6111 Appendix T1

Administrative Control using

Locks and Tags Procedure

 

 

1.0            Purpose

 

This appendix contains the guidelines for implementing administrative controls relating to locks and/or tags to restrict equipment operation, use, or tampering of equipment for reasons other than maintenance, service work, or construction type work activities. LTT activities that require personal protection are described in ES&H Manual Chapter 6110 Lock, Tag, Try (LTT) Program.

 

2.0            Responsibilities

NOTE:     Management authority may be delegated to a task qualified Jefferson Lab employee at the discretion of the responsible manager.

 

2.1              Qualified Individuals

·         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.

 

3.0            Process Steps

Unless otherwise stated only Qualified Individuals may perform the process steps outlined 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.

 

NOTE: 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, service work, or construction type work activities. DO NOT USE Jefferson Lab approved Danger LTT Locks.

o   Prevent unauthorized individuals from inadvertently changing the intended configuration.

o   Multi-lock hasp:

        if additional administrative controls are to be applied

        if another LTT device is to be applied later for maintenance, service work, or construction type work activity

 

DO NOT USE:

 

·         Tags:

o   Are clearly distinguishable from those used for maintenance, service work, or construction type work activities. DO NOT USE Jefferson Lab approved Danger Tags.

o   Affixed so they are immediately apparent to anyone who might attempt to operate the device.

 

USE:

DO NOT USE:

Back                                      Front

 

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, by durable means to the shackle of the accompanied lock, or a non-reusable method capable of withstanding a 50-pound pull, minimally equivalent to a nylon cable tie.

 

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.

 

NOTE: The removal of equipment, that has lock(s) and/or tag(s) attached to it, constitutes a removal of the lock(s) and/or tag(s); therefore all lock(s) and/or tag(s) shall be removed by their owners (or anyone listed on the tag as an authorized individual) before work is performed on the equipment.

 

3.1              Transition from Administrative Lock and/or Tag to Danger LTT

Administrative locks and/or tags securing equipment must be replaced or augmented with LTT locks/tags during maintenance, service, or construction type work activity to ensure all energy sources are secure. This is done in accordance with ES&H Manual Chapter 6110 Lock, Tag, Try (LTT) Program.

 

3.2              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.
