Employees who were victims of a furnace explosion at a steel plant that had a history of dangerous run-ins with equipment have submitted a complaint in the Philadelphia County Court of Common Pleas. They say that the management at the plant “outrageously ignored” the hazards of the equipment they were working with.

The ArcelorMittal plant in Coatesville, PA had a history of endangering their workers, according to the suit. A furnace exploded in 2007 and killed one worker, injuring two others. Though the company paid for the damages and was responsible for the workers they did nothing to improve the safety of the furnace, states the lawsuit. Workers say they have not started checking for leaks or started doing precautionary maintenance work.

The same furnace exploded years later in 2013 and severely burned three workers with molten metal. Water had leaked into the D Furnace, an electric arc furnace, and caused it to explode. Matthew McNeal and Sean Flood suffered second- and third-degree burns and Mark Tarloski suffered second-degree burns. They also say that now they are suffering from psychological injuries from the trauma as well. These three say that though their company paid benefits after the 2007 explosion they seemingly did not do much of anything to make sure it did not explode again and have filed a suit against the company.

The lawsuit also calls out other companies who were involved with maintaining or manufacturing the furnace as defendants. They say they delivered a product that was unsafe and were negligent in keeping it safe.
