4 dead after explosion at T2 Labs chemical plant in Jacksonville

JACKSONVILLE - An explosion and fire at a chemical plant killed four people Wednesday and injured at least 14, fire officials said. It was not clear what caused the explosion about 1:30 p.m. at the T2 Laboratories Inc. plant, which makes chemical solvents and fuel additives, said Tom Francis, a fire rescue spokesman. The chemicals at the plant made the environment "incredibly dangerous for the first responders," Francis said. "Explosions were generating all kinds of side brush fires and other kinds of blazes."
