Abstract

A fitting lockout device includes first and second plate members each having proximal and distal end portions. The first plate member has at least a first cutout disposed between the proximal and distal end portions, and at least a first lock aperture disposed in the distal end portion. The second plate member has at least a second cutout disposed between the proximal and distal end portions, and at least a second lock aperture disposed in the distal end portion. The proximal end portion of the first plate member is pivotally connected to the proximal end portion of the second plate member such that the first and second plate members may be pivoted to align the first and second lock apertures for receipt of a locking member therethrough. When the first and second lock apertures are aligned, the first and second cutouts overlap to define an opening for securely retaining a recessed portion of a fitting.
