3. Keys will be removed from the padlock at the time of the lockout.
4. Before repair work is started, equipment will be tested to ensure power is off.
5. Before starting repairs, the person performing the work shall make sure that any hazardous residual gravity pressure is relived.
6. Any equipment that needs blocking to prevent its movement by gravity or other means must be blocked.
7. A machine connected to an electrical source by a plug-in cord shall be disconnected and the plug secured in a lockout box. (plugs are acceptable as disconnecting means only for portable motors and 110v fixed equipment).
