FAIRFIELD, Conn. – A chemical spill at General Electric’s Fairfield headquarters leaked 500 gallons of nonhazardous materials Thursday evening, according to the Fairfield Fire Department. The fluids drained from a broken pipe in the corporation’s utilities area into the storm drain system before fire crews could get the leak under control.

The chemical involved was Dowfrost, a heat transfer fluid. It is classified as “practically nontoxic to aquatic organisms,” according to the safety sheet published by its manufacturer, the Dow Chemical Co.

Fairfield fire crews built a dam to prevent the spill from spreading before cleanup crews arrived. State Department of Energy and Environmental Protection workers were also on the scene to oversee the cleanup process. No one was harmed during the incident or the cleanup process.

“Due to the non-hazardous nature of the materials involved, this situation was ultimately a good test of GE’s and the Fairfield Fire Department’s hazardous materials response partnership," Assistant Fire Chief Scott Bisson said in a statement.
