NASHUA, N.H. --
An explosion in Nashua on Saturday morning severely burned two people and injured two others.
At least four people are hospitalized after an explosion in Nashua, police say.
Firefighters described the blast as a quick flash just after 9 a.m. at the Worthen Industries plant at 3 E. Spit Brook Road. Nashua police described the incident as an industrial accident. Fire officials and federal inspectors are expected to investigate a cause.
Firefighters said people were welding inside the building as part of maintenance work on an empty holding tank inside the factory. Firefighters said the blast happened so quickly that the fire was out before fire trucks arrived.
Two badly burned workers were flown to Boston hospitals for treatment, and two others were taken to nearby hospitals for treatment. Their identities and conditions were not immediately released.
"Their injuries, although (they) appear to be of concern, (are) not as severe as the others who were injured," Nashua Deputy Fire Chief Michael O'Brien said.
Firefighters said they think most of the people inside were working on maintenance projects at the time of the accident and that the factory wasn't operating.
From outside the building, it was nearly impossible to tell an explosion occurred. Electric, water and gas lines were checked and considered to be safe. Firefighters also said the building is stable.
"The company, right now, is shut down during this particular investigation, and after the investigation is complete, I'm sure they'll come back to some sort of cleanup operation," O'Brien said.
The company makes glues for other factories that make things like shoes and sofas.
