“A woman was reported to have fallen a pretty good distance, some estimates are as much as two stories,” said West Valley City Deputy Communications Director Roxeanne Vainuku.

Vainuku said the employee had been working on scaffolding on the outside of the six-story tall building at the time, but she wasn’t sure how high up.

Three West Valley City firefighters loaded the worker onto a gurney and were bringing her down an interior staircase when Vainuku said, “They got to the final floor of the building, the staircase collapsed, and the firefighters and the patient all fell that final story onto the floor.”

One firefighter was flown to the hospital by medical helicopter, because Vainuku said his injuries were so severe. The other two, she said, suffered less serious injuries and were taken to the hospital by ambulance.

The employee was also taken to the hospital by ambulance, but there were no updates on her condition.

Vainuku said the West Valley City building inspector and OSHA, as well as were on scene Monday night investigating how the staircase collapsed.

“These folks go in to help someone else out,” Vainuku said, “and it is tragic to see that not only was that person further injured in this fall, but also our firefighters who were trying to rescue this person were actually injured as well.”

The incident remains under investigation.

Obviously WVC FD is extremely distraught. PD still gathering all details, including injuries for the 3 fire fighters and 1 employee, and everyone's condition. @KSL5TV pic.twitter.com/W5kYc2Srz1
