04/16/2018 - WHITMAN, MASSACHUSETTS (PLYMOUTH COUNTY) - Around 0830 hours on the rainy and cold morning of Monday, April 16, 2018, Patriots Day, the Whitman Fire Department struck Box-55 for a reported fire inside the building at 66 Pond Street. Car-3, Car-4, Engine-243 and Engine-242 responded. Ladder-246 was out of service for maintenance. Car-3 arrived on-scene and reported light smoke showing from a large one-story commercial building. A fire was found in the ventilation system at Computron Metal Products. Companies stretched a hand line off of Engine-243 and were able to knock down the fire quickly. Crews attempted to tie in to a yard hydrant at the property but were unable to get the front cap off the hydrant. A hydrant was tied into on Industrial Way, but was not needed. Companies worked to take apart the ventilation system where the fire had originated and removed it to ensure the fire was completely knocked down. Crews also checked vents on the roof, and found no extension. Fans were set up to remove the smoke condition from the building. Ambulance-249 responded to the scene with call-back personnel, and a Hanson engine covered Whitman's firehouse during the fire. The cause of the fire is under investigation. Plymouth County Sheriff's Department BCI unit was on-scene to investigate. No injuries were reported.
