Manufacturing, Manufacturing Plant Plymouth, IN – Sprinkler system helps prevent damage from fire at fiberglass shop December 20, 2016 viking210 Employees at a manufacturing business in Plymouth are cleaning up after a fire in the fiberglass shop. Firefighters aren’t sure exactly what started it but employees at AK Industries say it was probably the chemicals used to make resin for the fiberglass. Those chemicals made for some thick, black smoke. Employees won’t be able to go back to work till the building is aired out. The fire chief says a sprinkler system prevented worse damage. “The fire was not out all the way. We went in and finished up with the sprinkler system could not get. So you know in a tight corners and crevices and things that we can’t reach we had to go in and dig it out,” said Plymouth Fire Chief, Rod Miller. “I thought the whole building was going to catch on fire. You know, this is where we work and it’s almost Christmas,” said steel grinder, Guadalupe Sanzhez. The building is in pretty good shape. Employees say they think they’ll be back to work soon.
