Safety (flashover prevention) Devices for Insulative Tools
The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:
1. A safety device in combination with an elongated insulative tool of a certain length extending between a user end arranged to be contacted by a worker and a working end arranged for operation near energized equipment and having a substantially circular cross section defining a cross sectional diameter and an outer circumference, the device being arranged to substantially modify an electrical field along a length of the insulative tool such that a field strength at the user end of the insulative tool is reduced and the device comprising: a body defining an inner opening receiving the insulative tool therethrough; the body spanning generally radially outwardly from the inner opening to lie transversely to a longitudinal direction of the insulative tool received therethrough; the body consisting of a material which is either semi-conductive or conductive; the body having an outer circumference which is between two times and five times greater in magnitude than the outer circumference of the elongated insulative tool; and the body being positioned nearer to the user end of the insulative tool than the working end of the insulative tool.
