The Hazmat suit is not only the armour of anonymous worker-samurai, it is also their shroud and coffin. They die in there - from pride, over zealous sense of duty, macho determination, lack of training, inadequate supervision, insufficient back-up, poor executive planning, stingy allocation of funds to do the job at hand.

They die from weary old hearts working on a heart-breaking task in a heart-broken district of Japan.
The ghosts of Fukushima are already released. They already haunt the land.
