At least three children have been left injured, including one seriously, after a floor collapsed at a Colorado house party, according to firefighters.
The South Metro Fire Rescue (SMFR) was alerted to a report that “people were dying” at a home in the 20900 block of Princeton Place, in Arapahoe County, at around 9:30 p.m. local time on Saturday.
An SMFR spokesperson said a video posted on social media showed a crowd between 100 to 150 people jumping on the first floor before the collapse happened.
Many people then “violently” fell into the basement, which scattered a large amount of debris among the party attendees.
An SMFR Facebook post, which was shared on Sunday, read: “A 911 caller reported that ‘people were dying’ and hung up. Upon arrival, emergency personnel observed over 100 juveniles in the street and discovered that a large portion of the first floor collapsed into the basement.
“Additional resources were dispatched and witnesses reported that five people were trapped in the basement. Firefighters entered the badly-damaged home and immediately began search and rescue operations.”
Outside, paramedics found a victim who had suffered serious injuries and transported them to a nearby hospital.
Emergency services then found a ruptured natural gas line was free-flowing and needed to be shut off in order to prevent an explosion as well as a fire.
An SMFR technical rescue team and the Arapahoe County Sheriff’s Office assisted firefighters in the search of the home, according to the Facebook post.
While they found a lot of debris, the SMFR determined no one was trapped inside the home and that everyone had left the house.
They found two other victims outside with minor injuries and they were also transported to a hospital.
Photos shared outside the building showed numerous firefighters, fire trucks and ambulances outside of a home.
An SMFR spokesperson added: “It’s truly remarkable that no deaths or additional injuries occurred.”
The spokesperson later told Newsweek: “I can confirm there were three juveniles injured, treated and transported to the hospital by South Metro Fire Rescue.
“The person who was transported with serious injuries was stable. I have seen social media comments that mention additional juveniles were injured, but those individuals left the scene and did not ask responders or call 911 for help.”
According to Buildings.com, an online community of facility managers, there is no way to absolutely guarantee against collapse but said some steps can be taken to prevent progressive collapse.
The website suggested the following steps:
- Make sure vulnerable locations, such as perimeter beams are designed to withstand shear load in excess.
- Verify the construction plans as design modifications can be made during the building process.
- Evaluate your existing structures, including reviewing documentation and materials used.
- Carry out an assessment of the existing capacity of structural systems.
