Abstract:
1. A safety method in connection with self contained underwater breathing apparatus (SCUBA) diving to control a diver's buoyancy, the method comprising: equipping the diver with diving equipment comprising at least one air pressure tank, a valve device connected to the pressure tank and arranged to supply air from said pressure tank via first supply means to a breathing regulator and via second supply means to an inflatable diving jacket in order to control the diver's buoyancy, an actuator being able to automatically initiate inflation of the diving jacket when the diver has not affected an air flow through the breathing regulator for a certain time period, wherein said actuator is controlled by an actuation mechanism that automatically sets the actuator in active mode when the diver is within an actuation zone, wherein said actuation zone is defined by an upper actuation depth and a lower actuation depth, and said upper actuation depth is positioned immediately below a water surface to 1.0 m below the water surface.
