Apartment Building, Residential Westford, MA – Sprinkler system puts out apartment fire before it can spread October 21, 2015 viking210 A fire was reported at a three-story apartment building on 3000 Princeton Way in Westford at 11:46 a.m. on Oct. 20. “Our investigators are there, but there isn’t a cause yet,” said Westford Fire Department Shift Captain David O’Keefe. The fire occurred in a second floor single bedroom, but the building’s sprinkler system put out the fire before it spread. The Westford Fire Department had to call for mutual aid from surrounding towns because the department’s ladder truck is out of service, according to O’Keefe. “Unfortunately, our ladder truck is out for servicing, so we had to call the Chelmsford ladder truck,” O’Keefe said. However, the Chelmsford ladder truck was not needed before it even arrived. “At that point, the fire was already knocked down,” O’Keefe said. “The sprinklers put it out.”
