Communications between Miami-Dade first responders reveal the level-headed reaction as rescuers raced to the site of a collapsed high-rise apartment building in the coastal Florida community of Surfside.

The recordings detailed communications between dispatchers, hazmat units, firefighters and emergency medical responders who rushed to assess the damage and free as many survivors as they could from the crumbled Champlain Towers South building.

One firefighter reported arriving "at the rubble pile" with an engine and another vehicle.

"We’re gonna need some backboards," he says. "We’ve got two [victims] over here we’re gonna need to extricate." 

A different responder made a similar request.

"You’re gonna have to have all units bring all of their equipment up and stage it," one responder said. "We’re also gonna need runners – we’ve got multiple patients we’re bringing off this pile."

Another called for backup quickly after arriving at another side of the scene.

"I need two units with backboards to come to the south side… they’ve got two victims on this side," a member of the Hazmat group said at one point.

At another point, responders were ordered to evacuate the area of 88th Street and Collins Avenue, adjacent to the collapsed building, to make room for arriving police.

Minutes later, a rescuer said that same area was where they expected to pull out the most survivors.

Dozens of units from neighboring counties also aided the response, according to the recordings. 

Many were eager to help when they arrived, asking where they were needed.

At least one person died and 99 remained unaccounted for as of Thursday evening, and responders had pulled out at least 37 survivors.

Gov. Ron DeSantis warned that officials were "bracing for some bad news" based on the scale of the damage, even as he praised first responders for their bravery.

"They were on that scene before we knew whether there would be more collapse," he said. "We didn’t know whether the building had any structural integrity, and they were shepherding people to safety, and they absolutely saved people’s lives. We really appreciate all that they have done and they are continuing to do."

EXPERT EXPLAINS POSSIBLE REASONS BEHIND FALL OF CHAMPLAIN TOWERS

State and local officials have declared emergencies and rescue efforts were still underway more than 16 hours after the early morning collapse. 

During an early evening news conference, investigators said rescuers had heard "banging" sounds from within the rubble that could be signs of life.

Portions of the building that remained intact were evacuated and labeled uninhabitable.

The 12-story condo building had been built in 1981. It was part of a complex with two sister high rises, for a total of 342 housing units. More than 130 of them were in Champlain Towers South, which is the one that tumbled down.

Apartments inside ranged from one- to three-bedroom units and cost between $600,000 and $900,000, according to recent real estate listings. 

A South Florida-based home insurance inspector told the Miami Herald she visited the building in February 2020 to inspect impact windows and doors for a client. She said the building was made of reinforced concrete and should not have collapsed the way it did, the Herald reported.

Local regulations require oceanfront high rises to be reinspected every 40 years. The building was due for a new one.
