A fire broke out today at an Intel chip plant in Arizona, injuring seven people. However, the chipmaker said it would have no impact on production.

Intel&39's Fab 32 located in Chandler, Ariz.

The fire was in a "support building" next to an Intel fabrication facility--referred to as a "fab," Intel spokesman Bill Calder said in a response to an e-mail query. Among the seven injuries, one was serious, Calder said.

Five people went to the hospital, and the others were treated and released, according to an update from Intel late this evening.

The support area contains solvents used as part of the manufacturing process, according to Intel.

"This was a fire in a support building off of Fab 22 which is under construction," Intel said. "Fab 32, which is adjacent to this, was evacuated as a precaution but there was no impact to production and employees went back in a short while later. An investigation into the cause is continuing," Intel said.

Fab 22 is being "retooled" to manufacture Intel's next-generation 22-nanometer chips.

The Chandler area has approximately 9,700 Intel employees, making it the second largest Intel site and the largest employer in Chandler, according to an Intel "Fact Sheet."

Intel announced earlier this year that it will invest more than $5 billion to build a new chip manufacturing facility at its site in Chandler. The new Arizona factory, Fab 42, will be one of the most advanced, high-volume semiconductor manufacturing facilities in the world.
