ES&H Manual



6683 Appendix T2

Silica Training



Jefferson Lab has determined that working with silica carries an unmitigated Risk Code >2.  At a minimum all tasks involving silica are discussed with the supervisor prior to commencement.  An Operational Safety Procedure (OSP) is written for any work considered to be Risk Code >2 in accordance with ES&H Manual Chapter 3210 Work Planning, Control, and Authorization Process.


1.0            Purpose


No one at Jefferson Lab, including subcontractors, may authorize or perform work unless they are properly trained.  This appendix presents the process steps used to obtain and record the training required for work involving silica. 


2.0            Scope


SAF138 Silica Dust Hazards in Construction, or equivalent, is required every three years and includes procedures and requirements relate specifically to activities known to generate silica hazards at Jefferson Lab.  Training includes hazard assessment and appropriate mitigation techniques.


Prior to commencement of work, subcontractors either provide, for review and acceptance, their silica safety program and their personnel’s training records; or use Jefferson Lab’s program.  


Depending on the complexity of the activity (i.e. indoors, confined space), Industrial Hygiene may require "hold points" to verify control adequacy (e.g. engineered, Personal Protective Equipment (PPE)). Involve Jefferson Lab Industrial Hygiene in work planning activities. 


The process steps for this procedure are performed in coordination with ES&H Manual Chapter 6683 Silica Safety Program.


3.0            Responsibilities

NOTE:           Management authority may be delegated at the discretion of the responsible manager.


3.1              Trained Worker

·         Complete and maintain appropriate training

o   SAF138 Silica Dust Hazards in Construction, and

o   Medical monitoring, as appropriate.


3.2              Supervisor/Subcontracting Officer’s Technical Representative (SOTR)/Sponsor:

·         Assign only Trained Workers to silica work.


3.2.1        SOTR also:

·         Inform subcontractors that their Activity Hazard Analysis (AHA) must include the planned technique(s) to mitigate silica exposure and the program used to train workers.  (Minimally to Jefferson Lab requirements.)  

·         If provided, submit subcontractor’s silica AHA to Jefferson Lab’s Silica Subject Matter Expert (see ES&H Manual Chapter 2410 Appendix T1 Hazard Issues List – Silica) for approval prior to commencement of work. 


3.3              Silica Subject Matter Expert (SME)

·         Oversee the on-site silica training program.

·         Make silica equivalent training determination. 

·         Maintain listing of Trained Workers in accordance with ES&H Manual Chapter 4200 ES&H Training Overview.


4.0            Process Steps


4.1              Silica Training

Unless otherwise stated anyone at Jefferson Lab may take this training.  It is required for those individuals who have been recognized by their supervisors to work in or around silica hazard areas:


Step 1:             Review on-line training module:


Step 2:             Update Skills Requirements List (SRL) – Upon successful completion of the course, fill in the requested information to update your Skills Requirements List.


4.2              Equivalent Training Determination

The Silica Subject Matter Expert (SME) has the authority to make a determination that silica training obtained elsewhere is equivalent to Jefferson Lab training.


Step 1:             The Supervisor/SOTR submits training equivalency documentation to the Silica SME.


Step 2:             The Silica SME reviews and determines whether the training is equivalent to that of Jefferson Lab’s requirements, and provides a determination to the Supervisor/SOTR.


Step 3:             The Supervisor/SOTR updates the individual’s SRL to reflect the determination.


5.0            Revision Summary


Revision 0.1 – 01/07/16 – Section 2 Scope: Added direction to include IH in work planning.

Revision 0 – 06/08/12 – Update to reflect current laboratory operations.
