Lockout device

A lockout device comprising:

• a first plate including a first lockout feature and at least a first aperture;
• and
• a second plate including a second lockout feature and at least a second aperture, the second plate including a projection disposed within a longitudinal slot in the first plate and slideable between first and second ends of the slot to define a range of positions between first and second limit positions of the second plate with respect to the first plate, wherein the projection includes an enlarged end portion extending laterally outward of the longitudinal slot and sized to prevent withdrawal of the projection from the slot, thereby securing the second plate against separation from the first plate;
• wherein the range of positions includes a first lockout position in which the first and second lockout features are positioned to interlock with a first external structure, and a release position in which the first and second lockout features are positioned to disengage from the first external structure;
• and
• further wherein when the second plate is in the first lockout position, the first aperture substantially aligns with the second aperture to define a first passage for receiving a lock member having a cross-section corresponding to the aligned first and second apertures to secure the second plate in the first lockout position.

A lockout device comprising:

• a first member including a first lockout feature and first and second apertures;
• and
• a second member including a second lockout feature and third and fourth apertures, the second member being assembled with the first member and slideable in an axial direction with respect to the first member and restricted to a range of sliding positions between a first limit position and a second limit position, wherein the range of positions includes a first lockout position in which the first and second lockout features are positioned to interlock with a first external structure, and a second lockout position, different from the first lockout position, in which the first and second lockout features are positioned to interlock with a second external structure dimensionally different from the first external structure;
• wherein when the second member is in the first lockout position, the first aperture substantially aligns with the third aperture to define a first passage for receiving a lock member having a cross-section corresponding to the aligned first and third apertures to secure the second member in the first lockout position;
• and
• wherein when the second member is in the second lockout position, the fourth aperture substantially aligns with the second aperture to define a second passage for receiving the lock member to secure the second member in the second lockout position.
