Two other workers had minor injuries and were taken from the scene immediately, Dempsey said.
Dempsey said a large piece of cantilevered flooring fell, forming a void and trapping the worker’s lower legs.
About 100 emergency responders helped in the rescue, including EMTs and paramedics who helped the victim with pain management. A surgeon was also brought to the scene due to the seriousness of the victim’s injuries.
Boston Mayor Michelle Wu on Wednesday thanked emergency responders.
“It is a near miracle that our third person was able to be transported to the hospital safely, and we are sending every prayer for a quick stabilization and recovery,” the mayor said.
Dempsey said the building is old and weak, and “demolition jobs are dangerous.”
The worker who was trapped was conscious throughout the rescue, he said.
