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

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 dive suyed and meets the requirements of step 4.3.5

7.

Verify helmet dosimetry attached with wire/pdastic ties, when applicable. Do not use material, such as plastic bags or tape, which could block diver's exhalation valve.

1. Verify diver dosimetry in proper location (e.g, EDs, TLDs, Extremity, etc.).

9. Verify remote dosimetry equipment is operational.
