Scuba gas planning is the aspect of dive planning which deals with the calculation or estimation of the amounts and mixtures of gases to be used for a planned dive profile, and can be critical to the safety of the dive. The scuba diver by definition is independent of surface supply and, in general, must carry all gas needed for the dive, though ...
The emergency plan, (or emergency action plan), should be specific to the dive plan where applicable, as specific actions should be detailed where possible and depend on the circumstances of the dive plan. As much detail as reasonably practicable can save time during an emergency, when it avoids the need to make detailed plans at the time.

The IDSA training standard comprises 5 modules, of which Module A is theory common to all modes of diving, Module B is commercial scuba diving, Module C is inshore air diving to 30 msw and associated underwater work, Module D is surface supplied offshore air diving to 50 msw using a wet bell and hot water suit, also called extended range ...
The dive plan must be understood and followed, and contingency plans should be available for the foreseeable deviations from the plan. [32] DIR divers must be completely dedicated to the buddy system, primarily in the interest of safety, but also because failure to follow the expected procedures is likely to compromise the dive plan.
The RDP was developed by DSAT and was the first dive table developed exclusively for no-stop recreational diving. [2] There are four types of RDPs: the original table version first introduced in 1988 along with a circular slide rule version called The Wheel, followed by the eRDP, an electronic version introduced in 2005 and the eRDPML, an ...
Buddy checks may be extended to include aspects of dive planning, to ensure that the divers are agreed on the intended activity and contingency plans. When larger groups and more complex dive plans are involved this would be considered part of the dive briefing. Risk assessment update; Emergency plans; Contingency plans
The formal and relatively complete procedure for scuba gas planning assumes that a dive plan is available that is sufficiently detailed that most of the variables are known. many recreational dives are conducted on a more ad hoc basis where the dive is planned and conducted around the available gas.
