A wall of flame shut down Sullivan Road outside the Spokane Valley Honeywell plant and prompted a heavy response from the Spokane Valley Fire Department Wednesday afternoon. The fire consumed a long row of tall arborvitae bushes that lined the road. When crews arrived the bushes were a wall of flame and embers were blowing across the busy road, said fire department spokeswoman Melanie Rose. “We responded with a lot of units right away because of Honeywell and the types of hazardous chemicals they have,” she said.
