What is the minimum required distance a storage tank must be from any potential source of ignition?

The minimum required distance a storage tank must be from any potential source of ignition is two feet. This requirement is designed to minimize the risk of fire or explosion that could result from a leak or spill of flammable liquids that may occur in or around the tank. By maintaining this distance, the potential for ignition sources, such as heaters, motors, or other electrical equipment, to trigger a fire in the presence of flammable vapors is reduced.

Considering safety regulations and best practices, this two-foot distance acts as a critical buffer, ensuring that even in the event of a malfunction, the chance of an ignition event is significantly lowered, thus protecting both human life and property. This standard reflects broader industry practices aimed at fostering safe storage and handling of fuel and flammable liquids.
