ABSTRACT:
A guard for preventing movement of a handle by an operator from a locked position to a second position. The handle is coupled to an operating mechanism which controls a distribution device. The handle extends outwardly from the surface of the distribution device. The guard includes a cover which is configured to substantially enclose the handle while in the locked position. The cover is supported about the handle by abutting the surface of the distribution device. The cover is also configured to allow the handle to move from the locked position to the second position wherein the cover prevents an operator, but not the operating mechanism, from moving the handle from the locked position to the second position and the handle positively indicates the state of the operating mechanism between the positions. The guard also locks the cover to the distribution device. The present invention also a method of positively indicating the state of an operating mechanism controlling a distribution device while simultaneously preventing movement of a handle coupled to the operating mechanism by an operator from a locked position to a second position. The handle is coupled to an operating mechanism which controls a distribution device. The handle extends outwardly from the surface of the distribution device.
