District Chief Gerry Morris tells CHSJ News police and fire crews arrived on scene just after 11am to find vapours coming from one of the tanks.
Morris says a perimeter was set up and the HASMAT Unit was called in as a precaution, but carbon dioxide is non-flammable and is only a threat in confined spaces because it gets rid of the available oxygen.
Morris says the leak was caused by an electrical problem in the plant and the vapours quickly shut themselves off due to a built-in safety system.
