Businesses and a preschool were prepared for the worse in Montgomery Township when a suspected hazmat incident was believed to be unfolding at I-T-W Polymers and Coatings on Commerce Drive. Fire officials say, alarms went off just before two Wednesday, when a chemical reaction in a research lab caused gases to spread throughout the facility. Fire officials discovered that the gas was not a threat. Businesses and the pre-school stayed inside their buildings, shutting off heating and air-conditioning systems, until just after 3pm, when the incident ended. No one was injured.
