Abstract: This invention relates to the pipeline safety system. The invention is a warning alert system for presence of an induced AC voltage/current on a pipeline system that runs in parallel with an AC transmission line. This invention is a warning alert system for ground faults from power high voltage AC systems which can induce AC voltage/current onto a piping system.

Abstract: The present invention relates to a safety mechanism for holiday detectors. When a user properly holds a holiday detector, a safety button is engaged which allows the holiday detector to be turned on. If the safety button is not engaged, the holiday detector cannot be turned on. The holiday detector then remains on only as long as the safety button is engaged. In other embodiments of the invention, a lanyard connects a safety switch on the holiday detector to the user. If the user were to drop the holiday detector, the lanyard would flip the safety switch thus shutting off power to the holiday detector.
