NF 57-03-29 Closed Circuit Rebreather (CCR) Decompression Diving Request

What: This document is the principle form used by the NDCSB to review and approve closed circuit rebreather (CCR) decompression dives. It is prepared by a UDS (or designee) and submitted to the respective LODO or SODO who brings it to the NDCSB. There is a lengthy checklist outlining equipment, training, and operational requirements, a section for describing any negative responses to the checklist items, a section for narrative descriptions of the dive team and planned operations and concludes with a section on emergency procedures.

When: This document should be submitted to the LODO / SODO at least one (1) month prior to the beginning of the requested operation. This lead time is required to allow the NDCSB sufficient time to thoroughly review the plan and request clarification of any component which the Board has concerns about.

Record keeping: This document should be retained by the UDS until the completion of the requested dive(s).
