ASHLAND – Police and Fire were on the scene for about 5 hours for an industrial explosion at Kidde Fenwal at 400 Main Street.

“It appears an explosion occurred in an underground service line to a production warehouse from a Carbon Dioxide storage tank. The tank was unable to be shut down and hazmat teams and the facilities gas contractor conducted venting operations to safely drain the tank. The incident will be investigated by the facility,” said the Ashland Fire Department.
