A hazardous materials team was inside the building.Campanella said damage to the building was extensive but no dollar estimate was immediately available.Residents advised to stay indoorsAuthorities blocked roads into and out of the area and advised nearby residents who remained in their homes to close windows and turn off air conditioners, Campanella said.Berthoud Fire spokeswoman Chloe McKinley said the explosion was caused when a delivery company unloaded chemicals at the plant that were not compatible with other chemicals.Judy Dahl, business manager for the Little Thompson Water District, one of the operators of the plant, confirmed a truck was unloading chemicals at the time.Dahl said no water-quality problems were expected because other plants in the system were still operating.Chlorine is used to disinfect water but is toxic as a gas and poses a serious risk of fire and explosion.
