Ascent and Arrival to the Surface
The climb should always be made with the companion and the climbing speed indicated on the table or on the computer used must always be respected.
When approaching the surface, the diver should look around to make sure there are no obstacles that make it difficult to exit and raise the arm to protect the head from any blow and signal the presence .
On the surface you should look around to locate the companions and the boat and to check if there is traffic on the surface (especially attention to windsurfboards that do not make noise). Make the “I’m fine” sign (OK) to the boat, by hand or, if it’s far away, with your arm over your head to be more visible.
Under no circumstances should breathing be blocked during the ascent in order to avoid pulmonary overpressure.
