Abstract:
1. A lockout device comprising: a first member including a first lockout feature and a first set of apertures; and a second member including a second lockout feature and a second set of apertures, the second member being slideable with respect to the first member and restricted to a range of positions between a first limit position and a second limit position, the range of positions including a lockout position in which the first and second lockout features are positioned to interlock with an external structure, and a release position in which the first and second lockout features are positioned to disengage from the external structure; wherein when the second member is in the lockout position, each of the first set of apertures substantially aligns with a corresponding one of the second set of apertures to define a set of passages for receiving a lock member having a cross-section corresponding to the aligned apertures to secure the second member in the lockout position; and further wherein when the second member is moved out of the lockout position to any other position in the range of positions, the first member at least partially blocks each of the second set of apertures and the second member at least partially blocks each of the first set of apertures, such that the lock member cannot be assembled with the lockout device to secure the second member in any position other than the lockout position.
