The bottles must be mounted in such a manner that should an explosion or failure of any mechanical component of the vehicle occur, the bottles will be protected from flying parts. Also,the position of the bottles in the vehicles must be high enough that they cannot come into contact with the track surface following loss of a tire of wheel. They should be protected from excessive temperature and mounted rigidly to the vehicle. Remote cables must be metallic (plastic or plastcu-wrapped cables are prohibited) and installed so they are protected in the event of an upset or collision. Follow the manufacturer's recommendations regarding installation, especially on bend radius and protection from crimping or kinking.

Sidebar must be included on driver's side. The side bar must pass the driver at a point midway between the shoulder and elbow. All vehicles with OEM frame must have roll bar welded to frame. Installation of from connectors on uni-body cars does not constitute a frame and therefore it is not necessary to have the roll bar welded to the frame.

All chrome molly welding must be done by approved TIG Heliarc process. Mild steel welding must be approved wire feed process (MIG or TIG). Welding must be free of slag and porosity.
