Dive first aid kits are specialized medical kits designed to address common injuries and emergencies that may occur while diving. They include items such as bandages, antiseptics, ointments, and medical tools for treating cuts, abrasions, or other minor injuries. Some kits also contain oxygen or specialized gear for dealing with decompression sickness. Regular checks and replenishment of supplies are necessary to keep the kit ready for use. Training in first aid and emergency procedures is also important to ensure proper use of the kit in critical situations.
