What is the minimum distance for clearance of combustible materials from outdoor tanks?

The minimum distance for clearance of combustible materials from outdoor tanks is 25 feet. This requirement is established to ensure safety around flammable and combustible liquids, as the proximity of combustible materials can significantly increase fire hazards. Maintaining a distance of 25 feet helps to minimize the risk of ignition and allows for adequate space for firefighting operations, should an emergency arise. This distance is aligned with industry standards designed to protect both the tanks and surrounding structures from potential fire spread, ensuring a safer environment. Planning for this clearance is vital in fire and safety management practices, where the control of potential sources of ignition in relation to storage tanks is critical.
