ABSTRACT:
A rubber insulating blanket of a type used by workers, such as electrical lineworkers and industrial electricians, to cover live electrical conductors, apparatus, or circuits, so as to protect themselves against electrical shock hazards, is generally square or otherwise generally rectangular, so as to have two longitudinal edges and two transverse edges. The blanket is provided with four handles, each of which is located at the middle of a separate edge of the blanket. If the blanket has eyelets located near the middles of the longitudinal edges, the eyelets so located are located between the handles located at those same portions. Being unitary with the remainder of the blanket and having outer portions projecting outwardly from the edges where the handles are located, the handles do not interfere with rolling of the blanket, as for storage of the blanket in a canister. If equipped with the blanket, a worker can manipulate the blanket easily, via the handles, even while the worker is working on a pole, on a ladder, or in an elevated bucket. A group of such blankets, if stacked so that their handles have aligned openings, can be easily manipulated by a worker or workers.
