HOUSTON (AP) -

A worker in Houston has been hospitalized after a circular blade became detached from a power saw and became impaled in his chest.

Houston fire spokesman Kenyatta Parker said  firefighters were called Monday morning about a man hurt while working atop a building. He said the unidentified man was using a saw that construction workers often use to cut through metal or concrete.

He was transported to a hospital with at least part of the blade still embedded in his chest. Parker said the man was conscious but his condition was not known.
    
The man was working on a building near The Galleria, a popular shopping center.
    
Parker said such a blade can become dislodged if it isn't tightly secured while cutting a hard material.
