As is often the case we will never know exactly what happened in this case and yet can still get insight from this unfortunate accident. One possibility based on what we have been told is that he tied himself to a line before descending. If that line was tied in a way that was not able to be reached while diving then that is something we should obviously avoid.
If there was no cutting tool available to free an entanglement then that is certainly something we can avoid. I take two cutting devices on every dive. I see no reason to change that even if I'm in a pool. I put my hands on them on every dive. My hands should know how to instinctively find them while my attention is focused on other matters.
If the line that he was said to be tethered to was in fact a submerged line he had no knowledge of beforehand and it was simply tangled on a suicide clip or regulator then that is also something we can work to avoid while again always having cutting tools available.
