Manufacturing, Manufacturing Plant Redding, CA – Sprinklers keep fire from spreading at manufacturing plant May 26, 2015 viking210 A fire in a tank of detergent was doused Sunday by the sprinkler system at a Redding manufacturing plant, a Redding Fire Department official said. Shortly after 5 p.m. a fire alarm went off at Seco Manufacturing on Oasis Road, Battalion Chief Steve Reilly said. The fire alarm was activated by a fire in a tank of detergent used in a process to anodize aluminum that is used to make surveying equipment, he said. A fire sprinkler turned on above the tank, keeping the fire from spreading, he said. Shortly after the fire broke out, firefighters with Redding’s Engine Co. No. 6, which is across the street from the plant, heard the fire alarm and saw a light smoke coming from the rear of the business, Reilly said. The firefighters got access to the rear of the building and were able to put it out by about 5:30 p.m., Reilly said. The business was closed for the Memorial Day weekend. The fire was confined to the tank, he said. He said the fire was caused by a malfunction in how the tank operates.
