Why is Lock Out/Tag Out Why is Lock Out/Tag Out Procedure Important?Procedure Important?
• Prevents the unexpected machine start-up or release of stored energy.
• Use of lock/block out devices or tags… • Protects from employees injury & death.
Some DefinitionsSome Definitions
• Affected employee– Person operating working in area where work
is performed under lockout tagout.• Authorized employee
– Employee who locks out or tags out machine to perform maintenance, cleaning or adjustment.
• Locked out– Devices, methods, or procedures that isolate prime
movers and/or any hazardous energy sources
More DefinitionsMore Definitions
• Prime mover– Source of mechanical power for a machine
• Tag out– Card or tag used to identify a hazard
• Block– Device to prevent inadvertent falling, movement or
rotation.
• Blind– Metal disc placed in pipe to insure no flow of gas,
steam or liquid
Hazardous Energy SourcesHazardous Energy Sources
• Electrical• Mechanical (i.e.
motors, drive belts)• Chemical (i.e. natural
gas, propane)• Thermal• Pneumatic• Hydraulic
Equipment SurveyEquipment Survey
• Locate and identify sources of energy
• Identify energy type and magnitude
• Done through visual inspections, drawings and equipment manuals
Equipment SpecificEquipment Specific Lock Out/Tag Out Lock Out/Tag Out
• Equipment Specific Lock Out/Tag Out procedures for each machine must be completed by the supervisor and/or the authorized employee.
• All equipment specific procedures must be easily accessible or posted directly on the equipment.
Lock Out/Tag Out ProgramLock Out/Tag Out ProgramEquipment Specific ProceduresEquipment Specific Procedures
Procedures must be updated when:
• New equipment is installed; or
• New energy sources are added to a facility or individual equipment; or
• Magnitude of an energy source changes; or
• Designated isolation points change.

• Lock out
• Lock and key.
• Chains, or other hardware,
• Used with the lock to isolate the energy source.
Lock Out/Tag Out ProgramLock Out/Tag Out ProgramEquipmentEquipment
• One key will be issued to the authorized employee applying the lock.
• Additional keys will only be used to remove locks in the event the abandoned lock procedure must be implemented.
Lock Out/Tag Out Lock Out/Tag Out Program ProgramEquipmentEquipment
• Locks & Devices used only for controlling energy
• Must NOT be used for any other purposes.
Lock Out/Tag Out ProgramLock Out/Tag Out ProgramEquipmentEquipment
• Lock Out devices must be durable• Tag Out devices must be constructed & printed
so they do not deteriorate or become illegible;• Lock Out/Tag Out devices must be standardized
by color, shape or size;• Lock Out/Tag Out devices must be substantial
enough to prevent early or accidental removal.
Lock Out/Tag Out Lock Out/Tag Out Program ProgramEquipmentEquipment
• Tag Out devices must include a wording such as: DO NOT START, DO NOT OPEN, DO NOT CLOSE, DO NOT ENERGIZE, DO NOT OPERATE, etc.
• Tag Out devices must have standardized print and format.
Lock Out/Tag Out Lock Out/Tag Out Program ProgramEquipmentEquipment
• An approved warning tag will accompany all lockouts.
• The warning tag will be attached directly to the lockout device by a nylon tie.
Required Tag Out Device Required Tag Out Device InformationInformation
• Name of authorized employee who locked out equipment;
• Authorized employee’s radio or phone number, including contractors;
• Date and time of lockout; and
• Brief description of work being performed.
Lock Out/Tag Out ProgramLock Out/Tag Out ProgramApplication of DevicesApplication of Devices
• Use valve covers, plug locks, etc. if the lock can’t be placed directly on the energy control.
• When Lock Out is used, every employee in the work crew must attach their personal lock.
Lock Out/Tag Out ProgramLock Out/Tag Out ProgramProceduresProcedures
• Preparation for shutdown
• Shutting down the equipment
• Equipment isolation
• Application of Lock Out/Tag Out devices
• Release of stored energy
• Verifying equipment isolation
• Restart machine
Lock Out/Tag Out ProgramLock Out/Tag Out ProgramPrep For ShutdownPrep For Shutdown
• Know the types and amounts of energy that power specific equipment.
• Know and understand all energy flow through the machine.
• Know how the energy can be controlled.
• When in doubt ask!
Lock Out/Tag Out ProgramLock Out/Tag Out ProgramShutting Down EquipmentShutting Down Equipment
• Notify ALL affected employees that Lock Out Tag/Out is being used and why.
• Shut the equipment down using operating controls.
• Follow proper procedure for the equipment to avoid endangering anyone during the shutdown.
Lock Out/Tag Out ProgramLock Out/Tag Out ProgramEnergy IsolationEnergy Isolation
• Lock Out & Tag Out energy isolating sources with assigned locks and tags. Usually requires locking out electrical disconnect.
• Be sure to isolate ALL energy sources (secondary as well as primary).
Verifying Equipment IsolationVerifying Equipment Isolation
• Make certain all dangerous areas are clear of personnel.
• Verify that the equipment cannot be turned to the “on” position.
• Press all “start” buttons and activating controls on the equipment.
• Return all controls to the “off” position after certain that Lock Out is effective.
Lock Out/Tag Out ProgramLock Out/Tag Out ProgramRelease of Stored EnergyRelease of Stored Energy
• Inspect the system to make sure all parts have stopped moving.
• Disperse stored energy (springs, hydraulic systems, air, gas, water pressure, or steam).
• If stored energy can build up again, monitor it to make certain it stays below hazardous levels.
Removing Lock Out/Tag Out Devices/Restoring Equipment
• Make certain everyone is clear of the equipment.
• Notify affected employees of restart• Verify that all tools have been removed
and all guards reinstalled.• Remove Lock Out/Tag Out devices. Each
device must be removed by the person who put it on.
• Energize equipment.
Lock Out/Tag Out ProgramTroubleshooting
• Remove all tools & personnel from the area.
• Notify affected employees of impending re-energization.
• Authorized employees remove the Lock Out device but MUST leave tag in place.
• Energize equipment.• When finished, de-energize & reapply

Lock Out/Tag Out ProgramAbandoned Lock Procedure
• Verify authorized employee has left the worksite & notify them that their lock is being removed.
• Lock Out/Tag Out devices may ONLY be removed if supervisor is present & authorizes removal.
• After all communication attempts are complete & the equipment has been inspected, energy can be restored.
ExceptionsExceptions
• Work on cord & plug equipment IF it is unplugged, the plug remains within arms reach during servicing and authorized employee has exclusive control of the plug.
• If guards aren’t removed or bypassed & are effective in preventing worker exposure to hazards created by the unexpected energization or start up of machines or equipment, or the release of energy.
