Manufacturing, Power / Energy Facility Commercial fire contained by sprinkler system (Waseca, MN) September 4, 2012 viking210 A fire inside Emerson Network Power was contained to an assembly room. “The sprinkler system did its job,” Waseca Fire Chief Gary Conrath said. No one was working in the building when the fire apparently started in an electric panel box. So, if the alarm and sprinkler system hadn’t been working properly, the fire could have spread quickly through the large plant.
