DIVER'S INITIAL CONCERN is an acronym for the four main safety considerations a diver should take before entering the water. The acronym stands for Depth, Injuries, Visibility, Equipment, and Responsibilities. Depth refers to the maximum depth a diver should go, Injuries refer to any pre-existing medical conditions that could be exacerbated by diving, Visibility is the clarity of the water, Equipment is the condition of the diver's gear, and Responsibilities are the tasks the diver should complete while underwater.
