1. SLAC Radiation Safety Work Control Form Process:
A means of managing safety system configuration control
Zoe Van Hoover: August 22, 2018

2. Radiation Safety Work Control Form
RSWCF is used to manage work on configuration controlled radiation safety systems at SLAC:
Personnel Protection System (PPS)
Beam Containment System (BCS)
Shielding

3. Radiation Safety Work Control Form
Each SLAC organizational unit responsible for operating an accelerator facility has a RSWCF process
Accelerator Facility
Operations Organization
RSWCF
Two Mile Linac Facility
&
SPEAR-3 Accelerator
Accelerator Operations and Safety Division
Electronic Form
LCLS Experimental Areas
LCLS
Paper Form
SSRL Experimental Areas
SSRL
NLCTA and ASTA
AD Test Facilities
RSWCF format and minor details vary for each facility, but the process is the same across the lab.

4. Radiation Safety Work Control Form
Step 1: Identify work that requires a RSWCF.
Labeling
Training
CATER* integration
ADSO and Area Manager of new CATER entries
* CATER = Computer Assisted Trouble Entry and Reporting

5. Radiation Safety Work Control Form
Step 2: Designate “Person Responsible,” initiate a RSWCF, describe radiation safety implications of work, and get Area Manager approval to proceed with work planning.
Person Responsible:
Directly doing or overseeing work
Understands:
Scope of work
Radiation safety implications
RSWCF process
Responsible for only allowing work when RSWCF is in the “Work Approved” state.

6. Radiation Safety Work Control Form
Step 3: ADSO completes “Requirements Before Starting Work” and “Work Completion Requirements. ADSO and RP sign. Person Responsible Signs.

7. Radiation Safety Work Control Form
Step 4: Operator In Charge (OIC) ensures that requirements before starting work are met, then signs to move the RSWCF to “Work Approved.”
Hold a PPS key in a keysafe
Padlocks in place locking off hazard
Stoppers disabled
Step 5: Do the work!

8. Radiation Safety Work Control Form
Step 6: Person Responsible or Area Manager complete work completion fields.

9. Radiation Safety Work Control Form
Step 7: ADSO reviews work completion fields and moves form to “Work Complete” state.
Step 8: OIC reviews and signs to move RSWCF to the “Closed” state. Hazard controls may now be revoked.
