A man was in intensive care at a Dayton hospital with a serious head injury after an industrial accident at a Springfield block and brick plant Friday afternoon.

Springfield Concrete Block & Brick Owner Robert Anderson said that off-duty employee Matthew Clay’s head was pinned between a break in a wall where the company rolls products out of the building and a stacked load of cinder blocks being rolled out.

It was not immediately clear how or why his head may have been in the area, police said.

“We don’t know whether the victim intended to enter the building again between those blocks or just sticking his head in to try to say something to his friend who was operating the blocks on the rail,” Springfield Police Sgt. Barry Eggers said.

Clay, 25, of Pleasant Twp., was reportedly at the business, 1100 Mitchell Blvd., on his day off to pick up his paycheck.

“It’s my understanding that they routinely go in and out of there, but they do it on the (left) side; it’s 12 inches wide. But the side he was on is half that width,” Eggers said. “I don’t know if this young man knew that because he’s only been here two weeks or if he’s just hoping to say something quickly and get out of the way.”

“I don’t even know what he was trying to do,” Anderson said. “I’ve been here since ‘67 and never had anything like that happen.”

His condition was listed as undetermined about 5 p.m., according to a Miami Valley Hospital spokeswoman.

“The hope is he recovers and can tell us what his intent was,” Eggars said.
