Abstract
A valve lockout device having two pieces. A first piece of the device is a hollow object, substantially tubular or block-shaped, open at a bottom end and having slots open on two sides, that fits over a valve whose handle is to be fixed (or locked). A pocket in the first piece receives the handle and limits the motion of the handle relative to the valve body, thereby preventing operation of the valve. A second piece of the device is a substantially U-shaped object which is pivotally attached to the first piece. When the second piece is rotated to a closed position, it captures the valve handle in the pocket of the first piece, thereby preventing the valve lockout device from being removed. When the second piece is in the closed position, a padlock loop on the first piece extends through a padlock receiving opening in the second piece. Putting a padlock through the padlock loop will prevent the second piece from being rotated out of its closed position, thereby locking the device to the valve.
