WAC 296-803-50005
Use energy control procedures

You must

  • Use energy control procedures to protect employees servicing or maintaining machines and equipment from potentially hazardous energy.
  • Use a lockout system if an energy-isolating device can be locked out.
Exemption

Exemption:

  • A tagout system may be used instead of a lockout system if it meets all of the following:
    • – The tagout device is attached where you would have put the lockout device
    • – The tagout system provides the same level of employee protection as a lockout system
    • – You can demonstrate that the tagout system:
      • Meets all tagout requirements of this chapter
      • Includes additional safety measures to provide the same level of safety as a lockout system.

Note

Note:

  • Additional safety measures used with the tagout system to provide protection equal to a lockout system could include actions such as:
    • – Removing part of the isolating circuit
    • – Blocking a controlling switch
    • – Opening an extra disconnecting device
    • – Removing a valve handle.

You must

  • Use a tagout system if an energy-isolating device can't be locked out.

WAC 296-803-50010
Meet these requirements when applying lockout or tagout devices

You must
  • Make sure, before a machine or equipment is turned off, that the authorized employee knows all of the following:
    • – Type and magnitude of the energy
    • – Hazards of the energy to be controlled
    • – Method or means to control the energy
  • Turn off or shut down the machine or equipment using established procedures. An orderly shut down is necessary to avoid any additional or increased hazard to employees as a result of the equipment stoppage.
  • Completely isolate the machine or equipment from its energy sources using the appropriate energy-isolating devices after the machine or equipment has been turned off.
  • Make sure you or the authorized employee notify affected employees that the machine or equipment is being locked or tagged out before the devices are applied.
  • Make sure a lockout or tagout device is applied:
    • – For each energy-isolating device
    • – Only by the authorized employee doing the service or maintenance.

WAC 296-803-50015
Meet these additional requirements when applying lockout devices

You must
  • Make sure lockout devices hold the energy-isolating device in a “safe” or “off” position.

WAC 296-803-50020
Meet these additional requirements when applying tagout devices

You must

  • Make sure a tagout device is put on an energy-isolating device so it clearly shows that moving the energy-isolating device from the “safe” or “off” position is prohibited.
  • Make sure a tagout device, when used with an energy-isolating device that can be locked out, is fastened to the device at the same point a lock would have been attached.
  • Make sure a tagout device that can't be attached directly to an energy-isolating device is located:
    • – As close as safely possible to the energy-isolating device;
      and
    • – In a position that is immediately obvious to anyone attempting to operate the energy-isolating device.

WAC 296-803-50025
Protect employees from the hazards of stored and residual energy

You must

  • Make sure all potentially hazardous stored and residual energy is relieved, disconnected, restrained, or otherwise rendered safe after the lockout or tagout devices have been put on the energy-isolating devices
  • Continue to verify the isolation of machines and equipment that could reaccumulate stored energy to a hazardous level until:
    • – Service or maintenance is completed
    • – The possibility of reaccumulating hazardous energy doesn't exist.

WAC 296-803-50030
Verify that the machine or equipment is safe before starting work

You must

  • Make sure the authorized employee verifies that the machine or equipment that’s been locked out or tagged out has been isolated from all energy sources and deenergized before starting work.

WAC 296-803-50035
Meet these requirements when removing lockout or tagout devices and energizing the machine or equipment

You must

  • Make sure the authorized employee does the following before removing any lockout or tagout device:
    • – Inspects the work area to make sure nonessential items have been removed
    • – Verifies the machine or equipment is in operating condition and ready to energize
      and
    • – Check that employees in the area are in positions that make it safe to energize the machine or equipment.

• Make sure only the authorized employee who applied a lockout or tagout device removes it.

      Exemption

      Exemption:

      • The employer may have the lockout or tagout device removed by someone other than the authorized employee who applied it if all of the following conditions are met:
        • – The energy control program has documented, specific procedures and training for this situation
        • – You can show that the specific procedures used are as safe as having the device removed by the authorized employee who applied it
        • – The specific procedures include at least the following:
            • Verifying the authorized employee who applied the device isn't at the facility
            • Making all reasonable efforts to contact and inform the authorized employee that the lockout or tagout device is being removed
            • Making sure the authorized employee is informed, before resuming work at the facility, that the lockout or tagout device has been remove

You must

  • Do the following before energizing or starting the machine or equipment:
    • – Notify affected employees that the lockout or tagout devices have been removed.
