An explosion yesterday rocked a small-town New Hampshire plant that manufactures ball bearings, shaking walls, shattering windows, and sending at least 15 people to the hospital, but a company spokeswoman says none of their injuries appeared to be life-threatening. Hazardous-materials teams responded after the blast at the New Hampshire Ball Bearings Inc. plant in Peterborough, but firefighters said there didn't appear to be any environmental damage.
The blast blew out windows on the three-story building's ground floor, a fire department spokesman says. There was heavy explosion damage, and the first arriving firefighters saw a column of smoke. The cause of the explosion was under investigation, but all indications were that it was an industrial-related incident, the spokesman says. At the time of the blast, around 450 people were working in the plant, which manufactures high-tech parts for the aerospace industry.
