RP-AA-461 Revision 2 Page 20 of 23 ATTACHMENT 3 Pre-Dive Checklist Page 1 of 1 (USED FOR SUBSEQUENT DIVES AFTER CREW'S INITIAL BRIEF. MAY BE PERFORMED IN ANY ORDER)
I -~ '" ,4 " - I ý a I
- 1. Complete a pre-job briefing (discussion to include dive area boundanes, dose rate information and task(s)). -;we
- 2. Verify two underwater survey instruments are in calibration and source checked and are available. W'O"
- 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
- 7. Verify helmet dosimetry attached with wire/plastic ties, when applicable. Do not use material, such as plastic bags or tape, which could block diver's exhalation valve.
- 9. Verify remote dosimetry equipment is operational.
- 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 Red 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 byDive Supervisor and priorto notifiation to RP/Safety)
- 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.
