3330 Appendix T1

Suspend Work for Safety Procedure



1.0            Purpose


Suspend work occurs when a hazard issue is discovered or anticipated that endangers individuals, equipment, or the environment.  Work is stopped until mitigation measures are implemented or a new, safer, work plan is developed.


Perform any emergency response actions required prior to performing the process steps outlined in this procedure.


2.0            Scope


Suspend work is used when an unanticipated hazard issue develops during work in-progress.  All parties agree with the mitigation measures; but work must be suspended until the measures are implemented. 


This procedure does not take the place of “common-sense.”  Suggestions, recommendations, or other forms of communications, which takes place on a day-to-day basis between individuals and provide “on the spot resolutions” to safety concerns, are not required to be formally documented.


This appendix’s process steps are performed in coordination with ES&H Manual Chapter 3330 Stop Work and Re-Start for Safety Program.


3.0            Process Steps


Step 1:             Identify Concern or Operational Upset

·         Does the concern pose an operational upset? Imminent danger? Risk Code >3?

o   Yes:

§  Implement containment actions or emergency response procedures.

§  Go to ES&H Manual Chapter 3330 Appendix T2 Stop Work Order for Safety Procedure.

o   No – Go to Step 2.


Step 2:             Imminent Danger

·         Is this an off-normal operation or failure of equipment that poses a imminent danger to laboratory operations?

o   No – If an “on-the-spot” solution can be implemented, do so, and go to Step 4.

o   Yes – Work is suspended.

§  The worker notifies their supervisor/Subcontracting Officer’s Technical Representative (SOTR)/sponsor that a Suspend Work Order has been initiated.

§  The identifier notifies their supervisor/SOTR/sponsor that they have initiated a Suspend Work Order.

§  Go to Step 3.


Step 3:             Task Hazard Analysis (THA) Required

·         Worker’s supervisor/SOTR/sponsor completes a THA for the identified concern.

o   Outcome Risk Code <2 – Does this resolve the issue?  The initiator must agree that the identified concern has been adequately addressed.

§  Yes – Go to ES&H Manual Chapter 3330 Appendix T4 Work Re-Start Procedure.

§  No – Stop Work.  See ES&H Manual Chapter 3330 Appendix T2 Stop Work Order for Safety Procedure.

o   Outcome Risk Code >3 – Stop Work Order initiated.  Go to ES&H Manual Chapter 3330 Appendix T2 Stop Work Order for Safety Procedure.


Step 4:             Resume Work

Worker’s supervisor/SOTR/sponsor ensures that implemented safety measures continue to be used.


Step 5:             Feedback and Lessons Learned

Worker’s supervisor/SOTR/sponsor provides Jefferson Lab relevant information regarding the Suspend Work activities using the Jefferson Lab’s Corporate Operating Experience (COE) website.
