MIAMI (CBSmiami) — Miami and Key Biscayne fire rescue crews rescued a man seen hanging from a building in Key Biscayne. The person was hanging from the 12th floor because of a scaffolding collapse. The crews rappelled him down to the ground, placed him on a gurney and wheeled him into an ambulance. He was taken to Jackson Memorial Hospital for treatment. “We went ahead and established communication with him, saw how he was, saw where he was and the harness that he permanently has was secure enough til the City of Miami TRT specialty team arrived to assist us,” said Key Biscayne Deputy Chief Marcos Osorio. His condition is unclear. Earlier, fire rescue crews could be seen speaking to the man from a nearby balcony. He did not seem to be injured and seemed to be calm. It’s unclear how many people were on the scaffolding when it collapsed. The Occupational Health and Safety Administration has opened an investigation. No further information was immediately available.
