This included all stored energy (mechanical, hydraulic, air, etc.). After the lockout, the Project Engineer shall verify that the system(s) are de-energized by operating the switch or device that normally activates the equipment.</p><p> In the event that equipment or lines cannot be shut down, locked-out and tagged, a safe job procedure shall be established and rigidly followed.</p><p>The Project Engineer is the authorized employee responsible for the isolation of all potential energy sources. The Electrical Services Craftsperson shall verify the correct lockout –tag out procedure with the Project Engineer.</p><p>This method of lockout tagout for this project shall be communicated to all shutdown personnel. </p><p>Before the Project Engineer and the Electrical Services Craftsperson turns off and attaches a lock and tag to machinery, equipment and breakers, the Project Engineer shall have knowledge of the type and magnitude of the energy, the hazards of the energy to be controlled, and the method or means to control the energy.</p><p>The Project Engineer and the Risk Management Specialist (or the person designated as the project safety adviser) shall have keys for the locks. No one, including the Risk Management Specialist (less the removal exeception noted below) shall remove a lock, without written permission from the Project Engineer.</p><p>Locks with tags (signed by the Project Engineer) shall be affixed to each energy isolating device by the Project Engineer with the advisement of the Electrical Services Craftsperson. Locks with tags, where used, shall be affixed in a manner to that will hold the energy isolating devices in a "safe" or "off" position.</p><p>The following devices are to be secured and/or locked out for the removal of the Primary Mirror, the F8 Mirror or during telescope maintenance:</p><p> Install stay bars from the horseshoe to the tube assembly</p><p> Install slings to the trusses to enable the use of personal protective equipment (retractors).</p><p> Place “do not operate” sign on console in control room</p><p> Remove and secure telescope “main power key” in the control room, Project Engineer responsiblity</p><p>SCREEN ROOM LOCKOUT – TAGOUT:  Panel 3S, Switch A2  Panel 3S, Switch A5  Panel 3R, Switch A4  Panel 3S, Switch A3  Panel 3S, Switch A6  Panel 3R, Switch A6  Panel 3S, Switch A4  Panel 3S, Switch A7  Panel 3R, Switch A7  Panel 3K, Switch A5  Panel 3P, Switch A6  Panel 3M, Switch A2  Panel 3P, Switch A7  Panel 3M, Switch A3  Panel 3J, Switch A4  Panel 3M, Switch A6  Panel 3N, Switch A4  Panel 3H, Switch A4-B7  Panel 3N, Switch A5  Panel 3K, Switch A2  Panel 3H, Switch A4-B9  Panel 3N, Switch A6  Panel 3K, Switch A3 </p><p>PUMP ROOM LOCKOUT – TAGOUT:</p><p> Oil Pump #1, PL.P2-8  Oil Pump Room #2, 480vac, PL.P2-8</p><p>MEZZANINE FLOOR BEHIND THE SOUTH JOURNAL:</p><p> 25 UPS AND RUPS to Cage  26 UPS and RUPS to Cage</p><p>Before starting shutdown work and after equipment has been locked and tagged, the Project Engineer shall verify that isolation and de-energization has been accomplished.</p><p>The Risk Management Specialist (or the person designated as the project safety advisor) shall perform periodic inspections of the energy control procedure.</p><p>Release from lockout tagout Before lockout tagout devices are removed and energy is restored, the following procedures and actions taken by the Project Engineer shall be followed:</p><p> The work area shall be inspected to ensure that nonessential items have been removed and equipment components are operationally intact.</p><p> Verification by personal account that all employees are clear from the site</p><p> The Project Engineer with the advisement of the Electrical Services Craftsperson shall remove each lockout tagout device from each energy-isolating device.</p><p>Removal Exception: When the Project Engineer is not available to remove lockout tagout devices the Risk Management Specialist may remove the lockout tagout devices if there is:  Verification that the Project Engineer who applied the device is not at the facility  Making all reasonable efforts to contact the Project Engineer to inform him/her that his/her lockout tagout device has been removed  Ensuring that the Project Engineer has this knowledge before he/she resumes work at that facility  After lockout tagout devices have been removed and before equipment is started, employees shall be notified that the lockout or tagout device(s) have been removed.</p>
