Lost Bell Survival

Diving bells receive all their vital resources such as breathing gas and power via an umbilical cable. In the rare event, that both this cable and the lifting wire are severed, an emergency battery will kick in, but it will not be powerful enough to provide heating. As a result, divers will be at risk from potentially fatal hypothermia.

In a new video available through IMCA, divers are reminded about the importance of using both survival bags and an individual gas heating and scrubbing unit if they find themselves in such a position.

The video opens with a simulated 'lost' bell emergency and shows two divers responding in the right way.
