Abstract
A plate pivotally mounted to a padlock hasp adjacent a reciprocally movable operator handle is pivotable from a stored position to one covering the opening of the hasp, the plate having a hole aligned with the opening and smaller than the opening to receive the shackle of a single, scissors-type safety lockout and maintain the shackle in position to block movement of the operator handle to an operated position. The hole is preferably rectangular to conform to the flat, thin shape of the safety lockout shackle to maintain the shackle properly oriented. An additional round hole for a smaller diameter padlock shackle may be provided in said plate.
