A lockout device includes an inner housing and an outer housing. The inner housing has an upper end portion, a lower end portion, an arcuate outer portion extending between the upper and lower end portions, and a central bearing portion extending outward from at least one of the upper and lower end portions. The outer housing has an upper end portion, a lower end portion, an arcuate outer portion extending between the upper and lower end portions, and a central opening disposed on at least one of the upper and lower end portions and sized to receive and bear against the central bearing portion of the inner housing for telescopic rotation of the inner housing with respect to the outer housing. The outer housing is sized to at least partially receive the inner housing when the inner and outer housing are rotated to an open position.

What is claimed is: 1. A lockout device comprising: an inner housing having an upper end portion, a lower end portion, an arcuate outer portion extending between the upper and lower end portions, a first central bearing portion extending outward from the upper end portion, and a second central bearing portion extending outward from the lower end portion, the second central bearing portion at least partially surrounding a central opening in the lower end portion; and an outer housing having an upper end portion, a lower end portion, an arcuate outer portion extending between the upper and lower end portions, a first central opening disposed on the upper end portion and sized to receive and bear against the first central bearing portion of the inner housing, and a second central opening disposed on the lower end portion and sized to receive and bear against the second central bearing portion of the inner housing; wherein the inner housing further comprises one of an arcuate rail and an arcuate track extending from an outer surface of the arcuate outer portion between the first and second central bearing portions, and the outer housing further comprises the other of the arcuate rail and arcuate track extending from an inner surface of the arcuate outer portion between the first and second central openings, further wherein the rail slides along the track to provide telescopic and rotational movement of the inner housing with respect to the outer housing. 2. The lockout device of claim 1, wherein each of the inner and outer housings comprises a lock tab extending from the outer portion, wherein at least one opening in the inner housing lock tab aligns with at least one opening in the outer housing lock tab when the inner and outer housings are in a closed position, to allow insertion of a locking member therethrough. 3. The lockout device of claim 1, wherein the engagement of a central bearing portion with the central opening centers the inner housing within the outer housing to prevent contact between the outer portion of the inner housing and the outer portion of the outer housing when the inner and outer housings are rotated between closed and open positions. 4. The lockout device of claim 1, wherein the outer housing comprises upper and lower housing members configured to assemble with each other and around the inner housing. 5. The lockout device of claim 4, wherein one of the upper and lower housing members comprises at least one projection and the other of the upper and lower housing members comprises at least one opening for receiving the projection for assembly of the upper and lower housing members. 6. The lockout device of claim 5, wherein the at least one projection and the at least one opening are configured for locking snap-fit engagement. 7. The lockout device of claim 1, wherein an internal surface of one of the upper and lower end portions of the outer housing comprises at least one ridge configured to reduce contacting surfaces between the outer housing and the inner housing. 8. The lockout device of claim 1, wherein the central opening of a outer housing is defined by a circular ring. 9. The lockout device of claim 1, wherein the central opening of the outer housing is defined by an arcuate edge having a circumference greater than 180 degrees. 10. The lockout device of claim 1, wherein the inner housing comprises an arcuate outer rail extending along the outer portion of the inner housing, and the outer housing comprises an arcuate inner track extending along the outer portion of the outer housing for receiving the rail therein. 11. The lockout device of claim 1, further comprising a central covering portion separably connected with the device to cover a central opening. 12. A portable lockout device for preventing use of a handle or the like, comprising: an inner piece and an outer piece, each of the inner piece and the outer piece having an arcuate outer surface and an arcuate inner surface, wherein said inner piece and said outer piece are telescopically and rotationally engaged such that said inner piece is substantially nested within said outer piece when said lockout device is in an opened position and substantially extended from within said outer piece when said lockout device is in a closed position; an arcuate rail projecting from the outer surface of said inner piece; an arcuate track disposed on the inner surface of said outer piece, wherein said rail slides along said track to provide telescopic and rotational movement of said inner and outer pieces, wherein the inner piece further comprises a first lock tab disposed on the rail, further wherein at least one opening in the first lock tab aligns with a corresponding opening in a second lock tab disposed on an outer surface of the outer piece, to allow insertion of a locking member therethrough. 13. The lockout device of claim 12, wherein the inner piece and outer piece comprise bearing surfaces spaced apart from the rail and track and configured to contact each other during rotational movement of said inner and outer pieces. 14. The lockout device of claim 13, wherein the bearing surfaces of the inner and outer pieces are disposed at a central portion of the inner and outer pieces. 15. The lockout device of claim 13, wherein the bearing surface of the outer piece is disposed on a central opening and the bearing surface of the inner piece is disposed on a central wall extending axially through the central opening. 16. The lockout device of claim 15, wherein the central opening is defined by an arcuate edge. 17. The lockout device of claim 16, wherein the arcuate edge has a circumference greater than 180 degrees. 18. The lockout device of claim 16, wherein the central opening is defined by a circular ring. 19. The lockout device of claim 15, further comprising a central covering portion separably connected with the device to cover the central opening, to restrict access to a handle when the lockout device is in the closed position over the handle. 20. The lockout device of claim 12, wherein the outer piece further comprises a portion disposed at an end of the track for receiving the first lock tab when the lockout device is in the closed position. 21. A portable lockout device for preventing use of a handle or the like, comprising: an inner piece and an outer piece, each of the inner piece and the outer piece having an arcuate outer surface and an arcuate inner surface, wherein said inner piece and said outer piece are telescopically and rotationally engaged such that said inner piece is substantially nested within said outer piece when said lockout device is in an opened position and substantially extended from within said outer piece when said lockout device is in a closed position; an arcuate rail projecting from the outer surface of said inner piece; an arcuate track disposed on the inner surface of said outer piece, wherein said rail slides along said track to provide telescopic and rotational movement of said inner and outer pieces, wherein the outer piece is formed from an upper member defining a first side of the track and a lower member defining a second side of the track, the upper and lower members being joined together to capture the rail between the first and second sides of the track.
