OSHA cited a paint plant for 26 health violations after a cloud containing flammable vapors was released from the company’s Columbus facility on March 21, 2012. OSHA initiated an inspection under its national emphasis program (NEP) on process safety management (PSM) for covered chemical facilities. Proposed fines total $138,600. The vapor cloud was caused by a copolymer reaction of flammable chemicals when over-pressurization occurred in the equipment. No injuries were reported.
