Officials now say an incident that forced fire and hazmat crews to Air Products in Allentown wasn't as serious as first though.

Fire crews were originally dispatched to the company, located on Hamilton Blvd., for an unknown incident. Hazmat crews followed after one employee had to be transported to the hospital after becoming sick. The building was also evacuated.

The employee, who was in a research and design business, was exposed to a small amount of a spilled chemical, officials say.

The employee was evaluated and released and the building has reopened.
