Abstract: A valve lock for securing the handle of a pipe. The valve lock includes a first housing having first and second contact points for engaging the pipe and a retention chamber that receives the handle. The first housing is in a final position to prevent rotation of the handle when the retention chamber receives the handle and the first and second contact points are seated against the pipe. A second housing has a third contact point for engaging the pipe and a lock member for disposition relative to the first housing when the first housing is in the final position and the third contact point is seated against the pipe. The lock member receives the shackle of a padlock to secure the lock member to the first housing.

Abstract: A switch lockout device for securing a toggle switch of a circuit breaker. The lockout device includes a housing having an opening for positioning around the toggle switch. A screw is threaded through the housing and is tightened against the toggle switch to restrain it. A circular disk is secured at one end of the screw and is lockable to a member slidable with respect to the housing, for preventing the disk from movement.

Abstract: Switch lockouts are disclosed which may be fixed to a single toggle switch, a ganged toggle switch, or a similarly acting switch, valve operator, or similar structure to prevent the switch from being operated. The lockout comprises a projection and abutments which engage the switch handle and the body of the switch. The projection extends into an aperture of the handle in one embodiment, or under the crossbar of a ganged handle in another. The abutments, and in some instances the projection, embrace the handle and prevent substantial rotation of the handle with respect to the lockout, or of the lockout with respect to the switch body. Thus, the switch handle, switch body, and lockout are fixed substantially immovably together.

Abstract: A lockout device for an electrical switch has a mounting plate adapted to be attached to the cover plate of the electrical switch. The mounting plate has a pair of mounting apertures which permit it to be attached to the face plate and an aperture formed to circumscribe the switch's actuation member. A blocking plate extends from the mounting plate near its bottom edge. A cover is slidably connected to the mounting plate for movement between an open position at which the actuation member is accessible and a closed position at which the open bottom of the cover abuts the blocking plate so that cover and blocking plate enclose the actuation member. A locking mechanism allows the cover to be locked in its closed position. The cover can be transparent so that the actuation member is visible through the cover when the cover is in its closed position.
