Divers often work in open sea, but they also work oftenly in very confined spaces. That is why we organised a thorough training for all our divers, so they can enter confined spaces safely. The training was an eye-opener for everyone. Especially when we were trained to remove a victim from a confined space, everyone realised how difficult it can be. The victim and the instructor remained calmly, but we were sweating like crazy.
We think this training is a must for all professional divers. It should even be compulsory as part of the professional training of professional divers.
