Dangling man rescued from building's 12th floor

A man dangling from the 12th floor of a Miami building has been rescued after scaffolding he was working on collapsed beneath him. 

The collapse, on the side of a Key Biscayne resort, left the worker strung up by his harness on the ocean side of the building.  

Instagram user ironroch filmed the hour-long rescue from the Grand Bay Resort, showing the petrified worker beginning an assisted descent down the window. 

Fire crews told local news the man seemed calm, and his initiative to rest his foot on a window meant the rope wasn't under such extreme stress. 

It's not yet known what caused the accident, but the unidentified man was taken to the Jackson Memorial Hospital for a once-over, after reporting numbness in one of his legs.
