When a freight ship loses control of its anchor, bad things happen

This video appears to be a freighter's anchor being lost as it is dropped. The situation just gets worse and worse as the chain's momentum increases and whatever braking mechanisms exist fail. Soon, metal is on fire, and it seems clear that it is now time to back away from the gigantic runaway anchor chain whose back end components are likely to go places unknown when they emerge from the ship. Yet our intrepid shooter keeps filming!

I see no gloves, goggles, hard hats or fear, and thereby suspect this involves Russians.
