MIAMI (AP) - Engineers and safety officials are inspecting all stages at the Ultra Music Festival after part of a giant screen fell and injured three workers.
The workers were hoisting up one of several LED screens at the main stage of the electronic dance gathering Thursday night when it fell.
Lt. Ignatius Carroll, a Miami Fire Rescue spokesman, says one person was critically injured. Another was seriously hurt, and a third sustained minor injuries. All were stabilized after being taken to the hospital.
City engineers, fire rescue officials and Occupational Safety and Health Administration representatives are reviewing all the stage setups as a precaution. Carroll says all three agencies must sign off before the festival begins.
The festival is scheduled to begin at 3 p.m. Friday. It is expected to draw 330,000 people.
