Facilities Management UW-Eau Claire
Definitions• Lockout
– The placement of a lockout device in accordance with established procedures, ensuring that the energy-isolating device and the equipment being controlled may not be operated until the lockout is removed.
• Tagout– The placement of a tagout device in
accordance with an established procedure to indicate that the energy-isolating device and the equipment being controlled may not be operated until the tagout is removed.
Note: FM uses both lockout/tagout devices.

Facilities Management UW-Eau Claire
General Procedures• Electrical Procedures
– Shut off power on machine and disconnect.– Lockout/tagout on disconnect sources.– Press start button to ensure that energy
source has been locked.– Remember the keys points:
• If a machine or piece of equipment contains capacitors, they must be drained of stored energy.
• Possible disconnecting sources include the power cord, power panels (look for primary & secondary voltage), breakers, the operator’s station, motor circuit, relays, limit switches, electrical interlocks.
Facilities Management UW-Eau Claire

General Procedures Cont.
• Fluids and Gases– Identify the type of fluid or gas properly.– Close valves to prevent flow during
lockout/tagout.– Determine the isolating device, close and
lockout/tagout.– Drain and bleed lines to zero energy state.– Check for zero energy state on the
equipment.
Facilities Management UW-Eau Claire
General Procedures Cont.• Mechanical Energy Procedures
– Block out or use die ram safety chain.– Lockout or tagout safety device.– Shut off, lockout or tagout electrical system.– Check for zero energy state on equipment.– Return controls to safest position.
• Extra precaution– Know equipment and systems
• Understand equipment hazards• Isolation points• Procedures for lockout
Facilities Management UW-Eau Claire
Device Requirements• Use only lockout/tagout devices that
have been approved by FP&M.• Locks/tags must clearly identify the
employees who applied them.
Note: Key differently.
Facilities Management UW-Eau Claire
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
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
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
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
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
Group Lockout/Tagout Procedures• The primary authorized employee applies a multi-lock
accepting device to the energy – isolating device and attaches his/her lock.
• One authorized employee in the group is allowed to function as the lockout/tagout coordinator to ensure that all control methods are applied and there is continuity of protection for the group.
• Each authorized employee shall affix a personal lockout/tagout device to the multi-lock accepting device when they begin work and shall remove those devices when they stop work.
• The primary authorized employee removes his/her lock and the multi-lock accepting device when all work has been completed.

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.
