Emergency free ascent (EFA) is like a controlled emergency swimming ascent without a regulator in the mouth. It is considered unacceptably hazardous for training purposes by some agencies. [6] [7] Emergency swimming ascent (ESA) is a free ascent where the diver swims to the surface at either negative or approximately neutral buoyancy.
The procedures are intended to limit risk of barotrauma of ascent and decompression sickness, while maintaining an efficient ascent profile. One of the most important criteria for a controlled ascent is control of the ascent rate, both during the periods of active ascent (pulls), and periods of staged decompression (stops). [5]

Lost weights ascent with flare – Mitigation of an incident where the diver cannot neutralise positive buoyancy. Controlled buoyant emergency ascent – Fine control of buoyancy to ascend at an acceptably safe rate. Emergency swimming ascents – Emergency ascent where the diver actively swims upward at approximately neutral buoyancy.
When an unforeseen emergency occurs, the diver, and where relevant, the diving team, must make the best of the situation using the skills, knowledge, intelligence and facilities they have available. Many types of emergency are best avoided simply by not diving in circumstances beyond those in which the diver is known to be competent.
