1. Complete a pre-job briefing (discussion to include dive area boundaries, dose rate information and task(s)).

2 Verify two underwater survey instruments are in calibration and source checked and are available. ,* ,

3, Verify water clarity and underwater lighting adequate.

4, Verify dive site survey is performed (historical survey available for initial dive) and methodology by RP Supervision approved.

5. Verify dive suit is wet prior to diving.
6. Verify diver's suit(s) is surveyed and meets the requirements of step 4.3.5 / , A//* '.t I
7. Verify helmet dosimetry attached with wirelplastic ties, when applicable. Do not use material, such Fi/,

as plastic bags or tape, which could block diver's exhalation valve.

8. Verify diver dosimetry in proper location (e.g., EDs, TLDs, Extremity, etc.).
9. Verify remote dosimetry equipment is operational...d,) A .. v.-l 4 , "_
10. Verify two-way voice communications are available and operational.
11. Verify approved method of visual contact is available.
12. Verify survey instrumentation used by diver is operable.
13. Verify in-leakage test of diver suit has been performed.
14. Verify that breathing air is monitored.
15. Evaluate the need for vacuuming and shielding.
16. Ensure all prerequisites of RP-AA-461 are met prior to dive operations.
17. Discuss immediate actions for each the following: CO alarm, High Rad alarm, CAM alarm, diver disorientation, diver signaled to leave, failure of underwater survey instrumentation, diver reaches pre-established dose limits, radiological aspects of dive can NOT be maintained or are suspect
18. Discuss when the dive operations shall be suspended as per step 4.4.7.
19. Verify with Diver Supervisor that Ops Shift Supervision has been notified prior to start of dive evolutions.
20. Ensure appropriate controls are in place for dive evolutions in a high dose rate gradient area.
21. Ensure water are within limits. (<95-F unless approved byDiveSupewisor and priortonoiication toRPISarety)
22. Discuss approved dose levels with divers.
23. When meeting the requirements of step 3.3.11, ensure a documented plan exists with the appropriate approvals when evaluating diver safety.
