• Compliance Training Presentation
• NPCA Safety, Health and Environmental Committee

2
Disclaimer

• 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
  requirements.

3
Purpose

• The purpose of this guide is to establish
  requirements and procedures to prevent the
  unintended release of energy.
• This applies to electrical energy, potential
  energy, gravity, hydraulics, pneumatics, etc.
• When present this energy could cause a circuit to
  energize, or a machine / machine part to move or
  fall, causing injury to an employee.

4
Definitions

• 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 energy.

5
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.

6
Definitions

• 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 device.
• 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 removed.

7
Exemptions

• 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.

8
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.

9
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.

10
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

11
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

12
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

13
Generic Procedure for LOTO

• Place lockout and tagout devices on the power
  source
• Test the equipment for potential energy
• Return all controls to the neutral of off
  position
• Maintenance or servicing can now be performed

14
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

15
Removal of LOTO

• Personnel must be clear of the equipment
• Each authorized person shall remove only his or
  her own lockout and/or tagout device
• Return to energy isolating device to its on
  position

16
Training

• Authorized Employees
• Instructed in the recognition of applicable
  hazardous energy sources.
• Instructed in the procedures for lockout / tagout
• 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 energy.

17
Training

• 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 of
  equipment or machines that are locked out or
  tagged out

18
Training

• Authorized and Affected Employees need to be
  retrained when
• there is a change in job assignment
• 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 employees
  knowledge or use of the energy control procedures

19
Training

• The objective of retraining is
• to introduce new or revised control methods and
  procedures as necessary, and
• to reestablish employee proficiency
• 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

20
Monitoring and Enforcement

• The use of the energy control procedures must be
  periodically monitored.
• The Management will be responsible for the
  implementation and enforcement of this policy.
• Failure to follow this energy control policy will
  result in disciplinary action.
• Disciplinary action may lead to employees
  termination of employment.

21

• Failing to enforce
• these procedures
• could lead to disaster!

22
Annual Review and Inspection

• The hazardous control policy must be reviewed

• Procedures will be updated as necessary
• Employees re-trained as necessary

23
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
• The employees performing the procedure if
  applicable
• The name of the employee performing the
  inspection
• The annual review and inspection must be
  performed by an authorized employee other than
  the one being reviewed.
