A lockout for a valve is disclosed. The lockout is adapted to prevent access to, or actuation of, an operational part of the valve. The lockout comprises a valve shell to slide over and at least encircle part of the valve, to prevent withdrawal of the valve shell when under-engaged, a valve saddle to slide over and at least encircle part of the valve, such that the valve saddle is prevented from rotation relative to the valve when straddling, and a locking means to lock the valve shell to the valve saddle. When the valve shell is under-engaged, and the valve saddle is straddling and locked to the valve shell, the operational part of the valve is covered or prevented from being operated by the valve lockout, and the valve lockout is unable to be removed from the valve. |
