Aerial video showed a large construction site with multiple cranes. At least one Boston police cruiser could be seen parked outside.
People who live in the area say they heard workers screaming and saw the first responders rush in.
"It is heartbreaking. I mean, they work so hard, and it's such a dangerous job," said one woman who was visiting family on East Canton Street Thursday. "You just hope that they use all the safety precautions and try to ensure that the workers are safe."
The incident happened just a day after three workers were injured in a construction collapse at a former power plant in South Boston.
