A diving emergency or underwater diving emergency is an emergency that involves an underwater diver.The nature of an emergency requires action to be taken to prevent or avoid death, injury, or serious damage to property or the environment.
Saturation diving is normally done from a saturation system on a diving support vessel or an offshore platform.While under saturation, the divers cannot be decompressed quickly in response to an emergency as that would be rapidly fatal, and though unusual, emergencies requiring personnel evacuation have occurred on such platforms due to extreme weather or accidents.
An emergency ascent implies that the dive plan has been abandoned due to circumstances beyond the control of the diver, though they may have been caused by the diver, as is often the case in out-of gas emergencies in scuba diving. [1] Out of gas emergencies are generally the most urgent contingencies in diving, as the available time to deal ...
Providing emergency gas to a diver who has run out is the highest priority after finding the diver. Without breathing gas the diver will die in minutes. Running out of gas is a major contributor to diving accidents. Many scuba accidents start in some other way and culminate in running out of gas.
These conditions present similar symptoms and require the same initial first aid. Scuba divers are trained to ascend slowly from depth to avoid DCI. Although the incidence is relatively rare, the consequences can be serious and potentially fatal, especially if untreated. [1]
The procedures vary depending on whether the diver is using scuba or surface supplied equipment. Scuba divers control their own descent and ascent rate, while surface supplied divers may control their own ascents and descents, or be lowered and lifted by the surface team, either by their umbilical, or on a diving stage, or in a diving bell.
ENOS is designed for emergencies associated with a diver(s) surfacing too far from the boat to swim back. For example, when divers have been swept away from their vessel by a current or when they can't see the boat because of poor weather. To send an emergency signal, the diver switches on the transmitter.
Public safety diving team members bring in a casualty Controlling an underwater search from the jetty. Underwater search and recovery is the process of locating and recovering underwater objects, often by divers, [1] but also by the use of submersibles, remotely operated vehicles and electronic equipment on surface vessels.
