ABSTRACT:
A non-conductive safety line and method for producing the safety line is disclosed. The safety line of the preferred embodiment comprises a rope core which has an exterior tubing positioned over the rope core with a quantity of filler material contained within the exterior tubing to completely capsulate the rope core. End loop splices are formed on the rope core ends and a pair of shrinkable tubing sections are positioned over the end loop splices. The completed safety line has a film applied to the exterior thereof to prevent surface wetting. The safety line may be used in conjunction with aerial buckets or hot boards from a lineman's body belt to the boom of an aerial lift or platform of an insulated hot board. The line maintains dielectric integrity, wet or dry, preventing shorting of the lineman's insulation from ground as conventional safety lines can do. The method disclosed teaches the formation of the safety line and the application of the filler to the inside of the exterior tubing surrounding the rope core and the ultimate curing of the safety line in a predetermined position as desired by the user.
