The Bethel Fire Marshal's Office has determined that the massive May fire at Clarke Business Park likely started because of an electrical issue with a heat tape machine, for shrink wrapping material.  The fire started accidentally.  It was a Sunday and took more than 100 firefighters 8 hours to extinguish.  Adhesive tape company ATP remains displaced from the front of the building, where the fire started.  The back of the building sustained smoke and water damage because it was protected by a firewall.  Intersurface Dynamics reopened a few days after the fire.
