Apparatus for detecting an electrical insult to a gas tubing system and dissipating the energy from such insult. The system includes tubing and an injury mitigator. The tubing includes a conduit, an insulating layer, a conductive layer, and a jacket. The conduit is connected to earth ground. The conductive layer is electrically insulated from the conduit by the insulating layer. The mitigator includes an insult event detection circuit and an energy dissipation circuit, both electrically connected between the conductive layer of the tubing and ground. Insult indication is provided by a fusible link. Energy dissipation is provided by the fuse, a transient voltage suppression (TVS) device, and/or a spark gap. The TVS device has a setpoint voltage less than the breakdown voltage of the spark gap, ensuring that the TVS device actuates before the spark gap conducts.
