Compliance Training Presentation

NPCA Safety, Health and Environmental Committee


Disclaimer

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.


Purpose

Purpose

  • 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, 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.


Definitions

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.


Definitions cont

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.


Definitions1

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.


Exemptions

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.


General requirements

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 requirements1

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 requirements2

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 requirements3

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

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 loto1

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


Removal of loto

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 loto1

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


Additional instructions

Additional Instructions

  • When the authorized employee is not available, the following actions may be taken:

    • Make a reasonable attempt to contact the authorized employee.

    • Remove all tools and material from the equipment area.

    • Make sure all affected employees are clear of the area.


Additional instructions1

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 device.


Training

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.


Training1

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

    • 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


Training3

Training

  • The objective of retraining is:

    • to introduce new or revised control methods and procedures as necessary, and
