They broke another fire-fighting stand pipe at the star-crossed former Deutsche Bank building near Ground Zero.

This time, happily, the damage was discovered right away, before anyone’s life was placed at risk.

The break occurred Thursday, as workers were doing whatever it is they do at the site.

You’d think someone would be guarding that thing with his life at this point. After all, it was a sawed-off standpipe – used to deliver water during a fire – that led to the deaths of two firefighters during a 2007 blaze at the building.

True, this time, alarms did go off; thank goodness for small favors.

But this was just the latest in a line of “accidents” at the building since it was damaged irreparably on 9/11 – many of which did involve injuries.

Not to mention the fatal ’07 blaze.

And none of these would have happened if the building had been taken down promptly.

Alas, demolition of 130 Liberty was left to local officials – most recently, the embarrassingly inept pencil-pushers at the Lower Manhattan Development Corp.

Thus, 7 1/2 years after 9/11 – and 1 1/2 years after the deadly fire – the building yet stands. Indeed, not a single floor has been removed since the fire.

Yes, that the pipe was cut a second time is stunning.

More stunning, though, is that City Hall puts up with such nonsense.
