3330 Appendix T1

Suspend Work for Safety Procedure



1.0             Purpose


Suspend work occurs when a hazard issue is discovered or anticipated that may endanger individuals, equipment, or the environment if the activity continues. Work is suspended until mitigation measures are implemented or a new, safer, work plan is developed.


2.0             Scope


Suspend work is used when an unanticipated hazard issue develops during work in-progress. It may also be used during a Safety Observations according to 3700  Safety Observation Program or during formal inspections. 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.


The process steps outlined below 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

·         An activity is observed that:

o   Appears to be inconsistent with an existing THA, work control document or AHA for subcontracted construction activities.

o   Appears to be inconsistent with recognized safe work practices.

·         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:            Suspend Work

·         The person who identifies the safety concern asks involved workers to suspend their activities. The Risk Code associated with the identified safety concern would typically be less than RC 3.

·         The person initiating the suspend work notifies or ensures that the supervisor/Subcontracting Officer’s Technical Representative (SOTR)/sponsor has been notified that work has been suspended. SOTRs see Chapter 3410 Subcontractor Construction Safety, Section 4.12, Stop Work and Restart for Safety Program for suspend work related to subcontracted construction activities.


Step 3:            Prepare On-The-Spot Solution

·         Confer with workers, supervisor/Subcontracting Officer’s Technical Representative (SOTR)/sponsor to develop an “on-the-spot” solution that eliminates the safety concern.

·         Affected workers, supervisory staff, person initiating the suspend work concur in the solution.


Step 4:            Implement Solution

Worker’s supervisor/SOTR/sponsor ensures that implemented safety measures are effective and 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.
