        LOCKOUT PROCEDURES FOR THE ELECTRICAL DEPARTMENT

Most of the switches in the Convention Center lend themselves to
being locked out.

1.      When you work on motors or other electrically operated
     equipment, your lockout adaptor should be installed so that
     the circuit you are working on cannot be energized.  Your
     personal unique lock is then installed on the lockout adap-
     tor.  If more than one person is working on the equipment
     being deenergized, then each person involved should place
     their own unique lock through one of the vacant holes on the
     lockout adaptor.  A safety tag should now be placed on the
     switch with the name of the person working on the equipment,
     the date and the nature of the work.  This safety tag can
     only be removed by the person who installed it.

        If it is possible, remove the fuses from switches before
     locking them out.  If the switch has control fuses, remove
     them also, before locking out the switch.  When we have fin-
     ished modifying our panels, the covers will be locked in
     place and the door to the circuit breakers is equipped with
     a hasp to accept a lockout device.  Properly filled in tags
     should always be attached to the lockout device.

        The circuit being worked on must be tested after it is
     switched off to avoid problems from faulty switches or
     stored energy from a capacitor in the circuit.  A capacitor
     circuit cannot be worked on until it has been completely
     discharged.

        The essential ingredient in all lockout procedures is to
     "remove all energy sources which could activate the machine
     by locking the switches out in the off position."

        Panels that have breakers with out lockout hardware on them
     will have a hoop placed on them and will be modified so that
     they can be locked out in the off position.

        All affected persons should be notified that a lockout is
     required and the reason that it needed.

        Some pieces of equipment have more than one device that can
     start the equipment.  All start-up points shall be
     determined by studying the blueprints.  Each point of
     possible start-up must be tagged and locked out.

        The object of this lockout procedure is to eliminate all
     possibilities of an accidental startup of equipment while it
     is being worked on.

        Only Electricians, Senior Electricians, and Electrical
     Supervisors can lockout equipment to be worked on by 
     electrical crews.

        For their own protection and peace of mind, Electrical Craft
     Helpers are provided with unique locks and lockout adaptors
     so that they can add their personal locks to the already
     installed Electrician's adaptors.  Electrical Craft Helpers
     may not initiate or carry out a lockout procedure.

        If the equipment to be worked on is under the control of the
     control room staff, they must be consulted and notified in
     advance of your intentions.  The operator should then log
     all the details in his log and give his O.K. to the electri-
     cal worker to proceed with the lockout.

        To re-energize the circuit, all materials that may cause a
     hazard must be removed.  Belt-guards and guard rails must be
     secured in place and everyone connected with the operation
     must be notified of your intention to restore power to the
     equipment.  All lockout devices can now be removed.  If it
     is under the Control Room's jurisdiction, it must be logged
     as "ready for test".  After testing, it can be logged "back
     in service."

        The parking area switchrooms for show power are being modi-
     fied so that the door can be padlocked.  If electricians are
     working on several panels, (i.e. in move-in), they can se-
     cure the entry door in the switchroom and follow established
     lockout procedures.

        If, for any reason, these procedures cannot be followed,
     check with the Electrical Senior or Supervisor before
     proceeding any further.  Our aim is to make it impossible
     for an accident to occur.  If you find flaws in this system,
     or have suggestions to improve the procedure, by all means,
     let us know.  We will do everything in our power to make
     your working environment 100% safe.
