ABSTRACT:
A lockout apparatus for use on a valve's latching mechanism. The lockout apparatus is a rigid framework formed to encage the exterior structure of a valve and to provide a locking structural member for selective locked securement of the valve's movable latching mechanism, by example in a closed position. The lockout apparatus is sized according to the diameter and size of a valve, by example a ball valve, and includes opposing open-ended structure for accommodating attachment of piping to the inlet and outlet ends of an encaged valve. The locking apparatus is useful in meeting environmental protection requirements for locking outside valves, typically ball valves, an oil tanks and tanker trailers to avoid vandalism and accidental spills.
