How far apart should two above-ground tanks be spaced?

The spacing requirement for two above-ground tanks is crucial for safety and compliance with regulatory standards. The correct answer, which specifies a distance of 3 feet, is based on guidelines aimed at minimizing risks associated with potential leaks, spills, or fires. Maintaining this distance helps ensure that any adverse incidents involving one tank do not readily affect the other, providing a buffer zone that can limit the spread of hazards.

This spacing also allows for safe access for inspections, maintenance, and emergency responses, contributing to overall operational safety. In certain regulatory frameworks, maintaining adequate spacing between tanks is a vital aspect of risk management to prevent catastrophic events that could arise from tank failures.

Options indicating a spacing of 1 foot, 2 feet, or 4 feet do not meet the recommended safety standards as effectively as the established 3-foot distance, which balances both safety and practical access needs.
