||
|
|
|||
This appendix contains the guidelines for implementing administrative
controls relating to locks and/or tags to restrict equipment operation,
access, use, or tampering for reasons other than maintenance or service
work. Activities that require personal
protection during maintenance and service work are described in ES&H
Manual Chapter 6110 Lock, Tag, Try (LTT) Program.
NOTE: Management authority may be delegated at the discretion of the responsible manager.
·
Current in SAF 104 Lock, Tag, and Try
· Identify yourself and/or your work group on an applied
administrative lock and/or tag; unless ownership is apparent.
· Remove only those locks or tags that you apply or have been listed
as an authorized individual.
·
Recognize and respect all
administrative lock and tag control measures.
Unless otherwise stated only Qualified Individuals may
perform the process steps listed below.
3.1
Apply Administrative Locks and Tags:
Step 1: Clearly identify the configuration of the equipment or system to be controlled
Do not proceed until you are certain of all the hazards associated
with the operation of the equipment or system and the proper configuration for
control. Information regarding the item
is available from many sources including:
·
written procedures,
·
blueprints,
·
system diagrams,
·
operating manuals, and
·
owners of the
equipment
|
Be alert to multiple energy sources. |
Step 2:
Notify Others
Appropriately coordinate with all affected groups and/or individuals before locking or tagging the equipment.
Step 3: Configuration Control
·
Ensure the Qualified
Individual’s name (or working group) is displayed; unless ownership is
obvious. (Name all individuals or groups
authorized to modify the administrative lock and/or tag).
· Locks:
o
Are clearly
distinguishable from those used for maintenance or service work (LTT). (Do not use
Jefferson Lab approved LTT Locks.)
o
Prevent unauthorized
individuals from inadvertently changing the intended configuration.
o
Multi-lock hasp if
another LTT device is to be applied later for maintenance or service work.
DO NOT USE:
·
Tags:
o
Are clearly
distinguishable from those used for maintenance or service work (LTT). (Do not use
Jefferson Lab approved Danger Tags.)
o

Step 4: Affix Administrative Lock and/or Tag
· Place the equipment or system into the intended state.
·
Attach an appropriate
administrative lock and/or tag. (Attached
by a durable means e.g. cable tag.)
Step 5: Verify Effectiveness
· When appropriate, have an independent qualified individual verify
the effectiveness of the administrative control to ensure the equipment is in
the desired state.
Step 6: Removal of Administrative Locks and/or Tags[1]
·
An authorized individual
notifies all affected parties prior to the action.
·
When all affected individuals
are ready, an authorized individual may remove the administrative lock and/or
tag.
3.2
Transition
from Administrative
Lock and/or Tag to LTT
Administrative locks and/or tags securing equipment
must be replaced or augmented with LTT locks/tags during maintenance or service
work to ensure all energy sources are secure.
This is done in accordance with ES&H Manual Chapter 6110 Lock, Tag, Try
(LTT) Program.
3.3
Special
Administrative
Lock or Tag Removal[2]
Use ES&H
Manual Chapter 6110 Appendix T2
Special Lock and Tag Removal Procedure to remove administrative
locks or tags whose owners cannot be located.
