A construction worker sustained a concussion shortly before 11 a.m. yesterday when a concrete pumping hose fractured on the second floor of the College of Law building.

Alfred Moreno, an employee of Prairie Concrete Construction, was transported to University Medical Center with a cut, concussion and some concrete in his eyes, said Paul Carlisle, the Law College site supervisor.

A UMC nursing supervisor said Moreno was treated and released yesterday.

"Part of the pump hose actually fractured and a coupling flew over and hit him in the head," Carlisle said.

Moreno was struck on the right side of his head and sustained a laceration, said Sgt. Vincent J. Roberts of the University of Arizona Police Department.

University police officers called a Tucson Fire Department ladder truck to the scene at 1201 E. Speedway Blvd. because the paramedics' stretcher would not fit in the building's elevator, Roberts said.

The ladder truck blocked southbound Mountain Avenue until about 11:15 a.m. when both it and the ambulance left the scene.
