INDIANAPOLIS (AP) — Nine workers at a Rolls-Royce aircraft-engine assembly plant near the Indianapolis International Airport were injured Friday when a tank of nitric acid exploded and filled the building with a cloud of corrosive vapor, officials said.
None of the workers suffered life-threatening injuries when the 250-gallon tank exploded about 1:30 p.m., Capt. Mike Pruitt of the Wayne Township Fire Department said. The explosion released a vapor cloud that left the workers with burns and breathing problems.
Pruitt said eight workers were taken to local hospitals. Seven were in good condition, and the eighth is stable and had no serious injuries. The ninth person was treated at the scene.
The cause of the explosion — and how much acid was released — remains under investigation by Rolls-Royce and fire officials, Pruitt said.
