RP400 — Hanging Hardware Continuity (2023 ed.)

A plain-language orientation to electrical-continuity testing of fuel-dispensing hanging hardware

What This Topic Covers
  • The general subject of confirming that fuel-dispenser hanging hardware maintains a continuous electrical path
  • Hanging hardware: the hoses, breakaway couplings, swivels, and nozzles that hang from a dispenser
  • Why a continuous path lets static electricity dissipate safely instead of building up
  • How this area relates to — but does not replace — fire-safety codes and manufacturer requirements
Why It Matters
  • Static electricity that cannot dissipate can create a spark at the dispenser
  • A spark during refueling is a recognized fire-ignition hazard
  • Verifying continuity helps keep the dispensing area safe
Who Uses It
  • Owners and operators of fuel-dispensing facilities
  • Service technicians maintaining dispensers and hanging hardware
  • Fire and compliance inspectors evaluating a site
Regulatory Context
  • Fueling-area fire safety is addressed by codes such as NFPA 30A and adopted state and local fire codes
  • Equipment manufacturers also specify continuity expectations for their hardware
  • Industry recommended practices offer guidance on how continuity is checked
