MIAMI (CBSMiami) – Six construction workers were injured Wednesday morning after a large bundle of rebar fell on them at a construction site in Brickell, authorities said.

It happened just before 11:30 a.m. at a building that is under construction in the area near Brickell Plaza, between 8th and 9th streets.

CBS4 cameras captured images of a victim carefully being hoisted away in a basket with a Miami firefighter attached to it.

“Total shock for the people working in Brickell,” said Miami resident Roberto Arguelo.

“My initial reaction is I hope for the best for the people transported and this type of accident should not happen in the US,” said Arguelo.

Fire rescue officials say six workers were rushed to the Ryder Trauma Center in serious to critical condition after the accident at the site where offices are under construction.

“We were told a bunch of rebar was being transferred from a ground floor level up to a construction site level and there was some type of malfunction which caused the bundle to fall on 6 construction site workers,” said Lt. Pete Sanchez of Miami Fire Rescue.

Three of the workers appeared to be severely injured.

“There was 3 that were transported and by the time our workers got to them one had self extricated and two of the construction site workers were impaled on the rebar and we had to use a joint effort of some special operations teams and heavy rescue to be able to get these patients out safely,” said Sanchez.

“We were able to use our own tools to let them free.”

It’s not known how this happened.

“We have the building department on the scene and police and everyone is here to determine what caused this accident.”

Sanchez says firefighter-paramedics had to move quickly.

“It can always turn out worse but luckily today we were able to get all patients and again our units worked diligently to free those trapped and I hope all will be OK.”

OSHA, the Occupational Safety and Health Administration which investigates workplace safety was called to the scene.

The city’s building department is also involved with the investigation.
