Saturday, a portion of a heating and ventilation system at a resort pool in Aurora, Colorado, collapsed, injuring six people, including two in critical condition.

The collapse occurred at approximately 9:50 a.m. on Saturday at the Gaylord Rockies resort near Denver International Airport, according to Aurora Fire Rescue.

Sherri-Jo Stowell, a spokeswoman for the agency, stated that large metal ductwork and mechanical parts that were mounted on the ceiling fell onto the pool deck and into the water, covering nearly the entire pool.

She stated that the victims’ injuries varied from penetrating wounds and slashes to “injuries consistent with being crushed.”

The collapse occurred while employees were running up and down the resort’s staircases for physical training, according to Fire Chief Alec Oughton.

A resort attendant who answered the phone when a reporter seeking comment called hung up on the reporter.

Oughton stated that the resort will investigate the cause of the collapse and will be responsible for preventing visitors from entering the pool area.
