CHAPTER 13 Mixed Gas Operational Planning
Change A 13-11
FINAL PREPARATIONS AND SAFETY PRECAUTIONS
Prior to the start of a mixed gas diving operation, it is important to check that all
necessary preparations have been made and that all safety precautions have been
checked. This ensures that the diving team is properly supported in its mission and
that all possible contingencies have been evaluated in case an unexpected circum-
stance should arise.
Chapter 5 describes the objectives and importance of maintaining accurate
records. The Diving Officer, Master Diver, and Diving Supervisor should identify
the records required for their respective systems and tailor them to suit their needs.
The purpose of any record is to provide an accurate and detailed account of every
facet of the diving operation and a tabulation of supplies expended to support the
operation (e.g., gases, carbon dioxide absorbent, etc.). Any unusual circumstances
regarding dive conduct (i.e., treatments, operational/emergency procedures, or
deviation from procedures) established in the U.S. Navy Diving Manual shall be
brought to the attention of the Commanding Officer and logged in the Command
Smooth Diving Log.
MIXED GAS DIVING EQUIPMENT
There are several modes of diving that are characterized by the diving equipment
used. The following descriptions outline capabilities and logistical requirements
for various mixed gas diving systems.
