PROVIDENCE — A dramatic rigging collapse at the Ringling Bros. and Barnum & Bailey Circus Sunday sent eight aerialists plummeting to the ground as families watched in stunned confusion.
All eight — who had been hanging by their hair from an umbrella-shaped rigging — were seriously injured, suffering broken bones, head injuries, and lacerations in the 30-foot fall, officials said. A performer standing below was also seriously hurt.
“There were just girls laying on the floor,” said Eddie Brundage of Wareham, Mass., who was with his wife and daughters, ages 3 and 4. “We took our kids right out; we didn’t want them to see.”
“It’s traumatizing for the kids,” said Joseph Shoafi, who attended the circus with his wife and their three children, ages 3, 5, and 8.
Federal workplace safety officials said they would investigate whether any workplace safety violations caused the accident. The inquiry could take several weeks, a spokesman said.
The act, called the “hair hang,” is performed by a troupe of women from places around the world including Brazil, Bulgaria, Ukraine, and the United States, according to the Ringling website, and was created by Andre and Viktoria Medeiros.
In an interview April 24, Andre Medeiros told The Youngstown Vindicator, an Ohio newspaper, that he expanded the act from two to eight performers.
“It’s really dangerous,” Medeiros said. “Everything that’s new has a really high risk because we created something. It wasn’t like we could copy another act.”
The performance took place during the midday show of “Legends” at the Dunkin’ Donuts Center. The metal rig used in the ‘‘hair hang’’ act collapsed at about 12:15 p.m., said Stephen Payne, a spokesman for Feld Entertainment, the parent company of Ringling Bros.
The injured women were taken to the trauma center at Rhode Island Hospital, said Fire Chief Clarence A. Cunha. He said police are also investigating the cause of the accident.
“When that’s determined, we will open the show again,” Cunha said.
A YouTube video of the accident shows a shimmering curtain dropping to reveal a ring of acrobats suspended in the air, facing outward — forming what resembles a human chandelier. One woman hangs in the center, just below the rest.
Seconds later, the rigging and the performers plunge to the ground, and the rigging lands on top of the acrobats. Circus music continues playing, but the main stage lights cut to black and a woman’s voice is heard saying, “Were they supposed to fall like that?”
Circus-goers described a chaotic and frightening scene after the rigging fell.
Ashli Croinex, 22, a Peabody, Mass., resident who was sitting about six or seven rows back, said that after the rig crashed to the ground, a performer who had been standing below was bloody and shaking.
She said that the performer was “the only one able to get up. The rest of them were just silent. They didn’t even move.”
Croinex said the audience was initially stunned.
“It looked like it was part of the show, and the whole crowd was silent,” she said. “Nobody even moved. It was so scary.”
Three ambulances drove into the circus ring, and the performers were carried out on stretchers, officials said.
Roman Garcia, general manager of the show, said all of the injured acrobats were conscious.
“We hope they will make a full recovery but, unfortunately, we don’t know if that’s going to happen,” said Steven M. Paré, Providence’s commissioner of public safety.
Lawrence Lepore, general manager of the Dunkin’ Donuts Center, said he did not know how many people attended the Sunday morning performance.
The center can seat 6,500 people, he said, but tickets were not sold out.
The circus performers, he said, are like “a big family. . . . These people travel together, they live together nine months out of the year. There are a lot of entertainers who are pretty upset about what took place.”
Circus workers declined to speak about the accident.
But circus performers and their friends peppered social media with testimonies and pleas for support late Sunday, with several people posting pictures of the Legends tour logo with the words “Prayers for” and “Circus Strong” pasted above the Ringling Bros. name.
Johnathan Lee Iverson, a popular ringmaster, posted a photo of the aerialists on Twitter and Instagram, and wrote, “In your prayers, kindly remember the ladies of the Medeiros Troupe & a dancer.”
Audience member Allison Katz, a Walpole, Mass., resident who was at the show with her 5-year-old son and 2-year-old daughter, described the scene earlier Sunday.
“They were about to start the stunt and the whole thing just dropped; the piece they were attached to dropped onto them, and it looked heavy,” she said.
She said it took first responders time to lift the rigging off of the performers. Katz took her children and left.
“I didn’t want my kids to witness too much,” she said. “It’s just really scary and sad.”
She added that her children keep asking, “What happened to the girls?”
Shoafi said after the accident that an announcer called for an intermission. About 45 minutes later, a ringmaster took the stage and told the crowd that the rest of the show was canceled.
The two other performances scheduled for Sunday were canceled.
The circus had three additional shows scheduled for Monday, and according to the website for the Dunkin’ Donuts Center the 10:30 a.m. show has been canceled.
Providence officials said that they would allow the other shows to go forward, but only if they do not include any aerial acts.
“We have yet to determine that cause of that collapse, and as a result, we have grounded any aerial acts for tomorrow’s show,” Paré, the commissioner of public safety, said. “They [the circus] will have to determine whether or not they’ll put on the shows.”
OSHA officials could not provide information Sunday on how common workplace accidents are among circus performers.
The federal Bureau of Labor Statistics showed 10 on-the-job deaths among all performing arts companies in 2011 and three fatalities in 2012, the most recent year for which data were available online.
In February, stunt rider Julian Gomez of the Kazim Shrine Circus suffered a brain injury after crashing his motorcycle into a concrete wall in Roanoke, Va., according to published reports.
