What is the minimum distance required between LPG storage tanks and other flammable liquids storage tanks?

The minimum distance required between LPG (liquefied petroleum gas) storage tanks and other flammable liquids storage tanks is generally established to enhance safety and reduce the risk of fire or explosion in case of a leak or accident. The correct answer reflects safety regulations and guidelines from authorities that outline spacing requirements for the storage of flammable substances.

Maintaining a distance of 20 feet helps to create a safer environment by ensuring that in the event of an incident involving one type of flammable material, there is minimized risk of it spreading to another flammable material. This distance allows for sufficient space that can help prevent heat transfer and provide access for emergency responders if needed.

Other potential distances may not be adequate to provide that level of safety and reliability, which is why the regulation specifies 20 feet as a standard requirement for this particular situation.
