A lockout system includes a hasp assembly and a plurality of tags. The hasp assembly has a back plate defining slots each sized and shaped to receive a tag. The back plate and tags each have openings that align when a tag is received in a slot. A first hasp portion on the back plate defines part of a closed loop. A longitudinal locking bar is slidable along the back plate and has notches shaped to receive ends of the tags. Moving the locking bar between an unlocked position and a locked position operates the second hasp portion between an open position and a closed position. In the closed position, the first and second hasp portions complete and define the closed loop, where one or more tags can be installed in slots with the first end of the tag engaging a notch to lock closed the hasp portion.

A security device for securing a key by using multiple locks consists of a first rotational member, a second rotational member, a pivoting mechanism, a first plurality of lock-receiving holes, and a second plurality of lock-receiving holes. The key that needs to be secured is enclosed by the first rotational member and the second rotational member that are connected to each other through the pivoting mechanism. The pivoting mechanism allows the key to be either exposed or concealed upon user preference. The first plurality of lock-receiving holes and the second plurality of lock-receiving holes are designed and positioned to receive a shackle from at least one lock so that the key is securely enclosed by the first rotational member and the second rotational member.
