Sequence of Lockout/Tagout System Procedure

  1. The authorized employee will notify all affected employees that a lockout or tagout system is going to be utilized and the reason therefore. The authorized employee shall know the type and magnitude of energy that the machine or equipment utilizes and understand the hazards associated with it.
  2. If the machine or equipment is operating, it will be shut down by the normal stopping procedure (depress stop button, close toggle switch, etc.).The shutdown procedure is detailed in the Wind Tunnel Operations Manual.
  3. The authorized employee will operate the switch, valve, or the energy isolating device(s) so that the equipment is isolated from its energy source(s).

 

    3To isolate power to the Wind Tunnel motor drive system, the authorized employee will move the main disconnect handle to the “OFF” position.  This will remove power to the main motor drive system.

 

 

    4To isolate the power to motor bearing lubrication system only, the authorized employee will move the disconnect handle to the “OFF” position.

 

 

  1. All electrical equipment isolation will be verified with electrical meter testing. Stored energy (such as that in springs, elevated machine members, rotating flywheels, hydraulic systems, air, gas, steam, water pressure, etc.) must be dissipated or restrained by methods such as repositioning, blocking, bleeding down, etc.
  2. Lockout and tagout the energy isolating devices with authorized and assigned individual lock(s) or tag(s). Additionally, all other safety methods or procedures shall be indicated on the standard lockout tag.
  3. The authorized employee shall check to ensure that no personnel are exposed to energy sources.
  4. The authorized employee shall operate the switch or the normal operating controls to make certain that the equipment will not operate and ensure disconnections.
  5. The authorized employee will then return operating controls to the “neutral” or “OFF” position after the test.

    The operating controls are detailed in the Wind Tunnel operations startup and shutdown procedure manual located at the operators station.

  6. The equipment is now locked out or tagged out for servicing or maintenance.

 Procedure for restoring equipment to operational status

  1.  After the service or maintenance is complete and equipment is ready for normal operations, the authorized employee will survey the area around the machines or equipment to ensure that no one is exposed to potential energy sources.
  2. After all tools have been removed from the machine or equipment, guards have been reinstalled and employees are in the clear, the authorized employee may remove all lockout or tagout devices.
  3. The authorized employee shall operate the energy isolating devices to restore energy to the machine or equipment.
    1. On the main motor drive system, move the disconnect handle to the “On” position.
    2. On the motor bearing lubrication, move the disconnect handle to the “On” position.

Sequence of Lockout/Tagout System Procedure

  1. The authorized employee will notify all affected employees that a lockout or tagout system is going to be utilized and the reason therefore. The authorized employee shall know the type and magnitude of energy that the machine or equipment utilizes and understand the hazards associated with it.
  2. If the machine or equipment is operating, it will be shut down by the normal stopping procedure (depress stop button, close toggle switch, etc.).

    The shutdown procedure is detailed in the operations manual.

    The shutdown procedure is detailed in the operator’s checklist.

  3. The authorized employee will operate the switch, valve, or the energy isolating device(s) so that the equipment is isolated from its energy source(s).

    7To isolate power to the Compressor DC motor drive system and the lubrication pump system the authorized employee will move the main disconnect handle to the off position.

 

 

 

 

 

    8To isolate the power to the motor control system only, the authorized employee will move the drive disconnect handle to the off position.

 

 

 

 

 

 

    9To isolate the power to the gear box lube pump system only, the authorized employee will move the Gearbox Lubrication Pump disconnect handle to the off position.

 

 

 

 

 

  1. All electrical equipment isolation will be verified with electrical meter testing. Stored energy (such as that in springs, elevated machine members, rotating flywheels, hydraulic systems, air, gas, steam, water pressure, etc) must be dissipated or restrained by methods such as repositioning, blocking, bleeding down, etc.
  2. Lockout or tagout the energy isolating devices with authorized and assigned individual lock(s) or tag(s). Additionally, all other safety methods or procedures shall be indicated on the standard lockout tag.
  3. The authorized employee shall check to ensure that no personnel are exposed.
  4. The authorized employee shall operate the switch or the normal operating controls to make certain that the equipment will not operate and ensure disconnections.
  5. The authorized employee will then return operating controls to the “neutral” or “off ” position after the test.
  6. The equipment is now locked out or tagged out for servicing or maintenance.

 

Procedure for restoring equipment to operational status.

  1.  After the service or maintenance is complete and equipment is ready for normal operations, the authorized employee will survey the area around the machines or equipment to ensure that no one is exposed.
