At Res-Q-Jack, Inc. we understand how to combat the threat of electric shock during vehicle stabilization.   The risk of electric shock with hybrid vehicles has been reported to be quite minimal.  Hybrid vehicle design has many fail-safe mechanisms in place to protect the firefighter from electric shock.  The real risk of electric shock during vehicle rescue is most likely downed power lines.  However, sometimes we want a little extra confidence.  With these potential risks in mind, Res-Q-Jack has developed a new strut head with a non-conductive coating**.

Rescue Struts made of non-conductive tubing extensions with steel heads are not the answer!  When a rescue strut with a steel swivel head is used to engage a vehicle, the rescuer often holds the head with his hand to ensure appropriate engagement.  The path to ground would be: vehicle to strut head, strut head to firefighter, and firefighter to ground.  What good does non-conductive tubing do here?  We believe the answer is to make the portion of a stabilization strut that contacts the vehicle non-conductive.  The item that contacts the vehicle is the head so that’s where we need protection.  So whether you are using our standard Res-Q-Jack steel struts or our new composite struts, you need insulated strut heads to aid in protecting from electric shock.
** The dielectric strength of the coating on Res-Q-Jack Insulated Strut Heads is about 300 V/mil (Volts/.001”).  An 1/8” (.125” or 125 mil) thick sheet of this material will provide a barrier that will not conduct electricity up to 37,500 Volts.  It is assumed that strut head is dry and that strut head is only portion of strut that is touching vehicle.  Base restraints must be non-conducting.  Rescuers must wear insulated gloves.   Always Check for electric hazards and eliminate hazard before attempting any contact with vehicle.
