An apparatus includes a cylindrical body that is formed from soft and resilient material and has a smooth outer surface provided with surface indicia coated thereon that has a fluorescent color for drawing attention thereto. The body further has a bore formed therein that extends through the length thereof and has an open and a closed end portion. An aperture is formed in the body that penetrates the body and terminates laterally of the bore. A sleeve formed from rigid material is nested within the bore, confronts an interior surface of the body and spans between the open and closed end portions of the body. A tether is included that has opposed end portions connected to the body and the valve assembly. The tether is attached proximate to one end portion of the body such that the apparatus can be detached while the tether remains engaged with the valve assembly.

1. An apparatus for shielding an operator from an industrial sized valve stem protruding outwardly from a valve assembly, said apparatus comprising:a cylindrical body sized and shaped for fitting about the valve stem, said body being formed from soft and resilient material and having a smooth outer surface extending about a longitudinal length of the valve stem, said outer surface being provided with surface indicia coated thereon wherein the surface indicia has a fluorescent color for drawing attention towards the valve stem, said body further having a centrally disposed longitudinal axis passing therethrough and a bore axially formed therein wherein the bore uniformly extends through the longitudinal length of said body, said body further having an open end portion and a closed end portion oppositely spaced therefrom in such a manner that said body can be slidably positioned about the valve stem without damaging said body, said body further having an aperture formed therein and situated transverse to the bore wherein the aperture penetrates said body and terminates laterally of the bore;a sleeve formed from rigid and non-corrosive material nested within the bore, said sleeve confronting an interior surface of said body and maintaining continuous surface area contact therewith such that the valve stem can not penetrate or pierce through said body during repeated use, said sleeve spanning between said open and closed end portions of said body and maintaining the valve stem spaced from said body; anda tether having opposed end portions directly connected to said body and removably attached directly to a selected portion of the valve assembly such that said body can not be separated beyond a predetermined distance from the valve stem.2. The apparatus of claim 1, wherein said sleeve is formed from plastic.3. The apparatus of claim 2, wherein said sleeve has a cylindrical shape and an annular cross-section.4. The apparatus of claim 3, wherein said tether comprises: a fastening member attached to one said end portions thereof for assisting an operator to quickly disconnect said apparatus from the valve assembly.5. The apparatus of claim 4, wherein said body is formed from non-corrosive material.6. An apparatus for shielding an operator from an industrial sized valve stem protruding outwardly from a valve assembly, said apparatus comprising:a cylindrical body sized and shaped for fitting about the valve stem, said body being formed from soft and resilient material and having a smooth outer surface extending about a longitudinal length of the valve stem, said outer surface being provided with surface indicia coated thereon wherein the surface indicia has a fluorescent color for drawing attention towards the valve stem, said body further having a centrally disposed longitudinal axis passing therethrough and a bore axially formed therein wherein the bore uniformly extends through the longitudinal length of said body, said body further having an open end portion and a closed end portion oppositely spaced therefrom in such a manner that said body can be slidably positioned about the valve stem without damaging said body, said body further having an aperture formed therein and situated transverse to the bore wherein the aperture penetrates said body and terminates laterally of the bore;a sleeve formed from rigid and non-corrosive material nested within the bore, said sleeve confronting an interior surface of said body and maintaining continuous surface area contact therewith such that the valve stem can not penetrate or pierce through said body during repeated use, said sleeve spanning between said open and closed end portions of said body and maintaining the valve stem spaced from said body; anda tether having opposed end portions directly connected to said body and removably attached directly to a selected portion of the valve assembly such that said body can not be separated beyond a predetermined distance from the valve stem;wherein said tether is attached proximate to one said end portions of said body such that said apparatus can be readily detached while said tether remains engaged with the valve assembly.7. The apparatus of claim 6, wherein said sleeve is formed from plastic.8. The apparatus of claim 7, wherein said sleeve has a cylindrical shape and an annular cross-section.9. The apparatus of claim 8, wherein said tether comprises: a fastening member attached to one said end portions thereof for assisting an operator to quickly disconnect said apparatus from the valve assembly.10. The apparatus of claim 9, wherein said body is formed from non-corrosive material.11. An apparatus for shielding an operator from an industrial sized valve stem protruding outwardly from a valve assembly, said apparatus comprising:a cylindrical body sized and shaped for fitting about the valve stem, said body being formed from soft and resilient material and having a smooth outer surface extending about a longitudinal length of the valve stem, said outer surface being provided with surface indicia coated thereon wherein the surface indicia has a fluorescent color for drawing attention towards the valve stem, said body further having a centrally disposed longitudinal axis passing therethrough and a bore axially formed therein wherein the bore uniformly extends through the longitudinal length of said body, said body further having an open end portion and a closed end portion oppositely spaced therefrom in such a manner that said body can be slidably positioned about the valve stem without damaging said body, said body further having an aperture formed therein and situated transverse to the bore wherein the aperture penetrates said body and terminates laterally of the bore;wherein said body has a thickness greater than a thickness of said sleeve;a sleeve formed from rigid and non-corrosive material nested within the bore, said sleeve confronting an interior surface of said body and maintaining continuous surface area contact therewith such that the valve stem can not penetrate or pierce through said body during repeated use, said sleeve spanning between said open and closed end portions of said body and maintaining the valve stem spaced from said body; anda tether having opposed end portions directly connected to said body and removably attached directly to a selected portion of the valve assembly such that said body can not be separated beyond a predetermined distance from the valve stem;wherein said tether is attached proximate to one said end portions of said body such that said apparatus can be readily detached while said tether remains engaged with the valve assembly.12. The apparatus of claim 11, wherein said sleeve is formed from plastic.13. The apparatus of claim 12, wherein said sleeve has a cylindrical shape and an annular cross-section.14. The apparatus of claim 13, wherein said tether comprises: a fastening member attached to one said end portions thereof for assisting an operator to quickly disconnect said apparatus from the valve assembly.15. The apparatus of claim 14, wherein said body is formed from non-corrosive material.
