How far must buildings with non-fire resistive walls be located from a point of transfer?

Buildings with non-fire resistive walls must be located at least 25 feet from a point of transfer, which typically refers to where propane is transferred from a bulk tank to smaller storage tanks or cylinders. This distance is established to mitigate the risk of fire and explosions, as non-fire resistive walls do not offer adequate protection in the event of a leak or fire. By maintaining a safe distance, it helps ensure that any potential hazards associated with propane transfer operations do not directly impact the structure, thereby enhancing safety for occupants and reducing the risk of property damage.

This safety regulation takes into account the flammability of propane and establishes protocols to protect both personnel and property in the vicinity of propane operations. Other distances listed in the options may not provide sufficient safety margins based on industry standards for hazardous material handling and local regulations.
