submarine escape techniques

Submarine escape techniques involve specialized procedures for crew members trapped underwater. They typically use a submarine escape suit, which helps with buoyancy and pressure, and a built-in breathing apparatus. The crew enters an escape vessel or hatch, then seals and descends to a safe depth, often around 30 meters. At this point, they equalize pressure, open the hatch, and escape individually through a compressed-air chamber or hatch, ascending slowly while controlling buoyancy. Upon reaching the surface, they inflate their suits and are rescued. These techniques are critical for survival in emergencies, combining carefully managed pressure, buoyancy, and safety protocols.
