The procedures should identify: The person(s) responsible for performing the lockout (for example, operator, millwright, electrician) The person responsible for ensuring that the lockout is properly performed (for example, maintenance supervisor and/or site supervisor) The energy sources to be controlled by the lockout The location of isolation points (example, control panels, valves, blocking points, relief valves and/ or blanking and bleeding points). A review of up-to-date schematics may be required to confirm the location of these devices Special considerations (for example, a flywheel that coasts for several minutes after power is removed or an electrical charge stored at capacitors) The personal protective equipment that must be used or worn (for example, eye protection, electrically insulated foot protection) The work order, if any, for the application of energy control devices The testing procedure to ensure that all energy sources are controlled (including possible stored energy) The step-by-step procedure for removing the lockout once work is complete Electrical Energy Lockout Example Review lockout placard for the equipment. Ensure all shutdown steps and means to control hazardous energy are understood. Advise other people in the area that the equipment will be shut down and locked out Shut down the machine using normal operational shutdown procedure and controls. This should be done by, or in consultation with, the machine operator Move the electrical isolation device to the 'off ' position Caution: Equipment should be properly installed and maintained. If you become aware of strange sounds or smells at or near electrical equipment, immediately contact your supervisor or licensed electrician. Using your own personal lock, or one assigned by your supervisor, lock the electrical isolation device in the off position. Remove the key from your lock and maintain control of the key. Complete a lockout tag and attach to your lock. Each person working on the equipment must lock it out. The lock of the person in charge of the work should be installed first, remain in place throughout the task and be the last lock to be removed WSPS.CA
