Duct with electrically conductive coating

A duct (20) includes a polymeric duct wall (22) that circumscribes a fluid-conveyance passage (24). The polymeric duct wall (22) includes, relative to the fluid-conveyance passage (24), an inner surface (22a) and an outer surface (22b). An electrically conductive coating (26) is disposed on at least one of the outer surface (22b) and the inner surface (22a).
