West Springfield firefighters and hazmat teams are on scene of a hazardous materials spill inside a tractor-trailer at a warehouse for the Crystal Companies on Bliss Road.
Crews have been there on the scene for several hours.
Fire officials say two employees of that company opened the door to the tractor-trailer, and saw some sort of chemical had spilled and a vapor cloud.
That's when emergency crews were called.
The company is in a business district and the CBS 3 crew on the scene says there are no homes nearby.
No one has been evacuated. As of 1 a.m. Wednesday, Hazmat crews had started decontaminating people who may have been exposed to the chemical.
CBS 3 will have the latest details as they become available.
