EAST RUTHERFORD, N.J. — Federal investigators believe a newly installed dust collector was the probable fuel source for an explosion and fire at a New Jersey ink manufacturing facility in October, NorthJersey.com reported.
Seven workers were injured Oct. 9 when a carbon compound used to make newspaper ink ignited in ductwork at the Sun Chemical’s US Ink plant.
According to investigators, the evidence points to a chain reaction set off by a dust collector installed on the roof about a week before the explosion.
The Occupational Safety and Health Administration (OSHA) is investigating the incident and has six months to report its findings.
Most of the plant has been reopened, but the explosion area will remain closed until the investigation is complete.
