exit the water, usually by finning at the surface Exit from water Un-kit (dressing out) – Removal of diving equipment worn and carried by the diver Log dive – Recording specific details about the dive in a diver's logbook (paper or electronic database) Clean, inspect and store equipment – Basic daily user maintenance. Pack up site Routine Surface-supplied diving procedures: Preparing the surface supplied diving equipment Dressing in the diver – Dressing into the diving suit, harness, bailout set, helmet or full-face mask and accessories Pre-dive checks - Checks that all necessary equipment is correctly fitted and functioning Demisting the faceplate – getting rid of condensation droplets on the inner face of the viewport to improve vision. Clearing a flooded helmet or full-face mask – Expelling water which found its way into the interior space and can hinder safe breathing. Adjusting the breathing resistance – adjusting inhalation and exhalation pressure differences to reduce the work of breathing of a demand regulator. Voice communication – Use of standard voice protocols to facilitate accurate and reliable communication. Rope signals – Use of standard code of pull signals transmitted via the lifeline or umbilical when voice is not available Umbilical management – Keeping slack, twists, and snags from the route of the umbilical to the diver In-water decompression – Fully decompressing in the water Surface decompression – Leaving the water before fully decompressed and recompressing in a chamber to finish the decompression in relative comfort. Routine wet bell procedures (some of these procedures also apply to closed bell operations, though details will differ): Preparation of the bell – Preparation of the bell for the dive and testing the bell systems. Descent and ascent - Lowering the bell to working depth and raising it at the end of the dive, with appropriate in-water decompression stops. Lock-out – Deployment of the diver(s) from the bell at working depth. Bell integrity check at the bottom – Brief inspection of the exterior of the bell before the diver leaves the immediate vicinity. Monitoring at the bell - Monitoring of the bell and environs and of the working diver's umbilical by the bellman. Umbilical management – Management of the diver's umbilical by the bellman. Operation of the wet bell gas panel – In-water tending - Additional management of the diver's umbilical by an in-water tender where necessary Securing the bell for ascent – Stowing of umbilicals on the
