Police are investigating what they said is a small chemical reaction at Amberbelle Textiles on East Main Street in the Rockville section of Vernon after a worker mixed some lye and another chemical, according to the state Department of Environmental Protection.
Three people were taken to a local hospital because of breathing problems, according to local dispatchers, and East Main and Grove streets are closed. One of them was the employee who was mixing the chemicals, according to DEP. The mixing caused a chemical fog.
Nothing is yet known on the other two people.
The company makes high-tech fabrics for the Mars Pathfinder parachute, as well as leisure and recreational products.
Caution tape remains up at the scene.
More information will be posted as it becomes available.
