptible to corrosion, decay, and failure when exposed to oil, which can lead to leaks and environmental hazards. Additionally, utilizing reactive or combustible materials in the construction of fuel oil storage tanks poses significant risks, as these materials could ignite or react dangerously in the presence of fuel oil or during storage conditions, potentially causing fires or explosions.

In contrast, steel and concrete are commonly used in tank construction due to their strength and durability, and high-density plastic is often acceptable due to its resistance to corrosion and chemical stability. Composite materials can also be permissible if specifically designed and tested for such applications. Thus, the prohibition of untreated wood and reactive or combustible materials underscores the emphasis on safety and integrity in fuel oil storage tank construction.
