Let's see, that would be about three inches per hour. Was this reinforced concrete? Seems like it should have gone faster. They only have one saw blade?From the FDNY Facebook page:
"FDNY members responded to a customer trapped in a vault at 580 Fifth Avenue in Manhattan late Tuesday night.
The vault – which has large concrete walls, steel re-enforcing bars and steel plating — runs on a timer and automatically shut while the man was still inside.
“We called our Rescue Units. Our Rescue Units have the capability with their tools to breach walls of this vault. The process was started to breach the wall of the vault; it’s about 30 inches or so of concrete. We got to the metal plating and determined at that point, after about 10 hours, we would hold off and see if the doors would open automatically,” said Deputy Assistant Chief John Sarrocco. “The problem with the plating is we’d have to use the torches and it would affect the environment of the person inside the vault. This morning, at about 6:15, the vault opened on its own and the customer was released.”
The man was evaluated by EMS."
In retrospect, maybe they should have used the through-the-lock technique.
