Managers closed the Oxford Valley Mall in Langhorne yesterday morning after store employees showed symptoms of exposure to carbon monoxide.
About 7 a.m. yesterday, an employee of the mall's J.C. Penney Co. store called 911 complaining of symptoms of the odorless, colorless gas, according to Frank Farry, fire chief for the Langhorne-Middletown Fire Company. Eight people were taken to Frankford Hospital-Bucks County Campus, treated with oxygen, and released, said Maria Cerceo-Slade, a hospital spokeswoman.
A chimney on Penneys' roof had collapsed, sending carbon monoxide into the ventilation system, Farry said. The store will remain closed until at least today, he said, but the rest of the mall was reopened early yesterday afternoon.
