OSHA has cited a manufacturer of polystyrene foam core board for willful, repeat and serious safety violations. The business faces a total of $105,490 in proposed penalties following two inspections by OSHA’s Hartford Area Office. The first inspection, begun on May 31, identified several deficiencies in the plant’s process safety management program involving the chemical isopentane, a flammable liquid used in the manufacturing process. OSHA found that the company did not inspect or test process equipment, including the isopentane tank, piping and pressure relief valves. This resulted in the issuance of one willful citation, with a $53,900 fine. One repeat citation, with a fine of $10,780, was issued for a lack of written procedures to maintain the ongoing integrity of process equipment. A similar hazard was cited in 2009. Six serious citations, with $26,180 in fines, were issued for incomplete process safety information, hazard analyses and documentation, and for lack of readily available fire extinguishers and fire extinguisher training. Here is a breakdown of the citations:
