What minimum vertical clearance must an above-ground propane tank maintain from overhead electrical lines rated at 600 volts or more?

• A. 4 feet
• B. 8 feet
• C. 10 feet
• D. 6 feet

Answer: (D)

Maintaining a safe distance from overhead lines is essential to prevent arcing and ignition risk when a propane tank is nearby. For lines rated at 600 volts or more, the minimum vertical clearance used in this context is six feet. That six-foot buffer helps ensure there’s enough room for the tank, hoses, and any equipment you’re using to stay clear of the energized conductors, even if lines sag a bit or weather shifts the setup. If you ever find you can’t meet that distance, you should pause work and coordinate with the utility to de-energize the line or provide proper protection, rather than attempting to work closer.
