PETERBOROUGH, N.H. (AP) - Some of the workers idled after an explosion tore through a New Hampshire ball bearing factory earlier this week will be back on the job Thursday.
Investigators said Wednesday the explosion was caused by a nitric acid reaction, which is commonly used in industrial processes. They said the on-scene investigation was done late Tuesday and the building turned back over to the company for cleanup and repairs.
In a letter to employees posted on its website, company President Gary Yomantas said workers would be paid the regular wage for time missed since the explosion occurred Monday afternoon.
All shifts were canceled Tuesday and Wednesday at the Peterborough plant.
The blast shattered glass, dislodged ceiling tiles and damaged walls.
The plant makes parts for the aerospace industry and employs 700 people.
