11. Device Requirements • Use only lockout/tagout devices that have been approved by FM. • Locks/tags must clearly identify the employees who applied them. Note: Key differently. Facilities Management UW-Eau Claire

12. Shutdown Procedures • Prepare for Shutdown • Identify lockout points • Locate and identify all energy isolating devices that apply to the machine/equipment to be locked out. • Refer to the manufacturer’s control diagram detailing the location of all isolating points for complex equipment. • Determine the magnitude of the energy, the hazards of the energy to be controlled, and the methods to control the energy. • If authorized employees are unable to determine each form of energy, they must consult their supervisors before starting work. Facilities Management UW-Eau Claire

13. Shutdown Procedures Cont. • Notification • Notify all affected employees that a lockout/tagout is about to take place. • The reason for the lockout/tagout. • The specific machinery or equipment affected. • Shutdown • Shut Off Equipment • If the equipment is operating, employees shall shut it down by the normal stopping procedures (depress the stop button, open the switch, close valve, etc.) Facilities Management UW-Eau Claire

14. Shutdown Procedures Cont. • Deactivate Energy • Disconnect the device from ALL energy sources • Inspect the equipment to ensure ALL energy sources are disconnected. • Release of Stored or Residual Energy • Release the stored or residual energy such as that in capacitors, springs, elevated machine members, rotating flywheels, hydraulic systems and pressurized systems such as air, gas, steam, or water. Facilities Management UW-Eau Claire

15. Shutdown Procedures Cont. • Attach Locking and Tagging Devices • Locks and tags should be standardized. • Locks shall be attached to energy isolating devices so that they cannot be accidentally detached during maintenance. • Tags shall be attached to all points where equipment or circuits can be energized. • A multiple lock plate shall be used when more than one employees attach their own lock on the same equipment. Facilities Management UW-Eau Claire

16. Shutdown Procedures Cont. • Tryout • Test the deactivation of the equipment to ensure that equipment cannot be energized. • Checking that no personnel are exposed. • Verifying the isolation of equipment by operating the push button or other normal operating controls. • Checking pressure gauges to ensure de-pressurization of lines. • Inspecting electrical circuits to confirm zero voltage. • Testing equipment by pushing start buttons or other controls to make certain the equipment will not run. • Returning the operating control(s) to “NEUTRAL” or “OFF” position after the test. • Ensuring equipment is now locked out/tagged out. Note:If equipment DOES energize on tryout, push the stop button & contact immediate supervisor immediately for further instruction. Facilities Management UW-Eau Claire

17. Outside Personnel (Contractors) • The following procedures should be followed if work activities are performed by contractors: • FM supervisor and contractor shall inform each other of their respective lockout/tagout procedures. • FM supervisor shall ensure that his/her employees understand and comply with the restrictions and prohibitions of the outside employer’s energy control program. • Contractors failing to adhere to lockout/tagout procedures acceptable to FM will be asked to terminate their work until they employ acceptable energy control procedures. Facilities Management UW-Eau Claire

18. Equipment Return to Service • Inspect the machine and work area to ensure that: • Non-essential materials have been removed. • Tools and equipment are removed. • Blocks, pins and chain (used during the lockout) are removed. • Secured safe guards are in place. • All equipment components are fully assembled and operational. • Ensure that all employees have left the area or are safely positioned.

22. Specific Energy Control Procedures • A written procedure is required for piece of equipment or machinery that utilizes multiple power sources. Each case must outline: • ALLenergy sources & lockout points for the equipment or process. • Specific steps to shut down, isolate, block and secure the machine or equipment to control the hazardous energy. • Steps for the placement, removal and transfer of the lockout devices and the responsibility for the devices. • Specific requirements for testing the equipment or machine to ensure the effectiveness of the lockout devices and other energy control devices. Facilities Management UW-Eau Claire

23. Specific Energy Procedures Cont. • Exceptions to Requirement for Specific Energy Control Procedures. • Specific documentation if not required for equipment when all of the following element exist: • Machine/equipment has no potential for stored energy after shut down which could endanger employees. • Machine/equipment has a single energy source that can be readily identified and isolated. • Isolation/locking out of that energy and source will completely de-energize de-active the machine or equipment. • Machine/equipment is isolated from that energy source during servicing or maintenance. • Single lockout device will achieve a locked out condition. Facilities Management UW-Eau Claire

24. Summary • Only authorized personnel may perform lockout/tagout using only the prescribed procedures. • Identify ALL energy sources and establish a zero energy prior to servicing equipment. • Take your time and do it RIGHT!!! (Lockout, Tagout, Tryout) • IF YOU DO NOT KNOW, ASK!!! Facilities Management UW-Eau Claire
