Tanks must be covered with at least how many feet of earth for protection?

The requirement for covering tanks with a certain amount of earth is crucial for ensuring safety and environmental protection. Covering tanks with at least 1 foot of earth creates a barrier that helps shield them from physical damage and external hazards such as impacts or exposure to harsh elements. This layer also contributes to thermal insulation, which can help maintain the integrity of the substance stored within the tank.

Additionally, this depth aids in preventing unauthorized access, which is an important safety consideration. The coverage depth works in conjunction with regulations that take into account factors like soil type and local climate conditions, ensuring that tanks are adequately protected regardless of their surrounding environment.

While other depths might be considered in certain contexts, the standard of 1 foot is established to strike a balance between adequate protection and practical considerations for installation and maintenance.
