3 EQUIPMENT SPECIFIC ENERGY CONTROL PROCEDURAL STEPS: SECTION A. ENERGY CONTROL APPLICATION STEPS: Step 1: All authorized employees performing the servicing or maintenance review and familiarize themselves with the equipments energy types, magnitudes, energy isolating devices and locations and the required energy control devices. The required types and numbers of energy control devices are obtained. A lead authorized employee is selected. The lead authorized employee makes an authorized employee list with the names of each authorized employee assisting with the servicing or maintenance work. Any authorized employee leaving before the work is finished will immediately remove their all locks and/or tags and report to the lead authorized employee to have their name removed from the list. Step 2: All of the affected employees that operate this equipment and/or work in the area around it are notified that it will be shut down and locked and/or tagged out, prior to the application of the energy control devices. The lead authorized employee makes a list of all the affected employees. Any affected employee leaving before the work is finished will immediately report to the lead authorized employee to have their name removed from the list. If a shift change occurs before the job is complete, the names of the affected employees will be checked off and a new list will be created with the affected employees on the next shift. Step 3: Shut down the equipment using the operating controls and the procedures as instructed or provided by the affected employees, or using the manufacturer s written instructions. Step 4: Completely isolate the machine or equipment from its external energy sources by placing the energy isolating devices listed on the Equipment Hazardous Energy Source Control Table in the off or disconnected position. An energy control devices are placed on all energy isolating devices to keep them in that position. Step 5: Each authorized employee places their own lockout or tagout device on each energy control device. Lockout devices are placed to prevent movement from the off position. Tagout devices are placed to indicate movement from the on to the off position, and are placed where locks would be or as close to the energy isolating device as possible. Where tagout is used the additional protective actions described on the Equipment Hazardous Energy Source Control Table are performed to provide full employee protection. 3

4 Step 6: Release or restrain all residual energy, using the methods given on the Equipment Hazardous Energy Source Control Table. Throughout the rest of the procedure perform the residual energy re-accumulation prevention method at the frequency needed to prevent it from accumulating to a hazardous level. Step 7: Re-check that the equipment is disconnected from all energy sources, and all residual energy has been released or controlled. The lead authorized employee removes all authorized and affected employees from the equipment to a safe area confirming their presence with the lists compiled in Step 1 and Step 2. The lead authorized employee with an affected employee qualified to operate the equipment then verify the isolation of the equipment by attempting to start it using the standard operating procedures. Once this test is complete they return the operating controls to the safe, neutral or off position. SECTION B. GROUP ENERGY CONTROL PROCEDURE STEPS: Note: If the number of authorized employees working on the equipment makes the number of locks required to isolate it impractical, take these additional steps and use the group energy control procedure. This is only allowed only for equipment where lockout can be used. Step 1: If multiple groups of authorized employees are working on the equipment a lead authorized employee for each group is selected as outlined in Step 1 of Section A. A lead authorized employee for the job is also selected that places the locks to control the energy to the equipment. All lead authorized employee(s) must be present for the duration of the work or until the end of the work-shift when control of the group lockbox(s) is/are transferred or released. The lead authorized employee for each work group observes the attempt to start the equipment performed in Step 7 of Section A. Step 2: The lead authorized employee for the job places all of the keys from the lockout locks they placed in Step 5 of Section A into a group lockbox, closes the box, places a multi lockout device on the box, and then puts their lock at the top of that multi-lockout device. This is the primary lockbox for the job. Step 3: Each authorized employee applies their lock to the multi lockout device, with additional devices added to provide enough space for each authorized employee to apply their lock to the primary lockbox. 4

5 As they apply their locks each authorized employee puts their name on the list kept by the lead authorized employee for their group. Satellite Lockbox Alternative: If multiple work groups are involved each and each work group has selected a lead authorized employee, that person places their lock on the primary lockbox. They then place all the keys for the lock they placed on the primary lockbox into the satellite lockbox for their group onto which they and all the other authorized employees in their work group places their locks.) Step 4: Authorized employees remove their lock immediately whenever they stop working on the equipment and report to the lead authorized employee to have their name removed from the list. Step 5: At shift change the lead authorized employee(s) has every authorized employee remaining on their list come to the primary or satellite lockbox to remove their locks together leaving only the lead employee s lock. When the lead employee for the next shift is present, the lead employee for the current shift removes their lock, which is immediately replaced by the lock of the lead employee for the next shift at the top of the multi lockout device. Then the rest of their authorized employees apply their locks and add their names to the list for the lead authorized employees for the new shift. The lead employee for the new shift also receives and updated the affected employee list, if applicable. Step 6: At the end or the job, or if the equipment needs to be repositioned or tested, the lead authorized employee(s) has every authorized employee remaining on their list come to the lockbox to remove their locks until only the lead employee s lock remains. The lead authorized employee then positions their authorized employees and any affected employees in a safe area and performs the applicable steps in Section C. At no time do the authorized or affected employees leave the safe area until released by their lead authorized employee. THE MACHINE OR EQUIPMENT IS NOW LOCKED AND/OR TAGGED OUT AND THE SERVICING OR MAINTENANCE WORK CAN BE PERFORMED SAFELY. 5

6 SECTION C. EQUIPMENT RE-POSITIONING OR TESTING/ENERGY CONTROL RELEASE STEPS: Step 1: The authorized employees inspect the equipment to assure all foreign items have been removed and it is in proper operating condition and ready for re-energization. Step 2: All affected employees are removed to a safe location with their presence confirmed using the list made by the lead authorized employee. Step 3: The lead authorized employee with assistance from an affected employee qualified to operate the equipment check to assure that the operating controls are in the safe, neutral or off position and the affected employee returns to the safe area. Step 4: All lockout and/or tagout devices are removed by the authorized employee(s) that placed them. Step 5: All authorized employees are removed to a safe area with their presence confirmed using the list made by the lead authorized employee. Step 6: All energy control devices are removed by the lead authorized employee with the assistance of one other authorized employee, who stays with them and returns to the safe location once they have been removed and the energy isolating devices have been placed back in the energized position. Step 7: The equipment is operated to allow the required testing or repositioning by the lead authorized employee and an affected employee that is qualified to operate the equipment. This step may also be used to remove energy blocking devices, if applicable. Step 8: Repeat the steps in Section A to reapply energy control or notify all the authorized and affected employees involved that the equipment is being released for operation. 6
