Manufacturing, Manufacturing Plant Forks Township, PA – Polystyrene fire at plastics manufacturer controlled by sprinkler system May 17, 2016 viking210 A Sunday morning fire at a Forks Township manufacturer could have been much worse if not for the building’s sprinkler system, a township fire official said. Crews were called for the fire at about 12:15 a.m. at the Ecopax building, 3600 Glover Road, said Matt Mowrey, deputy chief for the Forks Township Fire Department. Ecopax manufactures foam and plastic food containers. A commercial roll of polystyrene caught fire, leading to a working blaze, but the flames were kept from spreading by the building’s sprinklers, Mowrey said. The cause of the fire has not yet been determined, and the blaze is under investigation, Mowrey said.
