									Control of Hazardous Energy – Lockout/Tagout
              29 CFR 1910.147
          Compliance Training Presentation
   NPCA Safety, Health and Environmental Committee
• As a committee of a national organization, the
  Safety, Health & Environmental Committee of
  NPCA must reference federal standards.
  However, users of this information are informed
  that state and local agencies may have more
  stringent standards than those cited here. It is
  the users responsibility to ensure that the federal
  standards referenced herein are applicable in
  their locale. If more stringent standards apply
  locally, you must adhere to those local
• The purpose of this standard is to
  establish requirements and procedures to
  prevent the unintended release of energy.
• This applies to electrical energy, potential
  energy, gravity, hydraulics, pneumatics,
• When present this energy could cause a
  circuit to energize, or a machine / machine
  part to move or fall, causing injury to an
• Affected Employee – an employee whose job requires
  him/her to operate equipment or work in an area where
  lockout / tagout is performed.
• Authorized Employee – A person who services or
  performs maintenance on equipment that requires
  lockout / tagout.
• Energy Isolation Device – A mechanical device that
  physically prevents the transmission or release of
Definitions (cont)
• Lockout – The placement of a device, such as a keyed
  lock, or other energy isolation device to prevent the
  operation of the equipment until the device is removed.
• Lockout Device – a device that utilizes a positive
  means such as a lock to hold an energy isolating device
  in the safe position and prevent the energizing of the
  machine or equipment.
• Servicing and/or Maintenance – Workplace activities
  where the employee may be exposed to the unexpected
  energizing or startup of the equipment or released
  hazardous energy.
• Tagout – The placement of a tag, in conjunction with a
  lockout device, to indicate the owner of the lockout
• Tagout Device – A prominent warning device, such as a
  tag and a means of attachment, which can be securely
  fastened to the energy isolating device, to indicate that
  the equipment may not be operated until the device is
• Minor tool changes and adjustments, or;
• Servicing or maintenance of equipment
  during normal production if:
   – The safeguards are effective in
     preventing worker exposure to hazards
     that could be created.
• Work on cord and plug connected
  electrical equipment if the equipment is
  unplugged and the authorized employee is
  in control of the plug.
General Requirements
Locks and Tags:
• Make locks and tags available to all
  authorized employees
• Each authorized employee must use his
  or her own lock/tag. They are to keep the
  key with them while performing the work
• Each lock must have only one key. Locks
  with a master key are not permitted.
• Only the authorized user removes the
  lock they installed.
General Requirements
Written Procedures
• The energy control procedures contain
  the instructions for the means to control
  the hazardous energy.
• Specific steps should be included.
• Pictures of disconnect equipment or shut
  off devices are helpful.
• Explain how to test the machine to
  determine if the lockout is effective in
  controlling the hazard.
General Requirements
• Procedures are not required when all of
  the following exist:
  – The machine has no stored or residual energy
  – The machine has a single energy source
  – The lockout of the single source will
    completely de-energize the equipment
  – The machine is isolated and locked out from
    that source during serving or maintenance
General Requirements
• Procedures are not required when all of
  the following exist (continued):
  – The lock out device is under the exclusive
    control of the authorized user
  – No other hazards for employees are created
  – No accidents involving the release of
    hazardous energy have occurred on this
    machine or equipment
Generic Procedure for LOTO
• Only authorized employees
  perform LOTO
• All affected employees are
  notified of LOTO
• Identify the powers source(s)
  for the equipment
• Perform normal shutdown on
  the equipment
• De-energize the power source
Generic Procedure for LOTO
       • Place lockout and tagout
         devices on the power source
       • Test the equipment for potential
       • Return all controls to the neutral
         of off position
       • Maintenance or servicing can
         now be performed
Removal of LOTO

• Make sure all tools are stored
• Verify that the switches are in the neutral
  or off position
• All guards must be in place
Removal of LOTO
• Personnel must be clear of the equipment
• Each authorized person shall remove only
  his or her own lockout and/or tagout
• Return to energy isolating device to its on
Additional Instructions
• When the authorized employee is not available,
  the following actions may be taken:
  – Make a reasonable attempt to contact the authorized
  – Remove all tools and material from the equipment
  – Make sure all affected employees are clear of the
Additional Instructions
• When the authorized employee is not available,
  the following actions may be taken: (cont)
  – With the approval of the Plant Manager, the lock
    and/or tag can be removed.
  – Upon the return of the authorized employee,
    immediately notify them of the removal of their lockout
• Authorized Employees:
  – Instructed in the recognition of applicable
    hazardous energy sources.
  – Instructed in the procedures for lockout /
  – Instructed in the proper procedures for de-
    energizing an energy control device.
  – Instructed in the use of the locks and tags.
  – Instructed in the procedures for restoring
• Affected Employees
  – Instructed in the purpose of lockout / tagout
  – Instructed to refrain from attempting to start or
    re-energize any machine or equipment that is
    locked out or tagged out
• Other Employees
  – All employees will be instructed to stay clear

• Authorized and Affected Employees need to be
  retrained when:

  – there is a change in machines, equipment, or
    processes that present a new hazard
  – there is a change in the energy control procedures
  – periodic inspections reveal that there are deviations in
    the energy control procedures
  – the employer believes that there are deviations from,
    or inadequacies in, the employee’s knowledge or use
    of the energy control procedures
• The objective of retraining is:
  – to introduce new or revised control methods
    and procedures as necessary, and

• Initial training and retraining needs to be
  certified by the employer
• The certification needs to contain the
  instructor, date of training, and content of
  the training, as well as the employees name
Monitoring and Enforcement
• The use of the energy control procedures
  must be periodically monitored.

• Disciplinary action may lead to employee’s
  termination of employment.
Failing to enforce
these procedures
could lead to
Annual Review and Inspection
• The hazardous control policy must be reviewed
  annually. This review will include:
  – an inspection of the written procedures;
  – a review that the procedures are being followed.
• The Plant Manager and Safety Department will
  ensure that this review and inspection is
• A lockout / tagout inspection checklist will be
  used to document this inspection
• Procedures will be updated as necessary
• Employees re-trained as necessary
Annual Review and Inspection
• The annual review and inspection will be
  documented. The following shall be recorded:
  –   The date of the review
  –   The procedure(s) or equipment being reviewed
