What distance must power cables permit parking the power unit away from fuel servicing vehicles?

Explanation:
The key idea is keeping electrical power units away from fueling operations to prevent ignition hazards from fuel vapors and electrical sources. Fuel vapors can travel along surfaces and accumulate near fueling areas, so if a power unit or its cables produce a spark, arc, or hot surface, ignition could occur. A fifty-foot separation provides a safe margin for vapors to dissipate and for personnel to work without risking damage to cables or contact with fueling equipment. Shorter distances raise the risk of ignition or cable damage, while a much larger distance isn’t typically required for normal operations.
