Explosion Investigation at New Hampshire Ball Bearings Continues

Peterborough - New Hampshire State Fire Marshal J.William Degnan and Peterborough Fire Chief Joseph P. Lenox III announce the investigation into Monday's explosion at New Hampshire Ball Bearings (NHBB) is continuing.

As a result of the on-scene investigation and examination, this incident continues to be classified as an industrial accident. The cause of the explosion has been determined to be directly related to a Nitric Acid reaction. Nitric Acid is an oxidizing agent and is commonly used in industrial processes.

Late last evening the on-scene portion of the investigation was completed, and the facility was turned back over to NHBB management so they could begin remediation and clean-up. Clean Harbors Environmental Services will be assisting NHBB with this effort over the next several days.

The investigative team, made up of members from the NH State Fire Marshal's Office, OSHA, and personnel from the NH Department of Environmental Services (DES) will continue to conduct interviews and analyze documents, samples, and other evidence collected at the scene over the next several weeks. A final report regarding the exact origin and cause and any recommendations as a result of the investigation will also be several weeks away.

Any further inquiries can be directed to the State Fire Marshal's Office - Bureau of Investigations, District Chief Keith Rodenhiser at (603) 223-4289.
